Positioning the underfloor heating manifold

Positioning the underfloor heating (UFH) manifold is an important aspect of your UFH system. It is often thought that it needs to be near the boiler/cylinder/heat pump. It is in fact better to be in the room where the UFH system is to be fitted or very close by if it’s a single room (single zone) system or somewhere central for multi-room (multi-zone) system.

6 reasons why you need Variotherm wall heating in your home

Wall heating systems work very similar to underfloor heating in that they heat a room predominantly by radiation (like the sun) as a result of pumping warm water through looped pipes.

Wall heating systems are often used as an alternative to UFH in renovation projects. Until the recent additions of retrofit and wall heating systems, installing ufh resulted in the floor having to be excavated. Although Retrofit UFH kits have eliminated the need to fully excavate flooring, this does not mean wall heating systems are now redundant. It is not always economically viable to re-lay flooring after installing ufh such as in renovations of older homes.

Floor surface temperatures when fitting underfloor heating

  Max Floor Surface Temp °C Design Room Temp °C Heat Emission (floor output) W/m2 Occupied
Area 29 20 100 Peripheral
Area 35 20 175 Bathroom
Wet Area 33 24 10

4.1    Ceramic Floor Tiles

Ceramics work well with underfloor heating. They have a nil or very low TOG value and offer very little thermal resistance to heat transfer.   
To avoid cracking of the tiles flexible adhesive and grout should be used.  Check that the adhesive and grout is suitable for use with underfloor heating.

Underfloor Heating Troubleshooting

1. If you have a fault once the system is up and running, the first thing to check is the flow rate in the flow meters. Make sure they are set between 1.5L/min and 2L/min for boiler use and 1L/min for heat pump use. If there is no reading (the red indicator is at the top) nothing is flowing around the loop.

2. Then take off your actuator heads, if you then get a flow or your system then works you know it is an electrical problem. If after taking all the actuators off you still have problems then it will be a flow fault
