Hi all, I've been reading through threads on similar topics on here and other forums, but still haven't been able to find an answer..
We have a very small new build and are looking to install a Vaillant Aerotherm plus 5kw and a 150L pre-plumbed cylinder, and the max hot water temp will be 50'c.
My understanding of thermostatic showers is that most have a min. temp inflow, which is normally 55'c, and often recommended to be 60-65'c. There is also a temperature differential, often of around 12'c, meaning that whatever the temp inflow is, the max possible outflow of the shower is going to be 12'c lower.
I have a few questions:
Do you have to follow the min temp inflow stated, or could I ignore it and have a 50'c inflow? If not, is anyone aware of showers with minimum temp inflows of 50'c or lower? I'm worried we might not always be at the 50'c mark even..
Are there showers with lower temperature differentials? (ie if it was 7'c, then I could still get 43'c with a 50'c inflow)
Biggest question: The best option is probably just to choose "manual mixer showers" - maybe I'm being really stupid, but I'm finding it incredibly difficult to find any shower sets that aren't either thermostatic or electric.. what am I doing wrong? I can find manual valves by themselves, but no shower sets..
This is the sort of thing I'm looking for.. but with a manual mixer:
