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-fired 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.
If there are space constraints, a tankless heater, which is simply a coil through which tap water is circulated, can be installed in your boiler. In both cases, during the summer months when the heat in your home is shut off, the boiler operates at a low fuel level, about the same as an ordinary water heater.
A hydronic heating system also permits the installation of a snow-melt system. Tubing may be installed under sidewalks and driveways. Hot water is circulated through them, and snow is melted as fast as it falls. Hydronic systems can also be easily adaptable to heating swimming pools, greenhouses and separate garages.
Hydronic Heating Systems are Cleaner
Heating systems, in themselves, do not create dirt. Dirt results from cooking, air infiltration and tracking it in from the outside. However, warm air heating systems create turbulence because they operate with a blower. Rapid agitation of the air causes dirt particles to be deposited on walls, furnishings, curtains and drapes. Even filters cannot effectively control this situation, inasmuch as they trap only larger particles of dirt.
With a hydronic system, heat is gently circulated uniformly and without sudden on-and-off cycles that create turbulence. This fact, plus the fact that a hydronic system operates at relatively low temperatures, allows you to keep a cleaner home.
Hydronic Systems are Quiet
With a warm air system, heated air is conducted through sheet metal ducts that expand and contract as the air temperature rises and falls. This results in noise from the heating ducts. Another major noise factor with a warm air system is the sound of the blower when the furnace is operating. Hydronic systems are generally quieter than warm air furnaces.
Hydronic Systems are More Durable
A cast-iron hydronic system will ordinarily serve 25 years or more, both because of the material used and the small 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.
