Underfloor Heating Systems
The installation descriptions above are summaries only and should not be taken as full installation specifications
With all Underfloor Heating Systems, the pipe loops must be filled and under pressure during any floor laying process. During periods where there is a risk of freezing, special precautions must be taken.
Battened Floor
This system is designed for use with conventional floorboards, when the battens give a secure position for traditional fixings. Can be used in new build or refurbishment where the low build-up height can be useful.
As the system has low thermal mass, it responds well to changes from the temperature controls. This significantly reduces the chance of heating floorboards past the point at which they are at risk of distortion.
Installation
• 70 wide x 50mm deep (or similar) battens are fixed to the floor. They are left short at wall ends to allow the pipes to return.
• Board type insulation is laid in 2 layers between the battens
• The first layer, 25mm thick, is laid between the battens
• Robbens Steel Pipe Channels are nailed to the battens and the pipes are fitted into the channels
• The pipes are taken around the top of the batten, allowing them to return down the other side
• The 2 nd layer of 25mm insulation is laid, between the pipe clips.
• Robbens Aluminium Heat Conducting Sheets plates (0.6mm thick) are laid in rows across the floor, each plate overlapping the other and with a 200mm gap between rows of plates
• A vapour barrier is usually placed over the Conducting Sheets
• The flooring is fixed to the joists, through the Conducting Sheets
• Requires a 60°C flow temperature, set by the Robbens System Controller
• Low thermal mass system and therefore responds well to control changes
• 70 watts/sq.m maximum output
