For those on mains gas, switching to a full electric air source heat pump system may not be financially beneficial. However, if you want to future proof your home and protect yourself from unpredictable energy rises AND do your bit for the environment, a hybrid system could be a perfect option.
A hybrid heating system combines the gas boiler, with an air source heat pump. The technology integrates both heating systems, using smart programming to automatically determine the most energy efficient one to use based on energy prices, temperatures, and indoor heat capacity. By making the most out of both technologies, a Hybrid Air Source Heating system can help save up to 35% more energy than the traditional boiler could alone.
The use of a hybrid heat pump takes advantage of renewable energy extracted from the air and can achieve up to A++ efficiency to heat the home and provide hot water. Using a hybrid air source heat pump system means you will have reliable heat all year round with the boiler taking over in cold temperatures and the heat pump taking over when it is warmer preventing you from using unnecessary gas.
Types of Hybrid Air Source Heat Pump Installation & Benefits
With regular boilers a hot water cylinder is required for storing hot water, unlike for combination boilers that heat water directly from the mains when a hot water tap is turned on.
Hybrid heat pumps can operate with either regular or combination boilers depending on the application. As the government develops its net-zero policy to phase out fossil fuel heating, people using a hybrid system may later need to make changes to their boiler or their home’s insulation, to make sure their next heating system can be fully low carbon. You will need to consider whether this would suit your needs, or whether you would prefer to install insulation and/or a low carbon technology such as an air source heat pump (without a boiler) straight away.
Regular Hybrid Heat Pump System
A regular hybrid heat pump system – with a regular boiler, hot water cylinder and electric heat pump – can optimise for space heating and/or hot water. The single control prioritises the fuel source, operating temperatures and demand priority to the heat emitters and hot water store. Heat pump cylinders are available for demand-side response (with boiler, heat pump, photovoltaic (PV) and battery options). Thermal stores also provide a buffer for heating and/or hot water.
Also a regular central heating infrastructure enables greater scope for integration, with radiant heating from radiators or underfloor heating, also air conditioning for the warner months.
Combi Hybrid Heat Pump System
Combination hybrid heat pumps use the gas combi boiler and heat pump to optimise only the space heating with the control. The boiler then provides all of the instantaneous hot water on demand. This approach avoids the additional expense and space needed to install a new hot water storage tank, especially for those combination boiler installations where there is limited Hybrid systems which combine an air source heat pump and fossil fuel boiler may be suitable for a wide range of homes, although you will need to consider whether your home is insulated enough for the heat pump to run efficiently. This is so that the system can run mostly on low carbon heat, keeping your home warm without much input from the boiler.
Hybrid Air Source Heat Pumps - Benefits
Hybrids using a smaller heat pump can still meet 80% of a household’s annual energy demand, without making changes to the existing heating system
Hybrids can be fitted to a large number of the 15 million homes that already have a combination boiler, causing far less disruption for the homeowner
Hybrids are more flexible to install and produce less noise compared to an all-electric heat pump installation
Adding a smaller heat pump and hybrid control to an existing boiler creates a hybrid heat pump at a relatively low cost
Users can spread investment in property renovation over time to improve insulation and transition to a low-temperature system, reducing carbon emissions while also maintaining comfort
Heat pump and hybrid controls can be fitted to different heat sources and boiler types such as regular or combination boilers
Hybrid Air Source Heat Pumps - Benefits
Hybrid heat pumps offer better choice and adapt the home for both low-electricity and low-carbon gas technologies (including 100% hydrogen),
The introduction of a hydrogen blend with natural gas will deliver further carbon savings when using the boiler as part of the hybrid system, be this regular or combination type
For homes with a hot water cylinder, there is the potential to use off-peak electricity for heating and storing hot water to balance the energy supply
Heat pumps can run on off-peak electricity with a temperature set back to maintain comfort in winter temperatures.
The combination of a heat pump with an LPG or oil condensing boiler along with biofuel can significantly reduce carbon emissions
