What is the distance between underfloor heating pipes?
The most common spacing between each pipe run is 200mm. However, this will vary in some instances both wider and narrower spacing, based on the heat loss of the area. Heat loss will be adversely affected by large areas of glazing, or poor insulation values.
Can you control underfloor heating in different rooms?
Yes. This is achieved by having a separate thermostatic zone within each room. This allows total control over your heating and temperatures within the individual rooms.
What is the maximum length of pipe for underfloor heating?
The maximum loop length of 110 m must be used in all installations. It is not advisable to make the loops longer than 110 m. The reason for this is due to the head pressure from the pump, the pump used is only capable of pressurising water through 110m of pipe.
How do I build an underfloor heating system?
The design of an underfloor heating system in a new build is a straightforward process consisting of 6 main steps:
- Calculate heat losses and amount of heat required for each room or zone.
- Determine water flow temperature and pipe spacing.
- Determine manifold location.
- Calculate number of circuits required.
- Plan pipe layout.
Can I lay underfloor heating on concrete?
Underfloor heating can be fitted in both concrete and timber suspended floors, but for other floor constructions (for example we also offer a ‘floating floor’ solution) please contact us.
Does underfloor heating require building regulations?
Part L of the building regulations relates to the conservation of fuel and power and covers underfloor heating. Where underfloor heating is installed, Building regulations now requires that there is a significant level of insulation present beneath the system, to limit downward heat loss.
Should underfloor heating go under kitchen units?
It’s recommended that you lay underfloor heating across the total floor area as the kitchen layout could change in the future. Underfloor heating is not normally placed under sanitary units as they are commonly fixed to the floor and could potential cause damage to pipes.
Should underfloor heating be left on all the time?
It is advised that in the depths of winter, an underfloor heating system should be kept on at all times. Although it should be at different temperatures depending on usage and activity in the house. This is because underfloor heating can take two to three hours to warm up, so it is best to not completely turn it off.
How many Litres of water is in underfloor heating?
Water Capacity Calculation To calculate the water content in our underfloor heating system use 0.12l of water per m pipe. So, for example, 500 m of 16 x 2 mm underfloor heating pipework will have 0.12 x 500 = 60 l of water in the underfloor heating pipework.
What is the best type of underfloor heating?
Screeded wet underfloor heating systems are the most popular and effective type of underfloor heating. Pipes are clipped or stapled onto an insulation layer, then the screed is laid on top. The warm pipes effectively heat up the whole slab, giving even and consistent heat output.
What should be included in an underfloor heating design?
The resistance rating (normally measured in ‘TOG’) is taken into account on the UFH design, to make sure that the heat output will still be adequate, taking this resistance into account. Underfloor heating layouts designed using CAD software should always include pipe layouts, heat output calculations, flow rates and pipe allocation.
What should the pipe length be for an underfloor heating system?
The diagram below shows an example of a pipe layout for a ground floor including suggested loop-lengths and manifold positioning. Underfloor heating pipe should be laid at 200mm centres dependent upon design. The maximum heat output for underfloor heating systems is 100 W/m 2 for concrete floors and 70 W/m 2 for timber suspended floors.
Why do you need a CAD drawing for underfloor heating?
No two rooms are the same, so having a CAD drawing allows you to maximise the space efficiently, create a quotation and install with minimal fuss. Drawings can help show the most suitable length of piping – to minimise wastage, optimised spacing between pipes, and the most suitable location to house manifold/ pump.
