ThermaSol® Steam generators

ThermaSol® Steam generatorsNote: Any Thermasol® generator sold from an unauthorized dealer on the internet the manufacturer will not honor the warranty and they are super strict. I have 3 sources that I know that are not authorized dealers and they get Thermasol® steam generators shipped from the local brick and mortar dealers that do not sell on the net. There are many loopholes to get this brand at a discount or if buying from certain places and you don't care about the warranty which can greatly lower the upfront costs. Can someone say ‘gray market dealers’. It’s one of those situations that if you really want it and can't afford it, you have to take a chance buying. They are all brand new and they work but if warranty is really important to you, then pay the full price. Something to consider is that Thermasol’s almost never have problems with them so utilization rate of warranty is already very low. With that being said, below is my review:

Consumer Notice: If a Thermasol® steam generator is not sold by an authorized dealer you will not have a warranty from the manufacturer. You can always confirm or know the serial number of the steam generator from the manufacturer's email to verify if you get a steam generator it will be warrantied. With this being said, beware of websites that give really cheap prices and when you call them they take your order for it and then say its on backorder just to then sell you a cheap Chinese import. I hear it all the time. It happens almost every day.

I have to say that this brand has the most consistent constant rate of steam of all the generators I have tested. There is never a time where there the room goes from either really hot to warm with extra steaming kicking in noticeably. In fact the most common “complaint” is that people don’t think there is any steam in the room because of the high level of dryness fraction and perfect consistent output! All one has to do is open the steam/shower door and the rapid change in air temperature will suddenly condense out the steam and you will see it was there all along! You can check the steam bath every 2 minutes with the humidity or laser thermometer and it’s pretty much the same within a few degrees every time I walk in both at ceiling and floor level.

​The Thermasol® brands are known for all their fancy techie features but one of the most important ones in terms of product durability or longevity along with operational costs is their high end heating elements. They have the lowest watt density of all generators. The grade of the steal used is a very important factor with this.

Note: if you are in NYC, there are stores that sell these. If you are coming in for a Thermasol® they will probably try to sell you one of those 10,000 dollar toilets that will wipe your ass and spray you down. For 10 grand, they better do more than that.

The Thermasol® is not exempt from scaling. I strongly recommend an inline water filter or a 5 gallon gravity fed bucket hooked up if you want to use spring water. (For those that can afford a Thermasol® I'm sure you don't mind steaming the room with Evian. Heck, why not Cloud Juice or some other ultra low TDS water. Putting tap water in an expensive generator like this is not a good idea. The heaters cost too much to replace with this brand.

Note: for homes that have a lot of electrical stuff plugged in on the same electric line, having a Thermasol® generator usually will require a dedicated line. Especially if you are considering Exercise with Oxygen Therapy (EWOT) like I advise my health clients which requires also running and an oxygen concentrator on the same line.

Customer service:
In my experience I mostly deal with people that want to get a cheaper steam generator. I'd say about 75% of the people would rather pay a much lower price up front and if there is an issue they will pay for the part and servicing. This strategy might make sense for the first 6 years or so but after that point it might have been better to go with a Tier 1 brand that has better longevity as the return costs to the factory, parts, labor, and inconvenience of interruptions etc. can start to add up. It really depends on for how many decades you plan to do steam therapy.

I will say that everyone that calls the Thermasol® company has told me they really know how to talk up their generators. They never trash talk competitors..Actually to be fair all Tier 1 brands follow this policy, I have called up and tested their sales and customer service people to try to get them to put down other competitors and they never have. I have never had one single complaint Thermasol being pushy or used car salesman like.

They do have a lifetime warranty on their generators (heck, for a steamer twice to three times what most people pay they should have this). Their no questions asked servicing is true not just some over used marketing lingo. As I never hear anyone ever complaining about one of their steamers breaking down (with the exception of some commercial applications), the warranty in my opinion doesn't matter since their generators are over built. Most people that have mentioned they have a Steam Room along with their Infrared Sauna have mentioned this brand when I emailed everyone that mentioned steam in my contact forms/Questionnaire on my infrared sauna review website.

Note: make sure you read the fine print as it’s clear and all but the life time warranty is only for residential people, not if put in a gym where it’s used in some of those 24 hour fitness places.

Thermasol has been around since 1958. They invented the first portable steamer for home showers.

As far as fluence levels, their generators use less water that most steamers in a 20 minute session. Water usage and efficiency is another one of those silly features that each brand tries to play up when the truth is that people blow through hundreds of gallons between showering and flushing toilets or watering lawns etc. Even the least efficient steam generators are efficient compared to other things we all use water for. Also consider if you have a reverse osmosis filter how much water that wastes for just one gallon of clean water…

My steam analysis of Thermasol has shown it has a much higher dryness fraction with a better latent heat index for more rapid sweating and easier breathing. You can also program the time on it so when you wake up in the morning at 7am the steam has been on for 10 minutes and all the seats are warm. It’s not cool when the steam feels good but the seats and walls ice cold!

