Boiler FAQs

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.

Can you help me find an installer?

You should be able to find an installer near you via our Find an Installer tool.

You can use our find an installer tool to find an installer near you. Please be sure to check any installer credentials before allowing them to quote or install for you.

This service is a directory service only and not the Gas safe register. You should ensure Any installer you get is registered to do the job required.

What are the internal and external sizes of the BoilerBox

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.

Do I need a magnetic filter on my boiler?

A magnetic filter is an option.

However, you will find some boiler manufacturers insist on certain terms an conditions for extended warranties to qualify.

Any heating system with radiators will eventually form magnetite sludge and it is advised when fitting a new boiler to invest in a magnetic filter to capture this sludge, stopping your radiators and pipework from blockages.

It will extend the life of your heating system when used in conjunction with a system inhibitor to stop the formation of rust.

An inhibitor chemical is a minimum requiremment for your radiator warranty to be valid.

What kilowatt rating do I need for an 8 radiator household for a combination boiler?

To calculate the size of boiler, you need to answer a few questions.

The easier method would be to use our Boiler finder tool.

Just follow the on screen prompts and this will filter down to the best choice of boilers for your needs.

I’m an installer. How can I list my business on your website?

We welcome all installers in our "Find an Installer" pages.

We request you keep your listing factual, as we encourage the customer to do their own checks on any installer they invite to do a job.
