With a hydronic system almost endless hot water can be supplied from the boiler, all year round with an indirect fired water heater or a tankless heater. Indirect water heaters do not have a separate fuel supply, such as a gas pilot light, but rather use the hot water generated by a boiler to heat domestic water. Our tank-within-a-tank design allows hot water produced by the boiler to circulate in a steel outer tank which wraps around an inner stainless steel tank, radiating heat through the walls of the inner tank, keeping a steady supply of hot water on hand.
A hydronic system will ordinarily serve 25 years or more, both because of the material used and the minimum number of moving parts. A warm air furnace, which has far more moving parts and requires frequent changing of air filters, will normally last 10 to 15 years, with major repair a possibility at some point before maximum life is reached.
