Emergency boiler repair

24/7 Boiler Breakdown Service, Waterloo, London

Boiler breakdowns can be real pain in the neck. Especially in the winter time when everyone needs their house heating. Coupled with a lack of running hot water, you’ll need someone with you rapid to fix the situation and get that house nice and warm again.


Whats causing my boiler problems?

Well in short it could be a one of a number of issues. Typically boiler problems can occur when the system has not been used over the summer months.

Let us outline a couple of common faults below

It’s worth mentioning at this stage, if you’re unsure, of what’s causing the issue, it’s always best to call a gas engineer professional and not try and remedy the issue yourself as you could cause further issues with the boiler or, worse, danger those around you. Gas boilers should only be worked on by a trained professional.

1. Banging or whistling boiler

 A noisy boiler is typically the sign the fan could be on it’s way out, or there is air in the system. Sometimes low pressure can cause noises too. Having noisy boiler is understandably frustrating, especially if the boiler is housed in a bed room.

2. Frozen condensate pipes

In the winter months having a frozen condensate pipe is a common problem.

Most boiler are condensing boiler which means small particles of waste gas turns to water when it cools. Boilers can be defrosted, for more information on defrosting a boiler
condensate pipe check our this handy video, from Worcester Boch.

3. Heating & hot water intermittently comes on and off

Having intermittent heating and hot water is a pain especially in the colder months. 

Typically there are a handful of issues associated with this complaint:

  • Damaged diaphram
  • Air lock issues
  • Faulty motorised valves
  • Broken thermostats

With this boiler issue, it’s advisable to give us call, as this would require a skilled gas engineer to remedy.

4. Faulty pilot light

A common complaint, but if the pilot light is out, that means the boiler isn’t working. The pilot light is found on the underside of the boiler. It could highlight issues with the gas supply. This needs a gas engineer to come out to fix. Please don’t tamper with your own gas supply.

5. Low boiler pressure

Having low boiler pressure can cause the heating and hot water to fail. Our advice would be to check all the radiators and visible pipe works for leaks. If there is is leak it’s time to give us a call. If you don’t find a leak, you can try to re pressurise the system yourself.:
  • Switch off your boiler and allow it to cool
  • Find the filling loop and check that both ends are securely attached. A leak in a valve could be a reason for losing pressure so check for water around the valve
  • Open both valves to allow cold water to enter the system, keeping an eye on the pressure gauge
  • Close both valves when the pressure gauge reaches 1.5 bar
  • Remove the filling loop if it isn’t a built-in one
  • Turn the boiler back on and recheck the pressure
