Locally, this is what comes up

Boiler installation in Harrow

  • Bathrooms in loft conversions that the system was never sized to serve
  • Radiators tacked onto the existing circuit for rear extensions
  • Homes now on a third heating system, with pipes remaining from all three

Harrow’s semis are close together, with a narrow side passage between each pair. A flue terminal on that side wall ends up near the neighbour’s windows and the boundary, which limits where it can go and sometimes means a plume kit or a move to the rear wall. Many of these houses still store hot water in a copper cylinder in the airing cupboard, often with an immersion heater as backup. Heating systems on their third boiler usually carry a mix of old steel and newer copper, and that mix produces sludge. A thorough flush and a magnetic filter protect the new boiler from what the old pipework sheds. Front drives make delivery straightforward on most streets. Building control is notified by the Gas Safe engineer when the job is finished, and the compliance certificate arrives by post.

Questions

Questions we often get

Do you work in Harrow?

We do. Harrow falls within Harrow, covering the HA1, HA2, HA3, HA5 postcodes, and our engineers are out across Greater London from our Fulham office every day.

Our top floor is cold all the time. Would a new boiler solve that?

Only when the boiler is at fault, and with a loft conversion it frequently is not. Usually either the system was not resized for the added radiators, or the circuit needs balancing. We prefer to find that out first rather than sell you a boiler that makes no difference.

We rely on the immersion heater when the boiler breaks down. Would we lose that with a combi?

Yes. A combi heats water as you use it, so there is no cylinder and no immersion heater to fall back on. If the boiler fails, you have no hot water until it is fixed. A system boiler with a cylinder keeps the immersion as a backup, at the cost of the airing cupboard space. For a household that has come to depend on that backup, it is a real reason to keep a cylinder.

How much will it cost?

Before an engineer starts, you are given a price for the job. Should something hidden in a wall change what is needed, we stop and discuss it with you first, instead of pressing on and sending the bill later.
