Looking for a water heater that will provide your home with radiant floor heat? While it can be expensive to add whole-home radiant floor heating, adding a new water heater can be much more cost effective, and just as efficient.
The water heaters listed here were among consumers’ top choices when it came to adding radiant heat to the home:
Top LPG Gas Water Heater
The gasFlex Tankless Vent-free LPG Water Heater is gas, and consumers say it provides plenty of hot water. The gasFlex does not require electricity to run, so it can be ‘off the grid’.
It does have an electronic mode, however, as well as a safety backup. This is a pure copper heat exchanger that provides you with radiant floor heat.
Consumers also love that this tankless water heater uses vent-free technology, so you don’t need a flue. They also note that it is very compact, and will fit in any area of any home (it is just 11.5″ by 6″ by 16″).
Reviewers also rave about the design, saying it is sleek and very unique. The gasFlex comes with a lifetime warranty, and consumers say that gasFlex has excellent customer service.
Best Solar Water Heater to Buy
The Duda Solar Stainless Steel Solar Water Heater is another top choice when it comes to providing your home with radiant floor heat.
This solar water heater comes in a variety of sizes; make sure to figure out your water needs before you purchase. Reviewers say it gives you more heat, even in colder climates.
The Duda Solar Water Heater has a rating of OG-100 by the Solar Rating and Certification Corporation which means that it is eligible for a tax rebate, which reviewers appreciated.
With the Duda, once the water is heated, it is stored in the tank. This means it will lose less heat. If you place the heater in a more centralized location, near where everyone needs hot water, the water will be delivered quickly, and you won’t have to wait for hot water.
Reviewers say that this is a good, quality system to purchase if you want a ‘greener’ way to provide hot water, and radiant heat, to your home.
Top Solar Water Heater under $2000
Stiebel Eltron SBB300 S is another reputable name in home heating. Their solar water heater with a single heat exchanger is a great way to heat your water and provide radiant floor heating to your home.
This model provides minimal standby loss of heat because it has three inches of foam insulation. It holds just over 80 gallons of water, and it uses a single heat exchanger which is indirectly fired. Reviewers note that it does have to be connected to some other form of external backup heater if you want to use its solar aspect.
Reviewers say the hot water stays hot, and there is very little maintenance involved with this model.
Best Electric Tankless Water Heater
Owners of the iHeat 2.3 GPM Tankless Water Heater say that the ‘hot water just keeps on coming!’ It seems that the iHeat heats water quickly, and it never seems to run out.
The iHeat is an energy saver, and reviewers say that they notice this on their electric bills. It is also lead free certified for your safety.
Some reviewers say that they use this heater on their boats. It is a smaller unit, perfect for small houses, apartments or condos. This compact unit uses just 220 volts of electricity and weighs just over 8 pounds. The unit heats water to 105 degrees, which consumers say is just right.
They also note that this is a solidly built unit. Note that the iHeat comes in a number of sizes and models, so find the one that is perfect for your home or boat!
