Underfloor Heating
The ROTEX Underfloor heating system provides the perfect partner for the Daikin Altherma range of heat pumps. This system increases the efficiency (COP) of the heat pump and allows optimal individual room design, with easy and variable temperature control.
Features and Benefits
Works extremely well with low temp heat pumps to maxmise COP
Provides a room heat profile close to the ideal heat profile - warm feet
Avoids need for large and unsightly radiators
Adds marketing value to the property
Very popular with developers/end users
Virtually maintenance free
Great for tiled and modern floor finishes
Product Overview
Underfloor systems are made up of 4 main components:
1. Pipes
Monopex PEX-b:
Diameters 14-20mm. Aluminium version available too.
Very flexible and ideal for UFH applications.
System 70 (Duo double walled pipes)
Two layers: (1) inner PEX-B pipe and (2) outer PE pipe which is separated by an air gap
Ideal for mixed radiator / UFH systems and avoids need for complex mixers.
2. System pipe fixing plates
Rotex offers five different types of extruded polystyrene sheets
Each has individual thermal, point loading and acoustic performance
Pipe spacing and runs can be accommodated precisely and easily for the installer
3. Manifolds: the heart of the UFH system
Manufactured from high density polypropylene.
Manifolds are ordered for 2 – 14 UFH loops
Complete with pressure gauge, temperature gauges, isolating valves, air vents and flow meters.
4. Controls
Full range of room thermostats and individual room controls.
