Underfloor heating is one of the fastest growing products in the heating sector, largely owing to the type of heat it provides and the lower running costs. Michelle Taylor, underfloor product manager at Myson, explains how to install its Tackernail fixing system
Underfloor heating heats from the floor upwards and so provides a natural, comfortable warmth. It’s a highly controllable form of heating, as you can make each room a separate zone, varying the heat output according to the time of day and location.
It also allows for complete freedom of design, with no wall space taken up by radiators, and is widely acknowledged as being one of the most effective methods of heating.
Myson Floortec offers a complete underfloor solution, with both bespoke systems tailormade to individual requirements, and pre-packed, single-room packs available. Its underfloor heating provides a complete end-to-end solution –
from free 48-hour quote and
design service to technical support, advice and training.
The company also offers a range
of quality components that perfectly complement its systems. The full
range of fixing systems is available
for all floor types. The Tackernail (pictured, left) fixing is one of the most popular and easy to install. It is also exclusive to Myson Floortec, so you won’t find it anywhere else.
Before you start, make sure the area where you are installing the underfloor heating is as clean and tidy as possible. You will also need to lay the insulation (not supplied) in accordance with Building Regulations, ensuring there are no gaps
To make installation even easier, use a Tackertool (see right-hand picture, Step 3), which is available to buy or hire directly from Myson Floortec
Assemble the pump pack using the instructions provided, and attach to the manifold. Mount the manifold on the wall at an approximate height of 600mm, as specified in the supplied CAD design.
Attach supplied perimeter edge insulation around each wall, ensuring skirt faces into room. Fix to wall, using tacks or tape to keep in place. Polythene skirt lies on top of the insulation, preventing screed travelling underneath.
Uncoil the PEXcellent pipe, and secure one end to the manifold. Referring to the Floortec CAD design, lay pipe at required centres. Fix using pipe stapler or by hand, using reverse snail or serpentine pattern.
Pressure-test the system by connecting the brass hose to the filling and purging valves. Open the valves and flush water through the manifold one port at a time, starting with the
port furthest from the hose.
With the pipe laid and under pressure, you can now screed the floor. Allow enough time for the screed to dry before
you lay down the chosen floor type.
Myson electronic controls can now be installed. Make sure that your thermostats, wiring centres and actuators are installed by a qualified electrician, following the wiring diagrams found in the installation manual supplied.

As an industry we know that the future is smart. But there remains a perception issue among consumers, who often believe smart controls are costly and disruptive.
