New Boiler Reading: Gas Safe Installation Quotes

Terraces and semis make up more than half of Reading's homes, with flats about a third. That split drives the boiler choice: combis suit most flats and smaller terraces, while larger semis with two bathrooms often need stored hot water.

Whatever type you choose, Reading's hard water needs planning for at the install.

Combi, system or regular

A combi heats water on demand and needs no tanks. It suits homes with one bathroom and decent mains pressure. A system boiler with an unvented cylinder runs two showers at once and is the usual choice for larger semis.

A regular boiler with loft tanks is still right in a few homes, for example where mains pressure is low. Ask the installer to measure flow at the kitchen tap before recommending anything.

Fitting for hard water

Reading gets its water from Thames Water, and the supply is hard or very hard. Ask for a scale reducer on the cold main to a combi, a magnetic filter on the heating return, a system flush and fresh inhibitor. Many manufacturers make these conditions of their longest warranties.

Ask the installer to set the hot water temperature on a combi no higher than you need; scale forms faster at higher temperatures.

Boilers for Reading homes

Victorian brick terraces in the town's older streets

Two-up two-down terraces usually suit a combi in the kitchen. Terraces with a loft conversion and second bathroom may need a system boiler.

Interwar and post-war semis in the suburbs

Semis with an airing cupboard can keep a cylinder, which also makes a future heat pump easier.

Estates and apartments built from the 1970s onwards

Flats from the 1970s onwards may have electric heating. Adding a gas boiler where there's no gas supply is rarely worth it.

Areas covered

Engineers who cover Reading work across areas including Caversham, Tilehurst, Earley, Woodley, Whitley, Emmer Green, Lower Earley, Southcote, Calcot and Theale.

Questions people in Reading ask

Is a heat pump worth pricing alongside a Reading boiler quote?

If you have a garden and space for a cylinder, yes. The national grant takes £7,500 off, and Reading's local grant may cover more for eligible households.

How long does it take?

A combi swap is usually one day; changing system type takes longer.
