Boilers that are over ten years old waste a lot of valuable energy, in terms of cost and environmental impact, in fact many older boilers convert as little as 60% of the fuel they use into heat and they can breakdown more frequently. We specialise in Combi Boiler replacement, new installation and servicing of modern highly efficient Condensation Boilers.

Different boiler types

Combination (combi) boilers

‘Combi’ is short for combination, because the boiler does two things in combination. It heats water and provides central heating to your home.

Combi boilers heat water as you draw it from the tap. They don’t need a water storage tank because the boiler’s connected directly to the water mains, heating water as it’s needed.

Homes which suit combi boilers

Combi boilers are cost effective and energy efficient, with a compact size that’s ideal for smaller properties where space is limited. Because there’s no need for a water storage tank or a hot water cylinder, a combi boiler can free up space for conversion, storage and living.

System boilers

System boilers – also known as sealed system boilers – need a water cylinder to store hot water, which usually sits in an airing cupboard.

In a system boiler, the heating and water systems are built into the boiler itself – there is no need for a water tank like you would need for a regular boiler system.

Homes which suit system boilers

System boilers are ideal for homes with more than one bathroom, and can give a constant supply of hot water to any number of taps at the same time.

Regular boilers (open vent)

Regular boilers – sometimes known as open vent, heat only or gravity-fed boilers, provide central heating and hot water through a hot water storage cylinder, often found in an airing cupboard, and cold water tank usually found in the loft.

Homes which suit open vent boilers

If your home has multiple bathrooms, open vent boilers are perfect as they can provide a lot of hot water at the same time. Open vent boilers work well if you are replacing an old open vent heating system, and are ideal if water pressure is low in your area.

“Really impressed with Antonio and his team. He turned up when he said he would and clearly explained what the problem was with my central heating. Great workmanship and very reasonably priced. Would highly recommend and will definitely use him again.”

Hove, December 2018

Complete refurbishment of bathroom and downstairs toilet room.

“We are very happy to recommend Antonio. I felt comfortable having him around and could trust him completely. He was so careful to clean up and keep tidy. He oversaw the project, doing the plumbing and using his own trusted contacts for all elements of the refurbishment including tiling, electrics and plastering.”

Brighton, July 2018

Bathroom refurbishment.

“Antonio and his team have done a fantastic job, and I can’t recommend him highly enough! He was extremely professional, but very friendly and personable, which made the whole process surprisingly stress-free. Living in a 200 year old flat meant this wasn’t a straightforward job, but Antonio not only managed to find solutions he completed the job to a much higher standard than I thought possible. The whole team turned up promptly throughout, and Antonio made sure I was kept up-to-date with everything. I wish I could use Antonio for all the work in my flat!”

Brighton, April 2018

New bathroom vanity unit.

“Antonio arrived on time and finished the work within his original estimated time frame. Extremely efficient with attention to detail yet maintaining a sunny upbeat manner throughout. All completed and left tidy. He also fixed a leaky expansion tank in the loft as an emergency call out during the previous icy spell at a very reasonable fee. All in all this guy is a truly unusual find - a reliable trustworthy and honest tradesman and true professional with a cheery upbeat 'can do' attitude.”
