No hot water in Gloucester? Here's what to do.
No hot water is one of the most common winter callouts. The cause is usually one of three things — and two of them you can try to fix yourself before paying anyone.
Try this first
Safe steps you can take in the next 10 minutes — in order.
- 1Check the boiler pressure gauge. If under 1 bar, repressurise via the filling loop to 1.2 bar (manual is in the boiler's manufacturer paperwork).
- 2If the boiler shows a fault code, search the manufacturer's app or website with that exact code.
- 3In freezing weather, gently pour warm (not boiling) water over the condensate pipe outside until the boiler restarts.
- 4Reset the boiler once via its reset button. Do not reset more than twice in a row.
When to stop and call
If repressurising, defrosting, or resetting doesn't restore hot water within an hour, stop and call a Gas Safe engineer. Repeated resets can damage the PCB.
Likely causes
Most cases of no hot water in Gloucester homes come down to one of these.
- Boiler pressure dropped below 1 bar — combi boilers will lock out
- Pilot light out (older non-condensing boilers)
- Diverter valve stuck (boiler heats radiators but not water)
- Frozen condensate pipe in winter (white plastic pipe outside, often blocked between November and February)
- Power supply tripped at the consumer unit
