Highlights:
- There are concerns that HWHP systems are susceptible to microbial contamination because they hold water at lower temperatures and in particular regarding Legionella
- This review was approached systematically with 40 papers considered relevant to the topic of Legionella in HWHP, which underwent full article assessment and data extraction.
- The scope of this review established that Legionellaare a known risk in hot water systems that can be carried over to HWHP systems, yet there is minimal evidence to suggest that the current control measures are being appropriately applied to reduce the risk of exposure.
- When considering countrywide legislation and guidance, it appears that the risk is considered lower in single- or multi-family homes that do not require a centralised system.
- The authors found a lack of information regarding the safety of working with HWHP systems with regards to maintenance and replacement.
- This review is among the first to systematically evaluate the risks of Legionellacontamination in HWHP systems.
