New boiler installation in Tile Hill, Coventry. Swapping back boilers and first-generation combis on the estates, with the pipework and controls done properly.
A swap in a house like that is more than lifting one boiler out and hanging another. A back boiler removal leaves a hole in the chimney breast and a hearth to make good. The gas supply pipe fitted in 1962 is often too small for a modern boiler, so it needs upgrading from the meter. And the old radiators and pipework have years of sludge in them, which will wreck a new heat exchanger if the system is not cleaned first.
So the questions worth asking before anyone quotes are: where is the new boiler going, does the gas supply need upsizing, how is the system being cleaned, and what happens to the chimney and the old flue. A survey answers all four. Photos of the current boiler, the meter and the radiators get you most of the way there. If you smell gas, leave the house, do not touch switches and ring the National Gas Emergency line on 0800 111 999 from outside.
Taken out properly, the chimney sealed or lined as needed, and the fireplace left ready for the plasterer or made good, not left as a hole with a board over it.
Many Tile Hill houses have a 15mm supply from the meter. A modern boiler usually wants 22mm, and skipping that is why some new boilers lock out on cold mornings.
A flush and a magnetic filter before the new boiler runs, so the sludge from the old radiators does not end up in the new heat exchanger.
Kitchen cupboard, utility or upstairs: the flue route, the condensate run and the noise all change with it, and it is worth deciding before the work starts, not on the day.
A simple programmer and room thermostat, or a smart control if you want one. Set up and explained before we leave.
A straight swap is usually a day. A back boiler removal with a gas upgrade is two or three, and you will be told which it is before it starts.
Yes. The boiler comes out, the chimney is dealt with, and the opening can stay as a fireplace or be closed up neatly. It is worth deciding before the work so the making-good is planned.
Often in these houses, yes. The pipe from the meter is checked as part of the survey, because a modern boiler starved of gas will lock out no matter how good it is.
Not always. Old radiators that flush clean are usually fine. The ones that come back cold at the bottom after a flush are the ones worth changing.
Usually one working day for a straight swap, longer where a back boiler comes out. We try to leave hot water on the same day wherever the system allows.
It comes down to bathrooms and how many people want hot water at once. A three-bed Tile Hill semi with one bathroom is usually a combi; two bathrooms often is not.
