Should be cheap as not much power required to control the gas fired unit. Go
to any office or computer store and get one suitable for you unit - should
be under $100. You need to replace the UPS battery once every few years.

ahh check the current use of the tankless, if it uses a fan for exhaust
you may need a really large UPS.

did you knpow there are commercial size regular hot water tanks, they
can supply a hotel continiously so one home would be easy.. kinda
pricey but available

My Takagi draws less than an amp maximum, and that's briefly while the
blower is clearing the exhaust after the burner shuts off; most of the
time it's much lower draw. Any decent UPS can handle 120W loads.

You know, I really don't think it's worth it to get a UPS just to insure
I have hot water if my power goes out. I'll be a lot more concerned
about the power and especially the food in my refrigerator going bad.
Hot water? Holy smokes, my ancestors had to build a fire to get it. I'm
not going to be such a pussy about it.

Frozen casseroles from the deep freeze will keep the fridge cold enough
that milk lasts for many days. Think of it as an icebox with edible
ice. Some of the frozen stuff is going to thaw anyway, might as well
put it to use.

While the house was jacked up getting a new foundation, we spent 6 weeks
with the gas disconnected. Boiling water on the stove for baths gets
old fast when you have twin toddlers.
