1.1 Application
The Aqua Line heats a room by means of radiant heat. Warm water is pumped through the
pipes in the radiant panels. This makes the panel warm and heat is then radiated. The Aqua Line
can also be used for cooling: cooled water is pumped through the pipes making the panel
cold and cooling the environment. Condensation must be prevented from forming. The minimum
water temperature therefore depends on the level of atmospheric humidity in the room.
Subject to change
The manufacturer is committed to constantly improving its products and reserves the right to
make changes in the specications without prior notice. The technical details are considered
correct but do not form the basis for a contract or warranty. All orders are accepted according
to the standard terms of our general sales and delivery conditions (available upon request).

1.3 General warnings
Incorrect installation, adjustment, alteration, maintenance activity or repair may lead to material
or environmental damage and/or injuries. The appliance should therefore be installed, adapted or
converted by a skilled and qualied installer, taking into account national and international
regulations. A faulty installation, adjustment, alteration, maintenance activity or repair shall render
the warranty void.
1.4 Description of the Aqua Line panel [3]
A radiation panel is made up of multiples of four pipes attached to a proled steel plate. Because
the pipes are actually located within the prole of the steel plate, there is a large contact area.
This also benets the delivery capacity. The top of the radiation panel should be insulated on the
upper side using the loose insulating material supplied (to be tted by you). This will restrict
undesirable upward radiation. The insulation strips must be cut to length manually.
1.5 Construction of the panel [3]
1 Reector
2 Water-carrying pipe
3 Distributor
4 1” connections, water side
5 Mounting set (prole and carbine hooks)
6 Push-on connectors (optional)
7 Insulating material
8 De-aeration connection ½” (de-aeration nipple is not included in MHS’s scope of supply)
The panels are delivered in standard lengths of 4 or 6 metres. Longer lengths can also be created
by joining the panels together using the push-on connectors [3]. Note the water ow in this case.
In addition to the length, the width can also be adjusted. The distributors are also installed using
the push-on connectors. If required, the push-on connectors can be concealed using a reector
concealing cover to create a neat nish [4].

2.0 Selection and design advice [5]
In order to heat the room evenly, it is important to follow the steps below. These calculations
determine the type of panel, the panel length, distributors and the pressure drop. In connection
with the water side pressure drop and panel expansion, we advise you to keep the maximum
section length below 46 metres.
2.1 Signs and symbols
B = Width of the room q = Panel heat output per section length
H = Height of the room Q = Heating requirement
Hm = Installation height Tomg = Ambient temperature
K = Upper temperature Twi = Water temperature in (feed)
L = Length of the room Twu = Water temperature out (return)
LB = Section length ∆T = Temperature variation
Ltot = Total section length Qpp = Heat capacity per panel (table) [6]
nsp = Number of radiation sections npp = Number of panel lengths needed
n = Number of pipes per group R = Pressure drop per pipe per metre of panel
mpb = Mass ow per pipe Z = Distributor pressure drop
m = Mass ow per panel length
2.2 Steps to be followed
1. Determine the width, height and type of panel for the space. [5]
Twi = 65ºC
Twu = 50ºC
Tomg = 18ºC (Temp. in the room)
2. Determine the section length: [5]
LB = L – 3m
L
B = 45 – 3 = 42m
NOTE!
Only 4 or 6 metre panels may be used.
42m is divisible by 6. This results in 7 panels, each 6 metres in length
See table [9]
3. Determine the installation height:
Hm= H – 0.5m
Hm = 5 – 0.5 = 4.5m
This is also the optimal distance from the centre point of each panel. [5]
5
EN

