Water heaters are renewables ready
Rinnai’s HDC1500 and HDC1200 condensing continuous-flow water heaters are renewables ready when required. They can easily be retrofitted to integrate with solar thermal or heat pumps. For example, a water heater used as a solar gas booster only fires when the desired temperature cannot be reached by the renewable-heat source. The rest of the time, the water heater is inactive.
These water heaters guarantee continuous hot water at any time of day or night.
