The Ultimate Furnace Guide – Everything You Need to Know

A boiler, or a hydronic heating system, provides heating by using a fuel source to heat a fluid (such as water or glycol) that is pumped through your hydronic heating system to various devices such as radiators or in-floor heating loops. Boiler heat does not require ductwork and is often be found in older homes. Combi-units
