Why Choose Bath Eco Heat for Boiler Installation in Nailsea
We know people are careful about who they let into their homes — especially when it involves the heating. Here’s what you can expect from us.
Honest, Fixed Pricing
We give you a written quote before any work starts. That’s the price you pay. No extras tacked on at the end, no awkward conversations on the day. If something unexpected comes up during the install, we talk to you first.
✅
Clean, Respectful Work
Dust sheets go down before we start, and everything gets tidied up before we leave. We don’t leave a mess. Your home should look the same as it did before we arrived — just with a better boiler on the wall.
✅
Proper Communication
We tell you what we’re doing, when we’re doing it, and how long it’ll take. If the job runs over, you’ll know why. We don’t disappear for three hours and hope you won’t notice.
✅
Local and Reliable
We’re based nearby, not in a call centre somewhere else. If you need us after the install, you can actually get hold of us. That matters — especially in the middle of January when your heating goes off.

Is Your Boiler Letting You Down?
Bathwick is one of Bath’s most elegant quarters, just east of the river — think Great Pulteney Street, Sydney Gardens and the grand Georgian townhouses that run up Bathwick Hill, alongside Victorian villas and homes near the Kennet & Avon Canal. Much of it is listed or in the conservation area, and the housing is largely period, solid-walled Bath stone.
Those grand period homes have big rooms and high ceilings and lose heat faster than a modern build, so they need to be sized carefully — a proper heat-loss calculation, not a guess — and flue positioning takes real thought in a listed or conservation-area property. A larger townhouse with more than one bathroom usually suits a system boiler and cylinder; a smaller flat or mews may suit a combi. If you’d like to explore lower-carbon heating, we also fit air source heat pumps.
Bathwick gets Bath’s hard water off the limestone, and scale is one of the main reasons boilers fail early here, so every install includes a full system flush and a scale-reducing filter as standard. You’ll get a fixed price agreed in writing before we start and tidy work from a local Gas Safe engineer. See our main boiler installation in Bath service, or ask about a repair or annual service.
Combi Boilers
The most popular choice for smaller and medium-sized Nailsea homes — especially two and three-bedroom cottages. A combi heats water on demand, so there’s no cylinder taking up space in the airing cupboard and no tank in the loft. Compact, efficient, and straightforward.
System & Regular Boilers
System Boilers — Better suited to larger homes with more than one bathroom. If you’ve got a four or five-bed rural property in Nailsea, a system boiler with a hot water cylinder handles the demand without losing pressure.
Regular Boilers — If you’ve got an older property with a traditional heating setup — gravity-fed system, tanks in the loft — a regular boiler might be the best fit. We see these often in the older stone properties around Nailsea.

We fit boilers from Worcester Bosch and Viessmann — two of the most reliable manufacturers in the UK. Both offer excellent build quality, strong aftercare, and warranties that actually mean something.

We’ll always recommend what’s right for your home — not just the most expensive option.

Can you install a boiler in a listed or Georgian property in Bathwick?
Yes. We’re used to period and listed homes in Bathwick — we plan flue routes and pipework sympathetically and size the boiler with a proper heat-loss calculation so a grand, high-ceilinged property stays warm.

For a larger townhouse with more than one bathroom, a system boiler and cylinder usually beats a combi. For a smaller flat or mews, a combi can be the neat choice. We’ll advise honestly based on your property and hot water demand.