4. Determine the upper temperature:
Twi + Twu
k = ————— – T omg
2
65 + 50
k = ————— – 18 = 39 Kelvin
2
This value can be used to look up the heat capacity of the panel in the table (heat delivery
table) [6] (type 1,2,3 and 4). This is the value Qpp.
(T=1) Qpp = 132 W/m (heat output table) [6]
5. Determine the heat delivery for a single length:
q = LB x Qpp
q = 42 x 132 = 5544 W/section
6. Determine the temperature variation of the water:
∆T = Twi – Twu
∆T = 65 – 50 = 15 K
7. Determine the mass ow of the liquid in one panel length:
m = (q/∆T ) x 0.86
5544
m = ———— x 0,86 = 318 kg/h
15
8. Determine the mass ow per pipe:
mpb = m / n
1 section consisting of a Type 1 panel. [2]
Flow may take place through 4 pipes or 2 pipes. The mass ow must be calculated for these
two situations in order to connect the panel on the water side.
mpb = 318 / 4 = 79,5 kg/h (B)
318 / 2 = 159 kg/h (A)
9. Check the minimum mass ow using the appropriate table [7] (68 kg/h). The calculated value
must be higher in order to achieve turbulent ow through the pipes. This then gives the
correct number of distributors [2].
6
10. Determine the pressure drop on the water side [2]:
T1 Single side Sit.A ∆P = (Lb x R1) + (Lb x R2) + Z
T2 Single side Sit.A ∆P = (Lb x R1) + (Lb x R2) + Z
T3 Single side Sit.A ∆P = (Lb x R1) + (Lb x R2) + Z
T4 Single side Sit.A ∆P = (Lb x R1) + (Lb x R2)+ (Lb x R3) (Lb x R4)+ Z
T1 Alternating sides Sit.B ∆P = (Lb x R1) + Z
T2 Alternating sides Sit.B ∆P = (Lb x R1) + Z
T3 Alternating sides Sit.B ∆P = (Lb x R1) + (Lb x R2)+ (Lb x R3) + Z
T3 Alternating sides Sit.C ∆P = (Lb x R1) + Z
R = Water resistance per panel length in Pa/m
Z = water resistance in Pa for both distributors
R = x 196
Calculation example: T=1 , 79,5 kg/h (B)
∆P = LB x R +Z
R = 41 Pa Z = 202 Pa
Determine the pressure drop for both panel groups:
∆P = 42 x 41 + 202 = 1924 Pa
3.0 Transport
Leave the panels on the pallet for as long as possible.
Ensure the pallet does not bend too much (do not move the pallet using a pallet truck).
To prevent bending, move the panel rotated/turned by 90º [8].
Panels must be stored in a dry environment.
4.0 Mounting panels [9][10]
4.1 Mounting instructions [9]
– The panel must be placed at a minimum height of 2m above the oor.
– The measurement from the centre point of the panels must not be greater than the height
above the oor. [5]
– Distance between the installation proles max. 2 metres [9].
– Suspend the panels in such a way that they can expand freely lengthways [9][10].

l2 = Expansion in mm
l1 = Section length mm
α = Linear expansion coefcient of steel => 11.7x10-6
Tw gem = Average water temperature.
Tomg = Temperature in the room.
Determine the expansion of 1 section length:
l2= l1 x (1 + α x (Tw gem – Tomg)
l2 = 42000 x (1 + 11.7x10-6 (57.5 – 0))
l2 = 42028.3mm
Expansion U = 28.3mm
Expansion table [11].
4.2 Order of installation. [4]
– Fit the suspension points [9][10]
– The panels can be mounted directly to threaded rod or hung from chains [12].
– Join the panels together using the push-on ttings.
– Install the distributors [3].
– Add the insulation.
– Place covers, if required, on the panel connections and distributors [4].
5.0 Start-up
Fill the installation with water, bleed the pipes and rinse through to remove any contamination.
Adjust any ow controls. Ensure that the water mass ow does not fall below that indicated in the
table [7]. If the water mass ow is lower, output cannot be guaranteed.
Key table [7]
TR = water return temperature in °C
W = minimum mass ow of water per pipe in kg/h
6.0 Maintenance
Clean the panels regularly, check them for leaks and check the suspension points. If applicable, ask
a qualied installer for maintenance advice.
