Heat Pumps

Maintain stable pond temperatures year-round while drastically reducing your running costs with our range of high-efficiency air-source pond heat pumps, full-inverter heating units, and climate controllers. Engineered specifically for dedicated koi ponds, large aquatic facilities, and outdoor fish systems, heat pumps offer the most energy-efficient, environmentally friendly method to heat and cool your water with precision.

Our collection features advanced full-inverter heat pumps that automatically adjust compressor and fan speeds to match the exact thermal demand of your pond. Operating with high Coefficients of Performance, these units extract renewable ambient heat from the outside air and transfer it directly into your circulating water, delivering up to five times more heat output per kilowatt of electricity than conventional direct electric heaters. Built with pure titanium heat exchangers housed in weatherproof, corrosion-proof composite casings, they withstand continuous outdoor exposure, therapeutic salt treatments, and pond medications with zero risk of internal corrosion. Many models operate seamlessly in freezing ambient air temperatures down to sub-zero conditions and feature reversible cycles to prevent summer overheating, alongside built-in Wi-Fi connectivity for convenient smartphone monitoring and temperature adjustments from anywhere.
