What is a Hybrid Air Source Heat Pump?

A hybrid heat pump cleverly combines an outdoor air source unit and a traditional gas combi boiler into a single system. The heat pump extracts thermal energy from the outside air – think of it as working like a fridge in reverse – and uses it to heat your water. Hybrid air source heat pumps are highly efficient, but as most UK homes aren’t perfectly insulated, the gas boiler steps in during colder months to keep your heating at the levels you expect. This hybrid boiler and heat pump setup means reliable hot water and heating all year round, but with lower gas use and carbon emissions.

Our Range Of Hybrid Air Source Heat Pumps And How They Work

Our Xtend hybrid heat pumps are expertly designed to deliver comfort, efficiency and reliability. Each system (either Xtend Split Hybrid or Xtend Monobloc Hybrid) combines a compact electric heat pump with a gas combi boiler, lowering gas use without compromising the hot water or warmth you rely on every day. Here are the essentials:

Key Components:

Air Source Technology
Smart Hybrid Control
Year-Round Comfort

Air Source Technology

The outdoor unit draws in air, compressing a refrigerant inside to raise its temperature before transferring the heat indoors through a heat exchanger.

Smart Hybrid Control

The electric heat pump/boiler system is automatically managed, choosing whether the boiler, the heat pump or both should run for the most efficient result.

Year-Round Comfort

In mild weather, the heat pump does the work. When temperatures then drop, the gas boiler kicks in to support the system, keeping your heating and hot water consistent.

Frequently Asked Questions

How does a hybrid air source heat pump work?

Hybrid heat pumps work by combining two systems: an outdoor heat pump and a combi gas boiler. The outdoor unit draws in air and passes it over a refrigerant, which is compressed to raise its temperature. This heat is then transferred indoors to heat your home. During colder months or when demand is higher, the boiler can kick in and provide additional support. This hybrid boiler and heat pump setup delivers exceptional efficiency in mild weather, reliability in winter and hot water on demand year-round, giving you the best of both worlds in a single system.

What size electric heat pump do I need?

Xtend hybrid systems use a 5kW outdoor unit paired with a gas combi boiler. This system allows the heat pump to handle the majority of your home’s heating needs, while the boiler provides additional support when required. Our air source heat pump installers will carry out a full assessment to recommend the right system for your home.

Are hybrid heat pumps energy efficient?

Yes, hybrid heat pumps are specifically designed for efficiency, and can cut gas usage by as much as 82.5% when paired with a modern combi boiler like the ones developed by Intergas. You can use our boiler finder tool or talk to our experts to ensure you get the ideal boiler unit for your new system.

Do hybrid heat pumps need servicing?

Yes, hybrid air source heat pumps should be serviced once a year to keep them safe, efficient and reliable. Regular checks help spot issues early and maintain your warranty. At Intergas, you can book your annual boiler servicing alongside your heat pump for complete peace of mind.
