Air Source Heat Pump Installation across Norfolk

Cost Effective Energy for Your Home

Air source heat pumps (also known as ASHPs) are a highly efficient way to heat your property. They differ from GSHPs with their energy source – extracting heat from the ambient air. They also tend to be easier and quicker to install as they don’t require groundwork. Unlike a traditional gas boiler system, they are powered by renewable energy. This means that they do not rely on fossil fuels, reducing harmful emissions within the environment. Running an ASHP is very economical, and can provide you with consistent heating or cooling throughout the year.

Our trusted team will assess your property and work alongside you to design and identify the most suitable position for your new heat pump. Our team are expert air source heat pump installers, supporting you throughout the process and after installation so that you can get the most out of your ASHP.

How do Air Source Heat Pumps Work?

Air source pumps work by initially extracting heat from the ambient air, therefore it is best to situate the unit in an outside location that benefits from a free flow of air. Of course, our experienced engineers will always take the time to ensure your unit is fitted in an optimal position.

How do Air Source Heat Pumps Work?

The ambient air is pulled into the system, whilst refrigerant is circulated through an evaporator. It is then passed through to a compressor, raising the temperature of the refrigerant and turning the liquid refrigerant to gas.

How do Air Source Heat Pumps Work?

The hot gas is then passed through a condenser, this process increases the pressure and therefore increases the temperature further. The hot gas transfers its heat into the cold water already in your heating system which is then fed into your heating or hot water system to heat up your property.

How do Air Source Heat Pumps Work?

Once the heat has been removed the hot gas turns back into a liquid to start the cycle again! The heat can be retained for later use also, so it’s an incredibly efficient process.

Reduce your use of fossil fuels by up to 50%

Having an Air Source Heat Pump installed into your home not only reduces your overall energy bills but offers you a clear step towards cutting your C02 emissions.

ASHPs provide the opportunity to reduce your overall use of fossil fuels and dependency on the grid. In addition, you could receive £7500 off the cost of your installation with the Government’s Boiler upgrade scheme (BUS).

Eco-Friendly

The environmental benefits are huge, an ASHP installation can reduce your carbon footprint by up to 50% meaning that you can make a huge change in the fight against global warming.

Your Interior Space is Retained

As the main unit is based outside, less space within your premises is required. The systems are generally more cost effective when compared to alternative renewable heating systems too.

Efficiency

On a well-designed heating system with under-floor heating and an outside air temperature of 7°C, ASHPs can reach efficiencies of up to 5kW of heat for every 1kW of electricity used. This is known as the COP (ref EN 14511 A7/W35 Viessmann Vitocal 150-A technical data). In comparison, electric storage heaters have a COP of just 1kW of heat to every 1kW of electricity used.

Reliability

Thanks to their simple structure, with no hot burners required, air source systems are very reliable. This reliability is amplified when they are correctly serviced and maintained. Visit our support page for more information.

Frequently Asked Questions

In short, ASHPs work by moving ambient air through an evaporator in the external heat pump unit. The heat from the air is then passed into the refrigerant circulating through the evaporator. A compressor connected to this circuit then raises the pressure of the refrigerant, which in turn raises the temperature. The heat is then transferred into the heating systems water via a condenser providing you with heated water for space or domestic hot water heating.

Air source heat pumps can be used with a variety of heat emitters like under floor heating, radiators, towel rails or convectors.

The air source heat pump is not just for heating up your home either, during the warmer months your heat pump can also remove the heat from your home by reversing the refrigerant cycle, removing heat in the air within your home and releasing it back outside, leaving you with cooler summer months and warmer winter nights.
- Less space is required internally for an Air Source Heat Pump. Although external space is still required, if you find yourself limited to space inside, this could be an ideal solution for you.
- No groundworks or external collector pipework is required, meaning an Air Source Heat Pump are more affordable than a Ground Source Heat pump.
- A cheaper alternative for heating your home and can be even cheaper with access to government grants.
- An ASHP has an excellent life span.
- It can be used for both heating and cooling of the home.
- Great effective use of using natural energy to heat or cool your home.
- Space to install the external can be hard to find on smaller properties.
- The equipment required internally requires more space than most traditional style systems.
The ASHP is much easier to install than the Ground Source Heat Pump as, unlike the GSHP, no digging is required. As a result of this, the installation process is much simpler and often quicker and usually takes no longer than a week if no heat emitter work is required.
Contrary to some misleading information Air Source Heat Pumps can work in any type of home, although as with any heat source the better the property is insulated the lower the running costs will be.

Due to the lower water flow temperature compared to boilers, some radiators may need to be made larger to provide the same amount of heat at these lower temperatures.

Most common properties are ideal for this type of heat pump, however, space must be available for the external unit. If you live within a larger property a single heat pump unit may not be big enough, however more external units can be installed to work as a cascade, however, this will have an overall effect on the costs.
Compared to a gas or electric heating system, an air source heat pump is a renewable alternative to heating your home, lessening your carbon footprint and allowing you to save money on your utility bills.

Unlike gas or oil boilers the electricity used to power the heat pump can be provided by using renewable resources like photovoltaic solar panels (PV) or wind turbines which can be installed to power the system at the customers own property, increasing energy security and helping owners become more self sufficient.
