1. Plate Heat Exchanger
 To start, we need to know the KW required to meet the demand from the central heating circuit to start calculating the most suitable PHE

2. System Control Panel
 The control panel will sense the secondary flow temperature leaving the plate heat exchanger and send a signal to the modulating 3 or 4 port valve to close or open depending on demand

3. Primary
 3 or 4 port valve This valve will open or close as demand (temperature) increases or decreases on the secondary flow out of the PHE

4. Primary
Heating Pump This pump will circulate water at the correct design flow rate

5. Secondary
 Radiator Circuit These can be radiators or any heat emitters including underfloor heating

6. Secondary
 Cold Feed & Mains Kit This is the point where fresh water enters the heating circuit to replenish lost water

7. Secondary
 Heating Pump This pump maintains the correct flow between the cylinder & PHE

8. Secondary
 Temperature Sensor This will sense the DHW flow temperature out of the PHE to the outlets and tell the control panel to open or close the 3 or 4 port valve allowing more or less hot water through on the Primary side of the PHE

9. Secondary
 Non Return Valve This will stop fresh water from going backwards into the heating circuit

10. Boiler or Primary heat source
This can be a boiler or any heat source that can generate the KW required to boost the secondary heating circuit
