Hi guys
I'm not sure if this should be in another section as I am asking for replies from experienced and qualified ppls.
The regs show that the water from the PRV/TRV valve off an UVHWH would normally expected to be terminated at ground level with suitable protection.
I have my thoughts about this but has anyone got definitive information as to;
1/ Why it has been done this way
2/ If the regs are not proscriptive then any other no less effective method (ownus on installer to prove that it is no less effective) could be employed, if so what could be done
3/ Given that the temp normally stored in a vessel is at no more than 50-60deg C and it is only in dire emergency (all other fail safes have failed) that temperatures approaching 95deg C would be allowed to pass and that as water at this temp cools down really quickly why can it be discharged somewhere else?
Your thought would be appreciated
Cheers
Russ
