Kestrel sees to hot water delivery with Rinnai

Kestrel Mechanical Services of Sevenoaks has completed a refit of hot water heating systems at a care home in the South East of England. Rinnai HDC 1500i on natural gas were installed, including the scale inhibitor system.

The 50-room residence offers high quality accommodation and offers a comprehensive range of care including 24-hour convalescence, respite and palliative care.

Previously, the hot water delivery was provided by a set of satellite domestic boilers placed all over the site. A reliable system was needed to replace the tangle of boiler units.

The Rinnai products mean that water temperature is pre-set through easy-to-use built in digital controls, eliminating the risk of scalding and potentially eradicating the need for thermostatic mixing valves. Water can be used simultaneously at several points of delivery with no loss of heat.

The Rinnai HDC 1500i range is designed for use directly off the mains, with no need for large, ungainly and energy inefficient storage vessels -and is capable of delivering in excess of 780 litres per hour at 65 degrees Celsius, therefore ensuring water temperatures ideal for preventing legionella proliferation. Any possibility of Legionella breeding is minimised as Rinnai units have no storage and can be sited close to the outlet, limiting the environment for bacteria production.
