Pond heaters

[ember04]

Can anyone recommend a good heater for a patio pond? I have a 68-gallon pond and need a heater that can go outside and keep the water at about 15 degrees celsius all year round

is the pond insulated?
if it isn't, any heater will struggle when it gets really cold.

The pond is a plastic plater (it is an above-ground patio pond)

Put a piece of polystyrene foam under it and around the outside of the pond. Use foam that is at least 2 inches thick.

Put a cover on the pond. Either glass or Perspex. Perspex is lighter and safer than glass. You can also put a sheet of bubblewrap on the surface of the pond but only cover 80% of the surface so there is some air exchange.
