Welcome to your new home, heated by a Grant Air Source Heat Pump
Your heat pump is designed to deliver comfort and peace of mind – let us help you to get the most from your sustainable heating system while you make your new house a home.
How It Works
Learn how your heat pump heats your home
Air source heat pumps work differently to traditional gas or oil boilers so your radiators may feel cooler to the touch, your heat pump will run for longer periods of time, and your heat pump will produce steady warmth and comfort not rapid bursts of heat. Watch our ‘Living with a heat pump’ video series to discover how your Grant heat pump system works, the key differences to look out for (which are completely normal) and useful tips to help you look after your heating system.
Controls
Controlling your Heat Pump
Heat pump controls play a key role in ensuring your heat pump system operates efficiently to fulfil your heating and hot water demands. Your heat pump is not designed to be switched off and settings such as weather compensation can help your heat pump to automatically adjust its operation based on the conditions outside. These and other settings are all managed by your heat pump controller so it is important that you understand which settings you can adjust and which you should leave to your installer.

An air source heat pump works more effectively and efficiently when it is maintaining desired temperatures and not recovering heat lost from the property. Heat pumps are therefore designed to operate continually using a cycle of “energised periods” and “setback periods”.
Read MoreNo, your heat pump should not be turned off at night – instead, your heat pump should be set to operate during a demand and setback cycles.
Read MoreHeat pumps will work at around -15ºC to -20ºC however a heat pump works best when the temperature is above 3 ºC or 4 ºC. When the temperature drops below 3 ºC, heat pumps operate less efficiently and will consume more energy.
No. An air source heat pump works more effectively and efficiently when it is maintaining desired temperatures and not recovering heat lost from the property meaning they are designed to operate continually during cold periods. Heat pumps should not therefore be switched off. Heat pumps are designed to suitably heat your property to a specified outdoor temperature - should the outdoor temperature fall below this system design temperature, there may be a need for supplementary heating. Alternatively, when using a heat pump in outdoor temperatures closer to freezing, then your thermostat timings should be altered to prevent any prolonged periods when the unit is not producing any heat.
Air source heat pump systems operate differently to traditional boilers as they are not designed to provide space heating and hot water at the same time.
Read MoreGrant's Aerona air source heat pumps feature an in-built 'defrost function' that will automatically operate when ice starts to form on the evaporator (outdoor oil) due to moisture in the air condensing and freezing on the evaporator in cold weather conditions. In brief, the defrost function will remove the ice by reversing the heat pump's operation and directing hot refrigerant vapour back into the ice-covered evaporator coil, causing the ice to melt.
Read MoreCaring for an air source heat pump is quite simple and looking after your Grant air source heat pump is straightforward. There are some steps, such as visual checks, that homeowners can follow to maintain a heat pump and help it to perform most efficiently. You are advised to regularly check that the air inlet grill and evaporator are free of leaves and debris and, in addition to this, the heat pump will need to be serviced on an annual basis, just like a traditional boiler.
Read MoreGrant heat pumps should be serviced annually. Failure to do so will invalidate the product guarantee.
Read MoreNo. Your Grant air source heat pump should be serviced annually by a heating professional who is a competent heat pump service engineer. Find local heat pump service engineers in your area.
Your Grant heat pump should be serviced annually and this can either be carried out by the heating engineer who installed your heat pump or by another competent heat pump service engineer. You can use Grant UK’s online engineer search to find local heat pump service engineers in your area. Alternatively, you can use Grant UK’s ServicePlan.
Read MoreA correctly designed and installed heat pump system should last at least 15 years (much like your fridge) provided it has been annually serviced and maintained each year. Like traditional heating systems, at the end of the boiler or heat pumps life, the remainder of the system should be checked for wear and tear and if nothing unto-wards is found, you would only need to replace the outside unit.
The refrigerant in an air source heat pump should not require replacing unless a leak is detected. If, during the annual service for example, a refrigerant leak is identified, this can only be remedied by a qualified engineer. Under no circumstances should the refrigerant be vented from the charging points on the refrigerant circuit of the heat pump and if any work is required to be carried out on the refrigerant circuit it MUST be undertaken by an F-GAS Registered Engineer.
Yes, the software on the Aerona Smart Controller can be updated via a micro SD card which is loaded with the latest software and can be inserted into the touchscreen display. If a software update is available, these updates should be carried out by your Grant UK G1 heat pump installer, during the annual service for example.
The best way to operate your heat pump efficiently and effectively is to make sure all external doors and windows are closed. This ensures that the heated air stays inside the property and maintains your desired temperature. It is important to note that it is still very important to ventilate your property so we encourage you to intermittently open windows for short periods, or to use trickle ventilation facilities if available.
The SCOP means Seasonal Coefficient of Performance which is a way of measuring the true energy efficiency of heating and cooling technology over an entire year. This measure gives a more realistic indication of the energy efficiency and environmental impact of a system. This is indicated as a ratio for energy required to run the heat pump compared to the amount of energy being produced by the heat pump for typical day to day use. A heat pump with a SCOP of 4 means that for every 1kW of energy used to run the heat pump, 4kW will be produced.
Weather compensation is a way of modifying the heating system output according to the temperature outside by simultaneously monitoring indoor and outdoor temperatures. The water used to heat your property within the heating system will become hotter if the outside temperature declines, and vice versa.
Weather compensation regulates and maintains an optimum flow temperature which can help prevent changes in the heat pump’s functioning. It prevents the appliance starting up or shutting off when a property is too hot or too cold.
The ecoNET app provides homeowners and installers with remote access and control of their Aerona Smart heat pump system controller. It is compatible with both iOS and Android devices and it can be downloaded via the App Store and Google Play. A web-based version of the ecoNET is also available which provides additional functionality and information for customers. Please visit the Grant UK YouTube Channel to watch a video tutorial which provides an overview of the ecoNET app.
The ecoNET web-based platform provides additional remote monitoring and management access of the Aerona Smart Controller. There are two types of access to the ecoNET platform – one for homeowners and one for installers. If you have an Aerona Smart Controller installed in your home and you want to set up an account with ecoNET, please watch our tutorial video which talks through the steps involved in setting up a homeowner account.
We do not recommend painting an air source heat pump. However, some companies provide a wrapping service which can cover a Grant air source heat pump with a durable material that incorporates a pattern or colour which is more in-keeping with the local surrounds. We would suggest contacting your local installer to discuss this further as it important than any wrap or covering put on the heat pump does not impair its operation.
Where electricity is the only energy source used, a change to the electricity tariff might be possible enabling the heat pump to run more economically. It is always worth enquiring with your energy provider, as depending upon your electricity demand, they may have a plan that is more suitable e.g. Economy 10.
No. Grant UK do not outsource annual product maintenance agreements like their ServicePlan offering. The Grant UK Team would never call you unprompted to ask for credit card or banking details over the phone – please be alert to potential scams if you receive a cold call asking for your card or banking details.
