Warmup underfloor heating buying guide

Underfloor heating is a great option when it comes to creating a clean, uncluttered and comfortable bathroom or wet room. In this buying guide, written in conjunction with leading underfloor heating suppliers Warmup, we'll show you exactly what you'll need for your installation.

Across the world, underfloor heating is only used in less than 5% of all homes, however, this number is on the increase, thanks in no small part to the rise of the smart home.

So what is underfloor heating? What are the benefits? What do you need when fitting underfloor heating in your bathroom? What type of floor can it be used with? We'll attempt to answer all these questions and more.

What is underfloor heating?

Underfloor heating is a heating system which, instead of using wall mounted radiators, uses wiring or piping which is installed beneath your flooring to warm your room.

What do I need to consider when installing an underfloor heating system in my bathroom?

  • Bathrooms can often be prone to heat loss, more than other rooms in the home. Therefore, you may need to choose a system with a higher output.
  • Ensure that proper waterproofing and drainage is in place before you begin.
  • Make sure you choose the appropriate system that is compatible with your chosen flooring (see below).
  • By using Warmup insulation boards, this could help lower your running costs by up to 50%.

How much can I save with an underfloor heating system?

Unlike traditional heating systems, which simply heat every room within your whole property, Warmup underfloor heating allows you to heat individual rooms to their optimum temperature and duration. For example, you could heat your bathroom for a few hours in the morning, rather than all day.
