The new generation REX instantaneous indirect water heaters are engineered for high heating efficiency. REX heaters use the boiler to heat domestic water instantly upon demand. As the boiler water enters the tank (not the coils) it is stored, ready for a domestic water call.

REX heaters also act as a buffer tank to eliminate boiler short cycling. The boiler water is circulated in a closed loop system, thus extending boiler life.

The REX indirect instantaneous system offers high efficiency, long life and an economical way of heating domestic water as there is no stagnant water in the coils. It virtually eliminates bacterial growth.
