Rinnai Hydrogen blend-ready water heaters have a market-leading efficiency of 97% and a modulation range of 13-1 ensuring that gas is only used when needed, these core product functions are supported by scale protection to promote lifetime efficiency and remote monitoring connectivity to ensure the system is always running at its optimum.

Rinnai Natural gas, Hydrogen Blend ready and LPG water heaters are “high output” capable of more than 1500 litres per hour of temperature-accurate hot water whilst also being lightweight and diminutive making transportation and installation simple and manageable without the requirement of heavy lifting gear. The commercial condensing Sensei range only produces small amounts of NOx (27mg /kW) max, meaning that they are one of the cleanest combusting condensing water heaters in the world.
