The Ultimate Guide to Quiet Boilers

If you’re thinking about replacing an old noisy boiler with an almost silent boiler, this guide will help you narrow down your quiet boiler options.

Selecting a new boiler for your home is not an easy task since there are so many brands and models to choose from these days. Naturally, you want your replacement boiler to be extremely reliable and energy-efficient and it also makes sense to want a boiler that’s almost silent when operating, particularly if it’s going to be installed in or near the bedroom.

If a quiet boiler is on your priority list, you should seriously think about purchasing one that is Quiet Mark approved.

What is Quiet Mark?

Quiet Mark is an independent approval award programme that encourages companies and manufacturers across the world to prioritise noise reduction within the design of products used in the home, workplace and public spaces. Through assessment and scientific testing, Quiet Mark finds and awards the quietest everyday machines and appliances, enabling consumers to easily identify quieter products, such as boilers, dishwashers and vacuum cleaners.
