I put my hot tub on the patio outside the house while the pool got a refurb. Guests seem to like it. Hadn't expected that.
However there are issues:
It is an HSE (in UK) requirement that it is emptied every week or after every guest whichever is the sooner.
This on its own is a significant issue. it takes 1 hour 40 mins to fill up and then 12 hours to get back to temperature. Not ideal for same day changeovers.
There has to be a permanent floating chlorine dosing device, which the guests keep adjusting.
The guests have frequently fiddled with the temp controller, although this is easy to do while trying to turn the blower or jets on. Then they complain
after they leave, that wasn't warm enough!
I had a meter on the hot tub for my own private use, and before all the price hikes it used £80/month, without me emptying it. I suggest this will now be c£200/m.
I have now discovered:
You are supposed to wipe down the splash zone regularly!
You have to keep records of the water tests and what chemicals you have then added.
You have to check it every TWO hours.
You have to have a risk assessment document and a written control scheme.
There is apparently a very real risk of Legionnaires being creates in dirty hot tubs.
You should send off water samples monthly for microbiological testing.
I could go on.
I would welcome any advice!
How does anyone get on with a wood-burning tub? they heat up in 2-3 hours apparently...
Good hosting to you all,
