New boilers with a 7 year warranty!
We're Vaillant Approved which means we can give our clients a massive 7 year manufacturer warranty when they purchase a new Vaillant boiler and have it installed through us. Plus; we offer free quotations and if someone does come in cheaper for a like-for-like spec, we'll always discuss ways that we can reduce our quotation.
Repairs & Servicing
We can undertake all aspects of central heating maintenance from basic servicing, to 5 yearly manufacturer strip-down services and overhauls to radiator valve changes and controls. We've got every aspect of gas central heating covered.
Combi's, as they are known in the trade, are now the most used form of central heating boilers. Most Combi's run on mains pressure water, therefore do not require tanks to be placed in the loft. They also elimate the need for a not water cylinder as they instantly heat the water when it is needed. Another benefit with the combi is that, due to it running from the mains water supply, you can create an effective power shower with the need for a pump.
Combi boilers require the least amount of plumbing thus offer a cost saving when installing. Just like its name these boilers combine heating a hot water all in one. No tanks and instantaneous hot water whenever you open a hot tap. The temperature at the tap is dependent on the temperature of the mains supply and the flow rate.
All boilers should be inspected and services once a year during the summer to ensure that they will be reliable for the coming winter and beyond. It is far better that any heating problems should arise during the summer than in the middle of winter. We are happy to work on all Gas Combi Boilers. Our vans carry a multitude of spare parts for many boilers and most repairs are done with just one visit, saving you time and money.
Flues in Voids
In January 2013, the law changed, if your boiler has a fanned type flue which travels in a "Void" or a space which has no inspection points, then it will be classified as "At Risk". You will need to get a local builder to provide access hatches to allow the flue to be inspected throughout it's length. A boiler that is classified as "At Risk" should not be used until a Gas Safe Registered engineer has deemed the remedial works as satisfactory and removed the At Risk notice.
