Rena Smart Heater uses an elliptical heating casing,(instead of the traditional round glass test tube), which is made from a virtually unbreakable plastic material.

The precision electronics allow heater settings of 1/2 degrees from 20 deg C to 34 deg C.

A central by-pass core allows this heater to be connected to the inlet of an external filter (using the connection kit which is available separately)whilst the supplied bottom strainer prevents debris or fish entering the heater by-pass core
