Your Boiler’s Heating Water, Not Your Home | London News

Your combi boiler might be secretly heating your home even when the central heating’s off—turning every shower and dishwashing into an energy drain. Engineer Patrick Garner reveals how hot water cycles add up, hiking your bills and making your place feel like a sauna. Fix it by switching to “hot water only,” dialing temps to 45–50°C, ditching “pre-heat” modes, batching hot water use, and sealing leaks. (Note: If you’ve got a hot water cylinder, keep temps above 60°C to avoid Legionella.) Small tweaks = big savings.
