Glowarm is a friendly family run business which has been established for over 30 years and has grown to be one of London's and the Home Counties leading central heating companies. We take pride in treating our clients on an individual basis, taking great care to ensure that we understand your exact needs, and that our work meets those requirements in every way. Make sure you have the right central heating system installed in your home. Glowarm's heating engineers based in London offer expert advice and options to ensure your home is kept nice and warm in the colder months.

Not everyone has the space for a hot water tank. A combi boiler eliminates the need for storage tanks. With this type of condensing boiler, hot water is heated instantaneously when you turn on a tap, so you don't have to wait for the hot water cylinder to heat up or keep it on standby, and you'll never run out of hot water!

Perhaps you're starting a family or extending your home? Maybe your old boiler and controls are simply no longer up to the job? Undertaking a new boiler installation is not as daunting as you may think, give the team at Glowarm a call for advice and a free, no-obligation quotation to ensure you make the right choice.

If so, you will know the costs involved in replacing some of the many components that often breakdown on boilers and central heating systems. To ensure that your central heating system is working safely and efficiently, the plan also includes a full boiler & system service, this will be carried out either on inception of the plan, or within 28 days of the plan being taken out. Alternatively, you can book the annual boiler service and our engineer will complete the documentation when he calls.

If you feel that your radiators could be a bit hotter, or the system is noisy and generally nor performing as well as you think it should, then there is a possibility that there may be a sludge build up in your system which requires cleaning. Sludge in heating systems can drastically affect the performance and efficiency of your boiler, and is almost certainly costing you money. Power flushing is the easy solution to this problem. By connecting a power flush machine to your central heating system and circulating a special cleansing chemical ensures that your system is clean and working to its full efficiency, saving money on running costs and reducing your fuel bills.

All gas appliances should be serviced at least once a year. This is to ensure the safe and smooth running of your gas boiler or water heater for the next twelve months. It is vital that all the safety controls are tested to ensure they are functioning correctly, and the flue examined to ensure you are not at risk from potential dangerous gas appliances. The internal components, such as burners and pilots should be cleaned to ensure they are burning cleanly and correctly, along with checking gas pressures and water flow rates.

We don't have to tell you how dangerous an un-serviced gas appliance can be. The awful stories you see in the press regarding carbon monoxide poisoning fatalities are usually always down to a faulty or un-serviced gas appliance. It is extremely important that all gas appliances are serviced at least once a year, even if your boiler appears to be working fine. You would not consider driving a car without an MOT, the same ethos should apply to gas boilers, as both are equally as lethal if not checked once a year and deemed safe to use by a professional engineer.

Glowarm can offer a boiler repair service that is second to none. Our Gas Safe registered boiler engineers pride themselves on their ability to repair practically any gas boiler, old or new, in homes today, with the minimum of fuss, at very competitive prices.

All new boilers today, whether they be conventional or combination, will be a condensing boiler. Here at Glowarm we install, service and repair both types of boilers for our customers throughout Mitcham, Carshalton, Sutton, the rest of London and Surrey. Condensing boilers use modern technology to re-use the heat that is currently wasted through your flue, ensuring that all the heat from the fuel goes towards heating your radiators and hot water. It therefore uses less heat from the burner, and as a result is much more economical to run and friendlier to the environment.

Having the right central heating system installed in your home is important for a number of reasons - the amount of people who live in your home and how often certain rooms are used are just some things that need taking into consideration. Glowarm works with two types of condensing boilers - conventional boilers and combination/combi boilers. Our fully qualified and Gas Safe registered heating engineers can inspect the heating and plumbing at your property in order to gauge which central heating system would best work for you.

We had Glowarm build us a new central heating system following a number of leaks with our original system. Dan, Josh and Harry were all extremely professional and considerate in meeting our goal of minimising damage to our property. Dan was extremely conscious of this when conducting the work, and the whole team's work ethic was commendable - going beyond the call of duty on more than one occasion to meet our requirements, even when it made the job harder for them. For this reason, we would have no hesitation in recommending them or hiring them in the future.

Excellent service throughout. Although not the cheapest quote I never felt under pressure from the initial technician who arrived to sign and go ahead with the works. All options explained and never felt that I was being over sold products that were not necessary. Highly efficient engineer who installed new boiler. Works carried out to the highest satisfaction and would definitely recommend.

Thank you for a superb service from start to finish for our combination system installation. British Gas told us that we could not have a combi boiler, as our water pressure was not strong enough (which turned out to be utter nonsense). Of course we got a second opinion from you, and then a third one to referee! I also canvassed our neighbours, who already have a combi boiler. We accepted your quote, rather than the local one, as you had an altogether more professional approach and were happy to install a radiator in our loft conversion too. Gav, the installer, could not have been more helpful and accommodating - even offering to start at 7.30 am so that I could take the children to school and get on with my chores. He even left the place cleaner than when he started! Peter, the electrician, was also very good, and produced a new room thermostat out of thin air for me! The price that we paid was exactly as quoted, and I would happily recommend your company to anyone.
