Find your pond heater

Use pond size as a shortlist, then read the model description for its recommended volume and operating temperatures. A covered pond at 12°C is our winter planning target; supplier volume guides are not a guarantee for every installation. Contact us for help choosing a model for your pond.

Compare model output, water flow and supply

The output below is measured at air 15°C and water 26°C. It helps compare models at the same published test condition; it is not a freezing-weather output or a guaranteed winter pond capacity. Open the individual page for the full specification and installation requirements.

Temperature and seasonal suitability

The single-phase Jetline manual specifies a 15–40°C heating setting range; the dedicated 155 Tri and 210 Tri manual specifies 8–40°C. Select the exact electrical version and check its controller range. A 12°C setting alone does not establish winter heating capacity: pond heat loss and cold-weather output must also be assessed.

Compare the complete installation

The family combines inverter operation with Wi-Fi control. Rated heating output and efficiency change with air and water temperatures. Pool-volume figures and warm-weather output must not be treated as guaranteed winter pond performance.

Plan the water circuit using the flow required by the heater after allowing for the installed filter, pipes and fittings. Arrange appropriate isolation and service access, and check the electrical supply with a qualified installer. Outdoor clearance and a clear route for condensate are part of the installation, not optional extras.

Covering and insulating the water reduces heat loss. If a heater is shut down during freezing weather, follow its draining and winterisation instructions; switching off power does not remove trapped water. Our pond heating guide explains the main planning considerations.
