Is your storage heater failing to retain warmth through the night? Before you call an engineer, ask yourself three quick questions: Is the heater properly insulated? Are the input/output controls set correctly? Has the thermal brick core degraded? With just a few basic tools, you can diagnose and often resolve this issue yourself. Understanding Your Storage Heater Storage heaters work by absorbing electricity during off-peak hours (usually overnight) and releasing stored heat gradually throughout the day. The core components – thermal bricks, insulation, and damper controls – must function in harmony. When heat retention fails, it's typically due to either heat escaping too quickly or insufficient energy being stored initially. Diagnosis Table Symptom Probable Cause Solution Heater cools by mid-morning Damper control stuck open Clean and lubricate damper mechanism Heater never gets properly warm Faulty input thermostat ...

Is your radiator making gurgling noises? Are certain sections cold while others remain hot? Before you call a plumber, ask yourself three quick questions: Is your heating system turned off?

Over time, air can accumulate inside the radiator, creating cold spots and reducing performance. Bleeding releases trapped air, allowing water to flow freely. A radiator key is the specialised tool designed to open the bleed valve safely without damaging the valve’s square nut. Symptom Probable Cause Solution Cold patche...
