Challenge
- Hydronically unbalanced or poorly balanced system, low efficient heat consumption on the secondary side and oversized control equipment increase the return temperature.
- Low ΔT between flow and return lead to increased pumping cost, high leakages, high heat loss, poor COP for CHP and bigger CO2 emissions.
- This reflects in increased distribution and operational costs and higher primary energy generation costs.
Benefit
- Stable differential pressure enables balance between temperature and flow
- Heat production and system efficiency are maximized
Virtus.
Virtus pressure and flow controllers for a efficient hydronic balancing and precise temperature control
Stable control, no oscillations and flow delivered up to the real need results in low ΔT which can reduce 3-5% of primary energy generation cost
Features:
- Perfect control and stability
Challenge
- Oscillations on the primary side results in unstable secondary side temperature at the consumer
Benefit
- Eliminated network pressure variations (network disturbances) prevent oscillation on the primary side and ensure stable conditions for the secondary side application

Virtus pressure and flow controllers for efficient hydronic balancing and precise temperature control
Stable control, no oscillations and flow delivered up to the real needs results in high ΔT which can reduce min 1% of primary energy generation cost for each 3K of ΔT increase.
Features:
- Perfect control and stability
Challenge
- Too much heat delivered - more than consumed, as a consequence of unbalanced or poorly balanced system, missing flowrate control and oversized control equipment
Benefit
- Exact heat is delivered – according to the consumer need and an agreement
- Providing the best quality of supply
Virtus.
Virtus PICV pressure independent control valves and flow limiters prevent to exceed the max flow
Stable control, no oscillations and flow delivered up to the real need results in low ΔT which can reduce 3-5% of primary energy generation cost
Features:
- Perfect control and stability
- iSET
Challenge
Poor network planning and dimensioning leads to
- Water and heat losses
- Shift of critical points in network,
- Flow overcapacity
- Higher pump head than actually needed
This reflects in higher heat production costs and higher investment.
Benefit
Optimal network design reduces the heat loses and pumping costs. It enables prioritized investments and economical network upgrade. It reduces costs by maximizing consumption density and right dimensioning. Critical points in the system are under control and flow is delivered according to the needs and contract.
