Elecro Koi Pond Heaters

At the Elecro facility in Hertfordshire, England, premium parts and materials are used to make the pond heaters. The structure is made up of a flow tube with inlet and outlet mouldings made of a specifically mixed polymer alloy material.

A reversible flow switch with a gold-tipped reed switch and a titanium fulcrum pin—which permits water input from either direction—is accommodated in the outlet moulding. By guaranteeing complete immersion of the elements, the inlet moulding significantly lowers the possibility of air locking.


The two movable swivel feet that hold up the Elecro pond heaters allow either wall or floor mounting. The front face of the electrical enclosure houses the heater control components.
