Additional Information

01. DOWNLOAD PRODUCT DATA SHEET

Data Sheet

02. WHAT MAKES AN AIR SOURCE HEAT PUMP ECO-FRIENDLY?

Air source heat pumps use renewable heat from the outside air and require much less energy than traditional boilers to produce the same level of heating. This results in lower carbon emissions and reduced reliance on fossil fuels, especially when powered by low-carbon electricity.

03. IS THIS AIR SOURCE HEAT PUMP SUITABLE FOR MY PROPERTY?

Cool Energy air source heat pumps are suitable for most UK homes, including new builds and retrofits. They work best in well-insulated properties and are compatible with underfloor heating and oversized radiators. If you’re unsure, a heat loss calculation will confirm suitability.

04. CAN AIR SOURCE HEAT PUMPS REPLACE MY EXISTING GAS OR OIL BOILER?

Yes. Cool Energy air source heat pumps are designed to replace gas, oil, or LPG boilers. In most cases, the existing heating system can be adapted, although some radiator upgrades may be required to maximise efficiency.

05. HOW EFFICIENT IS A COOL ENERGY AIR SOURCE HEAT PUMP?

Cool Energy heat pumps typically achieve high seasonal efficiency (SCOP), meaning they produce multiple units of heat for every unit of electricity used, making them far more efficient than traditional boilers.

06. HOW MUCH WILL IT COST TO RUN COMPARED TO A GAS BOILER?

Cool Energy heat pumps typically achieve high seasonal efficiency (SCOP), meaning they produce multiple units of heat for every unit of electricity used, making them far more efficient than traditional boilers.

07. CAN THIS HEAT PUMP WORK WITH MY EXISTING HOT WATER CYLINDER?

In some cases, yes. However, many installations benefit from a heat-pump-ready cylinder or buffer tank to ensure correct temperatures and system performance.

08. HOW NOISY IS THE OUTDOOR UNIT?

Cool Energy air source heat pumps are designed for low-noise operation and comply with UK noise regulations. In most cases, the sound level is comparable to a modern fridge or quiet conversation.

09. HOW MUCH SPACE DOES THE SYSTEM NEED?

The outdoor unit requires a small external footprint, similar to an air conditioning unit. Internally, space may be required for a hot water cylinder or buffer tank, depending on your setup.

10. ARE COOL ENERGY AIR SOURCE HEAT PUMPS ELIGIBLE FOR THE GOVERNMENT GRANT SCHEME?

Yes, Cool Energy air source heat pumps are eligible for the UK Government’s Boiler Upgrade Scheme, subject to meeting the scheme’s criteria. Eligibility depends on the specific model, property suitability, and installation by an MCS-certified installer, who will confirm eligibility and apply for the grant on the customer’s behalf if applicable.
