Air Source Heat Pumps extract the heat from energy stored in the air and concentrate it for use in a heating system. They use the same technology found in air conditioning systems using heat exchangers and compressors. They are a very efficient source of energy (approx 300% efficient), and can be installed as the primary heating source, or used in conjunction with an existing boiler system. If you have an Air Source Heat Pump installed by an MCS accredited installer such as EnergyMyWay you will be able to claim cash back through the Governments Renewable Heat Incentive (RHI) scheme.
Air Source Heat Pumps are becoming an increasingly popular way of heating properties and creating hot water. An Air Source Heat Pump consists of an external unit which looks similar to an air conditioning unit and are sited outside of the property. The units come in a brushed steel finish or can be vinyl wrapped or put behind a hit and miss fence to limit the visual impact of the units. The external unit has a fan which draws the air into it, which passes through a compressor and heat exchanger. The heat from the heat exchanger is used to create hot water, which is stored in a buffer tank until it is needed for either heating or hot water.
The Renewable Heat Incentive (RHI) gives property owners financial rewards for installing renewable energy heating including Air Source Heat Pumps. Under the scheme, you will be paid for every unit of heat your Air Source Heat Pump generates as part of the government’s drive towards lowering carbon emissions in the UK.
Renewable Heat Incentive rates for Air Source Heat Pumps
The RHI tariff for Domestic Air Source Heat Pumps has been set at 7.3/kWh, paid to you for a period of 7 years, tax-free and index linked.
Example Financial returns from a DOMESTIC Air Source Heat Pump
This example demonstrates that your combination of bill savings and RHI payments will cover the cost of your Air Source Heat Pump installation over 7 years, after which you continue to enjoy cheaper bills and protection from future energy price hikes.
Who qualifies for Renewable Heat Incentive Payments?
Domestic property owners, landlords and self-builders now qualify for the RHI scheme.
Before accessing the RHI payments, we will need to ensure that you have undertaken a basic level of energy efficiency measures including loft insulation before your property is entitled to the RHI. This is to ensure that the heat you generate from renewable energy is being used most efficiently in your property.
Every property is different which is why we always carry out a free survey of your property before recommending the right renewable energy technology and providing you with detailed pricing and returns.
To find out more about the RHI or to arrange a free survey contact your local EnergyMyWay, or call 0845 371 3181 firstname.lastname@example.org
They take energy from the air using an Air Handling Unit. This box is situated outside and contains a large fan that draws air into the unit, transferring the energy in the air through large heat exchangers. From there, the process is the same as a Ground Source Heat Pump. They work like a fridge by moving energy from one place to another. For example, a bottle of wine brought from your local supermarket is at room temperature. If you put it in your fridge and wait a few hours it will be cold enough to drink. If you touch the back of your fridge during that time you will feel heat. The fridge has taken the low temperature energy out of the wine, compressed it up to a higher temperature and in effect has warmed the kitchen up slightly. By using the same process Heat Pumps remove solar energy stored in either the earth, air of water around your building, compress it to a higher temperature and transfer it into your central heating system and hot water tank.
The system performs down to air temperatures of -20°c which means that they are more than suitable for installations within the UK. Hot water and Heating can be provided 365 days a year. The hot water is produced without the aid of electrical immersions and at 55°c is more than hot enough for baths and showers.
Well designed Air Source Heat Pump Systems can be over four times as energy efficient as the most efficient gas or oil boiler. Instead of burning a fuel and producing the associated emissions they simply move energy that already exists – stored energy in the air generated by the sun. If you compare their performance against solar panels fitted to roofs, ASHP’s can produce over six times more renewable energy.
They hum like a refrigerator, generally they are sited outside out of the way and you won’t notice the slight humming sound. The units we supply have had many years of research and development that has included noise and vibration minimization. We have taken great care in our development programme to ensure that people in the home do not hear the units.
Each Air Source Heat Pump is designed to operate for at least 20 years.
No annual maintenance is required.
Ideally as close to the property as possible, the further away the more heat loss you can experience from the pipes and the less efficiently it will work. Our systems split the space heating and hot water heating so that it delivers the highest efficiency all year round (e.g. you don’t want to be running a large ASHP compressor in the Summer just to deliver hot water). The space heating unit is sited outside so that you have no refrigerant entering the house and no potential for the gas to escape into the property.
The owners of a 1950s detached house are a couple with four young children. They wanted to reduce their electricity and gas bills. EnergyMyWay installed two renewable energy solutions, which work together. Solar PV The roof is south facing and large enough to accommodate 16 solar panels. Kent and Sussex has the largest amount of irradiance in the UK, making it the best location for solar PV performance. A 4 kWp solar PV array using…
Installed in March 2012 Dimplex LA 6 MI inverter, monoblock heat pump and combined hot water cylinder and buffer tank. New build property, connecting heat pump and cylinder into under floor and hot water distribution systems.
Through an existing business contact, Energy My Way (Warwickshire) Ltd were contacted and asked to provide a cost effective solution to complete the installation of air source heat pumps to six partially completed new build dwellings in Cheshire. The project had come to a standstill at the end of 2011 due to the previous developer’s cash-flow issues and the scheme is now being completed by the funding bank. Energy My Way was required to investigate…
Mrs Jones called EnergyMyWay Herefordshire to discuss installing Solar PV on her barn conversion (following a successful advertising campaign we’d run in a local newspaper), and happily we were awarded the contract. The roof of Mrs Jones’s newly constructed barn conversion was tiled with traditional grey Welsh slate, so we discussed at length the options that would best fit aesthetically. Mrs Jones opted for black panels with black frames which complemented her roof perfectly. Careful…
The clients are not on the gas grid and wanted to convert from using oil for their space and water heating to using a renewable energy source and to take advantage of the Renewable Heat Incentive.
