Best Water Heater for Radiant Floor Heat

Here in the greater Fort Wayne and Indianapolis areas, jumping out of bed on a cold winter morning can be a rude awakening, especially if your home has tile or hardwood floors. While your furnace has done a good job of circulating warm air throughout your home, there’s not much it can do to warm up those cold tiles and wood planks. Of course, there is a solution for that particular issue: radiant floor heating


Your friends at Masters Heating & Cooling Inc. offer a complete line of radiant floor heating solutions. Here’s a quick explanation of how radiant floor heating works: a boiler/water heater heats water, then pumps it through a series of tubes installed beneath the flooring of the home. It differs from a forced-air furnace in that it doesn’t heat air. Instead it heats objects and radiates heat from the floor up. While it is not a viable option for all homes, if you are planning to build a new home or do an extensive renovation of an existing home, here are some advantages of investing in radiant floor heating:

  • No ductwork/registers. This eliminates worrying about placing furniture over registers or cleaning the ductwork.
  • No blower/fans. This is about as quiet as it gets when it comes to heating. It also eliminates dirt and other allergens being blown throughout the home.
  • More efficient/longer lifespan. Radiant floor heating is more efficient than a forced-air system, primarily because it does not lose any energy through ductwork. It will also last 30-plus years if well-maintained, while a furnace lifespan runs from 10-15 years in most cases.


The water heater is an integral part of a radiant floor system. Traditionally, this has meant a regular tank heater, but more and more homeowners are turning to tankless heaters for their radiant floor systems. A big reason for this is the efficiency of tankless systems. With a regular tank heater, there is more heat energy generated than needed and some energy is always lost at the source. With a tankless heater, only the amount of heat energy needed to heat the water is used and it all goes directly into the water. Here is the tankless model that operates on gas that we recommend:

  • Navien. This product line includes water heaters for residential hot water, combi boilers that can supply hot water for the house AND for your radiant heating system, and stand-alone boilers.