ThermaSol® Review

Although I am not a fan of pressurized steam, I have to say this is the best brand for those that want
​a continuous, constant steam but only considering the pressurized types. The ThermaSol® works with 2 tanks unlike the other Tier 1 generator (Mr. Steam) that I have also put in tier 1. This has the least variance of temperature. It might not be as few as 6 degrees but definitely a step above all the rest I have compared at the same wattage. The ThermaSol® dryness fraction is my 2nd driest steam of all the generators I have compared. I compare this very closely with the other two tier 1 brands (Mr. Steam and Steamcore). Since the ThermaSol® has a lower humidity which is hard to get, it splits up the steam in 2 tanks so the steam is not so wet. While one is releasing, the other is boiling instead of dumping everything from one tank all at once weather it is 90% vaporized water or even less. This one is almost as dry as the open tank non pressurized steam but has a slightly higher latent index from my reviews.

The ThermaSol® is made in the USA. It is really made in the USA, not just having the parts from China and just assembled here. The ThermaSol® has the lowest watt density of all the pressurized chambers I have tried.

The cleaning system in theThermaSol® is really good. I rarely hear stories of limestone buildup as their auto flush is super high end. I urge people that don't have a water softener to get one. They do not have surgical steel elements, only stainless steel. There are more expensive 304 grade surgical steel heating elements that are highly resistant if someone is using hard water. These are the most expensive heating elements I have compared (See my heating element review).

Note: I urge people buying this steam generator to get a pressure reducer that will add years to the life of the generator. Home Depot sells them. Also, as pressurized steam can be noisier than the open tank non pressurized steam, I urge people to make sure the person installing the generator has 3/4 inch piping or 1 inch if an even quieter experience is demanded.

Since this is a more constant steam, many people tend to stay in longer than the steam generators that dump steam from one boiling tank and it gets really hot that is not balanced. This is when wet steam happens. The steam coming out of the generator is coming out too much at once quicker than the steam can condense in the room. The last thing I want is my blood pressure to get to 150 beats per minute before I can enjoy the steam. A good constant steam is the steam people looking for a ThermaSol® should expect.

About the ​ThermaSol® steam, since it has 2 highly efficient boilers, it doesn't waste as much water as the single tank pressurized generators. The steam is very easy to breath since it is much drier than the single tank types that many people are used to at their gym. You will never need to pour water on the sensors to get a constant steam. The ​ThermaSol® is the best pressurized steam generator that has this mastered. It has a higher dryness fraction if the room is actually sized right. The latent heat index is much lower than the single pressurized tanks and its much easier to breath in their steam. I recommend the ​ThermaSol® and have put this in Tier 1A which is the highest rating that I have for pressurized steam generators. 

Note: most people calling me for steam generators get the wrong kilowatt size based on sizing charts. There are many other considerations to consider. Please see my new updated sizing chart if interested in a ​ThermaSol® and I will choose the right size based on your answers.

Thermasol Pricing -
I guarantee the lowest prices through any of the Thermasol steam generator suppliers I work with. I looked up on Google to see what stores are paying to advertise Thermasol. People complain to me that these steam generators are expensive. Look at how much stores are paying per click to get your business. It costs 10 to 15 dollars every time someone clicks on their brand name key word. Dealers are fighting for your business. If I had to pay a 1,500 dollars a day for 100 people to click on my site I would have to charge more too. 

So, I dare anyone to contact me and compare my price with any other dealer. I have never been beat on my my price on the first quote. I have even lower prices on scratch and dents. See my page on scratch and dents.
Takes just a couple of minutes!
This quiz will isolate all steam-relevant issues and help me pick the right one based on your answers.

I will contact you personally and help you find the best deal on your new steam generator.

See our latest Review Page
Things to consider:
1. How fast the steam disappears. The dry steam will linger much longer as it is much lighter. Imagine taking a spray bottle and spraying water into the air. That will make the steam more wet and humid. This is the type of steam that I try to avoid. The heating elements that have more surface area touching the steam and the wattage is spread out over more heating element the dryer the steam it should be.

Note: There are 2 way to heat up a person's core temperature in a sauna. One is having too much latent heat and it heats up the room and walls. The room is almost hot as a sauna even when the steam has all disappeared. The other is from dryer heat that has low moisture and the walls aren't as hot and the vapor in the room heats the person, not just latent heat. The driest steam comes from open boiler tanks, not closed pressured water tanks that release all the steam in one load. This type usually has a 50 50 duty cycle meaning that it is on half the time and off half the time. This is one of the biggest complaints on these types of generators.

