Heating Genie has a simple guide to assist homeowners in diagnosing their appliance problems without having to pick up the phone. Often a breakdown visit can be averted by following some simple steps. This also gives us vital information should a visit by our Engineer be required.  

Below is a simple 4 step guide that homeowners can carry out before calling us:

power

1. Check you have power

fuel

2. Check you have fuel

water

3. Check you have water

controls

4. Check the controls

Should your boiler still not operate then have a look at the other common problems to see if your boiler shows any of these symptoms or give us a call on:

10 common boiler/system problems 

1. No heat or hot water – This tends to happen at the most inconvenient time, finding that your boiler isn’t producing any heat or hot water is actually a common problem if not annually maintained correctly.  

2. Leaks – a variety of issues can cause your boiler or system to leak water. Any obvious leaks need to be addressed as soon as possible to ensure that further problems don’t arise. 

3. Noises – Heating systems can emit strange noises, be it banging, whistling or gurgling sounds. Numerous things can be attributed to the problem, air in the system, water pressure too low or the common sound of kettling usually due to scale or sludge deposits. 

4. Pilot light extinguishing – Although these style of boilers are reducing due to more modern efficient appliances, the most common cause is the thermocouple. If the thermocouple fails then the gas supply to the pilot light is extinguished. This may need to be replaced. It could also be down to a draught blowing the pilot light out, broken seal or a build up within the pilot light. Its also worth checking other gas appliances to make sure the gas is turned on.  

5. Losing pressure – This could be simply down to a leaking valve, radiator, pipe or the pressure relief valve (sealed system), which in turn is caused by the expansion vessel failing or losing pressure. This problem can be rectified by replacing the pressure relief valve and recharging/replacing the expansion vessel. A sealed system usually has between 1 – 1.5 bar of pressure when the system is cold and rises at the system heats up. 

6. Frozen condensate pipe – modern energy efficient boilers have a condensate pipe. This transports water away from the boiler and can freeze up (where exposed externally) during prolonged periods of extremely cold and icy weather. During these extreme conditions the pipe blocks with a slug of ice. Thawing a frozen condensate pipe should ideally be done by a qualified engineer, but it is possible to defrost the pipe using a hot water bottle or hot water over the end of the pipe. Care should be observed using hot water. 

7. Thermostats – the older a thermostat the more likely it is to develop a fault, whether it’s misreading temperature settings, losing accuracy or turning the heating on/off when it’s not supposed to. There is now a minefield of new thermostats available whether mechanical or digital and remember the correct location of the thermostat is detrimental to the operation of the system. 

8. Kettling - kettling is caused when deposits builds up on your boiler’s heat exchanger. If you start to hear a strange rumbling noise, it could be due to kettling. Lime scale/sludge can result in steam bubbles being produced which can be responsible for the banging noise just like when you switch on your kettle.  

9. Radiators - not getting hot when the central heating system is on – this could be simply down to a failing circulating pump. Alternatively it could be due to an incorrectly piped system or a build up of sludge. The sludge can prevent the free flow of water to the radiators. Chemically cleaning or flushing the system will remove these deposits. We would also recommend the fitting of a Magnaclean system filter to assist in the removal of system debris. 

10. Boiler locking out - numerous issues already mentioned could explain this, from low water pressure (check the gauge to make sure the pressure is correct), to a problem with the thermostat and a lack of water flow due to a closed valve, air or the pump not circulating the water in the system properly. 

  

 

It is great to have found a plumber who I can trust and who responds quickly.

They have replaced boilers for me, sorted out big and small plumbing problems

With rental properties in York, Beverley and sutton on Derwent it's really useful to have reliabe help at hand particularly when we live so far away.
