Sustainable solutions you can trust
What is an exhaust air heat pump?
An exhaust air heat pump (EAHP) captures warm indoor air—usually from kitchens, bathrooms, and utility rooms—and recycles that energy to provide heating through radiators or underfloor, hot water, and ventilation. This compact, all-in-one solution sits entirely indoors, making it perfect for self-builders creating their forever home and developers planning sustainable, space-efficient projects.
Why EAHPs Beat Air & Ground Source Systems
- All-in-One Solution – Heating, hot water, and ventilation in a single unit— no separate systems.
-
No Outdoor Unit – Solves aesthetic, noise, and planning challenges common with air source heat pumps.
-
No Groundworks – Unlike ground source systems, no drilling or digging is required—cutting cost and disruption.
-
Consistent Efficiency – Indoor air is a stable heat source, so performance doesn’t drop in cold weather.
-
Perfect for New Builds – Works best in modern, airtight homes where heat loss is minimised.
Award-winning EAHPs like the NIBE S735 are already trusted in UK developments. They meet modern building regulations, deliver reliable comfort year-round, and can be paired with solar PV and battery storage for next-level energy independence.
For self-builders and developers, they’re a compact, efficient, future-proof solution that makes greener living simple.

FAQs
How do air source heat pumps work?
Heat pumps operate by transferring heat from one location to another using a refrigeration cycle. They extract heat from the outside air and then transfer and amplify it to warm your property and heat your water.
How do I know if I need an air source or a ground source heat pump?
This will likely depend on the outdoor space you have available and the geology under your home. Our team can advise which option is best for your home after completing a site survey.
What are the benefits of installing a heat pump?
Installing a heat pump offers several benefits, including reduced energy bills, year-round comfort with both heating and cooling capabilities and lower carbon emissions. According to recent research, adding a heat pump to your home can improve your property value by around 3%.
I’m considering replacing my boiler with a heat pump. Are there any incentives to supplement the installation cost?
We’re on hand to help you discover what solution is best suited to your home and help you claim your £7500 support from the Government’s Boiler Upgrade Scheme. To learn more or request a complimentary site specific quote contact us here.
Are heat pumps energy-efficient?
Yes, heat pumps are known for their energy efficiency. Because they move heat rather than generate it through combustion, they can provide up to four times the amount of energy they consume, making them an environmentally friendly and cost-effective heating solution.
