Product Information

Full details

The Lowara Ecocirc M 25-6/130 is a cast iron central heating circulating pump designed for small to medium domestic properties, offering a robust, reliable, and cost-efficient solution for circulating water in heating systems. Its key benefit lies in its simplicity of use with a single control knob and multi-color LED status indicator, alongside efficient operation with a low power consumption. A potential caveat for some users might be its maximum 6-meter head, which may not be suitable for larger or more complex heating systems.

FAQs

What is the maximum head pressure of this pump?

The Lowara Ecocirc M 25-6/130 has a maximum head of 6 meters.

What are the three operating modes and when should I use them?

The modes are Proportional Pressure (for TRVs), Constant Pressure (for underfloor heating), and Fixed Speed (for boiler feed/single-pipe systems). Select the mode best suited to your specific heating system configuration.

How do I know if the pump is working correctly?

The multicolor LED indicator on the pump face shows the status. A solid green light indicates the circulator is working properly.

Is this pump suitable for domestic hot water systems?

No, this pump is specifically designed for circulating water in central heating systems and is not suitable for potable hot water applications.

What does a blinking green LED mean?

A blinking green LED indicates that the automatic air-purge function is currently running.

What is the power consumption of this pump?

The pump has a low power consumption with a maximum power limit of 34W.

What is the port size and port-to-port dimension?

The port nominal diameter is 25mm, and the port-to-port dimension is 130mm.

How often should I perform maintenance on this pump?

The pump requires minimal maintenance due to its design and automatic air-venting. However, regular checks of the central heating system and keeping the pump exterior clean are recommended.

Troubleshooting

Pump is not running

Check the electrical connection and ensure the power supply is active. Verify that the pump is not in standby mode (indicated by a blinking yellow LED) and that the system has power. Ensure the pump is not showing a red 'failure' light.

No circulation or poor heating

Ensure the correct operating mode and speed are selected for your system type. Check for air in the system; the automatic air-venting function should address this, but manual bleeding of radiators may be necessary. Verify that no valves in the system are closed and that there are no blockages in the pipework.

Pump is noisy

Noises can indicate trapped air in the system. Allow the automatic air-purging function to operate, or manually bleed radiators. If the noise persists, check for blockages or debris in the impeller (requires professional service).

Red LED indicator is lit

A red light indicates a pump failure or a dry run condition. Check the electrical supply and ensure the pump is submerged in water (not running dry). If the issue persists, consult a qualified heating engineer as internal components may require inspection or replacement.

Pros and Cons

Pros

  • Energy-efficient operation with a low EEI.
  • Versatile with three selectable operating modes for different heating systems.
  • Simple to operate and monitor thanks to the single control knob and clear LED indicator.
  • Automatic air-purging feature simplifies maintenance.
  • Compact and lightweight design facilitates easy installation.
  • Durable cast iron construction ensures reliability.

Cons

  • Maximum head of 6 meters may be insufficient for larger or multi-story properties.
  • Cast iron body may be heavy for some installation scenarios.
  • Limited to central heating systems; not suitable for potable water circulation.
  • Control knob might be less precise than digital interfaces for some users.
  • Requires manual selection of operating mode based on system type.

Setup, Compatibility & Care

Setup:

  1. Installation Location: Install the pump in a dry, accessible location within the central heating system piping. Ensure it is installed in the correct orientation as per the manufacturer's guidelines (often indicated by an arrow on the pump body).
  2. Connections: Connect the pump to the system using appropriate fittings for its G 1 1/2" or R 1" connections. Ensure all pipework is clean before connecting.
  3. Electrical Connection: Connect the pump to the mains power supply according to local electrical regulations. Ensure power is isolated before making any connections.

Compatibility:

  • System Type: Primarily designed for central heating systems, including those with thermostatic radiator valves and underfloor heating.
  • Property Size: Suitable for small to medium domestic properties requiring up to a 6-meter head.
  • Pipe Size: Compatible with 25mm pipe nominal diameter and has a port-to-port dimension of 130mm.

Care:

  • Cleaning: Keep the exterior of the pump clean by wiping it with a soft, damp cloth. Avoid using abrasive cleaners or solvents.
  • System Maintenance: Regularly maintain your central heating system, including bleeding radiators and checking system pressure, to ensure the pump operates under optimal conditions.
  • Obstructions: Periodically check the system for potential blockages that could affect pump performance. The automatic air-venting function helps manage air, but regular system checks are still recommended.
