Abstract
A recirculating hot water system comprises a boiler for heating a continuous supply of hot water, a recirculating water line comprising a supply line connected to an outlet of the boiler for conveying water from the boiler to at least one use station and a return line for returning water not consumed at the station to the boiler, a circulating pump in the return line for continuously circulating water in the water line, a by-pass circuit for by-passing the recirculating line connected at an outlet of the pump and an inlet to the pump, and a by-pass valve in the recirculating line at the by-pass line for directing water at a predetermined temperature through the by-pass line.
Claims16
A recirculating hot water system comprising:
- a water heater for heating a continuous supply of hot water;
- a recirculating water line comprising a supply line connected to an outlet of said heater for conveying water from said heater to at least one use station and a return line for returning water not consumed at said station to said heater;
- a circulating pump in said return line for continuously circulating water in said water line;
- a by-pass circuit for by-passing said recirculating line connected at an outlet of said pump and an inlet to said pump;
- and
- a by-pass valve in said recirculating line at said by-pass line for directing water at a predetermined temperature through said by-pass line.
A continuously circulating hot water system comprising:
- a hot water heater for producing a continuous supply of hot water, said heater having a supply inlet, a return inlet and an outlet;
- a circulating water line system comprising a supply line connected to said outlet for conveying water to a plurality of use sites and a return line for returning water not consumed to said return inlet of said heater;
- a circulating pump having an inlet and an outlet, said pump disposed in said return line for continuously circulating water in said water line system;
- and
- a by-pass circuit including a temperature responsive valve in said return line between said outlet of said pump and return inlet of said heater and a recirculating line connected at a by-pass port of said valve and said inlet to said pump for directing water at a predetermined temperature through said by-pass line.
