Water Heaters For In Floor Radiant Heat

A pump kicks on and water runs from the water heater and into the floors.

Water heaters for in floor radiant heat. Water heaters can t produce hot enough water typical boiler systems use a design temperature of 180 f or higher which produces scalding hot surface temperatures at cast radiators and convector units and is too hot for radiant floor applications. For starters as tankless water heaters can instantly heat up water they don t have to be constantly running to provide hot water right when it s needed. Traditionally this has meant a regular tank heater but more and more homeowners are turning to tankless heaters for their radiant floor systems. Hydronic radiant floor heating basics the process begins when either a boiler or geothermal system heats water that is pumped through tubing underneath the floor s surface.

As such we rate it with 5 stars out of 5. In all you can expect to pay anywhere from 6 000 to 14 000 to install a hydronic radiant floor heating system. Water heaters are good for radiant floor heating because they maintain a low temperature. When it comes to deciding on the best water heater for radiant floor heat a highly efficient tankless water heater is going to be the ideal option for a number of reasons.

This includes the system itself and the cost for a dedicated water heater or boiler generally 360 to 1 000 for a 50 gallon water heater or approximately 6 000 for a boiler. There are three different ways to install hydronic radiant floor systems. That temperature is safe and comfortable as well as being efficient. This model has the most impressive flow rate it is well made and it comes with all you are going to need.

You really only need a maximum of 120 f for your floor. We ve been doing this longer than anyone with great success. Dual purpose systems a dual purpose system relies on only one water heater to supply both the hot water requirements for the home and the warm water needed for the radiant floor heat. The water heater is an integral part of a radiant floor system.

The heat generated from the hot water will then rise and warm the floor above. A big reason for this is the efficiency of tankless systems. If you can see the numbers on the gauges in the photo the water going out is about 100 degrees and the water coming back is about 80 degrees. It is the safest choice as well.

Water from the floors runs back into the water heater. You will need to be aware of the incoming groundwater temperature as cold water will drop the overall water temperature.
