<font><font face="verdana,sans-serif">Good questions RT,<br><br>The shed is attached to the cabin, well insulated all around, because I felt it safer to place a propane tankless</font></font> outside the envelope of the living structure. So it was entirely deliberate. The hot water line feeds the shower on situated on the fourth/inside wall of the shed structure. With direct vent electronic ignition tanklesses now available, I probably wouldn't set it up this way now. Built it 13 years ago.<br>
<br>So much of the thoughtful advice on this list is offered as if one were building from scratch. When one is not, the idea of adding on something, however a good idea it might be, does not usually fit into the available space or other site considerations.<br>
<br>Basically I have a well insulated shed attached to the building, with a shower on one side. The bathroom basin is just a bit further on, with the kitchen sink located on the back side of that basin's plumbing. What I would appreciate hearing here, are opinions regarding the efficiency of small tankless for a daily shower where the incoming water is very cold (and not practical to pre-heat unless the plumbing were set up to come ultimately from a passive solar system--but this means glycol, a circulating pump and a holding tank) versus a tradition small hot water heater.<br>
<br>I put in the tankless originally because the cabin would have intermittent use once we built a larger house. Now I'm toying with the idea of replacing that large volume tankless with a small one. The cabin now will have one person living there for several years.<br>
<br>Kathy has offered real life advice that is much appreciated. More thoughts like hers are useful.<br><br>Tankless btw, although they take up less space than a water heater, are not entirely compact unless they are like the Asian and European electric point of use types that usually fit under a sink (and require big time wiring to use).<br>
