One of the biggest downfall for heating systems is the quality of water in your system.

If the water in your system has never been treated or flushed out, it is probably contaminated with rust, lime scale and debris, and needs a power flush or magna flush.

Also we can now attach a filter to your system by means of installation of a magna clean, this will stop any magnetite, which is the steel that rots on the inside of your radiators, entering your boiler.

This is a must to have fitted and protect your boiler.

Clunking and banging noises are called ‘kettling’ noises, and are caused when limescale accumulates on the heat exchanger.

This blocks the flow of water and causes some water to boil, steam and expand, as seen in a kettle.

Although modern boilers are full of innovative safety devices that should minimise the likelihood of kettling causing your boiler to boil up, such as pressure relief valves, this problem will significantly reduce the efficiency of your boiler and will cause internal damage in the long-term.

Gurgling noises within a gas boiler may also be caused by air in the system, a blockage or sediment at the bottom of the boiler. Gurgling may also be caused by a frozen condensate pipe, and this pipe will need to be thawed. If you know what you’re doing, you can thaw a condensate pipe with hot water bottles and heat wraps, but you should only do so if the pipe is easily accessible and is at ground level.

1, Check your programmer is set to on, on the hot water switch

2, Check you pressure in your boiler

3, If a conventional system, (with a cylinder fitted) not a combi, check your outlet on the taps, as even though your boiler is not firing, you may already have tank full of hot water.

A gravity hot water recirculation loop works by allowing the laws of nature to come into play. Hot water tends to rise while cold water tends to descend at the bottom of a contained space.

Your boiler is switched on, hot water only. The boiler will then heat the water inside the heat exchanger, this will the rise up the circs (flow & return) and the cold water will drop back into the boiler. This will indeed heat the water stored in your cylinder, this process will continue until the temperature stat on the cylinder is up to temperature. See picture

Here are a 5 simple checks to assess whether it is your boiler or a supply issue.

1, Turn on any related gas appliance, this will confirm you have gas running through the property.

2, Check any controls are turned on, programmer on constant, room thermostat is calling for heat, to make sure it is turn it up to 30 degrees for a short period and watch to see if the boiler fires up.

3, Check the pilot light on the boiler, if indeed it has a pilot light, a lot of new boilers nowadays are electronic ignition, and do not have a pilot light.

4, Check your boilers manufacturer’s instructions, if showing a fault code, confirm what the code means in the book before calling out an engineer.

5,Check your pressure in the boiler, is it reading the correct reading as advised in the manufacturer’s instructions? If not adjust and reset the boiler and test again.

Always remember a boiler needs 3 things in order to work, fuel(gas), electric, and water, if it’s still not working call us on 0333 313 3134

Smell Gas?

National Gas Emergency Service
24 hours a day on
0800 111 999
(calls are recorded and may be monitored).

Open doors and windows.
Ventilate the property.
Turning the gas off at the meter unless the meter is located in the cellar/basement.
Avoid the use of any naked flames or electrical switches.

Please follow the procedure above, once the emergency service has been out please call us to rectify the issue on 0333 313 3134.
