Endless Hot Water
Reliable hot water can be supplied from the boiler all year round with a Weil-McLain® 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. We use a tank-within-a-tank design that 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 hot water heater.
