So here's what I know:
- Started noticing the the temperature of my shower water was fluctuating...generally warm but with patches of cool water.
- Replaced the dip stick (the old one turned out to be fine) and the lower heating coil, which in hindsight was probably OK too.
- Increased the temp by 5-degrees to 130. Water temp still fluctuates, but not as annoying as when cool water was coming in.
Received my electric bill with a huge spike in use. (Huge, as in $400 for two months--crap!)
One more thing,
I noticed that at one end of the house, the hot water tap is always primed with hot water. Even first thing in the AM, after not being used for 6 or 8 hours, it takes no time for the tap to deliver hot water. The hot water tank is on a different floor and the other end of the house, so it would normally take 15 or 20 seconds. The tap on the other end of the house seems to be normal, that is delivering hot water only after discharging several seconds of cold water.
Somehow this has all got to be related, right? Anybody care to speculate what is going on?
Thanks in advance and happy holidays!
