FAQ: Has my home got space for a heat pump?

If you’re like many UK homeowners, you might be exploring the idea of installing a heat pump to heat your home more efficiently. But is there space for one in your home?

The good news is that there’s likely a heat pump that can work for your space, whether it’s a ground source, air source, or water source model. Let’s break it down to help you decide.

Ground source heat pumps

Perfect for homes with large gardens, these pumps use trenches dug about a metre underground to capture heat. If you’ve got the space, they can be a great option – but they’re a little trickier for smaller plots.

Water source heat pumps

These pumps need access to a nearby body of water, like a river, lake, or large pond. If you have this option, it’s worth exploring – but it’s not common for most homes.

Air source heat pumps

By far the most space-efficient, these need only a spot on an external wall with good airflow. The outdoor unit is about the size of a washing machine, and inside, your current boiler is replaced by a compact unit that manages the system.

“The concept may seem strange to us, but actually, in all our homes we have fridges, and an air source heat pump is very much like a fridge working back-to-front.”

Geordie Stewart, Cosy Homes Oxfordshire Scheme Manager

Key considerations for heat pumps

f you’re thinking about a heat pump, there are a few things to keep in mind:

Flat or apartment living: External units can sometimes be roof- or wall-mounted – but always check compatibility with your building’s heating system.

Insulation is key: Heat pumps work best in well-insulated, airtight homes. Improving insulation first will help you avoid needing a larger, less efficient system.

Indoor space: You may need room for a new hot water cylinder designed for heat pumps.

Heat pumps are incredibly efficient, often producing three times the energy they consume – and when paired with renewable electricity, they’re even better for the planet.

Before installation, we recommend improving insulation and glazing to get the most from your new system. And when you’re ready, working with an MCS-certified installer ensures everything runs smoothly.

Through Cosy Homes Oxfordshire, we can connect you with trusted, experienced professionals and guide you through the process, so you can heat your home sustainably and comfortably.
