In the design of underfloor PEX radiant heating for a given quantity of PEX radiant heating surface, ie floor surfaces are counting parameters of PEX radiant heating water, given the need for heat in the room temperature resistance of the layers of the floor to accepted values?
Calculation of floor radiant heating – a system Uponor Wirsbo
Terms of proper design of floor heating system are:
* Compliance with the standard PN-91/B-02020 – Thermal protection of buildings.
* Calculation of heat requirements according to EN ISO 6946 (provisionally, according to German standard DIN 4701) – QN.
* Calculation of heat requirements for the premises at a reduced amount of heat loss through the floor QPd. Q = QN – QPd
* Calculation of heat flow for the premises:
APd – the floor surface in the room [m2]
