Winter boiler problems in Brighton & Hove: what to check first
If you wake up to a cold house, try the hot tap before you reset the boiler. A combi boiler that still runs a hot shower but leaves every radiator cold gives us a different starting point from one that’s stopped doing both. Here’s what you can check at home and when to get a heating engineer involved.
If you smell gas, leave the property and call the National Gas Emergency Service on 0800 111 999 from outside. Avoid flames and electrical switches. If your carbon monoxide alarm sounds, get everyone into fresh air and call the same number. SGN gas emergency guidance
Why has my boiler stopped working after a frost?
If the heating and hot water both went off overnight, the boiler is gurgling and temperatures have been below freezing, a frozen condensate pipe is one possibility. This plastic pipe carries water away from a condensing boiler. Where it runs outside to a drain, ice can block it and cause the boiler to shut down.
If you can identify the pipe and reach it safely from ground level, gently pour warm water over the frozen section. Never use boiling water. Watch where the water runs because it can freeze on the path. Once the pipe is clear, follow the reset instructions for your model. If the fault returns, take a photo of the code and contact an engineer. Worcester Bosch guide to frozen condensate pipes
Why does my boiler keep losing pressure?
On a sealed heating system, check the pressure when the radiators are cold. Around 1 to 1.5 bar is typical, but use the figure in your boiler manual. If the reading is low and the manual gives a homeowner top-up procedure, follow it and close the filling valves fully afterwards.
If the pressure drops again within days, tell us how quickly it fell. A damp patch beneath a radiator valve or a reading that climbs sharply when the heating comes on are both worth mentioning. A photo of the gauge when cold and another when hot can help us work out where to start. Worcester Bosch boiler pressure guidance
Why do I have hot water but no heating?
If your combi still heats the taps, check what the room thermostat is asking the boiler to do. Is the heating schedule on? Is the target temperature higher than the temperature in the room? If a wireless thermostat has a blank screen, check its batteries. Turn the target up briefly and see whether the boiler responds.
If every radiator stays cold, tell the engineer that the hot water still works. If just one radiator is cold, check that its thermostatic valve is open and see whether the radiator is cold all over or only at the top. That small detail helps narrow down the fault.
Why is my combi shower cooler in winter?
Mains water comes into the house colder in winter. A combi has to raise its temperature further, so a fast-running bath tap or shower can feel cooler than it did in summer. Try reducing the flow slightly. If the water settles at a comfortable temperature, the flow rate may explain the change.
If the shower repeatedly swings from hot to cold, try the basin tap on its own. Does it do the same thing? Tell us whether it happens at one outlet or throughout the house. It’s a useful way to distinguish a shower problem from one that needs a boiler visit.
