Following on from my first post about what is included in the Polypipe Underfloor Heating House Packs, it is worth noting that although the packs do include everything you need to get your project started there are some additional items that are not included.
The House packs are sold by the floor area and everyone’s requirements will be different.
We have no way of knowing if your building is completely open plan or has many separate rooms, so the number of items like thermostats and actuators that you need would differ greatly depending on how many rooms you will want to control individually.
Below is a quick rundown of items that would need to be purchased separately.
1. Room Thermostats
Polypipe underfloor heating controls mean that you can control both time and temperature via the use of a programmable room thermostat. Each thermostat is wired back to a master wiring centre and can control 1 zone and up to four actuators.
(Note: Rooms over 40m2 should be allocated as 2 zones and have 2 room thermostats.
The PBPRP thermostat allows 24 hour or 7 day timer operation and temperature control with several useful features. There is also a wireless thermostat, code PBPRPRF.
2. Wiring Centre / Slave unit
The Master Wiring Centre and Slave Units operate the relevant manifold actuators, the underfloor heating pump and the two-port zone valve. The number of control zones you require will depend on the number of rooms you wish to control individually.
If you just want to have one single zone then the Single Zone Master, PB1ZM can have the underfloor heating pump, two port zone valve, boiler switched live connection and the room thermostat wired into it directly.
If you want multiple room control, simply add the appropriate ‘slave’ unit. These slave units simply plug into the Master to provide additional connections for the required number of zones.
Also available are Room Temperature Control Packs which include the Master Unit, and the relevant number of thermostats and corresponding Slave Units in one pack. (available as either single, 4 Zone, 6 Zone or 8 Zone packs.)
Remember, the 4, 6 and 8 zone packs describe the number of areas you wish to control, not necessarily the number of circuits you are supplying from the manifold.
3. Valve Actuators
An actuator is required on each circuit that requires control. Each circuits covers 15m2 for Solid (200mm centres), Suspended and Floating Floor, and approximately 10m2 for Solid (100mm centres) Overlay and Overlay Lite Floors.
Up to four actuators can be controlled by each room thermostat. (Pictured is the 2 wire actuator PB00401.)
4. Wet Room Sensor
If you plan to extend the underfloor heating into a bathroom or wet room then you will need the PB23020 Wet Room Sensor which can be sited in the actual bathroom/wet room either on the wall or floor.
The sensor is supplied with a 3 metre cable to connect to a room thermostat but this can be extended with a cable of a similar rating (not supplied) up to 10 metres.
5. Pipe Cutters
Accessories such as glue and tape are included in the relevant packs when needed*, however Pipe Cutters are not included in any of the House Packs.
The professionals may have a pair of trusty pipe cutters but if this is a DIY project then approved polypipe pipe cutters such as PB781 (pictured) are a must-buy for you. It is important that you never a hacksaw when cutting polyplumb underfloor heating pipe.
*(The Overlay House packs include the glue, and the Overlay Lite Packs contain the aluminium tape (ALTP))
