FREQUENTLY ASKED QUESTIONS
WHAT IS A THERMOSTATIC RADIATOR VALVE (TRV)?
Ideally, TRVs should be well exposed and not obstructed by curtains or blocked by furniture.
SHOULD I HAVE MY HEATING SYSTEM TREATED OR CLEANSED?
It is best practice to cleanse an existing heating system prior to installation of the new boiler. After the boiler has been installed, the heating system should be cleansed of debris and refilled with inhibitor.
Your chosen boiler installer should be fully conversant with all current standards/regulations relating to this part of the installation.
WHAT SORT OF SHOWER CAN I RUN OFF COMBI BOILER?
In contrast, when a regular boiler and cylinder is replaced with a combi boiler, any existing shower should be examined for suitability. This might be a pump assisted power shower, for example, designed for low-pressure systems.
Please seek specialist advice from your boiler installer on the correct shower selection.
HOW OFTEN SHOULD I NEED TO TOP UP THE PRESSURE IN THE HEATING SYSTEM?
Note: The red part of the dial could also indicate the pressure being too high (about 2.75 bar or more). If the pressure gauge indicates high pressure as a result of over filling, you will need to bleed a radiator until the pressure gauge returns between 1 and 1.5 bar.
If pressure rises by more than 1 bar when the heating is up to temperature then the expansion vessel may require repressurising. This will require a service engineer.
The pressure in the system will usually require topping up once or twice a year. If you are having to repressurise your heating system much more frequently, please contact your installer.
SHOULD I REPAIR OR REPLACE MY OLD BOILER?
A brand new boiler is usually more efficient and more reliable. Your new boiler will be covered by warranty too – so if it breaks, the manufacturer will repair it with no extra charge. At the end of the day it is 100% your choice!
WHAT IS A FLUE?
Flues can either be square or round in shape. If the flue is less than two metres off the ground, or underneath a carport or shelter, it’ll be covered by a guard. This looks like a piece of wire mesh covering the end of the flue.
When you buy a boiler from WWG, we’ll also supply and fit a brand new flue for you, along with all the safety attachments you need.
HOW DO I KEEP MY BOILER WARRANTY VALID?
We will contact you at the beginning of the month when your service is due to expire, so you have lots of notice and time to get this booked in.
