My water heating system took a turn the other day when I posted the above pics. Everything working out now.
When we moved into the condo it had the rainfall shower heads I've never used before. It was ok but the lack of pressure I was used to kinda sucked.
I always meant to check if there were water flow restricters in the shower head, but someone from the condo had told me they checked and ...
dammit my lazy ass went no further until a couple days ago when I took the head down and pulled out a bunch of restricting crap. Took all that **** out and now we have a real waterfall shower.
So water is flowing like Niagara and more than hot. Still, I check the hot water heater that is set at 48 C. (118 freedoms) Too hot when only hot water, but I want to check how things are going for the hot water heater.
oh oh an error code I figure it's too much flow for the heater to keep up now, even only running one shower. It seems to work fine but I don't like the error code. I start to back it off to 47 C; it starts flashing E5 and the temp... that's better. 46 C only saw the error code pop once in 5 mins.
I've got it set at 45 C (113 freedom) and no errors.
This is the cold time of the year so the water coming in is about as cold as it gets, but the unit is handling it fine now backing down a bit, and the water is plenty hot for us still.
