How Much does Underfloor Heating Cost to Install

Many people have the perception that underfloor heating is incredibly difficult to install. Involving huge pipes with lots of digging, often leading to them thinking it will be a costly and stressful process. However, with a Wunda Rapid Response® system, this could not be further from the truth.

There’s no digging up floors and installation is easy and relatively hassle free. 75m2 could be laid over a weekend by competent DIYers ready for your professionals to hook up to your heat source.

Underfloor Heating Energy Efficiency

Underfloor heating uses low (35-45 degrees) water temperatures, making it a very eco-friendly system. It is the perfect partner for heat pumps as their optimum efficiency is producing water under 50 degrees.  

Underfloor heating systems will cost users around 25% less than radiators to run on average and 60% less than electric floor heating systems. When installing a Wunda Rapid Response® system which uses smart controls and zoning the savings can be up to 50%.

Water based underfloor heating does require some maintenance. In comparison to radiators water underfloor heating needs very little maintenance and the maintenance it does need is easier to carry out, as the system is maintained from one central point – the manifold.

The maintenance follows a similar to process to central heating with radiators. Ensure there’s no air in the system by releasing at the manifold and turn on after summer before the depths of winter to check all is running smoothly.

The Rapid Response® heating system is a water-based floor heating system that uses low-temperature warm water to heat rooms evenly and quickly. Input temperatures can be as low as 45°C, using half the energy required to heat a radiator at 70-90°C.

This combined with the on demand nature of The Rapid Response® heating system, allows users to only heat the rooms they’re using, and not have to leave the heating on all the time like old traditional screed systems which took days to heat and cool.


The responsive use and lower energy requirements to run the Rapid Response® heating system make it a low carbon solution that’s compatible with current heating technology like gas/oil boilers; as well as working efficiently with alternative fuels of the future like hydrogen boilers and air & ground source heat pumps.

Not at all! Wunda’s floor heating systems have been developed with the confident DIYer in mind, being able to lay the pipe and panels, leaving final commissioning to the professionals. If you’re extending or renovating, even simpler would be to make use of the builders already on-site and get them to install it for you.

Floor heating and radiators happily work in conjunction with one another, to achieve this you will need to ‘T’ off from your boiler primaries, so one set of flow and return will go towards your radiators and the other to your floor heating system. Your heat source (boiler / heat pump) will still be producing hot water for your radiators, the same temperature water will be blended at the UFH manifold by a mixing valve. So while the heat source is still producing ‘hot water’ the UFH system ensures that you need less of it – saving you energy and money.

Any competent plumber can easily do the work for you to commission your heat source (boiler / heat pump) to both radiators (commonly upstairs) and underfloor heating (commonly on the ground floor).

Electric has much higher running costs in comparison to water based systems making it suitable for smaller areas such as en suites but not for larger living areas and whole homes. For open plan kitchen and family areas, water based systems are more economic costing up to 65% less to run than electric.

Most floor finishes can be used with floor heating, Wunda developed Rapid Response®, high density boards to support heavier floor finishes such as marble and stone tiles. These boards are independently approved by leading tile adhesive manufacturers to be laid directly on top without the need for an intermediary layer that other, less dense, boards may require, this helps to reduce system cost, build up height and lower install time.

If you’re opting for a wood floor be sure to install a floor probe to protect the integrity of the wood from fluctuating temperatures and do check with your flooring supplier as some products such as Beech wood may not be compatible.

No, most users of floor heating install on the ground floor and combine the system with radiators upstairs – but you can install throughout the whole house if you wish.

Absolutely, water based floor heating runs at lower temperatures, normally 35°C – 55°C, which is about half of what radiators run at. Water based floor heating is future proof and can be run from any heat source including heat pumps.
