Installation examples:

1.


Heat source:
Solid fuel boiler.

Buffer tank loading from the boiler:
anti-condensing pump unit M2 MIX3 CS DN32;
Δt 20 K.

Buffer tank loading from the solar system:
Version 1: employment of a solar thermal pump unit S2 Solar 30 and of an unmixed pump unitM2 DN25, with the interposition of a heat exchange unit S2 Exchange.
Version 2: employment of a solar thermal pump unit Solo 2 for stratified loading.

HDW users:
ModvFresh 4 pump unit with recycling line.

Distribution: heating distributor K251.4/125 DN25 for 4 pump units.

Heating users:
- Medium power radiator line, Δt 20 K:
mixed pump unit CLIMA 3 DN25;
- Low power radiator line, Δt 20 K:
mixed pump unit M2 MIX3 DN25;
- Low power under floor heating line, Δt 8 K:
fixed temperature pump unit M2 FIX3 DN25;
- Medium power wall radiant heating line, Δt 8 K: employment of a heat exchange unit M2 Exchange to separate from the hydraulic point of view the users line (to keep the piping clean). Unmixed pump unit M2 DN25 on the primary line and mixed pump unit M2 MIX3 Energy G21 DN25 on the secondary line, to meter the produced energy.

 

2.


Heat source:
Solar and geothermic energy.

Version 1: forced circulation solar thermal installation with the employment of a solar pump unit S1 Solar 10 to load a HDW tank.
Version 2: natural circulation solar installation with the employment of solar collectors with HDW tank included.

Distribution:

Solar Kit 1, solar-boiler connection kit, to mix users’ HDW.
