Rinnai UK
Rinnai is a global leader in heating and hot water appliance manufacturing, striving for reliable and consistent quality. Rinnai specialise in the development of commercial and multi-point water heaters.
Rinnai's quest to develop even safer and more convenient products includes constant study of the fundamentals of obtaining heat from gas.
We strive to improve heating technologies whilst applying the most modern communication and associated management methods, as well as production techniques, across our operations.
We also continue to explore higher efficiencies through cleaner combustion, exemplified in our condensing-type hot water units and pre-mix burner technologies.
Through our innovative H3 initative we are "creating a healthier way of living" with Hydrogen enabled water heaters, Hybrid solutions and renewable technology including Heat pumps.
