Can you use an electric tankless water heater for radiant heat?
Though they are sold primarily for domestic hot water, tankless heaters are actually well-suited for radiant heating, which operates at low temperatures compared with, for example, hot-water baseboard. So using the unit for radiant heating generally has little or no effect on the sizing calculation.
How long does radiant heating last?
Radiant floor heating systems are made using high tech materials and can have a lifespan of up to 100 years. If well maintained, these systems can beat the lifespan of conventional HVAC systems. However, you will need to replace the mechanical parts of the system over time.
Is it expensive to run a radiant heating system?
Like any type of electric heat, radiant panels can be expensive to operate, but they can provide supplemental heating in some rooms or can provide heat to a home addition when extending the conventional heating system is impractical.
Are there any downsides to radiant floor heating?
The down side is two heat sources. All water heaters waste heat energy, even when the burner is off and the unit is sitting idle between heating cycles. Granted, the unit dedicated to heating the floor only wastes heat during the winter months. But standby losses for six months out of every year can add up. The other consideration is efficiency.
What does it mean when your house has radiant heating?
Radiant heating is the effect you feel when you can feel the warmth of a hot stovetop element from across the room. When radiant heating is located in the floor, it is often called radiant floor heating or simply floor heating.
What should I put in my closed radiant heating system?
Air is the WORST thing that can happen to any (Hydronic) Radiant heating system. Follow this link, for information on filling and purging your Closed Radiant heating system. We recommend Propylene Glycol (not automotive, Ethylene Glycol) antifreeze.

Why is my radiant floor heating not working?
If thermostat is setup properly and activates the heating system as it’s supposed to, underlying issue may often be with the flooring itself. Insulation is critical for any type of radiant floor heating (RFH) system – electrical or hot water, and its’ job is to ensure that that the heat produced by the system will not sink into the flooring below.
Why are radiant air floors not cost effective?
Air cannot hold large amounts of heat, so radiant air floors are not cost-effective in residential applications, and are seldom installed. Although they can be combined with solar air heating systems, those systems suffer from the obvious drawback of only producing heat in the daytime, when heating loads are generally lower.
