Cloverleaf Pond Heater

– EU, TUV & UL approved.
– Models Available: 1kw, 2kw All fittings, threads and hose sizes are identical making them interchangeable.
– IP55 Rated weatherproof
– Optional rigid or flexible pipe connections
– Easy temperature control
– 1.5m Cable length
– Includes low pressure flow switch


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 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.

  • Product Review - I have this running on a 450gall tank (in an open-fronted barn) via 10,000L/h varipump and Tempest on 2" waste pipe (pump fed), everything as insulated I can manage! It's pretty neat and seems good quality. Controls are straightforward. The manufacturer's minimum flow rate for this pump is now 2,000L/h (used to be 4,000 but there's a sheet in the box explaining the change). You don't feel it giving out heat (you can only go by the light that comes on), which is a bit disconcerting to start with, but I left mine on overnight (no fish, pump rate set low) and that brought the temp from 8C to 12C, then a few hours later up to 15C. The mounting plate is a little frustrating, you'll have to pad it up off the surface. I used 2" rubber boot connectors to join it - and I've also built in a ball-valve controlled bypass so that in summer when I don't need heating I will have unrestricted flow (the element sticks down into the water so restricts flow a little - if I open up the additional pipes there's a noticeable increase in flow). I had wondered whether 1kW would be enough but it seems fine for this size and in my indoor location.
