Rinnai condensing hot water heater units using LPG deliver lower carbon emission figures, greater energy efficiencies and are more economic to run than other sources such as oil or electric, making them the first choice for off-grid installations and sites.
For specifiers and installers, helping an off-grid user select a low NOx energy efficient water heater is critical — and a condensing continuous flow water heater using LPG is one of the most efficient and environmentally friendly options available. By choosing a continuous flow water heater instead of a standard electric water heater, an end user can reduce energy costs by up to 50% and reduce greenhouse gas emissions by up to 61%. When compared with oil-fired systems, this saving is even greater.
Tests show that a Rinnai Infinity condensing water heater emits 35.18mg/kwh NOx compared with a typical oil boiler that emits approximately 364 mg/kwh NOx. That means a Rinnai condensing water heater emits approximately 10% of the NOx that an oil boiler emits, a 90% reduction. Therefore, combining a gas boiler and a Rinnai water heater will radically reduce NOx.
