The examples below correspond to the sizing of ‘standard’ housing units. For installations
known as ‘luxury’ or for specific hot water requirements, please contact the technical
department at Evinox.
The calculated power is the power required at the boiler room outlet. The basic
hypotheses for these calculations tend to the best sizing of the boiler room plant in order to
obtain the best efficiency of annual generation. Under these conditions, the flow
temperature is allowed to undergo a slight drop during the peak hot water period in
extreme winter conditions.
For standard applications the weighting is obtained by using a forfeit value F of 25 kW for
each apartment. Where heat losses are greater than these values, it is the heating power
of the apartment that is used as the basis of calculation.
P1 = losses x 1.05
P2 = F x N x S x 1.05
The upper value of P1 or P2 will be used.
2.11.2 Example 1
Installation of 10 housing units featuring ModuSat TP.
Average heating power 3.5 kW per housing unit.
P1 = [(10 x 3.5 kW) x 1.05 = 37 kW
P2 = 10 x 25 kW x 0.5 x 1.05 = 131 kW
The minimum power required is 125 kW.
2.11.3 Example 2
100 housing units fitted with ModuSat TP. Average losses of 3.5 kW per housing unit.
P1 = [(100 x 3.5 kW) x 1.05 = 370 kW
P2 = 100 x 25 x 0.27 x 1.05 = 709 kW
The minimum power required is 709 kW.
2.11.4 Cleaning
The cleaning of the system must be carried out strictly in accordance with BSRIA cleaning
guidelines and the relevant British Standards. It is necessary to proceed by stages:
Clean the boiler room plant
Cleaning of the primary circuit, with the isolating valves of the ModuSat TP closed
Cleaning of the horizontal pipework and the ModuSat TP satellite
Use the dirt separator in the boiler room and strainer on each ModuSat TP to help in
cleaning the system
The system can then be filled; all the air eradicated by bleeding and adjusting the system
pressure. The system has to be cleaned in accordance with the latest building regulations
BSRIA or British Standards that form part of the design criteria and specification. If the
tender specification does not enforce a particular standard then we would always
recommend the BSRIA standard.
Note: Never leave the system filled with raw untreated water for any length of time.
