Using the system k
H
value to calculate the system heat output:
q = k
H
x (T
water
– T
air
)
Example:
The heat output through an 18 mm thick, ≈ 1.25 tog timber oor, over
Econna-12 with 6 mm ply, tted with pipe at 150 mm centres, in a 21°C
room heated with 40°C water is;
q = 2.30 x (40 – 21) = 2.30 x 19 = 43.7 W/m²
Alternatively, using the system k
H
value to calculate the required water
temperature, knowing the required heat output:
T
water
= ( q / k
H
) + T
air
Example:
The water temperature required to produce a heat output of 55W/m²,
through a 3 mm thick ≈ 0.25 tog LVT oor nish, over Econna-12 panels
with 6 mm ply, tted with pipe at 150 mm centres, in a 22°C room is;
T
water
= (55 / 3.11) + 22 = 18.5 + 22 ≈ 40.5°C
q = Specic Heat Output, W/m² k

= System Performance Factor, W/m²K
