Water Underfloor Heating Systems

So what is water underfloor heating?

Wunda is one of the leading designers and suppliers of water-based Underfloor heating in the UK, supplying the most energy efficient heating systems currently available for new and older homes. A Wunda underfloor heating system turns your whole floor into a low temperature radiator.

The large surface area doesn’t require a high temperature to warm the room, therefore using less energy with a fast heat up time and comfortable heat. Wunda’s Rapid Response® underfloor heating systems are the modern solution to any home, and the combination of Rapid Response® with Wunda home heating controls, can save up to 50% on your home heating bills

Wunda’s Rapid Response® system

Wunda’s Rapid Response® heating boards suit almost any floor finish with fast heat up and cool down times, as well as the traditional Screed and joist systems.

Other systems

Wunda offer a range of underfloor heating systems to suit all properties.

Screed

All you need for your screed system using close pipe centers and set-back thermostats for increased control.

Joist

Running warm water pipe through either Aluminium Spreader Plates or aluminium coated EPS Between Joist Panels and relaying your floor boards.

Radiators

Produce hot ceilings and cold floors because heat rises up where it pools until it’s forced down by air circulation…

Underfloor heating

Comfortable heating rises up naturally from the floor, warming everyone & everything from your feet up.

Radiators vs Underfloor Heating comparison

Underfloor heating gives the same heat output as radiators while using much lower temperatures which means running costs are reduced, in the long run underfloor heating is cheaper than radiators as your whole floor becomes your heat source and since Wunda’s Rapid Response® heating system replaces your radiators you can free up space in your home and reduce the amount of drafts that radiators cause.

Running costs

Save money and the planet!

Along with the added benefit of a zoned system that only provides heat to where you want it, Underfloor heating runs at a much lower temperature than radiators. It only needs water at 35-45°C, saving you huge amounts on your utility bills.

Underfloor heating for different buildings

No matter what kind of building or renovation project you are doing; your choice of heating system should be a serious consideration. Especially with today’s energy problems. Wunda’s Water-based floor heating systems are the most efficient, controllable and comfortable heating systems available, getting maximum efficiency out of any heat source, boiler or heatpump.

Underfloor heating for different floor coverings

Underfloor heating works with most flooring types, some work better than others but all work very well! It’s always necessary to check with your flooring supplier for suitability and recommended installation techniques. Find out more about different floor finishes here.

Your UFH Questions

We recommend having regular servicing to maintain an efficient system, when you have the boiler serviced for example to check inhibitor levels are still ok, no air locks in the system causing poor performance. With regular preventative maintenance, you will have no problems of breakdown

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.

Our experts are more than happy to offer FREE advice before, during and after your system has been installed – just call or email us. Rest assured though that all of our components carry long guarantees and are backed up with a £10M Product Liability insurance with AXA.

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. Any competent plumber can easily do this work for you.

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.

Warm water is pumped from the heat source to the manifold. If the floor heating requires warm water, the thermostatic valve will open allowing heated water into the manifold. From the manifold, heated water is pumped around the floor heating pipes, returning to the manifold and then either released back to the boiler/heat source via the boiler return valve for re-heating or blended back into the floor loop via a one-way valve. When all rooms reach desired temperatures, the room thermostats will signal to the actuators and pump to shut down, this in turn stops heated water circulating through the floor.

A great experience working with Wunda. The product itself is great and when I had an issue their customer service team was only to happy to help and went above and beyond. Looking forward to getting plenty of use out of their system. Would highly recommend
