UltraZap pond water heaters keep the water warm through cold spells, with a built-in thermostat that cuts the element in and out to hold your set temperature.

The 2kW model suits ponds up to about 8 000 litres, and the 3kW adds more heating power for larger or colder setups — for koi ponds, ornamental ponds and large aquariums or fish tanks where stable temperature matters.

– Built-in thermostat for steady control
