Clifton Park Hospital in York, advised by A J Gastech, has chosen Rinnai to upgrade its hot water heating system to meet the increasing demand whilst staying economically and environmentally efficient. This upgrade is crucial for legionella prevention, ensuring that the hospital's water systems are safe and compliant with health standards.
Clifton Park Hospital, which opened in 2006, boasts first-class medical facilities including 24 beds, two theatres, a day case unit, a large outpatient department with X-ray facilities, and on-site physiotherapy, including a small gym area. In 2018, the hospital expanded with a new outpatient department featuring 11 consulting rooms, two treatment rooms, and additional X-ray facilities.
The hospital prides itself on offering exceptional care and service to all its patients, currently holding a 5-star rating on NHS Choices, a 4-star rating on Google, and a 4.7 rating on Facebook reviews. In the most recent NHS Family & Friends Test survey, 100% of inpatients and 98% of outpatients recommended the hospital.
The new water heating system features three Rinnai HDC 1200i units plus a 500-litre cylinder. The previous Rinnai HD50i served the hospital's hot water needs for 10 years without issue, but due to the hospital's expansion, a new bespoke system was required. This upgrade not only meets the increased demand but also enhances legionella prevention by maintaining optimal water temperatures.
The decision to upgrade to more energy-efficient condensing hot water heaters and incorporate the 500-litre storage vessel allows the hospital to handle peak hour demands effectively. The heating engineer contractors, A J Gastech, were given just a 14-hour window to remove the existing system and install the new one, a task they completed with time to spare, showcasing their expertise and professionalism.
The Rinnai HDC 1200i continuous model is designed for high-demand sites, capable of delivering 2000 litres per hour. It guarantees unparalleled levels of efficiency and hot water delivery, ensuring compliance with future regulations. This precision-engineered unit can be combined with multiple units into a single, easy-to-handle module, making it ideal for NHS water systems and hospital heating systems.
Both internal and external models of the HDC 1200i achieve a market-leading energy performance of 107% net efficiency. The system's internal analytical capabilities allow modulation of the burner range from 54kW to 2.4kW, ensuring minimal energy wastage and maximum performance. This is particularly beneficial for hospital heating systems, where consistent and reliable hot water supply is critical.
The manifolded 1200i units can be delivered directly to the site in one complete, easy-to-manage package at a competitive price, offering significant cost savings over other hot water generation methods. The compact footprint of Rinnai units optimises plant room space and ensures accessibility for maintenance and servicing.

On-demand water heaters like the Rinnai HDC 1200i units have significant potential in new builds and refurbishments, especially in replacing old systems and gravity-fed water systems that use stored hot water. The Rinnai Infinity HDC 1200i also features lower greenhouse emissions due to its reduced NOx burner technology, aligning with environmental goals.
As Clifton Park Hospital has a secondary flow and return system, complete range modulation ensures the system operates at optimum performance at all times, further enhancing legionella prevention and the overall efficiency of the NHS water and hospital heating system.
