Energy Management - Optimising Air Source Heat Pumps for Domestic Hot Water

Just when you have made the right choice of green energy heat pump and feel comfortable in the knowledge that you have done your bit, I am going to tell you that there are further improvements to be made. Introduce Whzan, and your energy management system is optimised. How?

Air source heat pumps collect heat from the outside air. When it's warm these new hot water generators can collect from the outside up to 5-6 times their own running energy and move it into domestic hot water. The ratio of useful energy collected to energy consumed is termed the coefficient of performance (COP).

However, with this prolonged cold spell, air source heat pumps may be running with a COP as low as 2 which means that you have to supply a lot more electricity than normal to heat the hot water tank. What can be done?

Add an outside temperature sensor and Whzan to monitor and control it to build up your heat store when the air is warmest. Just a few degrees centigrade difference can make a considerable difference to your heat pump running costs and your energy bill.

When it's done, you can sit back to watch and adjust your system from the comfort of your web browser. That sounds nice and easy energy management to me.

Contact the Whzan team and find out more about energy management and Whzan.
