Water heaters

A range of water heaters of varying strengths for heating you aquatic and semi-aquatic enclosures. Great for heating the submerged sections of turtle and amphibian enclosures. These heaters are self regulated and can be used to warm entire aquariums. The general rule is 1W can service 1L of water and we have included a range of wattages to ensure we can provide an appropriate water heater for most aquariums. In large enclosures it is advisable to place a heater at each end to ensure the water is heating evenly and one heater is over working.
