Going underground?

Posted on June 18th 2019

This week we take a look at the pros and cons of underfloor heating systems vs traditional radiators…

If you’re currently renovating, building a new build property or even planning to do either in the near future, one of the early and most important considerations will be your heating and hot water. Once you’ve decided what type of fuel and boiler system you will use, your next big decision is going to be traditional radiators or underfloor heating.

Underfloor heating is still considered a relatively new innovation, however underfloor heating has been used in the UK since the eighties. Underfloor heating is often considered luxurious and favoured in higher end new builds and design-led properties. There are several benefits offered by underfloor heating, but it’s not for everyone, you may find that traditional central heating is better suited to your needs. So what are the pros and cons?

Energy efficiency

Underfloor heating is pretty efficient. In fact, because they distribute heat more evenly around the home, these systems are said to be up to 25% more efficient than traditional radiators. Because they distribute heat in this way, the water never needs to heat to as high a temperature, therefore saving energy and money on your bills. So while the initial cost might be more, you would likely save cash in the long run, while also doing your small bit for the planet.


Also, because heat is evenly distributed throughout the home, underfloor heating systems have little or no impact on the property’s humidity and won’t dry the air like central heating can. In addition, radiators can overheat while trying to compensate for cold spots meaning energy can be wasted, particularly if it gets so warm you need to open a window!

Modern underfloor heating systems can also be controlled zonally – so you might have a thermostat for each room. This means greater control over the heat of your house, and also less energy wastage because you’re not heating rooms unnecessarily.

Design freedom

With all the wall space freed up, underfloor heating also offers much greater design freedom than its traditional counterpart, and underfloor heating works well with all types of flooring.


There are two major drawbacks to underfloor systems and both are much more of an issue to retrofit projects. The cost of installation can be expensive, and the installation may be far more complicated than simply putting radiators on a wall. For either option it’s best to get advice from a heating professional.

Can I have both?

The good news is that you can have both. Because underfloor heating systems run on an individual thermostat, you could choose to have this system in the kitchen and/or bathroom if you were having one or both of those rooms redone and stick with your traditional central heating elsewhere. Similarly, if you were renovating a whole property but didn’t want to tear up the floor in every room, you could have a combination of the two systems to suit, and both systems can be connected to your boiler.

Diamond Gas & Heating offers both underfloor heating and traditional heating systems and our expert customer service team will happily advise on what system or what sort of combination might be right for you.
