So if there's only one person living in the house and no chance of anyone flushing the loo or turning a tap on would you go for a cheaper one?Because they have a form of thermostatic control to maintain the selected temperature and also to limit the maximum desired temperature.
Thanks for the info, shower is downstairs and comes from mains, electrician ran a new cable in last year was a huge thing but I'll check with him. Spec on the 9.5kw shower says 3.9tlts and 1bar min where the 10kw has 1.5bar minimum. What's the chances of a one floor cottage having less than 1.5bar or should I check it beforehand?Yes, I would go for the T80 but check out a few items first.
Ensure that the shower you are replacing is a mains supplied shower and not supplied from the cold water storage tank (CWST), if supplied from the CWST it will have its own integral pump and should be replaced with a T90 which is also CWST supplied and also has its own integral pump and will be un affected by any mains pressure changes.
If the shower is mains supplied then the T80 is the replacement but IMO requires 2.5 bar minimum static downstairs to provide 1.5 bar dynamic upstairs if the shower if installed here.
Also, a 10.5kw shower will require 10 M2 cable, the existing shower may have 6 M2 and only suitable for a 9/9.5kw shower.
Will check but I'm sure he up rated from the original cable, paid £60 for a roll.Check it beforehand. Sparkys can be tight with cable and generally won't oversize, so it's likely he put the right cable in for the wattage of shower you have now, not a higher one.
