Hello!
Basically we have just been granted planning permission for a brand new facility block on our campsite. It includes about 11 showers and 15 basins / sinks.
We plan to use eco shower heads / taps to cut down on water usage
our water pressure is LOW, about 1.5bar.
We are getting another supply for this building, greater than 32mm also, although on the existing block, when too much is on at once the water coming out of the taps and showers just drops so low
We have contacted numerous solar / renewable energy people, every single person has a different idea!
Everytime i search on google, there seems to be a good thread on here! so here i am!
from this forum and google i have gathered unvented cylinders won't work unless the mains pressure is good? although accumulators overcome this?
we have calculated our expected water usage at approximately 1500 litres per hour at maximum times.
we are worried about legionella, although may be only 50 litres an hour at times in the winter
we are worried about the water re heat time!
we have found these tank, http://www.acv-uk.com/slme.htm
possibly get 2 or 3, this also reduces the risk of legionella?
we defintely plan to use solar panels
we also require underfloor heating, but only to stop pipe work from freezing and dry floor
the site can have from 5 people to 600 people on, so another issue is stagnant water?
we have looked into heat pumps but have been told differing opinions, although most say our water volume is too much for a heat pump.
we know we require a back up to the solar, possibly just emersions? although we look like to avoid an oil boiler, although we may have no choice?
how do you calculate what size accumulator you would need if you had a 600 litre tank (3 of them)? and used 3 full tanks per hour? and then what happens if hardly any of that water is used for a few weeks? can it be bypassed at lower times? or can it be stored as its going to be heated over 55 degrees
some people have mentioned heat extractors above the showers too?
even which type of solar panel? evacuated or flat panel? any brands to stay away from?
basically anyyyy advice on anything would be appreciated, but mainly, how to lower the legionella risk / suggestions for a back up to the solar fot hot water / underfloor / stagnant water problem when site has low numbers (shutting down tanks) / low water pressure - accumulators?
i hope some of that makes sense to someone, sorry to have raised so many points in one thread. We have contacted many companies, and it seems only the large ones are interested, but still their ideas are so different! part of our problem is the usage is not constant, it varies so much, although during the summer is our busiest time and also the sunniest time! thanks in advance to anyone! any thing else you want to know or i haven't mentioned, please ask! thanks again, Daniel
