Gas engineer in London

There are four major types of boilers:

1. Combination boiler:
   Combination or combi boilers are usually compact with 4-5 copper pipes connected at the bottom. It is not attached to any external pump or large hot water cylinder.
2. System boiler:
   You can identify a system boiler by checking underneath. It usually comprises three copper pipes rather than the 5 in a combi. Besides, some also come with a hot water cylinder. You can see a pressure gauge at the front of the casing.
3. Heat-only boiler: 
   Also known as a regular boiler, it has three copper pipes. Two at the top and one at the bottom. This is usually with a hot water cylinder, a cold water storage tank, and an external pump.
4. Back boiler:
   Using old back boilers is not allowed in the UK unless you update them. Back boilers are often installed at the back of a gas fire.

All the above boilers (excluding back boilers) are available in condensing and non-condensing variants.

Generally, all boilers installed in England are now condensing given their high efficiency and cost-friendliness.

Boilers hold extreme pressure, flammable gas and high temperature, making them unsafe for DIY diagnosis. We don’t recommend you attempt to do any work on your boiler. You can only legally service a boiler on your own if you’re trained, competent, and accredited by Gas Safe.  If your gas boiler breaks down, make sure you reach out to a Gas Safe and accredited engineer.

Some work like re-pressurizing, resetting, bleeding air out from radiators, or changing thermostat batteries can be done by you. We would always recommend you call a professional plumbing and heating engineer instead of risking your safety. Most jobs need specialist tools, like a power flushing machine, radiator valves, or a thermal camera to view cold spots.

All gas appliances, including boilers, must be inspected at least once a year. You can flush a central heating system using two methods; power flush or clean each radiator individually.

A power flush is the fastest way to remove sludge and offer the best results.

Radiator cleaning is a time-consuming process. You’ll need to turn off the heating system, to avoid leaks or injury.

The costs of a radiator power flush can vary depending on the number of radiators, and the complexity of the model. Call the Fixcrowd team If you want to know how much a power flush or gas certificate will cost.

Gas Safety Certificate checks vary between £50 to £160 depending on the number of appliances you’re using. The engineer has to check your boiler for repair or replacement. The additional boiler servicing cost may add up to your main cost.
