Most underfloor heating systems above 25 sqm will need an underfloor heating manifold. The underfloor heating manifolds should be located centrally in the building. Normally one manifold can do up to 180 – 200 sqm floor area depending on the floor layout. A normal four bedroom property will have one manifold for each floor. Our underfloor […]
Water underfloor heating outputs are quoted in W/sqm. The maximum underfloor heating output for underfloor heating in a concrete floor is 100 W/sqm, the maximum heat output for a timber suspended floor is 70 W/sqm. Watts is a measure of heat energy required. The higher the W/sqm, the more energy is used by the heat […]
We offer a range of accessories for our water underfloor heating systems. 12v Power Supply unit can be used to power our low voltage underfloor heating room thermostats. Our sensor housing, is ideal to be used in en-suites and bathrooms to house the remote sensor for the underfloor heating room thermostats. Power relay card is […]
Our underfloor heating central wiring switch boxes have been designed to simplify the wiring process for our water underfloor heating systems. Using the Heatmiser UH1, UH2 or UH3 in your underfloor heating systems applications, means that the actuator, boiler and pump connections are wired from a single point. Our underfloor heating 12 V network thermostat […]
The UH1 underfloor heating wiring centre also takes care of the hot water control. Controlling the hot water from the UH1 underfloor heating Heatmiser wiring centre makes sense, not only because it simplifies the wiring, but also because it enables you to control your hot water centrally from the Heatmiser underfloor heating TouchPad and remotely […]
Below we have compiled some useful guidelines to help answer some common questions about the installation of water underfloor heating; Flow Rate To calculate the flow rate for each underfloor heating loop, take the loop length and divide by 40. For example, 100 m loop length/40 = 2.5 l/min flow for the underfloor heating loop. […]
Normally the underfloor heating flow rates per underfloor heating water loop is between 1 – 4 l/min. The flow rate for the water underfloor heating system can be regulated on the underfloor heating return manifold. Each loop can be adjusted to suitable settings. ie longer loops would normally be fully open and the shorter loops […]
Most floor finishes will work well with underfloor heating. Always check what the maximum surface temperature the floor finish will operate at with the manufacturer of the floor finish. If using wooden boards for underfloor heating, it is best to use engineered boards, one layer 21 mm. Avoid using wood on top of wood. Maximum 25 […]
Valsir underfloor heating pipes are normally bent without any special tools. When the pipes have been in service and temperature and pressure decrease, the pipe contracts. With an approved fitting range the grip between the pipe and fittings is stronger than the contraction force and does not give any problem provided the installation of the […]
An underfloor heating installation with different pipe loop lenghts and water flow requirements will have different pressure drops for the different loops. In order to achieve an even heat distribution between the rooms in the installation the pressure drop of the different loops must be balanced. In the Underfloor Heating Systems Ltd system this can […]
