Abstract
A heater system comprising a main water discharge and main water return adapted for connection to space or domestic hot water heating means, a main water heater operative for heating water flow therethrough and connected in series with a main pump, and a control system adapted for connection to the space or domestic water heating means and operative to actuate the pump and cause the heater to heat water passing therethrough in response to a signal from a thermostatic sensor in the space or domestic water heating means.
Claims13
A heater system adapted for connection to both space and domestic water heating systems comprising:
- a main water discharge and main water return:
- a main water heater having a water inlet and a water outlet and operative for heating water flowing therethrough;
- a main pump connected in series with said main heater between said discharge and return;
- a bypass conduit connected across said main pump and main heater in parallel with said main discharge and return;
- a balance valve mounted in said bypass conduit;
- and,
- a control system adapted for connection to each of said space and domestic water heating systems and operative to activate the main pump and cause the main heater to heat water flowing therethrough and to cause heated water to flow through a respective one of said space and domestic water heating systems when the temperature sensed by a temperature sensing control in said respective one is below a respective predetermined temperature level,
- said balance valve being effective to maintain a dummy load thereacross.
A heater system comprising:
- a main water discharge and a main water return adapted for connection to space or domestic water heating means;
- a main water heater having a water inlet and a water outlet and responsive to flow of water therethrough to ignite said heater and heat water flowing therethrough;
- a bypass conduit connected in parallel with said main heater;
- a main pump serially connected with said main water heater and said bypass conduit;
- valving for causing water from said pump to flow through a selected one of said main water heater and said bypass conduit;
- a control system adapted for connection to said space or domestic water heating means and operative to activate said main pump and cause water to flow through said main heater whereby said heater heats water flowing therethrough in response to a temperature sensing control in said space or domestic water heating means;
- and,
- a first safety control including a first sensor arranged to sense the temperature of water in one of said return and said discharger and means responsive to said first sensor and operatively connected to said valving for causing water flowing from said return to said discharge to flow through said bypass conduit rather than said main heater and thus not to be heated by said main heater when the sensed temperature of said water is above a first predetermined level.
