Why choose an air source heat pump?
Practical benefits only land when the system is designed around the building, emitters, hot water demand and controls.
AquaTherma specifies the whole heating strategy, so the outdoor unit, cylinder and heating circuits work together instead of behaving like separate products.
Works with radiators or UFH
Specified around real heat loss, flow temperatures and everyday comfort.
Hot water included
Cylinder, controls and heating design planned as one complete system.
MCS certified installation
Installed properly for compliance, performance and long-term peace of mind.
How it works
From outdoor air to warm rooms and reliable hot water.
An air source heat pump collects heat from outside air and transfers it into a water-based system. The design work decides how efficiently that heat reaches the cylinder, radiators, UFH and controls.
Outdoor unit
Collects heat from outside air.
Hot water cylinder
Stores domestic hot water.
Radiators or UFH
Delivers low-temperature comfort.
Controls
Keeps comfort and efficiency aligned.
The important bit is the design between those parts: heat loss, flow temperature, cylinder sizing, pipework, controls and commissioning.
Suitability
Is an air source heat pump right for your home?
Air source heat pumps can work well in new builds, renovations and suitable existing homes, but the design needs to be based on insulation, radiators, UFH, hot water use and controls.
Best for
Properties where low-temperature heating can be designed properly.
- Well-insulated homes
- Underfloor heating
- Suitable radiators
May need upgrades
Some homes need supporting changes before a heat pump is the right move.
- Radiators
- Cylinder
- Controls or insulation
AquaTherma checks
The design is based on measured suitability, not guesswork.
- Heat loss
- Flow temperatures
- Hot water demand

Answers to the practical questions that come up before committing to a heat pump design.
Still unsure if an air source heat pump is right for you?
Send us your property details and we will advise the best next step.
Send property detailsDo heat pumps work with radiators?+
Yes, when the radiators, heat loss and flow temperatures are designed correctly. AquaTherma focuses on low temperature design so radiators, UFH and hot water work efficiently as a complete system.
Is underfloor heating better for a heat pump?+
Underfloor heating is often an excellent partner for heat pumps because it can deliver comfortable heat at lower water temperatures. The detail still needs to be designed around the property and floor construction.
What is SCOP?+
SCOP means Seasonal Coefficient of Performance. It is a seasonal efficiency measure that describes how much heat a heat pump delivers compared with the electricity it uses.
Do you cover my area?+
AquaTherma works across Lincolnshire, Nottinghamshire, Cambridgeshire, Norfolk and Leicestershire. If you are nearby and unsure whether your project is covered, send your postcode and the team will confirm.
Are you MCS certified?+
Yes. AquaTherma is MCS certified and is also a RECC member.
Do you work with developers and heating engineers?+
Yes. AquaTherma works with homeowners, self-builders, developers and plumbing or heating engineers, including design and commissioning support where appropriate.
