Covered-pond size guide

Our estimated 12°C winter shortlist: up to 5,000 litres. This assumes an insulated pond with a suitable cover. We use complete size bands within the supplier’s 9,000-litre guide for 15°C winter holding. Using a lower target reduces the heating demand; this is our selection estimate, not a manufacturer guarantee at every winter temperature.

Allow for your local winter weather, exposed pipework and filters, surface area and insulation. An uncovered or exposed pond can need a larger heater even at the same volume.

Controlled heating and cooling with built-in Wi-Fi

The i9 is the entry model in the Remora Inverter family, with a relatively compact cabinet and a factory-fitted mains lead. It is a sensible model to compare where the heat-loss assessment calls for modest output and the water circuit can provide the specified flow. Its lower purchase price should not be the deciding factor if your target is continuous winter heating rather than seasonal assistance.

Built-in Wi-Fi works with the Smart Life app, allowing remote temperature and mode adjustments. The inverter system varies compressor and fan operation within its working range instead of operating only at one fixed output. Select the heating plan around the needs of your pond or pool, and use the controls to maintain it consistently.

For koi keepers, the first decision is what you want the heater to achieve. Holding a covered pond at a moderate temperature during winter is a different job from warming the water earlier in spring. Use the published specifications alongside your pond’s heat requirement when choosing the model.

Choosing it for a covered koi pond

If your aim is approximately 12°C through winter, tell us the pond volume, surface dimensions, construction, cover arrangement and location. Include any exposed filter chambers or long external pipe runs. Two ponds containing the same number of litres can lose heat at very different rates, so volume is a starting point rather than a complete sizing calculation.

The output figures above also show why the model name should not be treated as a guaranteed winter heating output. Published performance changes with the test conditions. Neither of those figures is a specific prediction for a cold night with the pond at 12°C. A winter recommendation needs to allow for the local conditions, heat loss and time spent defrosting. For a winter recommendation, provide the pond dimensions, cover details, location and target temperature so the heater can be matched to the heat loss.

For spring and autumn use, explain when you intend to start heating and the temperature you want to maintain. A heater selected for modest seasonal support may not have enough reserve for continuous winter duty or a higher target temperature. Resolve that choice before comparing purchase prices, as the most economical installation is one selected for the intended job.

Understanding inverter operation

Inverter control allows the compressor to vary its operation as demand changes. During a recovery period the system may need more output; closer to the target, it can reduce its output within its operating range. That does not make running cost a fixed number. Weather, heat loss, water temperature and the amount of heating required all influence electricity consumption.

Heat output and electrical input are different measurements. When comparing pumps, use figures measured under the same air and water conditions. A headline efficiency figure obtained in warm conditions should not be used to estimate the whole winter electricity bill. A pond cover and insulation should be considered alongside the heater rather than added as an afterthought.

Water flow and installation planning

Plan the water circuit so that the heater receives the specified flow. The circulating pump, pipe diameter, fittings and any bypass arrangement all affect what reaches the heat exchanger. Do not assume the pump’s advertised maximum flow is the flow through the installed heater. Include suitable isolation and service access so maintenance does not require dismantling the surrounding filtration.

Before ordering fittings, check the exact supplied union arrangement against the installation manual and the pipework already on your pond. Provide space to disconnect the water connections and to drain the equipment when necessary. A bypass can be useful for setting the heater branch flow and for servicing, but it must be arranged to suit the actual system.

Outdoor siting and electrical connection

Choose a firm, stable outdoor position that leaves the manufacturer’s required clearances around the unit. Keep the air inlet and discharge clear of close fencing, vegetation and stored equipment. Enclosing a heat pump without a designed airflow route can cause it to draw its own cooled discharge air back in, reducing its ability to collect heat.

Allow for condensate drainage as part of the installation. Water produced during normal operation needs somewhere suitable to go without creating a slippery path or collecting around the base. Leave enough access for inspection and cleaning, as well as for opening service panels.

The i9 is supplied with a 2.8 m mains cable and UK plug. Use a suitable RCD-protected outdoor supply and follow the installation manual. Have the existing circuit checked where necessary; the presence of a plug does not establish that a socket shared with other equipment is suitable.

Modes and remote control

The range offers Powerful, Silent and Smart operating modes. Select a mode to suit the heat demand and the installation rather than assuming the quietest setting will meet every load. Make sure the Wi-Fi signal reaches the chosen position before relying on remote control. Local inspection remains important even when the app is available.

Daily use, monitoring and winter care

Make temperature changes gradually and monitor the pond with a suitable thermometer. App access is useful for checking settings, but it is not a substitute for inspecting water circulation, the pond and the equipment. If the heater stops, investigate the cause and follow the fault guidance before changing settings repeatedly.

Keep the air path clear and inspect the drainage route regularly. If the heater will be taken out of service during freezing conditions, follow the manual’s draining and winterisation instructions. Switching the electrical supply off alone does not remove water trapped inside the heat exchanger. An idle unit and an actively heating installation require different winter arrangements.

Comparing the next model size

Compare the i9 with the other sizes in the Remora Inverter range. Look at the output under matching test conditions, the required flow and the electrical requirements, not simply the number in the model name. Contact us with your pond details if you need help choosing between sizes before placing an order.

Pond size shortlist

Use the estimated covered-pond shortlist near the top of this page, then check the assumptions against your pond. The supplier sizing guide explains how covers, insulation and target temperature affect demand. Our estimate uses complete volume bands within that guidance; it is not a guarantee for every site or winter. Exposed pipework, filter chambers, surface area and local weather can increase the heating duty.

Rated heating output is measured at the stated air and water temperatures. In these figures, A means air temperature and W means water temperature, both in degrees Celsius. Heating output is not electrical consumption or a guarantee of winter performance. For a koi pond, compare the minimum water setpoint and cold-weather output as well as the headline kW rating.

Electrical supply and UK socket connection

Maximum current: 6.8A.

The UK brochure specifies a 13A plug connection for this model. Use a suitable protected UK socket and follow the installation instructions; the current figure alone does not establish which cable or plug is included.
