Radiant floor heating can be an economical and convenient way of uniformly distributing heat through out your home. When it comes to deciding on the best water heater for radiant floor heat, a highly-efficient tankless water heater is going to be your best option, for a number of reasons.
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. Adding to this, because of heat exchangers and temperature sensors working alongside the tankless heater’s computer modulator, water will never be heated too much or too little. Because a standard water heater can’t alter its flame intensity or instantly provide hot water, there’s no way for it to accomplish what a tankless water heater can do so effectively.
What’s more, the whole process of a well-designed radiant floor heating system can be managed with a home’s standard thermostat and can permanently cut energy costs. For more information regarding our top water heater picks, check out the comparison chart below as well as the reviews that follow.
