Rinnai water heater achieves very low Nox
Rinnai’s latest Infinity 1600i condensing low-Nox water heater has been tested to below 20 ppm (Nox). In commercial test areas incorporating flow and return systems, the units have recorded Nox levels as low as 7 ppm. These water heaters have a downward-firing pre-mix burner and continuous optimisation of gas input using intelligent integral controls. Maximum output is 54 kW, with modulation down to 4 kW.Up to 37 l/min of temperature-controlled hot water can be delivered.
The heaters are renewables ready and can be used to boost the temperature of water that has been preheated by solar-thermal and heat-pump systems.
