If your calcs are right, I say yes--4100btu/h x 5 =20500btu

I use 13500btu/day for hot water. I could use less. 1 shower, couple handwashes, kit.sink use, 1 person. Goes up when the honey is here, not much, it is totally up to her.

I am gone 12-14 hrs/day, and 2 weekends a month. Work, you remember, right? hahaha

I have a 50g elec. heater, 4500w limited to 2, 1 hour events a day. It almost always cuts out before 1/2hr run time. Set for am/pm, I use right after the on cycle, always enough. Over-ride is a pushbutton, you know, when the guests are wasting your hard work.
I am limited to elec(.085kwh) or LPG($3 gal.). LPG at 100% eff. (not possible) would cost more, and the hardware even more yet. Thats stupid.
I am all ears about your project.
