Why Choose Heat Pumps
Join the renewable revolution. Air source heat pumps deliver unmatched efficiency, lower bills, and year-round comfort whilst reducing your carbon footprint.
For every unit of electricity used, heat pumps produce 3-4 units of heat. That's up to 400% efficiency compared to 90% for the best gas boilers.
Save up to 50% on your heating costs compared to traditional systems. With energy prices rising, there's never been a better time to switch.
Modern heat pumps work efficiently even in temperatures as low as -25°C. Perfect for North Devon's climate, providing reliable heating all year round.
With a lifespan of 20-25 years and minimal maintenance requirements, heat pumps outlast traditional boilers by up to 10 years.

"Deane from Integrity recently fitted a new heat pump and water cylinder to my house. He was very patient with my constant questions about the tech and performance expectations. All the work pipe runs, methods and kit he recommended was of the highest standard. After a few months running I can see the benefit. Consistently warm house and hot water with good running costs. Heat pumps work and Deane is the man!"

Lifetime SupportEverything you need to know about air source heat pumps in Barnstaple and North Devon
Air source heat pumps extract heat from the outside air and transfer it into your home. Even when it feels cold outside, there's still heat energy in the air that can be captured and amplified. The system works like a refrigerator in reverse, using a refrigerant to absorb heat from the air and compress it to a higher temperature before distributing it through your heating system.
Most homes in Barnstaple and North Devon are suitable for air source heat pumps, particularly those with good insulation and adequate space for the outdoor unit. Properties with underfloor heating or larger radiators are ideal, but many standard homes can be adapted. We offer free home surveys to assess your property's suitability and recommend any necessary upgrades to maximise efficiency.
The Boiler Upgrade Scheme is a government initiative offering £7,500 grants to homeowners in England and Wales who install air source heat pumps. This grant significantly reduces the upfront cost of installation. We handle all the paperwork and applications on your behalf, making the process straightforward and hassle-free for North Devon residents.
Savings vary depending on your current heating system and energy usage, but most homeowners in Barnstaple switching from gas boilers save £300-£600 annually. Those replacing oil, LPG, or direct electric heating can save even more—sometimes over £1,000 per year. Heat pumps are incredibly efficient, producing 3-4 units of heat for every unit of electricity consumed.
Modern air source heat pumps are remarkably quiet, typically operating at around 40-60 decibels—comparable to a modern refrigerator or quiet conversation. We carefully position the outdoor unit away from bedrooms and neighbouring properties to minimise any sound. Most homeowners in Barnstaple report they rarely notice their heat pump running.
In most cases, no. Air source heat pumps typically fall under permitted development rights in England, meaning you won't need planning permission. However, there are some exceptions for listed buildings, conservation areas, or flats. We'll advise you on any requirements specific to your North Devon property during your free consultation.
Air source heat pumps have an expected lifespan of 20-25 years with proper maintenance—significantly longer than traditional gas boilers which typically last 10-15 years. With fewer moving parts and no combustion process, they're incredibly reliable. We provide comprehensive warranties and annual servicing packages to ensure your system operates efficiently throughout its lifetime.
Yes! Air source heat pumps can provide both space heating and domestic hot water. They work alongside a hot water cylinder to ensure you have plenty of hot water whenever you need it. Many of our Barnstaple customers find their hot water is just as reliable as with their old boiler, often with improved efficiency and lower running costs.
You can have various different control options on an air source heat pump. You can control your heating and hot water systems for timings and temperatures just like a gas boiler, however we would always recommend using a constant day temperature and constant night time set back temperature whilst using something called weather compensation. If you can secure a lower night time electric tariff we would design the system to maximise that usage to build a thermal mass within the property to lower usage in the day time. Weather compensation allows the heating system to understand inside and outside temperatures. If the temperature drops externally then we can counter than with a similar internal boost of heat. This stops the fabrication of the building to drop temperature and provides a more stable and gentle to heat for your home.
