Water Underfloor Heating Systems: Wet vs. Dry Installation Methods 

Warmup Clypso UFH

Warmup offer a wide range of water underfloor heating solutions suitable for almost any project. Each of our systems feature a specific installation method and in this guide we’ll explain the main differences between ‘wet’ and ‘dry’ installations. You’ll find out: 

  • What a ‘wet’ and ‘dry’ UFH installation method means 
  • The best floor heating systems that utilise screed for new-builds 
  • The best systems that offer a dry install for refurbishment projects 
  • How to buy a water floor heating system

What is the difference between a ‘wet’ and a ‘dry’ installation method? 

When it comes to installing water underfloor heating, these systems can be divided into two key categories; those that utilise a ‘wet’ installation method and those that offer a ‘dry’ installation. Wet installations require the use of a concrete screed into which floor heating pipes are submerged before allowing this to cure and laying down the floor finish. Whereas the systems that offer a dry installation do not require the use of screeding, allowing a quicker and cleaner installation.   

What kind of projects are a screeded water system suitable for?

Water UFH systems that require a ‘wet’ installation involving screed are typically recommended for new-build projects or larger ground-floor home refurbishments because screeding will increase your floor build-up. Specifying a water system in a new-build project means you will be able to take into account both the dimensions and load requirements for the installation during the design stage of your project; ensuring that your construction will be safe whilst its ceiling heights and window and door levels will be suitable for your needs.

Which system should I choose?

The Clypso System is one of Warmup’s most popular water systems and has been developed for use with floating screeded floors. The Clypso’s heating pipes can be attached to its accompanying laminated insulation panels using innovative connection clips, allowing for a smooth installation and bespoke heating layout. This system requires a layer of screed of between 65 – 75 mm, so as we’ve explored, it’s important to make sure your project’s plans factor in this depth and its weight. The Clypso System can be installed with almost any floor finish, in particular where the flooring may be replaced from time to time. 

What kind of project is a ‘dry’ installed system best for?

As screeding will increase the depth of your water UFH installation, the systems that don’t require the use of a concrete screed are perfect for home renovation projects; dry-fitted systems mean you won’t have to worry too much about the impact of the system on the fixed ceiling heights of an existing property. These systems typically utilise UFH panels which feature channels into which the heating pipe can be fitted and many of our dry-install water floor heating systems also come with in-built insulation. The lack of screed also promotes rapid installation times too. To learn more about retrofitting underfloor heating in a home refurbishment, read our informative guide.
