Now, here’s the real beauty of combi boilers – they’re not just efficient; they’re also space-saving champs. You won’t believe how much space you’ll free up in your home because you won’t need that bulky hot water cylinder.

Changing to a Combi Boiler FAQs

What is a combi boiler, and how does it work?

A combi boiler, short for combination boiler, is a heating appliance that provides both hot water and central heating from a single unit. It works by heating water directly from the mains supply whenever you need it, without the need for a separate hot water tank. When you turn on a tap or a heating radiator, the combi boiler activates, heating the water and delivering it instantly to your taps or radiators.

Are combi boilers energy-efficient?

Yes, combi boilers are generally energy-efficient because they heat water on-demand, avoiding the energy losses associated with keeping a hot water tank constantly heated. This efficiency can lead to lower energy bills and reduced carbon emissions, making them an eco-friendly choice for heating and hot water.

Can I use a combi boiler for larger properties?

Combi boilers are suitable for small to medium-sized homes with a single bathroom. If you have a larger property with multiple bathrooms or high hot water demand, you might want to consider a system or regular boiler with a separate hot water cylinder to ensure an adequate supply of hot water to all areas of your home.

How often should I service my combi boiler?

It’s advisable to have your combi boiler serviced annually by a Gas Safe registered engineer to ensure it operates safely and efficiently. Regular servicing can also help identify and address potential issues before they become costly problems, extending the lifespan of your boiler.

What can I do if my combi boiler loses pressure or has no hot water?

If your combi boiler loses pressure or you’re experiencing no hot water, you can try repressurizing the system using the filling loop (usually provided with the boiler). If the issue persists, it’s best to contact a qualified engineer as there could be a more complex problem with the boiler, such as a faulty component or a water leak. Never attempt to repair a boiler yourself unless you are a certified professional.
