Underfloor Heating is an ideal addition for ground source heat pumps. Together, they combine to provide you with an efficient, low-temperature, cost-effective floor heating system.
Using the benefits of rising heat and lower flow temperatures to bring the heat to the floor surface, Severn Valley Renewables provide a heating system that is not only working towards a better environment but is economical for you too.
Underfloor Heating System Types
In a screed underfloor heating system, Insulation boards are placed on top of a ground bearing slab, block and beam or concrete floor. The underfloor heating pipework is then fixed onto the insulation using the supplied cliprail and clips.
A final layer of concrete/screed will then be poured over the pipework. Alternatively to the standard cliprail and clips, A142 builders mesh can be laid onto the insulation allowing the pipe to be secured in position using the supplied cable ties.
This is typically used where a mechanical fixing is required for a timber floor finish. Timber/battens are fixed at 400mm centers throughout the property. Insulation boards are then placed in between each timber/batten. Pipework is then fixed onto the insulation using the supplied cliprail and clips. A layer of concrete/screed is then poured over the pipework.
This system is typically designed for houses where there are suspended joists at 400mm centres. Aluminium plates are fixed to the top of the joists using staples/nails. Pipework is then laid within the plate which will spread the heat across the floor covering above. Insulation boards must be cut and fixed directly beneath the plate to prevent any downward heat loss. In some instances, the Joists cannot be notched or the joists are not at 400mm centres, if this is the case a cross battened plate system can be installed. A 20mm timber batten is fixed at 90 degrees to the existing joists, the plates are then fixed to the battens.
