Snug Water Underfloor Heating

Powerful, efficient systems you can use anywhere

Water systems, often called wet systems, are very versatile. From a single kitchen to a whole hotel, if you’re looking for great efficiency, they’re the best choice. They can be tuned to give out exactly the heat each room needs, and no more, creating comfortable warmth and cutting energy bills.

To get the best results from a water underfloor heating system, you’ll need to choose the right type for your particular needs. Here’s our quick guide to your options, for more detail or further queries, please don't hesitate to contact the Snug technical support team on 01772 761333 or email

Screed systems

There’s no doubt about it, screed systems give you the best possible output. They’re also the cheapest option and the most efficient. The drawback is, they need space. Typically, they need around 200mm because they rely on heating a thermal mass. There are three different screed systems to choose from

  • Staples: the cheapest way to lay this kind of system on a budget.
  • Clip rails: easier, faster installation, great for big, open rooms.
  • Castellation mats: the most expensive screed option, but the fastest. They’re also ideal if you’re laying a water system on a solid concrete floor without installation.

Low-profile systems

These are great when you’re retrofitting underfloor heating or working with low ceiling heights. They’re also perfect when you’re fitting a water system upstairs because they only need 18mm of space. Plus, they’re easy to install, even if you’re doing the job on your own. Adding our Snug Support low-profile ends makes installation much faster and easier too.
