Air source heat pumps can offer cost savings against most forms of heating in both domestic and commercial settings. When combined with the Government’s Renewable Heat Incentive (RHI) returns can be well in excess of bank savings rates.
Domestic Savings from Air Source Heat Pumps
An Eco Air Boiler can cut your heating bills by up to 65%. In the most favourable conditions this could offer a payback of as little as 3 years on a new build against an alternative heating system. As an MCS accredited installer Global Energy Systems will provide a tailored savings estimate for you property. This estimate will lay out the potential savings based on the location of your property, your alternative fuel type and energy prices at the time. These savings estimates will be compliant with MCS guidelines and the RECC scheme.
Our case studies provide an idea of the savings that some of our customers are enjoying. The running costs are taken from their Eco Link energy portal which shows the running of the heat pump over the year.
How you use your heating and how you design your heating system will have a major effect on your savings. Global Energy Systems will help you to programme and manage your heating with your new air source heat pump. We can also arrange for a Green Deal Assessment to identify any qualifying measures of insulation that you may wish to consider.
The Micogeneration Certification Scheme (MCS) is the accreditation scheme for the domestic renewable energy sector. An MCS certificate for a heat pump installation should ensure access to government grants and subsidies.
As an MCS certified installer and manufacturer Global Energy Systems can offer full MCS support.
Domestic Renewable Heat Incentive (RHI)
The Renewable Heat Incentive (RHI) is the government’s flagship policy in heating. It offers subsidies for the installation and use of renewable heat sources such as air source heat pumps.
The tariff rate for an air source heat pump is 10.18p for each kWh of renewable heat generated. In most cases this will be based upon a deemed, or estimated, assessment of the heat a home uses from an Energy Performance Certificate, but metering will be used in some cases. Domestic RHI subsidy payments are publicly funded. Therefore, BEIS introduced heat demand limits which came into force on 20 September 2017, to help ensure that subsidies represent good value for money in order to protect the public purse. Heat demand limits are set for air source heat pumps at 20,000 kWh. You can still apply if your annual heat demand on your Energy Performance Certificate (EPC) is higher than the heat demand limit, however your RHI payments will be capped in line with these limits.
To qualify for the Domestic RHI a property must be registered as a single dwelling and have its own dedicated heat pump. Properties with two council tax bills and a shared heating system are covered by the Non-Domestic Renewable Heat Incentive.
In most cases the RHI will be paid quarterly based on a “deemed” calculation using the efficiency of the radiator/underfloor heating system and the estimated heat use of the property from an EPC. Where a property has a bivalent heating system, using a heat pump and a combustion boiler, or is occupied for less than 6 months of the year, meters will be required to demonstrate the proportion of the deemed figure that the heat pump is providing.
The Domestic RHI pays for 7 years, offering a significant contribution towards the costs of installing an air source heat pump system.
Commercial Savings from Air Source Heat Pumps
Many commercial heat uses are suitable for air source heat pumps. In the commercial setting, heat pumps can be used as both full and partial solutions. Through the use of integrated controls, heat pumps can work alongside boilers to offer an optimum balance of capital outlay and run costs. The payments available through the Non-Domestic Renewable Heat Incentive can make this a very effective investment.
Many commercial heat users have longer seasons than domestic systems. This allows them to benefit from the increased savings air source heat pumps can offer in the warmer months. Swimming pools, hotels, care homes, water pre-heat and agricultural processes can all benefit from this.
Sites with access to mains gas, or faced with large connection charges, can also benefit from air source heat pumps. Where direct electric heating is the only alternative air source heat pumps can offer huge cost and carbon savings. If you are off gas, heat pumps could be your ideal solution.
The Non-Domestic Renewable Heat Incentive is available to nearly all commercial heat uses, with the exception of outdoor heaters or pools and temporary structures. The scheme pays 2.61p/kWh of heat used from the heat pump and paid of metered output. The scheme lasts for 20 years and is index linked.
Where inefficient, end of life systems are being compared to RHI funded heat pumps payback on investments can be as little as 3 years.
There are small pockets of money available from other sources for heat pump projects. The farming industry has some available for instance. If your project is for a community resource, such as a village hall the Landfill Communities Fund may be able to help (http://www.entrust.org.uk/environmental-bodies/eb-search ).
