Product Description

Thermomate tankless water heater

Endless Hot Water

Thermomate tankless water heater
  • A tankless water heater heats water directly on demand without storing it in a tank. When you turn on a hot water tap, cold water flows through the unit, where it is rapidly heated by either a gas burner, providing a continuous supply of hot water.

  • Size depends on your household’s peak hot water demand. Calculate the total GPM needed for simultaneous fixtures (e.g., 2 showers at 2 GPM each = 4 GPM) and the required temperature rise (desired temp – incoming water temp).

  • It depends on the unit’s flow rate (measured in gallons per minute, or GPM). Larger households may need a high-capacity model or multiple units. For example, a gas-powered unit with 4 GPM can handle 2 showers simultaneously.

  • Yes! ThermoMate tankless water heaters are more energy-efficient, with a UEF >0.81, saving up to 30% on energy annually.

  • Yes, you need to buy a 150 psi pressure relief valve. To vent exhaust gases, you may also need to purchase a 3-inch diameter metal exhaust pipe.

AT 75k btus this water heater has a lot of power for its size. AT the price I would expect more gpms but the btus make up for it.This is a good option for a small single family home, or even better for an rv, skoolie or tiny house trailer. It has more than enough power to handle the demands of a couple of people.In regards to installation and assembly if you are not familiar with working with propane I would probably leave the diy alone. But you can always try and take the necessary precautions, with a fire extinguisher on hand.Until We Meet Again-Off The Grid Ken

Exhaust pipes don't come with the heater. Be sure you order the correct one(s) for your particular situation or use. Mine will be through the wall to outside. You may want your exhaust to go through the roof which requires different sections and fittings. The use of a system to occasionally clean the heater water line is another item you should order separately. I have a 100 gallon propane tank and a automatic tank switch to swap to a different tank if the first one empties out. I will buy a second tank soon.This heater is one of the best available in propane tankless hot water heaters!

Installed this in my garage. The install was easy and the directions clear. I have used this to wash my jeep in hot water and worked great . As a added plus to jave hot water to wash the grease off your hands and clean the garage floor is very convenient. Value for dollar is great . This is efficient and a quality appliance.

Its instant heating function is very convenient. As soon as the water flow is turned on, there is hot water, and the speed is very fast, so there is no need to wait at all. The maximum flow rate can reach 2.93 GPM, so I don’t feel that the water flow is insufficient when I take a shower or cook. Multiple use points can also be easily satisfied, which is especially suitable for situations where multiple people in the family use hot water at the same time. The 75,000 BTU output of this water heater is very strong, which can stably provide efficient hot water, will not cool down due to excessive water flow, and the performance is very stable. Its tankless design also avoids the trouble caused by the water tank, reduces the problem of scale accumulation, and is more hygienic and worry-free to use.

This ThermoMate Propane Tankless Water Heater looks to be well made and is the same size as the tankless water heater I install 8 years ago in my house. I looked at the other tankless water heaters that this company makes and they all seem to have good reviews. I got this as a replacement for when mine breaks down. Nothing lasts forever and it will be nice to have one on hand when it does go out. This is a great value for this item.
