Frequently Asked Questions

What Exactly Is an Air Source Heat Pump?

An air source heat pump is a device that is able to absorb heat from the outside air, and then deliver this heat within the interior of buildings, is called an air source heat pump. There are actually a couple of types of air source heating system technology available today. First of all, there are…

Are Air Source Heat Pumps Efficient?

If you have an electrically heated home in the UK, if these units are installed, based upon figures that were obtained from the Energy Saving Trust, these air source heat pumps could actually help save £870 every single year on heating bills as well as prevent the release of 6 tonnes of carbon dioxide throughout…

How Do Air Source Heat Pumps Actually Work?

An air source heat pump is a device that has three primary parts: There is the evaporator coil which is able to absorb heat from the outside air; the compressor pumps a type of refrigerant through the heat pump, then compresses the gaseous refrigerant to the proper temperature for heat distribution; and, the heat exchanger…

Can Air Source Heat Pumps Work in a Residential Home?

Here are a few conditions to consider before using an air source heat pump in this capacity: First of all, you will need on an external wall which is going to be outside of your house for an installer to place the evaporator coil; because it will be at a lower temperature in comparison to…

Do you need back up heating for additional water or space heating?

This will really depend upon your heating needs in comparison to the size of the system that you design and install; and, Is your home currently being completed? If this is the case, it will be much cheaper to install an air source heat pump in North Yorkshire, along with underfloor heating systems, during the…

How is a heat Pump installed and how long does it take?

A Heat Pump is installed by first removing any existing cylinder and boiler. A typical installation takes around 3-4 days and involves removing the existing cylinder and boiler.

How long will a heat pump last?

The average lifespan of a Heat Pump is the same as a modern boiler, around 15 years. Annual maintenance can significantly improve the life expectancy of your system.

What maintenance does a heat pump need?

Very similar to a normal boiler. It is advisable to have an annual service in order to keep the warranty valid and ensure that the unit is working as efficiently as possible.

Does a heat pump work 24hrs a day?

A Heat Pump can provide heating and hot water anytime, day or night, just like a boiler.

Can a heat pump be programmed?

Yes, you can set the Heat Pump to heat your house to a desired temperature for specific times and dates.

Can I increase the heating of a heat pump?

Heat Pumps operate most effectively when they run at a constant temperature. The radiators or underfloor heating is sized to take into consideration the specific type of heat, ensuring that the rooms get up to temperature quickly.

Is a heat pump noisy?

No, the modern Heat Pumps are often quieter than boilers and many other appliances we use in our everyday life.

Can a Heat pump work with standard radiators?

A Heat Pump runs at lower flow temperatures than a traditional fossil fuel system, which results in greater efficiencies. In most cases your existing pipework will be adequate, but we might need to upgrade the output of the radiators. In many older properties, the existing radiators are single panel and we typically upgrade these to…

Will a heat pump work in winter?

Air Source Heat Pumps have the capability to remain efficient even in extreme cold; they continue to function down to -20°C. As average winter temperatures in England are around 5°C, there should never be a problem. This is a very popular system in Scandinavian countries where the temperature is considerably lower for longer periods than…

How do air source heat pumps work?

An air source heat pump absorbs heat from the air outside into a fluid. This is fed through a compressor to increase its temperature, and transferred to the indoor heating and hot water distribution network. Essentially, air source heat pumps work like a refrigerator in reverse. The outside fan unit is usually positioned on an…

How much do air source heat pumps cost to install?

Air source heat pump installations usually cost between £7,500 and £12,500, depending on the size and power of the heat pump, how much hot water storage you require and whether you want the heat pump to have additional features, such as remote web-connected control.

How much space does a heat pump need?

Heat pumps require a bit more space than a traditional wall-hung boiler system. The hot water cylinder is often located next to the system, rather than elsewhere in an airing cupboard. It’s important to plan a dedicated area (plant room) for the equipment. Possible solutions for a plant room are utility rooms, garages, basements, or…

What is the running cost of a heat pump?

Running costs depend on the size of the property and system. The typical UK home requires about 12,000 kW of heat annually. An air source heat pump may create 3 kW of heat for each 1 kW of electricity it consumes. As a result, it will use 4,000 kW to fulfil the demand. As a…

How efficient is an air source heat pump?

Air source heat pumps are between 200% and 400% efficient. This means they produce 2-4 times the amount of heat compared to the energy they use. This might change slightly during colder months, but the heat pump will still be able to power heating and hot water efficiently. For more information about efficiency variations, get…

Can a heat pump be installed in an old house?

Yes, provided you have a suitable heat distribution system installed. In order to qualify for the RHI scheme, you must have an energy efficient building. Therefore, you may need to complete upgrades on loft and cavity wall insulation to meet regulations. Read the Ofgem information for more guidance on installing an air source heat pump…

How long will an Air source heat pump work for?

Typically, these systems last for 15-20 years. However, they have been known to work for longer. With annual servicing and good care, an air source heat pump is an investment that continues to deliver returns over decades.

Does an Air source heat pump need planning permission?

Air source heat pumps don’t usually need planning permission. They are considered in England, Wales, and Scotland to be a permitted development. However, this changes if the property is listed, or if the property is in a protected area. It doesn’t mean that it’s impossible, but you will need to check with the local authorities…

Will an air source heat pump work in winter?

Of course, yes. Air source heat pumps can still deliver heat to your home when outdoor temperatures are as low as minus 15-20 degrees celsius. There might be some slight variation in efficiency and the air source heat pump will need to work harder, but they are designed to work in all seasons throughout the…
