Choosing a new boiler for your home and lifestyle

Choosing a new boiler for your home and lifestyle

  • A combi boiler is a simple unit delivers both hot water and heating - making them great for small to medium-sized homes. They heat water directly from the mains whenever you turn your hot tap. Combi boilers don't need a hot water cylinder or storage tank in the loft so you save a lot of space too!

  • System boilers need a cylinder for storing hot water however they don't take any space in your loft with this boiler type some of the main heating and hot water components such as the pump are built into the boiler itself so it is quick and easy to install. System boilers are ideal for homes with 2 or more bathrooms as they can allow you to have multiple showers running at the same time.

  • Regular or traditional boiler need both a hot water cylinder and tanks in the roof. These boilers are also perfect for homes where a lot of hot water is used at the same time. They are particularly suited to low water pressure areas and for installation on to systems which have a lot of old radiators.

What our customers say

I would highly recommend this company. We needed an estimate and boiler replacement fast so that the damaged boiler would not hold up our house sale. We received an estimate within minutes of requesting it. The Business Manager provided excellent, personal, attentive, timely, friendly, courteous and highly professional co-ordination of the arrangements and fast and easy communication. The engineers were equally professional. It was a pleasure dealing with this company.

Mrs Manson Posted November 2021

Seamless experience from obtaining the quote right through to having the boiler fitted. Really pleased with how the work was carried out. Installation guys were so neat and tidy, dust sheets laid throughout, mess and hassle free. Really helpful and informative, could not fault anything and would highly recommend to others.

Mrs Howkins Posted November 2021

The work was carried out to a high standard. Chris, Jordan and Conner were very efficient and worked hard. They tidied up after them and the job which included alot of new pipework was carried out over 2 days. Nina in the office was very helpful and kept me informed at all times. Thank you all for doing such a good job.
