What Are Hybrid Heat Pumps and Are They the Future?
As the world moves towards more sustainable ways of using energy, attention in the home heating sector is increasingly turning towards hybrid heat pumps. These clever devices combine a hybrid air source heat pump with a traditional gas boiler, creating a smart heating system that cuts gas use without compromising comfort. Let’s have a closer look at how it all works.
What Is a Hybrid Heat Pump?
In short, a hybrid heat pump is a type of heating system that combines a hybrid air source heat pump with a traditional gas boiler. The heat pump does most of the work by drawing warmth from the outside air, but the boiler can still step in during colder periods or during high demand on the system, ensuring comfort year-round.
How Does a Hybrid Heat Pump Work?
These systems work by ingeniously combining two different technologies into a single heating system for your home. The heat pump extracts thermal energy from the outside air, even in colder weather, and transfers it indoors through a refrigerant and heat exchanger.
It sounds complex, but it works like a fridge in reverse and is efficient and advanced enough to provide heating without relying on gas for much of the year. If outdoor temperatures drop very low or there is a higher demand for hot water in your home, the gas boiler still steps in to deliver it. The two systems are automatically switched, ensuring complete ease of use and efficiency.
Hybrid or Bivalent Heating Systems?
Hybrid and bivalent heating systems both combine a heat pump with a boiler, but they’re not quite the same. A hybrid heat pump is a packaged solution from one manufacturer, with the boiler and heat pump working together under a single control system – like the Xtend Monobloc and Xtend Split systems that we provide here at Intergas. A bivalent system pairs any heat pump with an existing boiler. In most cases, this means the controls are set so the heat pump does most of the work, while the boiler is set to kick in at a certain threshold to keep temperatures consistent.
Tariff Controlled Heating Systems
A tariff controlled heating system intelligently switches between your heat pump and boiler based on current energy tariffs. Rather than relying on a single heating source, the system chooses the most cost-effective option. The advanced system selects the best option specifically for producing the required amount of heat.
What are the Benefits of Hybrid Heat Pumps?
Enhanced comfort
Hybrid heating systems are ideal for maintaining comfortable indoor temperatures. They provide a dynamic combination of efficient everyday heating from a heat pump, while the boiler delivers additional heat during periods of colder weather.
Lower energy bills
Hybrid systems help reduce energy bills by using a heat pump that extracts heat from the ambient air outside. As heat pumps produce more heat than the electricity they consume, they can lower running costs while the boiler provides additional support when needed.
Low maintenance
The streamlined design of hybrid heating systems makes maintenance simple. Basic maintenance includes keeping the outdoor unit free from debris, checking filters where recommended by the manufacturer and scheduling an annual service.
Energy-efficient
By combining two heating technologies, hybrid heat pumps maximise energy efficiency throughout the year. The system uses the most suitable heat source to meet your specific demands, helping to reduce energy consumption.
When Is a Hybrid Heat Pump a Good Idea?
If you’re deciding whether a hybrid heat pump is the right choice for your home, consider the following common scenarios to see if one matches your heating needs.
- You want to upgrade your existing boiler – Those with older or less efficient boilers can be costing you severely. An upgrade can be advantageous and more cost-effective in the long term.
-
- You are interested in limiting your energy usage – Hybrid systems are ideal for homeowners looking to reduce energy consumption.
- You have existing radiators – This is beneficial as heating systems can be integrated with existing radiators, making for a seamless installation.
- You want dependable heating all year – Hybrid systems adapt to provide consistent heating. Unlike traditional boilers, which typically deliver short bursts of intense heat, hybrid pumps help maintain a more stable indoor temperature.
How Much Do Hybrid Air Source Heat Pumps Cost?
The cost of a hybrid system will vary depending on your property, the system you choose and other installation requirements. Costs range between £2,500 and £5,000 which also include installation and manufacturer warranties. Additional costs may apply if your property requires upgrades or updates to your existing heating system.

What to Consider When Investing in a Hybrid Heating System
A hybrid system can be an excellent investment in the comfort of your home, alongside the potential energy savings.
Purpose
If you’re looking for a heating system that balances efficiency, comfort and reliability, a hybrid heat pump could be the ideal solution. It combines the efficiency of a heat pump with the dependable performance of a boiler, creating an adaptable heating system that puts you in control of your home’s heating.
Configuration
Hybrid heat pumps are designed to work alongside your existing boiler and heating system. They can often integrate with your current radiators and pipework, making them suitable for many homes.
Operation
The heat pump typically provides efficient everyday heating, while the boiler supports the system during colder weather or periods of higher heating demand. Together, they deliver reliable performance and consistent comfort all year round.
Why Are Hybrid Air Source Heat Pumps Paving the Way in the Future?
The UK has set itself the target of reaching net zero carbon emissions by 2050, and finding more efficient ways to heat our homes is a major factor in achieving this. Domestic heating currently accounts for almost one-fifth of our greenhouse gas emissions as a nation, so a new method of keeping ourselves warm is needed to help us reduce our reliance on fossil fuels. This is where hybrid air source heat pumps come in.
For homeowners asking, “What are hybrid heat pumps?”, they could very much be the solution we need. As we’ve discussed, the pump does most of the heating, with a gas boiler providing support only when needed. It’s not quite as eco-friendly as just switching to a stand-alone heat pump, but it does cut gas use significantly without requiring homes to undergo costly insulation upgrades or major system alterations, such as radiators that work better at lower temperatures.
High-temperature heat pumps are now more efficient than ever, allowing households to reduce carbon emissions immediately, while preparing for a fully renewable future. For many properties, especially larger or older homes, a hybrid heat pump provides the perfect balance between sustainability, reliability and affordability, helping significantly reduce greenhouse gas emissions.
Hybrid Heat Pump Manufacturing
For homeowners considering hybrid air source heat pumps, choosing a trusted manufacturer makes such a difference. Intergas has been innovating in the heating industry since 1939, and today we offer two advanced and highly efficient hybrid solutions: the Xtend Monobloc and the Xtend Split. Both options deliver immediate carbon savings and long-term heating reliability.
Both combine a 5kW air source heat pump with an Intergas combi boiler to help cut your gas use by up to 82.5%, bringing down your energy bills without compromising your year-round comfort. Our highly efficient systems can even be retrofitted to existing compliant boilers.
Is There Any Financial Support for Hybrid Heat Pumps?
At the time of writing, hybrid heat pumps are not eligible for government grant schemes like the Boiler Upgrade Scheme from the UK government, which only supports standalone air source heat pumps, ground source heat pumps and biomass boilers. However, hybrid systems can still deliver significant long-term savings by cutting your gas use by up to 82.5%. Installation costs are also significantly lower compared to a full heat pump system.
What Are Hybrid Heat Pumps | FAQs
Do hybrid heat pumps need servicing?
Yes, like any heating system, heat pump systems need regular maintenance to ensure safety, efficiency and reliability. An annual boiler servicing appointment is the best way to protect the performance of your hybrid air source heat pump system and help extend its lifespan.
