But the boiler is only as good as the installation: the size, the location, the flue, the pipework and the controls all decide how well it performs for the next decade and more. Warm-Wise installs gas boilers across Nantwich and South Cheshire. Worcester Bosch is our preferred boiler brand, and we recommend the right type and output for your home rather than the biggest one on the list. Our engineers are Gas Safe registered (927370), and because we also handle the electrics and plumbing, the whole installation is completed by one team. Once it's in, we don't just hand you a manual. We walk you through your new controls so you get the comfort and savings you paid for. ### Who it's for - Homes with a boiler that keeps breaking down - Households with an old, inefficient boiler - Anyone converting from a regular to a combi system - Renovations where the boiler needs moving ### Signs you need it - Repeated repairs or parts hard to find - Rising gas bills with no change in use - Not enough hot water for the household - Moving the boiler as part of a new kitchen ## The cost of putting off a boiler replacement An ageing boiler rarely fails at a convenient time. Waiting too long often means an emergency decision in winter, with little time to plan. ### Breakdown in the cold Older boilers are most likely to fail under heavy winter demand, leaving you without heating or hot water while you arrange a replacement. ### Paying to heat the flue Older, less efficient boilers use more gas for the same warmth, so the running costs add up year after year. ### Wrong size, wrong type An oversized or poorly chosen boiler cycles on and off, wears faster and wastes energy. Getting the choice right matters more than the brand. ### Cutting corners on installation Poor flue routing, no system clean or badly set controls can shorten a new boiler's life. We fit it properly and set it up to run efficiently. How it works ## Our boiler installation process - 01 ### Home survey We look at your current system, hot water needs, flue options and where the boiler should go. - 02 ### Recommendation and quote We explain which boiler suits your home and why, then provide a clear written quote. - 03 ### Installation day Old boiler removed, new boiler fitted, pipework and electrics completed by our own team. - 04 ### Commission and test The boiler is commissioned, safety-checked and the system tested for correct operation. - 05 ### Controls walkthrough We show you how to use your new controls, tidy up, and cover the work with our 12-month workmanship guarantee. What you get ## Why choose Warm-Wise for boiler installation ### Reliable heating A new boiler removes the worry of repeated winter breakdowns. ### Lower running costs Correct sizing and set-up means less gas for the same comfort. ### Preferred brand Worcester Bosch is our preferred boiler brand for build quality and parts availability. ### One team Electrics, plumbing and gas all handled in-house, so the job isn't delayed. ### You'll know how to use it We talk you through the controls before we leave. ### Guaranteed workmanship 12-month workmanship guarantee on the installation. ## Boiler types and installation options ### Combi boilers A combi boiler heats water on demand straight from the mains, with no hot water cylinder or loft tanks. It suits most smaller and medium-sized homes and frees up cupboard space. We check your mains water pressure and flow first, because a combi only performs as well as the supply feeding it. ### System and regular boilers Homes with more bathrooms or higher hot water demand often do better with a system boiler and a stored hot water cylinder. Regular (heat-only) boilers suit some older systems with tanks in the loft. We'll tell you honestly whether it's worth converting or keeping your current layout. ### Like-for-like swaps and relocations A like-for-like swap in the same position is usually the quickest and least disruptive option. If you're refitting a kitchen, we can move the boiler to a cupboard or another room, reroute the pipework and flue, and complete the electrics in the same project. ### Controls and system protection We pair new boilers with sensible controls and advise on protecting the system, so the new boiler isn't working against years of sludge in the old pipework. ### Monthly payment options At Warm-Wise we know your boiler is at the heart of your home, and the cost of replacing it can sometimes come as a surprise. It's not something that many of us save for, or something we want to spend our savings on.
