Abstract
A heating system comprising a fuel burner in co-operation with a primary heat exchanger, a reservoir for storing warmed water in, and a blending valve, and a controller wherein in use a user can signal to the controller to warm the water in the water store using a heater or by the primary heat exchanger, and when hot water is required water is removed from the water store and mixed with water from a cold main prior to being or after the water from the cold main has been admitted to a further heat exchanger for heating the water.
Claims10
A heating system comprising:
- a boiler including a fuel burner in co-operation with a primary heat exchanger,
- a reservoir for storing water,
- a further heat exchanger arranged to receive heated fluid from the primary heat exchanger for heating the water to an output temperature,
- a blending valve having a first inlet for receiving water from a cold main, a second inlet for receiving water from the reservoir or for receiving water that has passed through a reservoir heat exchanger within the reservoir, and an outlet for supplying water to an inlet of the further heat exchanger,
- and a controller having a user interface,
- the controller signaling the water in the reservoir to be heated using the boiler to a temperature greater than the output temperature, removing water from the reservoir, or warming water by the reservoir heat exchanger, mixing the water with water from a cold main by the blending valve to obtain water at a blended target temperature lower than the required output temperature, and admitting the water at the blended temperature to the further heat exchanger to heat the water to the required output temperature.
