Air Source Heat Pump Installation

A simple way to describe how a heat pump works is that it does what an air conditioning unit in cooling mode does, but in reverse! When in cooling mode, an air conditioning unit will extract the heat from indoors and release that heat outdoors. A heat pump will take heat from outdoors and release it indoors. Not a lot of people are aware, but most new air conditioning systems are fitted with a heat pump already, so you can use the air conditioning in the summer to keep you cool and benefit from the heat pump in the winter to keep you warm.

There is another form of heat pump, a heat pump boiler system which is proving a lot more popular in the residential market. A heat pump boiler is an advanced heating system for the home which will supply hot water for washing and central heating, just like a traditional boiler – but it’s different from traditional boilers in a number of important ways. It’s more energy efficient and could reduce energy bills by at least a third. It also produces half the CO2 of a traditional boiler, which helps to reduce any impact on the environment.

By transforming the energy found naturally in outdoor air and using that to help provide cost effective heating, we’ve already established the efficiency of a heat pump and the fact that it ‘upgrades’ energy. Take that one step further and consider using a heat pump powered by electricity from a renewable energy source such as wind, biomass, solar or tidal and you could have a heating system that is zero carbon rated!

With conventional boilers, 1kW of input energy provides less than 1kW of output energy or heat. With heat pumps, every 1kW of input energy is converted into an average of 3.6kW of output energy or heat, making it more than three times as efficient as conventional boilers and a natural choice for low cost heating and hot water.

The Co-efficient of Performance (COP) of a heat pump is the ratio of the heat delivered, divided by the power consumed. The modern heat pump technology used in this example has the seasonal COP rating of 3.6.

Another advantage with heat pumps is their ease of installation and design flexibility. A perfect answer to those wide areas of the UK which are not perhaps on, or likely to be on the National Gas Grid. This negates the need to consider the more costly options of electricity or oil and removes the need to negotiate the enormous expense and disruption of extending the National Gas Grid. Whatever the location, simply install a heat pump and enjoy efficient, effective heating and hot water at a fraction of the alternative cost.

Heat pump technology is tried and tested. It has been widely used in other European countries for decades and represents a new era in the provision of heating and hot water for homes in the UK.
