Air Source Heat Pump
Air Source Heat Pumps in Pembrokeshire
Upgrade to low-carbon, energy-efficient heating with a professionally designed air source heat pump system from Del Brace Plumbing & Heating. We install heat pumps across Tenby, Saundersfoot, Pembroke, Haverfordwest and the wider Pembrokeshire area.
What Is an Air Source Heat Pump?
An air source heat pump is a low-carbon heating system that extracts thermal energy from the outside air and uses it to heat your home and hot water. It is an alternative to conventional oil and gas heating and can suit a wide range of properties when designed properly.
Heat pumps work best as part of a well-planned system. That means looking at insulation, radiator sizing, hot water storage and how your home is used day to day. Our role is to survey your property properly and recommend a system that is right for your home.

How Does an Air Source Heat Pump Work?
Air source heat pumps work like a fridge in reverse, collecting heat energy from the outside air and transferring it into your home’s heating and hot water system.
Heat energy is absorbed from the outside air and transferred into the refrigerant.
The refrigerant is compressed which increases its temperature ready to deliver useful heat.
That heat is passed into the water for your radiators, underfloor heating and hot water cylinder.
The refrigerant cools, resets and the cycle repeats continuously to provide heating and hot water.
Is My Home Suitable for a Heat Pump?
Many homes in Pembrokeshire can be suitable for an air source heat pump, but the only proper way to know is with a survey and heat loss calculation.
In general, homes are often a good fit where there is space outside for the unit, room for a hot water cylinder, reasonable insulation levels and willingness to upgrade some radiators if needed.
You May Be a Good Fit If:
- You want a modern low-carbon alternative to oil or gas heating
- Your property has space outside with good airflow
- You have or can accommodate a hot water cylinder
- Your home is reasonably insulated or can be improved
- You are happy to use larger radiators or underfloor heating where needed
- You want consistent comfort and a professionally designed system

Heat Pump Systems for Different Homes
Every property is different, which is why we size and design systems around the home rather than offering one-size-fits-all solutions.
Two to Three Bedroom Homes
Often suitable for a compact heat pump system with new hot water cylinder, controls and targeted radiator upgrades where needed. A survey allows us to confirm the right output and design for your property.
Larger or Older Properties
Older and larger homes can still be suitable for a heat pump, but they usually benefit from detailed design, insulation considerations and a closer look at radiator performance and hot water demand.
Heat Pump Servicing & Priority Service Plan
Like any heating system, an air source heat pump should be serviced every year to keep it running efficiently, safely and reliably.
