Boiler FAQs: Your Kitchen Boiler Questions Answered

All we really want is to stay warm... but when it comes to boilers in the kitchen, heating never seems quite so clear cut. To help out, we’ve created a comprehensive guide to the most common questions we get asked about the practicalities and workings of central heating systems.  

Read on for our definitive guide to boiler replacement, location and safety requirements in your kitchen. We’ve got all the answers to your queries about the best place to put your boiler, how well it needs to be ventilated and how to cover up boiler pipes. 

Can You Fit a Boiler in a Kitchen Cupboard?

The short answer is yes, but there are other factors to consider before deciding where to place your boiler. Don’t forget to consider fire safety standards, leave plenty of space for servicing and maintenance, and check the manufacturer’s instructions around flueing and ventilation (read on below for more information). 

A quick search online can help you find some fun and stylish inspiration for the best place for your boiler depending on budget, from custom-built cupboards to purpose-built spaces. At Ideal, many of our boilers boast a compact cupboard fit — from new Combi Boiler installations to Heat Only models.  

Does a Boiler Cupboard Need Ventilation?

A source of ventilation is a necessity for boiler cupboards, providing a steady stream of cooling air and ensuring your boiler works efficiently to combust fuel and produce heat. The exact amount of ventilation needed will depend on the type of boiler — pay special attention to the manufacturer’s guidance for your particular model. 

Don’t forget to ensure there’s a minimum of 50mm space between your boiler and the top, bottom and edges of the inside of the cupboard, allowing easy access to your boiler for day-to-day use and annual servicing.

How Long Does It Take to Fit a Boiler?

We have answered the question of how long it takes to fit a boiler in more detail elsewhere on the Ideal website, but here’s a summary of what to expect. There are several factors that will have an impact, including whether you already have a boiler installed and the type of model, whether it needs relocating, and what type of fuel it uses. 

As an estimate however, installing a new boiler will generally take between six hours and four days. If you need help finding the right boiler for you, why not take advantage of our free tool that matches the right model to your needs

Does My Boiler Need to be Fitted on an External Wall?

Your boiler should ideally be located on or next to an external wall, which will allow any waste gases to escape safely and easily outside through the flue duct. Because of government regulations, the flue needs to be placed around 30 to 60cms away from any openings where air can enter your home from outside, such as windows or doors. 

Other factors to consider when deciding on the best location for your boiler is how close you want it to be to household appliances that use hot water — the nearer they are to your boiler, the faster it will be able to reach them. 

How Can I Cover Boiler Pipes in My Kitchen?

If you’re tired of the sight of boiler pipes in your home, you’ve probably considered covering them up to make your space tidier. If that’s your plan, it’s vital to ensure your boiler and pipework have the ventilation they need to make sure all of their components can run safely. Plus, whatever materials you use to cover the pipes should meet requirements around fire safety.

Don’t forget that your boiler will also still need to be accessible enough to be reached when it’s time for its annual service.
