Hi All

I have a question regading cold water systems and electric showers.

I am working through L8 and cant find any mention on this scenario.

Im assessing a small private caravan site which are in use 6 months of the year. A cold water storage plastic tank, held in the roofspace is used which is the correct size for 24 hr use, both tank and pipe are insulated

Are electric showers are a lower risk and I persume the best option to mitigate the risk of contaminated areosols is to set the shower thermostat so there is no less than 50 c after one minute of running, is this correct?

I plan to use this control measure along with weekly temp checks, tank maintenance, site season setup procedures ie cleaning, descaling and use of biocide to sterilise. Along with weekly flushing of showers not in use during the season.

Any help is much appreciated

Thanks

Yes I think you may have gotten some of the facts and figures a little muddled, a shower temperature of 50Deg would present a scalding risk to most people.

May provide a little more clarity with regards to outlet temperature for showers.

Hi

Thanks for the response so far, I can see my mistake!

I understand the system is relativly low risk, I wanted to check my intended controls

Im going to include the following in my control program.

1. maintenance, inspection and cleaning of the tank and pipework

2. Cleaning, descaling and sterlising (although the latter not required by law)

3. Inspection of the quality of the tank isulation to prevent heating in the hotter months

Thanks