​2. Temperature variance: Some generators make the room super hot to the point where it burns my nose to breath in the steam and then the steam disappears and the steam generator kicks back on when the boiler is ready to dump. The Thermasol has a continuous steam with 2 boilers (a small and large one) so it always can produce steam. The type that has a 3 degree variance is from the open boilers and has the driest steam. Too wet of steam does not feel good and feels muggy as it has less vapor and more water moisture.

The pressurized type based on every room I have ever tested has more drippiness from the ceiling. This is another reason why getting the right size generator helps so the room does not get to 100% steam and then the steam clumps into moisture since there is no where for the extra steam to go. With dry steam, there is less to worry about since there is less moisture to start with.

People ask me all the time what is wet steam and what is dry steam. Imagine pouring water on a rock sauna. That is super dry steam. Imagine boiling a large pot of water for some pasta. That steam is super wet. The latest steam generators allow just enough water to enter the boiling chamber to become steam and it is digitally controlled. This type is the latest type that has the 3 degree variance.

​3. How to get the driest steam.
Having a non pressurized open tank is the most important thing I look for if I want dry steam but to take it to the next level it can be very expensive. The best selling size is the 9kw and 10.5kw for most homes. 90% of all people coming to my site buy this size.

Comparing two generators that have the same wattage. This is how I tell the difference.
Most steam generators have 2 to 3 two foot heaters curled up in the boiler. A 9 kw steam generator can have 3 heaters that are 3000 watts each or it can have two 4500 watt heaters and or it can have one 9000 kw heater.
The generators that have more heaters with more surface area and less wattage per heater should make the driest heat.
For those that want to experience the driest steam I have found in all the steam generators I've reviewed are the ones that have 11 foot heaters curled up instead of the 2 foot heaters. The average 10.5 kw generator has 2 two foot heaters. The top end models have three 11 foot heaters. The driest steam generator at the lowest size comes in 9kw if someone wants to get three 11 foot heaters and have an open boiler.

Dryness ratio: This is the biggest concern I get. Those who want a steam generator that gets really hot then cools down then gets hot then cools down may want the pressurized boiler types. These are the original type. Many people do not like having to wait for the steam to kick back on each time and want a more continuous steam. This is when many people like the Thermasol or the Steamcore. These 2 are very different. One brand has dual boilers, a large main one and a smaller one so their is continuous steam. This is a pressurized type too kinda like a pressure cooker in the kitchen. The Steamcore is different than the Mr. Steam and the Thermasol as it is an open tank. It lets just enough water to come in when there is a 3 degree variance. This makes the driest steam and is similar to what people can experience in a sweat lodge.

​Example of wet steam: Boiling a pot of water for pasta and breathing in the steam coming off. That is steam that is very damp and not 100% vapor

Dry steam: Taking that same pot and pouring all the water out and heating it up. If the pot is dry and it is put into the sink and you put just a little water into it, you can see the water evaporate in front of your eyes. That is dry steam, 100% evaporated. Pressurized tanks similar to a pressure cooker dump all the steam at once. Open tanks are the type that give the most vapor and less moisture.

For those who don't quite understand wet steam, if I go in a steam room with an open steam tank that has the 11 foot heaters and I take a water bottle and start spraying, it will eventually become humid and the steam will become wet steam and clump together. When a generator dumps the steam before it is all vaporized when the steam room temperature goes down, the boiled steam is not ready to release but releases anyway since the sensor told it to. These steam rooms are the drippy type where their is way too much dripping from the ceiling and the room is hot but with less steam vapor.

Note: There is nothing wrong with the single boiler type like the Mr. Steam or the double boiler continuous type like Thermasol. The latest generation open tank types with digital timed water is the only type I found to give consistent dry steam the entire time. Those who buy the first two types that have the need to splash water on the sensor will only trip the sensor and let out the steam before it is ready to go out and all this does is give out even wetter steam that has not evaporated yet into vapor.

Drippy steam - this is another complaint. The wet steam types usually cut of the steam and there is a long enough window for all the steam to go away. The open tank gives the closest to the 100% vapor and the low drippiness is due to the low latent heat index rating of that generator. If the room heats up too quick it has a higher rating. If there is less moisture and more vapor the room can hold more steam.

Surface area of heaters: It is out of most people’s budget but the steam generators that have larger heating elements have more surface area. Most models have two 2 1/2 foot heaters and some have three 11-foot heaters. A 9kw generator that has 3 3000W heaters that are 11 foot long versus the same 9kw model that has 2 4500W heaters that are only 2 foot in length close the gap between nearly 100% dry and the next noticeable difference. This is comparing only the open tank types.
We are not allowed to advertise discount prices.

