A hydronic heating system permits the installation of a snow-melt system. Tubing may be installed under sidewalks and driveways. Hot water or anti-freeze is circulated through them, and snow is melted as fast as it falls. Hydronic systems can also be used for heating swimming pools, greenhouses and garages.
Heating systems 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 from Weil-McLain, heat is gently circulated uniformly and without sudden on-and-off cycles that create turbulence. This, plus the fact that a hydronic system operates at relatively low temperatures, allows you to keep a cleaner home.
With a warm air furnace 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 virtually noiseless.
Equipment that Lasts
A cast iron hydronic heating system will ordinarily serve 25 years or more because of the material used and the small number of moving parts. A warm air furnace, which has 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.
