Ground Source Heat Pump Installation in Chorley, Lancashire

It sounds like something from a sci-fi film, doesn’t it? Extracting heat from the cold ground during a Lancashire winter? But it’s actually incredibly simple physics. Even when it’s freezing outside, the earth about a metre or two down stays at a remarkably constant 10–12°C all year round. A ground source heat pump uses a mixture of water and anti-freeze (often called glycol) that circulates through pipes buried in your garden. This fluid absorbs that natural geothermal heat and carries it to the heat pump inside your home. It then compresses that heat to a higher temperature, providing you with lovely, consistent warmth and mains-pressure hot water. It’s essentially like a fridge working in reverse. Instead of taking heat out of a box and dumping it in the kitchen, it takes heat from your garden and brings it into your living room.

One of the first questions we get asked when we visit a site in Chorley is, "Do I have enough room for this?" The answer usually depends on your garden layout. If you’re lucky enough to have a fair bit of space or even a paddock, we often recommend horizontal ground loops. We dig trenches about a metre deep and lay the pipework in coils. It’s a cost-effective way to get the job done if you don’t mind a bit of a dig. However, if space is tighter, don’t panic. We can use vertical boreholes instead. We bring in a specialist rig to drill down—sometimes up to 150 metres deep—to extract the heat. We then use high-quality thermal grout to seal everything up and ensure the best possible heat conductivity. It’s a much smaller "footprint" on the surface, making it perfect for modern Lancashire homes.

For those living in the more rural parts of Chorley who rely on oil or LPG, a ground source heat pump is a total game-changer. Imagine never having to worry about an oil delivery truck again or checking the levels in a big, ugly tank in the garden. Because GSHPs are incredibly efficient—often reaching a Seasonal Coefficient of Performance (SCOP) of 4.0 or higher—you get roughly 4kW of heat for every 1kW of electricity used. That’s 400% efficiency. Compare that to a brand-new A-rated gas boiler which is usually around 92% efficient, and you can see why the savings start to add up. It’s "fit and forget" technology; the ground loops are designed to last for over 50 years, meaning you’re future-proofing your home for decades to come.

Installing a ground source heat pump isn’t just about digging a hole; it’s about precision engineering. We start every project with a detailed heat load calculation to make sure the system is perfectly sized for your specific rooms and insulation levels. As a Gas Safe registered (967977) team with #10 million in public liability insurance, we take safety and compliance seriously. We’re also fully qualified to handle unvented hot water cylinder installations, ensuring you get that powerful shower pressure you’ve always wanted. From the initial geological survey to the final commissioning of the manifold chamber, we manage every single step. We’re local lads who take pride in our reputation across the North West, so we won’t leave you in the lurch. We’ll even show you how to use your new smart thermostat to keep your heating zones exactly where you want them.
