At Wunda we know how important it is to get your order to you quickly. For areas in the UK mainland if you place your order before 6.00pm we can provide our standard delivery in the next 2 – 3 working days.
Joist systems are perfect for upper floor properties.
Ideally the manifold should be sited as centrally as possible. The manifold position will be marked on your pipe layout drawing. It can be hidden inside an existing cupboard or we can provide an elegant manifold cabinet.
A manifold allows water to pass through its hollow core, this water then is distributed to the relevant destination (loop/zone). It will generally incorporate a pump and mixing valve to circulate the water around the loops & regulate the water temperature to a point that is suited for the floor finish
We supply pipe layout drawings which detail where every loop of pipe is laid and the length of each loop. You or your installer can’t go wrong!
Water based floor heating is laid using continuous loops of pipe in the floor, meaning the only joins are at the manifold – not under the floor.
Pipe that is pressure sealed at the point of manufacture like Wunda’s emits a hissing escape of air when the seal is cut on site. This allows the installer to safely guarantee the pipe is 100% leak proof before install and will give you peace of mind too.
Screed systems are traditionally used in new build projects. Screed systems require the floor heating pipes to be fixed to the sub floor insulation layer prior to being encased in a layer of concrete or chemical screed. The warm water in the pipes heat up the concrete (screed) which acts as a thermal store and radiates it into the living space. This process can take a few hours to both heat up and cool down and is less controllable than overfloor systems.
A hardwired thermostat is powered by a 240v mains supply, a physical wire (3 core plus earth) Is used to trigger the appropriate output, to a wiring centre if one of many thermostats, or directly to the output if a single zone.
A wireless thermostat communicates to a receiver using radio frequency (RF) (either single channel or multi zone depending on the number of thermostats you have) meaning no need for wiring between the thermostat and manifold. Our RF thermostats cannot take a floor limitation probe so other steps are required to protect temperature sensitive floor finishes.

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 Wundatherm® 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.
One of the best things about floor heating besides the unparalleled comfort, is that a well designed system doesn’t require regular maintenance, it just works!
Have your installer insert an inhibitor and there’s no need to bleed the system, because with auto balancing actuators the system control centre maintains itself, ensuring fast and even heat throughout your floor.
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.
Thanks to retro-fit systems like Wundatherm® 100m2 can be laid in just two days using quick drying Wunda Spray adhesive. It’s no longer a case of digging all your floors up, simply take up your carpet, prepare your sub-floor and lay a retro-fit system.
Retro-fit options like Wundatherm® are laid directly under your floor finish and when covered with the optimum thickness of 200 micron aluminium they provide Rapid Response® warmth reaching desired temperatures in 30 minutes and ensuring an even heat across the entire floor – this makes floor heating just as controllable as radiators.
Old fashioned floor heating laid deep in concrete could take up to 72 hours to heat up or cool down.
No! That’s the old fashioned way. Modern floor heating such as Wundatherm® comes in moulded, easy to shape, high density polystyrene aluminium coated boards made from eco-friendly EPS (as opposed to harmful XPS). The board is bonded to the existing floor before running the pipes in and through to the manifold. The desired floor finish is laid on top – no digging, no mess!
