Too much
A typical home boiler uses 3000 Watts. 3000 watts is not the correct answer. Watts = volts x amps, or if converting to btu 3000 watts = 10236 btu. At typical household votage of 120, 3000 watts would equal 25 amps and no boiler uses that much current and if your desire is to convert btu to watts I would suspect the average boiler output is far greater than 10K btu. Determine the output in btu/hr of the boiler in question from the MFR`s nameplate and divide by 3.412 3.412btu=1watt/hr. My home boiler uses 3000 watts, it's in my kitchen cupboard and it runs on a 240 v supply.
Hoovers use 1000 - 2000 watts
Not very many, probably less than 20 watts.
As many as the designer likes, but the average table fan uses about 20 watts.
A modem typically uses around 5-10 watts of electricity when in use.
That would depend on the boiler - look on the boiler plate it will tell you the answer for that boiler there.
