Excelent customer service and efficient work. Areef managed to get a plumber to visit my residence in about 30 minutes for an emergency work, and kept me updated all the way through in regard to the service being done. The plumber attending my address was also very friendly and professional. I would highly recommend Fixcrowd services.

Heating & Gas FAQs

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.

Call Fixcrowd to book a nearby boiler repair in London. You’ll need to arrange a gas-safe registered engineer when:

  • There is no heat at all
  • There is water leakage
  • Strange noises are coming from your boiler
  • The pilot light is off
  • The water pressure drops below the standard level
  • Radiators are not heating properly
  • There is sludge in the system
  • You can’t use your underfloor heating system

 

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.

Get in touch with our team for the cost of the gas safety certificate today.

Boiler installations can be complex and depend on a few factors. Swapping a like-for-like combination boiler with another combi unit takes a Fixcrowd gas service engineer a few hours.

Installing a new boiler from scratch can take a day on average or two in some cases.

Fixcrowd can help you book same-day boiler repairs in London, including underfloor heating service, installation, and maintenance for residential, commercial and investment properties.

 

Landlords must provide gas safety certificates to their tenants every 12 months. You can book an urgent annual gas safety check today. Call us or book online for availability.

Note:  Homeowners don’t have to renew their gas certificates annually unless they offer lodging services. However, we recommend you get your gas safety checks annually for personal and environmental safety. You can contact your local authorities for any compliance questions.

You also need a boiler installation certificate which ensures your boiler is clean and working.

If your heating system is working fine, you will only need a power flush every 5 to 6 years. This prevents damage to metallic components and flushes out sludge buildup and blockages.

Fixcrowd engineers are just a call away. Our on-call emergency plumbing services cover residential, commercial, and investment properties. Our services cover installing and fixing bathrooms, sinks, dishwashers, showers, gutter repairs, burst pipes, radiator installation, and more.
