Hydronic - Hot water systems
This is the most popular and cost effective way to heat an entire house. Hydronic systems circulate water from your water heater through loops of 1/2-inch polyethylene tubing (as shown in the picture). These flexible tubes can be installed through a variety of ways in your home:
- on top of the subfloor in grooved panels or snap-in grids
- clipped into aluminum strips on the underside of the floor
- embedded in poured concrete (the most common)
Once the system is in place, you can cover it with most types of finished flooring if you choose, including hardwood and tile.
