Heating that suits the house runs low and steady and keeps the rooms warm. To get there, the system has to match the heat your house loses, room by room, on a cold day. The survey gives us that figure, and the rest of the design follows from it. - **Survey the house**: We measure each room and record the walls, windows, loft and floor insulation and ventilation, along with your existing radiators and pipework. - **Work out the heat loss**: Each room gets its own heat loss figure. Added together, they tell us what the system has to deliver on the coldest days. - **Design the system**: We do the heating design ourselves: flow temperature, radiators, pipe sizes, hot water cylinder and controls. If a radiator needs to change, we'll show you which one and why before you decide. - **Install and hand over**: The system is set up to the design, and we take you through the controls before we leave. ## What the survey covers Every room measured Walls, windows and insulation recorded Ventilation checked Existing radiators and pipework assessed How you use your heating and hot water ## What you get at handover A system sized to your house's heat loss Radiators checked against the design and changed only where needed The system set up to the design A walk through the controls A tidy house, with dust sheets down throughout the job ## A new boiler, chosen for your house Replacing a boiler is a good moment to look at the rest of the system too. We check the whole set-up before we recommend anything, so the boiler you get suits the house and the hot water you need. ## How the job runs We come out, look at your existing boiler, pipework and controls, and talk through what you want from the new system. Then you get a free quote. On the day, dust sheets go down, the old boiler comes out and the new one goes in. We clear up before we leave and make sure you're comfortable with the controls. ## Combi, system or regular The right type depends on the house, the number of bathrooms and how much hot water you use at once. We explain the options in plain terms and recommend one. The choice stays yours. ## Who does the gas work We take the enquiry and manage the job from start to finish.
