I added up the max wattage of your stuff (guessing on the 24 switch and USG4P) and got a high value of 1000w (generous max). I would get something like these:
•This has a 7mIn runtime at 1000w, but you most likely won’t use the max wattage.

Look more at the watts and runtime then volts. You can get rack mount versions but they will be higher cost.
Of course it can, mine is natural gas, but not as easy for an electric one. I have a UPS hooked to mine, so I can have hot water during power outages. Mine is a standard PC UPS form APC, with a supplemental extra battery pack hooked into it for a combines 3000VA of power. Mine is US, so 120volt, and is a Rinnai RUC98i, which can heat 9.8 Gal/min. You only need power to run the igniter, and then the brain to allow it to measure and mix the heated water with fresh water in order to bring it to the temperature the unit is set to.
When the unit is on (and mixing hot with cold water) it draws more than when idle. If I leave it on 24/7 it has juice for about 2-3 days of powering just the tankless. If I unplug it when not about to use it, easily a week of power.

I bought the APC equivalent because it has an expansion slot for more battery capacity. (it's an additional unit)
I picked up the UPS+Battery for ~$220 off Amazon used.
I've had my eye on this, its tempting. This is also the only UPS in the series that can use the external battery pack for a big boost in run time.
Found this for you: http://www.apc.com/products/runtime_for_extendedruntime.cfm?upsfamily=27 on the manufacturer's website.
This page says that the BR1500G (the one you linked) will last a little over 2 hours at 50W. You might get a little longer than that at only 30W, but UPSs are less efficient at lower loading.
Apparently you can also pair that unit with an external battery and get nearly 7 hours, though now you've spent nearly 300$ on batteries.
I hope that helps!
Remember when power goes out it doesn't mean you have zero hot water, you have simply lost the ability to produce more hot water. You still have 40gal of hot water in your tank.
The thing is, UPS system's aren't really designed for backup power unless you add a crapload of additional battery capacity. They're designed to keep running for just long enough for you to either gracefully shutdown and power off your equipment, or hookup a longer-term power source such as a generator.
I have this 1500VA model from APCC along with this extended runtime battery hooked up to my home PC. Dual 24" monitors plus a mid-range older desktop. Power goes out, I have maybe an hour of battery. Without the add-on battery pack, it lasts fifteen minutes.
I have a smaller 1200VA UPS for my wireless router and DSL modem, last time the power went out I think the timer on it said somewhere around 300 minutes of runtime remaining. That's with hardly anything plugged into it - if I had a PC hooked up, it would probably be 30 minutes or less.
You're really better off just getting a generator.
If you dont need rack mounted, Ive found my APC Back-UPS Pro 1500VA UPS with the extended Battery to be very good. Current load is 130w and runtime is 178 mins.
If I turn on the desktop that is also on there, runtime drops to just over an hour with the combined ~250w load.
I have it connected to my FreeNAS whitebox via the included USB, with NUT running on FreeNAS that shuts down the rest of the applicable servers via network.
Total cost new: ~$310 USD.
Edit: N.U.T.
Get a 1000VA/600W unit like this one.
Edit: if you need it to be powered on for an hour, get the 1500VA unit + Quad-battery expansion.
OK, maybe only for 2 laptops - https://www.amazon.com/APC-External-Battery-BR1500G-BR24BPG/dp/B0047E5B90
They say that 50 Wt ~= 7 hours
Or it's bad idea?
Get one, never look back. I had a power outage take out 2 of my monitors. Should have bought one of these a long time ago. You can even configure it (via a USB connection and some software) to auto shut down the PC for longer power outages so it doesn't drain the battery.
If you really need longer power duration throw one of these in there as well.
EDIT: Do some research because there can be issues with compatibility depending on if the device needs pure sine waveform or can used stepped approximation.
