PEX Fittings from Uponor Wirsbo Quick & Easy ®
Quick & Easy Connection is designed for installation of PEX pipe Uponor Wirsbo-PEX (evalPEX). This unique combination is based on the increased elasticity and molecular memory of the material of PEX pipe and rings, own crimp PEX fitting after expansion in the cold. Installation of the system is quick and easy, requires no special expensive [...]
Floors are concrete solutions
Concrete floor PEX radiant heating with defined as “wet” performance of floor PEX radiant heating system. It is very important that the concrete was not air bubbles, and especially around PEX pipe. There are several methods of laying underfloor PEX radiant heating with a concrete solution. Minimum thickness of concrete above the mud tubes should [...]
Standard insulation foam (certified by the influence of sound) may be subjected to a load of 20 ÷ 36 kg / m 2, ie polystyrene PS 20 and PS 30. Other types of isolation, admitted in terms of permeability of sound, can withstand loads of up to 5 kg/m2. Hydronic heating floor PEX radiant heating [...]
Floating wood floors
Floors of this type are arranged on wooden floor beams. Between the joist is the insulating layer of material that prevents the flow of heat down. A layer of insulation 10 cm thick, densely fills the space between the beams. By reinforcing bars nailed across the wooden slats. These floors do not contain any concrete [...]
PEX radiant heating
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 [...]
PEX radiant heating system
It should be remembered that the heated floors give warmth in the downward direction (approx. 10%). This heat flow should be considered when determining the total flow of water in the PEX radiant heating system, as well as the selection of the heat source. In areas with particularly high demand in the warmth associated with [...]
Installation of PEX pipe
Choosing the correct distance between the PEX pipe according to the following table provides an opportunity for individual selection of a single heat requirements for each room. Heat demand [W/m2] The distance between the loop [mm] needed tube [m/m2] Application area approx. 100 75 13,3 bathrooms coastal zone 90-100 150 6,6 band stay 75-90 225 [...]
