Will one 3A feed supply two of these?

Pretty well any mains device has its power consumption given somewhere -
usually on the device itself. Usually in watts or VA. For this purpose
they can be considered the same. Add all the 'watts' together and divide
by mains voltage - use 250 to make the maths easier. That gives you the
figure in amps. The A N Other *might* be a problem - if it is a 3 kW fan
heater.
