Heating problems should be sorted in summer

09 July 2015

Heating problems can arise at any time and although summer is the last time you’ll  think of your heating system, it is in fact the best time to have it looked at. No one wants to start a cold winter realising they have heating problems. Having a qualified heating engineer to regularly service your central heating system is the best way to avoid breakdowns.

Read on for some signs that could point to heating problems…

Heating clicks on and off at the wrong time

Thermostats, electronic programmers and time switches should be set to provide the optimum heat when you need it. If the boiler switches itself on or off at incorrect times, or your home feels unusually hot or cold, the first things to check will be the controls.

It could be that a room or radiator thermostat has been accidentally changed, or you may have a time switch that needs to be re-set when the clocks change for British Summer Time. Both these heating problems are simple to fix by just correcting the temperature or time.

A time switch with a mechanical clock dial should be checked in case it is stuck, and an LCD display on an electronic programmer should be checked to ensure it’s showing the correct information. If a fault in either of these has developed they are easily replaceable.

Old thermostats should also be replaced if they don’t seem to be controlling temperatures properly, which can happen with age.

 

Cold spots in radiators

If the top part of a radiator is cold but the rest is hot the likely cause is trapped air inside. To release the trapped air you will need to turn off the heating first and then use a radiator key to slightly open the bleed valve on the radiator. When you do this you will hear a hiss as the air escapes but will need to be ready to close the valve again quickly before any water escapes. Lay an old towel under the valve or a paint tray to catch any escaped water.

Cold spots in the middle or bottom of radiators can be more difficult heating problems to fix, as they usually indicate a build-up of scale or rust that is stopping the normal flow of hot water. If you have an open-vented system you can try a chemical scale remover that is added to the feed and expansion tank. Your system will then have to be emptied and refilled after the chemicals have worked.

If more than one radiator in your home is affected it could be beneficial to ask a professional heating engineer to power flush your whole system. This consists of using a special pump to wash out all radiators and pipes with fast moving but low-pressure water. This will effectively remove any sludge without causing any damage.

 

Strange noises

Don’t ignore strange noises in your heating system – rattles, bangs and hisses are often easy to fix faults. You should, however, always try to locate the source of a new noise, as it could indicate serious heating problems. Noises coming from the boiler could point to a build-up of scale, problems with water flow or pressure, or a faulty thermostat allowing the water to overheat. If in doubt, call a professional Gas Safe registered engineer to check your heating, if it is powered by gas.

    5 star review  Absolutely brilliant service by Homecure. We have had an ongoing issue with our troublesome boiler for a few months now. We have had several companies in over that time but no one had seemed to solve the issue with many people advising to change the boiler even though it wasn’t even 10 years old. We thought we would give Homecure a try after a family friend had recommended them and all I can say is they were fantastic. The engineer who came (I think his name was James) was able to find out what the issue was within 30 minutes, he also explained why it was most likely the other engineers didn’t find the issue. I can only put this down to some serious expertise on his part. A new part was ordered and a return visit booked for the next day and everything was restored and working perfectly again. The prices were definitely reasonable for the experience and expert knowledge received, I would say you definitely get what you pay for. I only wish I found Homecure Plumbing earlier. Needless to say I would highly recommend and will definitely be using again. Regards David H
