Boiler Replacement and Installation
- Uxbridge Boilers

Uxbridge Boilers@ offers a boiler replacement and installation service in Uxbridge and West London.

We repair boilers, so we know what might cause a boiler to stop working. Thus on our boiler installs we tend to avoid any weakness in order to prolong the life of the boiler.  

As we said in the repairs section, boiler replacement is easier than boiler repairs. Despite this, we also install boilers if it is necessary. We have a successful tracking record of boiler installation. In 2022, we installed over 40 boilers, ie, an average of one install per week, more than half of the boilers we installed were from Vaillant.

Being competent and honest in boiler repair work has led us to being asked to carry out more and more boiler installs / replacements.

We only install decent boilers!

Since 2015 we have been granted as a Vaillant masterTEC elite installer - The very top grade of Vaillant accredited installers. Vaillant gives the boilers we install one extra year's warranty. It is assessed on the loyalty, number of boilers installed, and rate of warranty call outs.

So, we must have done something right with our boiler installations!

Gas Safe competency

To install a boiler, an installer has to be on the Gas Safe Register. Unfortunately, in our repair practice we have seen many cases where boiler installations are not up to standards, leading to a boiler's breakdown and even to unsafe situations. We are Gas Safe Registered, not only for domestic boilers, but also for commercial boilers bigger than 70kW. We are very competent at boiler installations.

Electrical competency

We are also NICEIC registered electricians, Approved Contractor, from domestic up to commercial and industrial. Boiler installations also involve electrical connections and controls, eg, boiler main's spurs, programmers, room thermostats, external pumps and control valves etc. We are in a unique position to fulfill Part P requirements - the domestic electrical safety regulation in dwellings. We are probably the only firm in St Albans to have both gas and electricial professional qualifications.

Beyond economic repair

Herts Boilers specialise in boiler repairs, but sometimes we consider a boiler to be beyond economic repair if the cost of the repair is unrealistically high compared to the life expectancy of the boiler. As a rule of thumb, £150 should give the boiler at least another year of life.

High efficiency boilers

From 2005, all new boilers installed in the UK have to be the condensing type, ie, high efficiency at around 90%, also called A rated. This compare to cast iron type boilers which are only around 55% efficient. A high efficiency boiler will reduce your gas consumption in the long run.

Correct sized boilers

When selecting a new boiler, care has to be taken to ensure it correctly sized - not under and not over. We calculate all the radiator heat outputs along with the hot water requirements to choose a correctly sized boiler fit for purpose. A rule of thumb is 100W for per square meter (or 40W per cubic meter). Thus a 100 square meter house generally requires 10kW the heating side.

Should a new boiler always be a combi?

The combi boiler is a great invention but it is not always right to go for a combi. I our site survey we will give you unbiased advice about which new boiler and heating and hot water system is best for your house and your needs.

We also install system boilers for Megaflow systems, and heat only boilers for vented systems.

Boiler warranty

If a boiler is installed by a Gas Safe Registered engineer up to the manufacturer standards, it will normally be under manufacturer's warranty for a few years. Herts Boilers is an approved installer for the following boiler manufacturers (at the time of writing in Oct 2016):

• Vaillant - 7 years and 10 years
• Glow worm - 5 years and 7 years
• Viessmann - 5 years and 7 years
• Baxi / Potterton / Main - from 2 years to 10 years
• Ideal - from 2 years to 10 years

Once we register an installation with the manufacturer, they will give the client up to 10 year's labour and part's warranty.
