Can we please revisit this? With low hot water usage, the thought was to get a standard electric tank because stand-by loss is best. But I'm hearing the following.
I'm getting a new gas boiler. It will be cold start. I have low water usage. In summer, I read the boiler only fires up 1 or 2 times a day to heat an indirect tank. If you are gone all day (use no hot water) it might not fire at all. If firing, that is maybe 20 minutes of firing. This gives the efficiency of gas as a fuel, but also that indirects are very well insulated and are as good as electric tanks for stand-by loss. Indirects also have quick recovery.
I'm beginning to think the indirect may be better (a bit more expensive at install) but less maintenance as no anode rod and all that standard tank parts and maintenance like heating elements, needing flushing, etc.
