The benefits of Air Source heat pumps
You can benefit in many ways from fitting an air source heat pump and exactly what you are able to earn or save will be dependent on your circumstances, however you could benefit by over £600 per year.
- Reduce your carbon footprint: Heat pumps can lower your home’s carbon emissions, depending on which fuel you are replacing, because they reduce the fuel that you need to burn for heating.
- Reduce your heating costs: This is especially true if you are currently using conventional electric heating. Heat pumps provide space heating and hot water more efficiently than traditional heating sources, saving you money on your bills.
- No fuel deliveries required: By replacing your oil or solid fuel heating system you are removing the need to have fuel deliveries. All that is required is electricity to power the pump.
- 'Fit and forget’: Heat pumps are often classed as a ‘fit and forget’ technology because they need little maintenance.
Getting paid for producing heat
You will be able make money out of the heat you produce through the Renewable Heat Incentive scheme, details of which will be released in 2013. Learn about the Renewable Heat Incentive and RHPP here.
An example created by the Energy Saving Trust shows that a typical domestic electrical system could earn around:
- £610 per year reduction in current electricity heating bills
- A single Renewable Heat Premium Payment of £850
- A regular payment from the Renewable Heat Incentive – to be confirmed in 2013
What to do next?
- Where in my house should an air source heat pump be installed?
- The bulkiest component of an air source heat pump is the air handling unit, which must be fitted outside. The unit can be fitted on an outside wall, but some designs allow this to be fitted some way away from the home, as far as 20-30 meters. The heat pump needs to be in or on the house and typically this is where the essential components are housed.
- Will an air source heat pump provide enough hot water for heating and hot water?
- If you do not heat your water beyond 55°C and your system has been correctly scaled and fitted for your needs there is no reason why all your domestic hot water requirements shouldn't be provided by the air source heat pump throughout the year. It should be noted that heat pumps produce water at a lower temperature than boiler systems, meaning that you will need larger radiators or an underfloor heating system or the pump to heat your house effectively.
- What properties are not suitable for an air source heat pump installation?
- Air source heat pumps are not suitable for use in houses where the levels of insulation are not known and where the age and type of the heating distribution system (radiators and pipes) is unknown. Because they produce hot water at a lower temperature than conventional boilers they are particularly suited to house with under-floor heating.
- Will I need a new boiler to install an air source heat pump?
- An air source heat pump can provide all your hot water and heating requirements without the need for top-up from a boiler. However, a boiler can be used alongside the pump system as a top up to meet demand in colder weather. This will depend on your current heating system's design.
- How much hot water is produced each day by an air source heat pump?
- This will depend on the make and model of air source heat pump that you're planning to use, but a well chosen pump should be able to meet all of your heating needs. You should aim to get advice from at least one well accredited installer when choosing a model.
