Stay warm, stay informed
As temperatures drop, your heating system becomes the unsung hero of your home. But when things go wrong, comfort disappears fast. Here are five of the most common heating issues — and how Gosai Heating & Gas can help.
1. Cold radiators
Usually caused by trapped air or sludge buildup. Bleeding the radiators can help, but if the problem persists, you may need a power flush.
2. Low boiler pressure
Low pressure reduces heating performance. Check your gauge — it should read around 1–1.5 bar. If it keeps dropping, there may be a leak.
3. Noisy boiler or pipes
Whistling or banging could mean limescale buildup (kettling) or trapped air. These are early signs your boiler may need servicing.
4. Uneven heating
Some rooms hot, others cold? Your system may need balancing or thermostat adjustments.
5. Heating won’t turn on
Could be a faulty thermostat, power supply issue, or frozen condensate pipe — all best checked by a qualified engineer.
Don’t ignore the signs.
At Gosai Heating & Gas, our engineers are available across London to diagnose and repair heating faults quickly — keeping your home safe and warm.
