EU, TUV & UL approved.
Models Available: 1kw, 2kw All fittings, threads and hose sizes are identical making them interchangeable.
We suggest that, on average, 1kw of power is suitable per 1000 gals (4450ltrs) of pond water in most instances.
These new models are compact and easy to use both models are supplied with couplings and hose tails to connect to either rigid 1.5" pipe or 3/4" to 1.5" semi rigid pipe, it is recommended to use the largest size pipe feed your pump will allow to make sure of sufficient pressure to operate the internal flow switch. Temperature is controlled by adjusting a dial to the required temperature setting. A minimum water flow of 4000 Liters an hour is required at the heater to operate the built in safety flow switch which in the event of the pump stopping shuts the heater off to prevent damage to the heater.
Additional helpful installation information.
For maximum efficiency and to maintain an ambient temperature the pond should be covered and insulated to help achieve and maintain the pond temperature in cases of insufficient insulation more KW per gal/litre may be required depending on the level of desired water temperature. it is suggested to use a maximum pump delivery of 6000Liters an hour to maximize efficiency, unlike a conventional water heater pond heaters gradually heat the water on each pass so running too fast is less efficient, it will take several hours to reach the required set temperature when first used, if the pond is insufficiently insulated it may not be possible to achieve the desired set temperature or maintain a stable water temperature.
These heaters are designed to be pump fed and will not work on a gravity return.
The Heater should ideally be installed at the end of the water return to the pond after Ultraviolet steriliser's and filters such as all in one pressure filters to reduce excessive water back pressure in the heater, the maximum working pressure is 0.3mpa and should not be exceeded as this may lead to water ingress into the electric's of the unit voiding the warranty in the case of failure due to water damage.
