Few things are more stressful than a boiler breakdown — especially during a cold London morning.
Before you panic and reach for the phone, there are a few safe and simple checks you can do that may resolve the issue quickly.
At Hippo Heating and Electric Services, we believe in empowering homeowners to understand their systems while providing fast, reliable boiler repair services across London, Greater London, West London, and surrounding areas.
💡 Step 1: Check the Thermostat
This may seem basic, but many ‘boiler problems’ are caused by incorrect thermostat settings.
Make sure the thermostat is turned on, set to heating mode, and the temperature is higher than the current room temperature.
If it’s a wireless thermostat, check the batteries and make sure it’s communicating with the boiler.
🔁 Step 2: Try Resetting the Boiler
Modern boilers often have a reset button.
Consult your boiler’s manual to locate and safely use it.
Resetting the boiler can clear minor internal faults — but if the issue persists or comes back quickly, professional help is required.
⚙️ Step 3: Check the Boiler Pressure
Your boiler pressure should typically be between 1 and 1.5 bar when cold.
If it drops below this level, the boiler may lock out as a safety measure.
You can top up the pressure using the filling loop — usually located underneath the boiler.
Refer to your manual or contact us if you’re unsure how.
❗ Step 4: Look for Error Codes or Warning Lights
Most digital boilers show an error code if something’s wrong.
Write it down — it can help our engineers diagnose the issue more quickly.
Common codes may relate to:
-
Low pressure
-
Ignition failure
-
Sensor faults
🔥 Step 5: Bleed Your Radiators
If radiators are cold at the top but hot at the bottom, there may be trapped air in the system.
Bleeding your radiators using a radiator key can improve efficiency and reduce strain on the boiler.
