New Hep2O low build max panels

Wavin has launched a low build underfloor heating (UFH) panel system that can be tiled directly onto – giving installers a quick and easy-to-fit heating alternative to radiators, particularly on renovation projects.

The Hep²O Low Build Max panels have been specially designed to keep overall floor height to an absolute minimum. At just 15mm deep and featuring pre-routed channels for easy pipe placement, the system allows UFH to be installed quickly on all refurbishment projects – from kitchen re-fits to new spaces created by knocking walls through – without the need for existing flooring levels to be lowered.

Low Build Max is equally applicable for new build jobs and extensions. The panels are of a large enough size – 1,200mm x 600mm – to allow installers to cover large areas at speed without being too bulky to handle.

As the panels can be neatly trimmed using a hand saw and secured using adhesive, installation is simple and can be carried out by just one person if necessary.

UFH as easy as ABC with Hep²O
Low Build Max is the latest in Wavin’s innovative UFH product offering, aimed at simplifying the process of specifying and installing systems for every situation.

Comprising panels, piping, manifolds and heating controls, installation is simple and fast with Hep²O. The lightweight hardware is backed by associated software – HepCalc, a free online estimator tool that makes the design and specification process easier than ever before. Installers are guided through the ordering process step by step, with a series of simple questions collecting relevant project information including room size, floor type, fixing method and control requirements.

The HepCalc software quickly provides a detailed specification detailing all components required, including volume and price. Installers then just have to take this to their local merchant and order the parts over the counter. The software also provides users with heating output details ensuring the system meets customer requirements.

Installation process
Step one – Prepare the floor by making it as level as possible and clearing any dirt and dust.

Step two – Choose where to position your manifold. This will then determine the route of the distribution pipes to each circuit. Consider the complete path of the pipe circuits when establishing where to lay the panels – remembering the maximum length of one circuit is 50m.

Step three – Line up the return and channel panels so your pipe can easily flow through the system.

Step four – Cut panels to size where necessary using a hand or power saw. Mix adhesive according to the manufacturer’s guidelines and clean floor one last time before applying the adhesive.

Step five – Apply the adhesive directly to the surface. When handling the panels, do so from the length ends rather than the sides

Step six – Lay all panels by repeating the above steps. Press gently on each panel to ensure it is secure and in the correct position. Avoid standing on the panels until the adhesive is set, usually five-ten minutes but refer the instructions on the adhesive.

Step seven – Attach manifold to required position, ensuring an accessible route for the pipe work.

Step eight – Unwrap the coil of pipe, following the instructions on the wrapping. Attach the pipe end to the manifold for each circuit needed (see installation guide for more details)

Step nine – Lay pipe in your chosen circuit taking care you don’t exceed 50m of pipe, leaving enough pipe to return back to the manifold.

Step ten – Repeat the installation process for all remaining circuits.

Step eleven – Refer to separate installation guides for connecting thermostats and controls.
