superstor questions

[MrEd]

A question about superstors - specifically looking at the ssu-60 or ssu-80.

Any information (or even best guess), about how much hot water you could get off of one of these, if the tank was at temperature, and you didn't add more heat while you used hot water?

Specs say both of these will lose just about 1/2 degree per hour, but that assumes you are not introducing cold water at the bottom and taking the hot off of the top. What I am trying to figure out, for this upcoming first year with my tarm, if I don't have storage hooked up, could I bring the superstor up to temperature and get my domestic hot water all day without the need of firing it more than once in a day?

I have an older 40 gallon superstor. It's good for about three showers if you don't have preheat or storage or superheating. Of course, that's normal showers, not teenage girl showers ;-)

I ran without storage the first year. It was workable but not ideal. Basically, we'd have the kids shower in the evening when the boiler was going. The tank would then carry us to the next fire. Often, though, the risk of running out of hot water made us build a fire when we might not have otherwise.

I'd think the 60 or 80 would do fine unless you're infested with teenagers.
