I'll reconsider proactive replacement. The estimate is probably ballpark - apparently I can't just remove and replace; there are code changes that need to implement (venting system or whatever).
House is on a slab. I think all the lines are in the slab. Oh, I do have a recirculating line. Is that perhaps contributing to the swings? Causing constant mini-short cycles during winter?
I tweaked the dial last night. This morning, first use was perfect at about 122. I'll measure periodically today to see what the high point might be; adjust down a little if it gets much higher than 122. Tricky part is keep low point above 115.
I think your "too low" temp and "too high" temp are fairly close together and may not be doable by an old heater. New digital - maybe. tankless - almost positively doable. I kindof think with the old tank you have, you're just going to have to live with either an occassional coldish bit of water or a scalding every now and then. choose one. :-)

konata88Yea, that's probably the case. I'm now trying to keep the high < 125F and plan to live with whatever the low is. I'm thinking this is more exaggerated in winter than during the summer (and likely cooler water is more tolerable during hot summers).