If you already know the kilowatt size and model of the Thermasol steam generator please call me. I doubt that my prices will be higher than others who have more advertising expenses and overhead than me. Also you can always verify the serial number of the machine you are getting to confirm you are buying from an authorized dealer.

Give me a chance to give you a great deal on any brands that I promote.
Thermasol VS Saunacore VS MR. Steam "in a nutshell"
Before deciding on a Mr. Steam, Steamcore, or Thermasol make sure you really know the differences.
The Mr. Steam has a shorter duty cycle while Thermasol and Steamcore have a constant steam that you don’t have to wait with no steam. The vapor in the Steamcore is the driest and most dense while the old style single tank pressure cooker types let out steam with more moisture that is not evaporated into steam yet. The steam cloud on a Steamcore or Thermasol lingers and doesn’t drop to the floor as quick and there is way less drippiness. The latent heat index is lower with less moisture in the steam so the steam stays in the air and doesn’t stick to the walls and ceiling. If someone has a ceiling over 7 foot tall, I would only go with a drier steam so the steam doesn’t rise to the ceiling from the high latent heat. Lag time on the Mr. Steam is much higher since it only has one tank.

Another thing is the noise. Steamcore doesn’t work like the pressure cooker type so it is very quiet. With high pressure steam generators you may need to buy a drip pan and empty it out all the time. Not with Steamcore. Those who don’t want to pay to replace heating elements and pay for a new boiling tank in the future may want to have a surgical steel tank and heating elements. More expensive up front but a lot less maintenance. With surgical steel you don’t need to buy a gallon of solution to clean the tank every 90 sessions if your water is hard.

For those that want the short duty cycle type, Mr. Steam is the best single tank generator. Comparing it to Elite steam (Steamist), which is my 2nd best single tank. Steamcore and Thermasol have the 2 best steam qualities I have tested of all the generators so far. (Many people will find SteamSpa (made in China). I have many stories I can tell you about experiences with that brand). As far as Thermasol and Steamcore, Steamcore has a denser steam and has the least maintenance. It is more expensive than all the others but for those that do just one session with a Steamcore it is hard to go back to any other steam. I discount Steamcore to make it closer to the prices of Mr. Steam and Thermasol.

21. How tall will your ceiling be in the steam room?
22. How long do you want to stay in before your core heats up too much before you want to get out?
23. Do you prefer a wetter or dryer steam?
If the steam is too wet and the latent heat is too high it will be harder to enjoy the steam longer. Heart rate will go up to fast.
Steam that is from low pressure boiling tanks are the drippiest. Drier steam is more gassy and less drippy.
27. Are you installing a marine grade waterproof fan for a more uniform steam?
There is really needed if the ceiling is over 7 feet. 12 inches makes a huge differences where the fan brings that steam down from over your head.

25. Do you like your steam so dense that you can't even see the person in front of you?
Notice for people looking at a 6kw or 9kw Thermasol: 
I urge people to read below. Many people think they know what size they want. Most sizing charts are generic. On the below example, many people call in and say they need a 12kw and they actually need a 9kw. Those looking at a 6kw size generator are the people that get the wrong size the most. On the Thermasol, their 6kw is for up to 84 cubic feet. The Steamcore, for example, their 6kw can handle up to a 175 cubic foot room. I urge people to take the sizing chart quiz I made that will help me pick out the right size based on your answers. Please take this quiz AFTER YOU TAKE THE MAIN STEAM QUIZ ON THE BOTTOM OF THIS PAGE. The sizing quiz is at the top of the page.
One sizing does not fit all brands. So, the Thermasol 6kw model can work up to 84 cubic feet. MR. STEAM can handle up to 110 to 150 cubic feet (150 assuming when we tested it at 7 foot. If 8 foot then stay with 110 cubic feet. The Steamcore handles up to 175 cubic feet. 
The Steamcore non pressure cooker type generator needs a 12kw generator for 525 cubic feet. If someone uses this information and wants dry steam with low condensate and chooses a 12kw Thermasol for 525 cubic feet, it can be the reason for a return since it is the wrong size. Please take the sizing quiz.

For steam rooms that have a generator that makes too wet of steam (high moisture in the steam, high condensate), this ventilator helps get rid of the moisture caused by Brownian motion on the ceiling.
If getting a water pressure reducer make sure you get the type that does not have a cartridge and does not have plastic internals.
All brass and all internals are separate instead of being in a cartridge. The best go down to 10psi without plastic mounts and cartridges. Most plumbers don't do a flush during the first installation that can ruin the pressure reducer from day one. 
This is the water pressure reducer that I urge people to look into if using a steam generator with high water pressure. The good ones cost around 500 to 700 dollars. With certain models the warranty can be voided if not using a water pressure reducer and the steam generator is damaged. This will not be covered under the warranty (fine print that most people don't even read on life time warranties).
