The Wilo Yonos PARA ST 15 7.5 RKC is a high-efficiency circulation pump for homeowners and professionals managing solar thermal and heating systems. Its key benefit is providing reliable water circulation with significant energy savings. A potential caveat is its manual control system, which requires user adjustment for optimal performance. This pump offers powerful circulation, durable construction, and flexible control options to ensure efficient heating system operation.

The primary advantage is its high energy efficiency, indicated by an Energy Efficiency Index (EEI) of ≤0.21, which helps significantly reduce electricity consumption compared to older pump models.
The pump features Wilo Red Knob technology. Simply turn the red knob to select between variable pressure operation or constant speed settings based on your system's requirements.
Yes, the Wilo Yonos PARA ST 15 7.5 RKC is designed to work reliably with water glycol mixtures, commonly used in solar thermal systems, up to a concentration of 50% glycol.
The pump has a maximum delivery head of 7.6 metres and a maximum flow rate of 4.0 cubic metres per hour.
The pump is constructed with durable materials like cast iron with corrosion protection, stainless steel, and reinforced composite, designed for long-term reliability in heating and solar thermal systems.
It is well-suited for most standard heating and solar thermal systems that require reliable circulation and benefit from energy savings. Ensure it meets the specific flow and head requirements of your system.
Yes, the pump includes integrated motor protection to ensure safe continuous operation and prevent damage from overheating.
Check that the power supply is connected and the circuit breaker is on. Ensure the system has water and there are no airlocks. Verify the pump is not set to 'off' or a minimal setting.
Check for blockages in the system's pipes or filters. Ensure the pump's speed setting is appropriate for the system's needs. Air in the system can also reduce flow; bleed the system.
This could indicate cavitation (air in the system) or a foreign object in the impeller. Bleed the system to remove air. If noise persists, the pump may require inspection or professional service.
Ensure adequate ventilation around the pump. Check for system blockages that could cause the pump to work harder. The integrated motor protection should prevent permanent damage, but the cause of overheating needs to be addressed.
