Customer Questions
How can I work out what boiler I need?

Finding out what boiler you need is a serious question.

To answer this question it deserves a little more attention than an FAQ section can provide. That's why we have created our Find a Boiler tool.

Just follow the easy to use steps and we will show you the options that best suit your needs.

What are the internal and external sizes of the BoilerBox

Inner - 76.8cm L x 57cm W x 41.5cm H - Outer - 80cm L x 60cm W x 44.5cm H

Are your products guaranteed?

Yes all our products come with a guarantee.

Guarantees or warranties vary, by product and manufacturer.

All our products are guaranteed for a minimum of 1 year (radiators 10 years, copper tube 25 years) but many offer longer warranties from the manufacturer, which you may need to register for.

On each product, under the specification tab, you will find more information on the guarantee or Warranty.

Follow links through to various manufacturers sites, as each manufacturer will have its own terms and conditions for qualifying for longer warranties.

You do not want to miss out by getting the wrong installer for some boilers etc.

As Boilers and radiators are installed by third parties, they do have to install in compliance with regulations and manufacturer standards to get the full benefit of the warranty.

As long as these ar fulfilled, you will get the maximum life and support from your new purchase.
