Example calculations for expansion equipment<br />
Example 1<br />
Data<br />
- power capacity = 1500 kW<br />
- average heating temperature (90/70ºC) = 80ºC<br />
- static height = 20 metres<br />
- capacity = 15,400 litres<br />
- provision for expansion (vessel) situated at the bottom of the system.<br />
Calculation of vessel capacity<br />
Increase in volume in % = 2.89% ≈ 2.9%<br />
15,400 x 2.9<br />
Expansion volume = –––––––––––<br />
100<br />
= 447 litres<br />
Required expansion reservoir capacity = 447 : 0.8<br />
Your choice<br />
= 558.8 litres<br />
<strong>Flamco</strong>mat GB 600.<br />
Calculation - control unit with pump.<br />
Nominal operating pressure = 2 + 0.5 = 2.5 bar(g).<br />
The 1.5 MW - 2.5 barg point is under the D0 pump curve<br />
(see <strong>Flamco</strong>mat pump characteristics graph).<br />
Selected: <strong>Flamco</strong>mat GB 600/D0.<br />
Example 2<br />
Data<br />
- power capacity = 7000 kW<br />
- average heating temperature (70/40ºC) = 55ºC<br />
- static height = 37 metres<br />
- capacity = unknown<br />
- provision for expansion (vessel) situated at the bottom of the system.<br />
- system components: mixed utility<br />
Calculation of vessel capacity<br />
System capacity calculation = 7000 x 10<br />
= 70,000 litres<br />
Increase in volume in % = 1.42%<br />

Required expansion reservoir capacity = 994 : 0.8<br />
= 994 litres<br />
= 1,242.5 litres<br />
