Rinnai: Hot water temperature precision is ‘paramount’

Rinnai: Hot water temperature precision is ‘paramount’

September 4th, 2020

Rinnai says hot water temperature precision and control are major factors in the design, specification, and installation of any hot water delivery system – with the increased risk of Legionella in systems following the lockdown.

Reports have also emerged from certain industries – such as laundry for healthcare and care homes – that the temperature of the hot water is critical to the cleaning and disinfecting process to render the possibility of transmitting the coronavirus as near to zero as possible.

Chris Goggin, Rinnai Operations Director, said: “At a time when the need for clean and sterile indoor environments is paramount, we must re-consider the design of the provision of hot water services which incorporate heat engines to provide large volumes of hot water and provide hot water at the precise temperature needed.”

The benefits of temperature control are not new – in the world of building services, for example, it is well understood for anti-Legionella regimes. 

All hot water delivery systems in any commercial or institutional sites should have certain measures and procedures carried out in case of potential Legionella spread during the lockdown. These must be made before the system is made live.

ACOP L8 guidelines, produced and published by the Health & Safety Executive, list the details and necessary procedures to ensure system cleanliness. According to ACOP L8, continuous flow direct to outlet systems are low risk for Legionella, due to it allowing for a full turnover of water volume, no stored water and accurate temperature control.

Chris Goggin says: “The necessity to design hot water systems at a set point greater than needed to satisfy Legionella concerns, or temperature loss fears, or to build in shunt pumps to continually pump water round an unoccupied building to prevent stratification, raises the real question that any user, designer, consultant or manufacturer must ask: ‘Are we using the right system for the right job?’
