Boilers & Heating FAQ's

 

Replacing your Gas Boiler

 

Your gas boiler is the backbone of your heating system and as such you need to make sure that it is as efficient as possible. Modern condensing boilers are much more efficient than their older counterparts. Having a modern boiler in your home will maximise the efficiency of your heating system and dramatically reduce your energy bills.

 

By upgrading your old gas and heating controls you will make sure that your heating system is efficient and you can take advantage of all the savings that can be made. So if you’re in need of a new boiler, let us know. We have great offers on Vokera Boilers and Worchester Bossch boilers.

 

If you are worried about your boiler get in touch with us today and we can talk you through all the various options we have available here at Churchfield Home services. 

 

 

How often do I need to service my boiler?

 

Your boiler needs an annual service visit to check that it is operating correctly and safely. The service must be done annually or the manufacturer’s warranty will be void.

  

How do I know when to bleed my Radiators?

 

You will need to bleed your Radiators when you find they are cold at the top and hot at the bottom. If you have a sealed system you will need to ensure the system water pressure is reset after bleeding. Warning – be careful not to over tighten the radiator bleed screw after bleeding the air out.

 

 

What do you mean by ‘Condensing’?

 

A condensing boiler recovers a much heat as possible from the flue gases, this energy would normally be wasted with a conventional (non condensing) boiler.

   

Why is water from my Combination boiler cloudy?

 

Combination boilers heat mains water directly as required. During this process the Calcium Bi-Carbonate changes to Calcium Carbonate, this creates carbon dioxide which is millions of tiny bubbles, this gives the water the cloudy effect. Once the water settles and cools it begins to clear, this reaction is more apparent in hard water areas and from boilers with a slower flow rate. This occurrence is purely cosmetic.

 

I have 1 radiator that is not working?

 

This could be due to your radiator needing bleeding (see note above) or it could be due to the thermostatic radiator valve (TRV) that is shut down too low. Try turning your TRV fully open and ensure there is a demand on from your clock/programmer and room thermostat.

 

My Radiators are not working?

 

Check there is a demand from the clock/programmer (ensure the settings are correct) and also check that the room thermostat is calling for a demand. You may need to refer to the manufacturers user instructions. Dependant on your installation you may have a combined Clock/programmer and Thermostat or they may be separate.
