You have probably heard of underfloor heating, and are curious about this heating system that lots of other homeowners have been raving about. And homeowners indeed have a reason to be enthusiastic: underfloor heating is an efficient alternative to conventional heating systems as it supplies better warmth in the entire home, making it more cosy and comfortable for everyone in your abode.

But as with other major decisions, it is always in your best interest to know more about what this type of heating system entails.

How warm water or wet underfloor heating works

There are actually two types of underfloor heating systems: one based on electricity, and another which makes use of water. Today, our focus will be on the water underfloor heating system and how it functions.

A water underfloor heating system makes use of a series of different pipes which are all connected to your home’s boiler. These pipes are installed under the floor, and the warm water runs through the pipes, therefore making the floor warmer. This warm air then circulates around the room. The concept behind a wet underfloor heating system is simple, but it has worked wonders for different spaces. Why? Because the heat which is emitted from the floor is distributed more evenly than, say, a radiator.

A radiator is only designed to heat up a specific area, resulting in some cold spots. But a wet underfloor heating system is better, not only because it results in a more even distribution, but also because this same distribution can make use of water at a lower temperature, therefore making it more efficient and cost-effective as well. The numbers don’t lie: a water-based underfloor heating system is 3% more efficient than radiators, as shown by SAP (Standard Assessment Procedure) 2009.

More useful facts about wet underfloor heating

Wet underfloor heating can be installed in homes which are still being built, or they can be installed retroactively. They are flexible as well – you can have one installed whether you have a concrete or stone floor, tile flooring, wooden floors, or even carpeted floors. To make underfloor heating more effective on carpeted floors, it is generally recommended that the carpet have a tog which is less than or equal to 1.5. Carpets that are too dense may hamper the warm air from being distributed properly. Those with allergies can also benefit from underfloor heating, as dust is not typically distributed, unlike with radiators.

It has also been shown that water underfloor heating is more energy efficient than your conventional radiator heating system. In fact, the EST, or Energy Saving Trust, has stated that a wet underfloor heating system costs less in the short- and long-term to run. The more advanced underfloor heating systems can save you from as much as 15 to 30% on heating costs.

Also, if you are more concerned with having an energy efficient home and making use of renewable energy, wet underfloor heating systems from experts like are ideal, as they can be made compatible with renewable energy sources.

At the end of the day, it is a major decision to have wet underfloor heating installed for your home. But the benefits are immense, and those who are seeking a more comfortable environment would do well to make wet underfloor heating their ultimate choice.
