Rinnai continuous flow hot water heating units have replaced a vastly oversized and close to redundant traditional style of system at the Coombe Hay Care Home in Scarborough.
Coombe Hay is situated in large, attractive and tranquil gardens on the outskirts of Scarborough, only minutes from the town centre and seafront. Coombe Hay offers accommodation which is fully en-suite and suitable for male and female residents with some larger apartments available for two people.
Comgas Heating advised on the replacement system and chose 2 x Rinnai HD55i units – heavy duty high efficiency gas fired continuous flow water heating units with optimal fuel consumption. In like-for-like comparison to more traditional methods, the continuous flow system is proven to be more cost effective over a lifetime. Rinnai is an acknowledged global leader in the manufacture of tankless hot water heating units with group sales approaching £2 Billion.
The Rinnai HD55i is an internal wall hung, gas fired, continuous flow water heater capable of producing hot water in excess of 820 litres per hour at a 50°C rise. The HD55i has a 125mm concentric flue which can be extended up to 15m, less 1m per 45° bend. As with the whole of the Rinnai range the HD55i is ErP A-rated.
The unit is compact, reliable and combines industry standards with innovation and quality. The HD55i operates between 1-10 bar pressure, which is suitable for mains cold water supply and systems with booster pumps and reaches water temperatures of up to 85°C, making the HD55i suitable for secondary return systems.
Rinnai Heavy Duty continuous flow gas fired water heaters feature outputs up to 58kW and water can be delivered at very precise, high volume temperature control. The smart digital controller regulates to within +/- 1ºC without any variation of temperature even with additional outlets. All models have full electronic ignition with no pilot light and operate on demand only, consuming no gas when not in use.
The Rinnai HD55i is a fully modulating 52.6kW unit that can also be installed in a manifold arrangement. This ensures that the system can and will meet any hot water demand at all peak times, no matter what the demand. www.rinnaiuk.com
