Use a tankless water heater. They are a NEVER ENDING source of hot water! They save a lot on water heating costs too!

I've heard that you have to essentially re-plumb your entire house with these tankless heaters. I think for new construction those are the way to go, but to replace an existing old school hot water heater (I've heard) is cost prohibitive. I'll have to look into that though. Good tip!

How do people with huge tanks manage to do water changes without completely draining your house's hot water heater?

I'm not saying my tanks are huge (relatively speaking, these are small tanks), but I now have a 270G, a 240G and a 50G. I was doing water changes in the order that I listed the tanks and halfway through the water change on the 240G, the water coming from the tap started coming out cold. I completely drained the heater and had to wait 45 minutes for the houses heater to do it's thing. To make matters worse, my roommates girlfriend jumped in the shower and had to use ice cold water (I felt pretty bad about that).

So I'm curious how people with real monster sized tanks deal with this? If you turn up the water heater, doesn't that increase how hot the water gets? I don't want scalding hot water coming out of the faucets. That's probably not safe.

Perfect example, take John PTC: How could he do a 25% water change in the House of Sam?

I Was having the same problem...
BEST SOLUTION:
INSTANT WATER HEATER! Now I don't have to worry about my hot water running out...:)
It saves electricity too since its not on all the time. Approx 40% lower than the regular one..

That is true...But, its worth it. At my house we got the entire plumbing changed since the plumbing was about 50 years old...

Not even! They are easy to install and take up 1/10th the space of a regular water heater!
