What Is a Heating System Conversion?

A heating system conversion from an outdated gravity system to a pressurised combi system, involves upgrading your heating and hot water setup to a more efficient and space-saving solution. This conversion brings several significant advantages, and we’re here to outline them for you.

 

First and foremost, during the conversion, several components of your existing system will be removed. This includes the cold water storage tank, expansion tank, hot water cylinder, and all other external components associated with the gravity system. By eliminating these elements, you free up valuable space in your property, making it more efficient and organised.

 

With the installation of a pressurised combi system, you’ll enjoy the benefits of mains pressure throughout your home. Unlike the gravity system, there will be no need for noisy shower pumps, as the water pressure will be provided directly from the mains supply. This ensures a consistent and powerful flow of water, enhancing your showering experience and overall convenience.

 

No more programming timers or waiting for hot water. With a pressurised combi system, hot water is generated on-demand, providing instant access to hot water whenever you need it.

I had received an extortionate quote from another company and wanted to compare it to Master Gas London. I spoke with Ed and he was so knowledgable and honest. He took the time to explain the different boiler options and let me know the pros and cons of the different boilers. He was very patient and I am so appreciative of the time he took with regards to the choices I could make. It is such a shame I am located too far away to use this company, as their professional response and advice was outstanding.

Highly recommend. Could not fault Ed and Tamer. They were efficient, on time, went out of their way to ensure we were pleased with the work, and took time to explain the new system. The work was finished to a high standard and all pipework routed beautifully.

I was very anxious about my boiler to be fixed properly until I found Ed from the first telephone call, my anxiety has been eased off immediately because he was so polite, explained potential issues and he tried to book me in as quickly as possible even though he is very busy. He was so professional from beginning to end. At the site he investigated the problems and explained to me the issues and he didn’t leave until everything was sorted out properly. Today I was able to take a comfortable bath for the first time in a long time. Thank you Ed. Highly recommend and will definitely recommend to my friends!

Ed and team came to install a new boiler a few months back and I've been meaning to leave a review ever since because they were so great. Worked all day and didn't leave us until everything was working. They are more than happy to stay in touch if there's any follow ups too which is great.
