Rinnai UK introduced the new HDC 1200i continuous model, for use on all high demand commercial sites.

It can deliver in excess of 1560 litres per hour and guarantees unparalleled levels of efficiency and hot water delivery for the end user, whilst streamlining installations and guaranteeing future regulatory compliance.

This precision engineered water heating unit can also be combined as multiple units into one single, easy to handle module incorporating cascade frames and common flue.

Both the HDC 1200 internal and external models turn in a market leading energy performance of 107% net efficiency and offer superlative ranges of modulation as the systems internal analytical system can modulate the burner modulation range from 54kw to 2.4kw.

The Rinnai HDC 1200i is engineered for minimal energy wastage and maximum energy performance.

It is important to conisder that Part L of the Building Regulations 2013 has set minimum thermal efficiency levels of 90% for natural and 92% for LPG, consequently outlawing non-condensing gas fired water heaters for use in new build projects.

Rinnai is the only manufacturer that can supply a complete range of internal and external ultra-high efficiency condensing continuous flow water heaters, aligned not only to comply but surpass changes on the regulatory horizon.

Rinnai units and systems have become the number one choice for large buildings and businesses, with a heavy demand for constant hot water or where high peaks of demand occur at certain times.

Any number of modules can be manifolded, so the water handling capacity is truly infinite and there is no risk of the ‘cascade’ of hot water ever running out.

The manifolded 1200i units can be delivered direct to site in one complete, easy to manage package and at a very competitive price.

For the end user this guarantees considerable cost savings over other forms of hot water generation. 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 with there being no storage, this scores well with BREEAM.

Available in both internal and external versions, HDC 1200i gives end users 105.5% net efficiency as the condensing process delivers up to 95% thermal efficiency, translating 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.
