Keeping your water heater running longer without breaking the bank

I get where you’re coming from with the 120°F, but I’ve run into a few situations where that temp just didn’t cut it - especially in older houses with long pipe runs. Had a call last winter where folks kept getting lukewarm showers, even though the heater was set right at 120. Ended up bumping it to 125 and suddenly everyone was happy. Guess it depends on the setup and how far the water’s gotta travel... sometimes those extra few degrees make all the difference, even if it’s not textbook.

Funny, I just moved into a place built in the 60s and thought 120°F would be plenty. Turns out, my morning showers were more “refreshing” than relaxing... Bumped it up to 125 too and now it’s actually hot by the time it gets upstairs. Guess I’m learning that what works on paper doesn’t always work in real life. Still kinda nervous about energy bills creeping up though - does 5 degrees really make a big difference?

Totally get where you’re coming from - when I moved into my current place, I thought 120°F was the “eco-friendly sweet spot” and figured I’d be saving tons on my bill. But yeah, it was more like a lukewarm wake-up call than a shower. I bumped mine up to 125 too, and it actually feels comfortable now.

As for the energy cost, I’ve read that every 10 degrees you raise your water heater can bump up energy use by about 3-5%, so 5 degrees is probably only 1-2% more. Not nothing, but not huge either. For me, it’s worth the tradeoff for a decent shower, especially in an older house with long pipe runs.

I will say, insulating those pipes and the heater itself made more of a difference than fussing over the temp setting. Might be something to try if you’re worried about creeping bills.

Yeah, I tried sticking with 120 for a while and honestly, it just wasn’t cutting it - especially in the winter. I get the eco angle, but if you’re shivering in the shower, what’s the point? Insulating the pipes helped a bit, but not as much as I’d hoped. Maybe my house just leaks heat like a sieve. At this point, I’m not convinced those few degrees make or break the bill anyway.

Honestly, you’re probably right. Bumping it up to 125 isn’t going to blow up your energy costs unless you’ve got a massive household or something. I’ve seen way more people regret freezing showers than a slightly higher bill. Insulating pipes does help, but if your house is drafty, heat loss is just gonna happen. Sometimes comfort wins out - nothing wrong with that.
