Remora Heat Pumps

Remora Heat Pumps for Koi Ponds

Compare individual models for controlled pond heating

Choose a Remora heat pump around your pond’s heat loss, target temperature and installation. The range includes fixed-speed and inverter equipment, with different outputs, water-flow requirements and electrical connections. Compare the exact model rather than choosing from the family name alone.

For a broader comparison, visit our pond heating range or browse all air source heat pumps. Pond-size filters provide a shortlist where supported sizing guidance is available; the final choice should account for your cover, insulation, exposed equipment and local winter conditions.

Choosing a Remora Pond Heat Pump

Fixed-speed or inverter heating?

Remora F models use fixed-speed compressor control, starting and stopping heating as the controller requires. Inverter equipment can vary compressor operation within its working range. Compare these approaches alongside the output at relevant test conditions, your budget and the expected heating duty. Wi-Fi offers convenient access to supported controls, but does not alter the unit’s available heating capacity.

Explore Remora Inverter models and the Remora Professional range. Individual product pages set out each model’s specifications, so you can compare the installation requirements before ordering.

Holding a covered pond at around 12°C

Start with the temperature you want to maintain and the months in which the equipment will operate. Covers and insulation reduce heat loss, while exposed water, filtration and pipework add to the load. Volume alone cannot capture those differences. Include the surface dimensions, pond construction and location when requesting help with sizing.

Remora models are listed under individual sizing advice where a reliable model-specific winter pond-volume guide has not been established. For a covered pond targeting around 12°C, compare the expected heat loss with the exact model’s output at relevant cold-weather conditions. A swimming-pool volume rating or warm-weather kilowatt figure does not establish winter pond capacity. Send us your pond volume, surface dimensions, cover and insulation details, location and target temperature so that the installation can be assessed.

Compare output at the same conditions

A heat pump’s output changes with air and water temperatures. Where the specifications show A15/W26, the test uses air at 15°C and water at 26°C. A warmer-air test describes a different operating point. Compare like-for-like conditions and distinguish heating output from electrical input: the former is heat delivered to the water, while the latter is electricity consumed. COP relates the two at the stated test condition and is not a guaranteed annual efficiency.

Check water flow and the electrical supply

The heater needs its specified flow through the completed water circuit. Allow for pipe length, fittings, filtration and any bypass arrangement. Check the exact connection sizes and leave room to isolate, drain and service the unit. Our pond pump range can help when reviewing circulation, but use the flow delivered through your system rather than a pump’s zero-head maximum.

Electrical requirements differ between models. Some smaller units have a factory-fitted plug, whereas others require a suitable hardwired circuit. Check the exact model’s current and protection requirements with your installer before purchase. A larger heater should not be assumed suitable for the same supply as a smaller one.

Positioning and winter care

Keep the outdoor air path clear and follow the model’s installation clearances. A sheltered position must still allow the equipment to draw in fresh air and discharge cooled air without recirculating it. Provide a stable base, condensate drainage and access for servicing. If the heater is taken out of use during freezing weather, follow its draining and winterisation instructions; switching off alone leaves water inside the exchanger.

Compare the individual Remora F models

These output figures use the same test conditions: air at 15°C and water at 26°C. They support a like-for-like model comparison, rather than predicting heating output on a freezing night. Follow each model’s installation requirements for circulation and electrical supply.
