The relatively compact footprint of all Rinnai units and systems means it can optimise plant room space and safeguard accessibility for maintenance and servicing. There is huge potential for on- demand style water heaters such as the Rinnai HDC 1200i units to play their part in new build and in refurbishments projects alike, where in the latter there are still many old systems that need replacing. By replacing this older technology with new condensing appliances will help support the UK drive towards greener industry. The Rinnai Infinity HDC 1200i water heater uses heat exchanger technology to allow the largest capacity flow rates, thereby guaranteeing all the hot water needed, when it is needed. As well as increasing capacity, the Rinnai Infinity water heater has lower greenhouse emissions because of the new reduced NOx burner technology and as there is no storage, this scores well with BREEAM. Available in both internal and external versions, HDC 1200i gives end users 107% net efficiency as the condensing process delivers up to 95% thermal efficiency, translating 65 into significant energy savings when compared to standard tankless water heaters. With a continuous flow water heating unit, it will deliver limitless amounts of useable hot water, whatever the site - school, hospital, hotel, office blocks, leisure club etc with no fluctuations in water delivery temperature. The only time the site uses energy to heat water is when there is a demand, in other words, it is only burning gas when a tap or shower is being run.
