Rinnai Commercial Water Heaters

Rinnai were the first to innovate the continuous flow unit into a manifold pack and later to develop combination continuous flow with a low heat loss 316 Marine Grade Stainless Steel storage tank.

Rinnai now has a dedicated Heavy Duty range of continuous flow gas heaters that feature more resilient heat exchangers as well as a host of other features. The exceptional quality of our products is reflected in their extended warranty period.

Rinnai is still the No. 1 choice for systems using continuous flow hot water. Today our products are even more sophisticated - designed with the environment in mind, with high efficiency low emission burners and low tank heat losses.
