Hi all -- I've never posted on this forum before but know several of you from kitchens and appliances.
Apologies in advance if I should have been able to glean some or all answers from archives. I looked, didn't see and went for the easy-way: just ask.
I have a Noritz tankless water heater installed over a year now. I've always loved the idea of the thing since long before you could ever even find any for sale here in the States. I don't even care if it never pays itself back; it's just - to me - seemingly so wasteful to keep water stewing forever that this insta-heater seemed to be the obvious only answer for our hot water needs.
However.... I'm not really loving the amount of hot water available. Not in volume, obviously that just keeps coming and coming. But it's not very toasty, what comes out.
So I'm wondering whether there's some error in installation perhaps? It's set as high as it will go, at 125-degrees. I don't know if this is a system-limitation or a jurisdiction one but I don't seem to be able to get the machine to let me input a higher number. It's located literally 5 feet from the shower head as the mosquito-termite might crawl and bore, but probably the pipes have to swoop downward and under the house and back up a bit to the showerhead. Still, it's all on the same, bottom floor, so there just can't be very much tubing in the way. I'm in SoCal so even with zero insulation, shouldn't it stay hotter for the shower?
It's not that it's not hot at all, just not to my taste. I don't know if my hot-shower tastes are untoward; could be...
But I'm wondering whether (a) perhaps there's an installation problem (b) whether there's any way to set the water temperature to higher (c) whether I should try to insulate the pipes, short and relatively unexposed though they be anyway? (d) whether I just have to get used to the cooler water temperature? Is this a compromise people with tankless heaters all accept? Or is there something wrong with my system?
Thanks for any thoughts...
