What is the difference between a boiler system and an electric system? How do I decide which one to use?
Boiler systems, commonly referred to as hydronic systems use a dedicated boiler to produce hot water that then passes through a heat exchanger to heat a glycol mix. (glycol is similar to the antifreeze in your car). The glycol is pumped continuously through a series of pipes or tubes under the surface to maintain a temperature high enough to melt snow and ice. The system runs all winter, even when there is no snow, drifting or freezing rain occurring. It must be kept running to make sure that sub zero glycol does not enter the heat exchanger which will crack with the temperature difference of sub zero glycol and high temperature hot water. The system also includes make up water valves, air eliminators, return and leaving liquid temperature controls, manifolds, multiple pumps, etc. glycol should be tested frequently and changed regularly to make sure it is of a good quality so it does not freeze. You, as a homeowner will be responsible for making sure the glycol is disposed of in an env
