Does a boiler need to have regular services?
We recommend that you have your boiler serviced each year. This will ensure that it is working at maximum performance and safety.
Why is my radiator hot at the top and cold at the bottom?
This usually means you have a sludge build up in the bottom of the radiator. This can be resolved by powerflushing the system. However, before
taking any action we recommend that you seek expert advice to identify the cause of the sludge first, for example you may have a water leak.
Why is my radiator cold at the top and hot at the bottom?
This usually means that there is air trapped in the top of your radiator. You may want to try to bleed the radiator to release the air. However, we suggest that you have your central heating checked by an expert in case there are any underlying system problems.
Why are some of my radiators hotter than others?
This usually means that your central heating system is incorrectly balanced. This results in the hot water not flowing evenly to each radiator. We suggest that you have an expert check your central heating system.
Why do I not get enough hot water from my combination boiler?
Older combination boilers often have a lower flow rate than newer models. This can be made worse by a build up of scale in the boiler over time.
In this situation we suggest that you have an expert check your boiler and central heating system.
What is a Thermostatic Radiator Valve?
A Thermostatic Radiator Valve allows you to control the temperature in individual rooms around your home. It can also help you reduce your
fuel bills by automatically adjusting the radiator temperature once your room has reached its desired level.

you have in your home and the type of boiler you have fitted.We offer free site surveys where we can assess your requirements and give you a

Isn't fitting a new central heating system very disruptive amd messy?

in your home is kept to a minimum, we will keep you updated on our progress at all times.

What is Benchmark?
Benchmark is an initiative launched to improve quality within the heating industry. All competent heating installers should be aware of benchmark standards. Virtually every boiler sold in the uk comes with its own log book which should be fully completed by the installer and handed to you
once your new boiler has been installed and commissioned. This log book becomes your certificate of compliance with all relevent building
regulations and also is your guarentee. No certificate no guarentee.
Do DAVIES Plumbing and Heating install to benchmark standards?
Yes is the quick answer, but in addition to this all our engineers are continually being re-trained to encompass the changes that will be taking
place in the central heating industry over the next year.
What changes are taking place with regards to my central heating installation?
Quite a few changes will be taking place over the next 12 months, being corgi registered alone won't be enough. Planning permission for boiler
and central heating installation will be required unless;
1) The company installing your central heating can self certify the installation.
2) Corgi will be notified of every boiler and central heating installation in England.
3) Corgi will send a certificate of compliance to you and also inform the building control body (the council).
What if I don't comply and use a non registered installer?
1) In 2006 the goverment are bringing in an home buyers pack to put all responsability on the seller of the house to provide certificates ensuring
gas and electric services all comply with current regulations and standards.
2) All boiler manufactures will not provide warrenty if the home owner does not have their letter of compliance from Corgi.
3) The installation may also be unsafe.
