As these areas are usually very small, extra heat might be needed. Therefore, it is standard practice to install towel rails combined with the underfloor heating. Always check with the manufacturer of the floor covering if it can be used for underfloor heating. The system must be operated for 21 days with a very low temperature to dry the screed, then the floor covering can be laid. Also note that the screed must be allowed to dry for 6 weeks before the underfloor heating is operated.
Pipe Layout and Design Information. Advice on Insulation and Floor Constructions We recommend a minimum of 50mm of Polyurethane insulation for the underfloor heating system. Moisture Content in Screed and Floorboards The screed must be allowed to dry for a minimum of 4 to 6 weeks before the heating is operated.
Heating in Toilets and Bathrooms As these areas are usually very small, extra heat might be needed.

Please Note: Always check with the manufacturer of the floor covering if it can be used for underfloor heating. Need some advice? Call our experts on Get in touch now. This is so that the pumped pressure and the water temperature is maintained throughout the pipework coil.
Ambiente work out the full requirement of pipework coils and state it clearly in a coil cut table — this will also help the installer to minimise wastage and off-cuts. It is important that the proposed heating control areas are taken into account with the UFH design so that the pipework layout facilitates the required zoning. Ambiente offers many different control options including the Ambiente NeoStat is a slim and stylish smart underfloor heating thermostat that can be controlled from anywhere via the NeoApp, downloadable on any smart device.
We also recommend not running UFH pipework under shower trays, as this can cause the water in the shower trap to smell. Underfloor heating layouts designed using CAD software should always include pipe layouts, heat output calculations, flow rates and pipe allocation. This design should always be completed by a qualified underfloor heating design expert to ensure that all calculations, pipe allocations, pipe spacings, pipe layouts, flow rates, heat losses and heat outputs are correct.
If any of these calculations are incorrect the system may not work as it should. On receipt of your order, Ambiente will produce a full underfloor heating CAD design. The output table gives the system output data, including the room design temperature, the flow temperature, floor covering and the resulting heat output.
We plot the actual positions of the pipework within the floor, to show the installer the exact pattern to work to. We work out the spacing of the pipework for each individual area, and also provide an allocation table to show which coils should be used to cover which loops.
Ambiente utilises specialist CAD software to produce the actual pipework layout and then further specialist software to work out the relating heat output calculations etc.
It is vital that a UFH Design includes both of these components — it is easy enough to draw a pipework layout on CAD, but the calculations that back it up are the most important thing to make sure that the UFH system will do what it needs to!
It is important to understand the difference between Heated area and the Total area — the difference between these two is mentioned about, i. A UFH Design will show these two areas calculated separately — this assists in doing material take-off lists — for example, you only need to supply some products like pipe for the heated area.
It is important that the installer follows the coil cut table that we supply, to make sure that the coils that we supply will adequately cover the installation. Ambiente always allows a small amount of slack on each calculated coil length, to allow for the anomalies that may occur on a construction site.
For example, a loop of pipework may have to be installed around a kitchen island unit that has been moved, or added later — that little bit of slack on a loop will allow the installer some flexibility to modify the installation slightly at his discretion.
Ambiente offers many key underfloor heating resources to installers including UFH installation guides , all the relevant installation manuals and wiring diagrams for the heating control, and even a balancing and commissioning checklist. Following the installation guide carefully ties in with the UFH Design — i. At Ambiente, we understand and appreciate the importance of underfloor heating system design and pay detailed attention to make sure that the systems we design are adequate in terms of being sufficient for the area that you are trying to heat.
The thermostatic mixing head blends part of the cooler water returning from the underfloor heating circuit, with the hot water flowing into the system directly from the boiler, thus ensuring a constant and ideal underfloor heating temperature.
The required water temperature can be adjusted to preference on the thermostatic mixing head. Starting at the manifold, lay the pipe out to the desired start location. Draw a line on the floor mm from the wall you wish to start from.
Start at the mark on the floor and roll out the coil of pipe parallel with the wall, keeping the mm spacing from the wall. Clip the pipe down as you go at maximum spacings of 1m.
To make a turn and run back parallel with the pipe just laid, form a bend in the pipe, clip down and begin rolling back whilst maintaining the required spacing between pipes normally mm.
Make sure to leave enough pipe on the roll to return back to the manifold. Use the recommended pipe cutter supplied to trim the pipe and use the reamer to clean the inside. Before you lay the screed fill the pipes with water and leave it under pressure. You can connect to the manifold and check too. Check for any leaks and drop in pressure. The manifold with the flow gauges the little clear plastic vials is the flow manifold, the other manifold is the return manifold.
The manifold connects to the boiler like a radiator does. If your boiler is a high temperature output like a gas or oil boiler make sure to use some form of thermostatic control to reduce the temperature of the water. Use either a thermostatic blender valve, or if you need a pump too you can make this easier still with a thermostatic and pump blender kit. For systems up to This means the heating would come on and off with the radiators. If preferred you can use a thermostat and a motorised valve.
