Hi Guys,
I hear there are some experts on this board so I thought I would see if someone can point me in the right direction with my problem, or at least who I should direct my question to -- a furance expert or a plumber?
I have a Slant Fin Liberty LD-30 furnace with a tankless coil. The unit is 12 years old. The coil was replaced 3 years ago in 2003, it has a 4.5GPM flow rate. The original apparently broke according to the previous homeowner.
The issue is this -- when taking a shower, initially I get hot water for about 45 seconds, but then it jumps to luke warm. It stays luke warm for about 30 seconds, then it gradually kicks back in and can get really really hot! Then after a minute or two it goes luke warm again and gets really cold. It's driving me nuts as you can imagine.
The Aquastat was originally at 160 low, 180 high. I adjusted it down to 145 low, 165 high because I was getting scalded in the shower when the temperature was changing. It didn't help the problem at all, but at least now I'm not getting burned.
I think part of my issue is that my valve in the shower is 40 years old and does not have any temperature control features built in, but this is happening on ALL of my plumbing fixtures (faucets, other showers, etc.)
Any thoughts on what the scoop is with this? Bad mixing valve? Bad coil? I just bought the house, and the lady was good about having a tune up every year. I am the only person living in the house, so I'd like to try and stay away from getting a hot water tank.
Any advice is welcome. I had a 2 year old Weil-McLain furance that was tankless at my previous house and it never gave me any problems at all. I don't sit in the shower for an hour -- I'm in an out in about 5 minutes.
Here are some pictures to give you an idea of my setup. I have a feeling it's a hackjob. If you need bigger pictures let me know and I will be happy to oblige.
Before I call someone, I wanted to get some ideas. Any advice is appreciated!
Thanks for your time,
Chris
