Underfloor heating UFH systems are not difficult to design or to install, but it is important that the guidelines and instructions are carefully followed to ensure that the system performs correctly once installed and has a long service life. This guide explains the fundamental principles and design of Uponor UFH and also gives installation guidelines for the components and systems. Download also: Heating Boilers Design Books. Starter Guide. Electric v Water Underfloor Heating Both electric dry and water wet underfloor systems can be really great — so give yourself the time to look at both.
Market leading brands. New to underfloor heating and not sure where to begin? We've got you covered Get a Quote Loop the pipe across the whole floor area.
Use multiple loops for large spaces. The pipes must always be pressure tested before the screed is laid. Equally important is to ensure the pipes are full of water while the screed is being laid so that if there is any damage it will be immediately obvious and can fixed before the screed laying is finished.
Sign in. 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.
