Why fit an air source heat Pump ?
Oil & Gas boilers use 100% carbon fuel and are a maximum of 95% efficient. Heat pumps use electricity to capture heat from outside with over 400% efficiency.
Most days electricity is between 40 - 70% carbon neural because of wind and solar power.
A gas or oil boiler will produce less than 1kW of heat energy for every kW of gas/oil consumed. A heat pump on the other hand harvests renewable energy from the outdoor air so will produce 3 or more kW of heat energy for every kW of electricity consumed.
Heat pumps can be cheaper to run than boilers, no emissions, extremely quiet, in fact as quiet as a library !
The controls are simple to use, you can see and set the temperature for each room, see your hot water temperature via a simple touch screen or tablet.
