It is one of the most common questions we hear from homeowners across South East London: “Do I have to get rid of my gas boiler to install a heat pump?” The short answer is no. An air source heat pump can be installed alongside an existing gas boiler in what is known as a hybrid heating system.
But whether that is the right choice for your home depends on a few key factors.
How Does a Hybrid System Work?
A hybrid setup uses both an air source heat pump and a gas boiler to heat your home. The heat pump handles the bulk of the work, providing efficient, low carbon heating at lower flow temperatures. When the temperature drops significantly or when there is a sudden spike in hot water demand, the gas boiler kicks in to support the system.
A smart controller switches between the two based on which energy source is more cost effective at any given time. This means your home stays warm without relying entirely on one system.
When Does a Hybrid Setup Make Sense?
A hybrid system can be a practical option if your property is not yet fully insulated or if upgrading your radiators to work with lower flow temperatures is not something you are ready to do straight away. It allows you to benefit from renewable energy now while planning for a full switch later.
It can also suit older homes where a complete heating system replacement would require more extensive work.
Why Many Homeowners Choose a Full Heat Pump Installation
While hybrid systems have their place, most of our customers choose to go fully renewable, and for good reason.
A standalone air source heat pump generates around 75% of the energy it uses from the outside air. That means lower running costs, reduced carbon emissions, and no ongoing reliance on gas. With the £7,500 Boiler Upgrade Scheme grant covering a significant portion of the upfront cost, the switch is more affordable than many homeowners expect.
At Air To Heat, we are MCS certified installers approved by the government to apply for the grant on your behalf. We work with leading manufacturers including Grant and Vaillant to design systems that suit your home and deliver long term savings of 25 to 40% on heating bills.
