How a heat pump works
A heat pump is essentially a refrigeration system in reverse. Instead of burning fuel, it extracts heat from the outside air and concentrates it to warm your home and hot water. For every 1kW of electricity used, a well-installed heat pump typically delivers around 3–4kW of usable heat — making it significantly more efficient than a gas or oil boiler. Heat pumps have been the standard heating technology across much of Europe for over 30 years, with more than 21 million installed as of 2023.
What’s involved in a heat pump installation
Every property is different, so we start with a full heat loss survey rather than a generic quote. Typical steps:
- Site survey and heat loss calculation — we assess insulation, radiators/underfloor heating, hot water demand, and where the outdoor unit can sit
- System design — sizing the heat pump, cylinder, and any radiator or pipework changes needed
- Boiler Upgrade Scheme application — we handle this on your behalf if you’re eligible
- Installation — typically one week for a straightforward retrofit
- Commissioning and handover — including a full explanation of your controls
Air source vs ground source: which is right for you
Most Gloucestershire homes are well suited to air source heat pumps (ASHP) — lower installation cost, no groundworks needed, and strong performance even in cold weather. Ground source heat pumps (GSHP) offer slightly higher efficiency and are quieter, but need enough garden space (or a borehole) and a bigger upfront investment. We’ll recommend the right fit after your survey rather than a one-size-fits-all answer.
Case Study
Banbury Barn Project
Stiebel Eltron WPL 25 ASHP/ MVHR/ Unico/ Underfloor heating
The Challenge
Jody and James were half way through their build when their original installers went bankrupt. They needed an installer who could help integrate the technologies; they wanted to reduce the cost of running their home and provide year round comfort.
The Solution
PBT Installations recommended some changes to the original installation plans to maximise results and helped create the home Jody and James had set out to build.
An integrated system that allowed the house to stay at desired temperatures, utilising MVHR and Unico systems to keep fresh air flow whilst the heat pump and underfloor heating keeps the house comfortable in colder weather.
Solar PV
PV panels were added to the roof to help generate energy and offset running costs
Battery Storage
The couple plan to add Battery storage in due course to help maximise off-peak tariffs
With PBT’s help, we feel confident that the technology we have installed is the right choice for our property.
