For runs under 75ft 4 gauge wire is recommended. For runs over 75ft consult a wire size calculator. Remember that the total circuit length is twice your run. (length of Hot + length of Neutral) Don't divide your run length by 2.
A table in the electrical code book states what size cable or wire is allowed to carry a specific amperage. A #6 copper wire wire with an insulation rating of 75 or 90 degrees C is rated at 65 and 65 amps respectively. A wire is only legally allowed to be loaded to 80% capacity. If the load needs the full 60 amps then the next wire size up must be used. A #4 copper wire with an insulation rating of 75 and 90 degrees C is rated at 85 and 85 amps respectively. De-rating this wire to 80% capacity will allow 85 x .8 = 68 amps.
It depends on the ambient temperature and type of wire but generally the answer is 6 AWG
A common wire size for a 220V, 60A circuit is AWG-6.
#6 wire can take 60 amps up to a distance of 150 ft (240 v system) or 125 ft (120 v system.
The wire size should be increased to #4 for a distance up to 300 ft.
#6 RW90 copper or #4 aluminium. Keep in mind that the conductors can only be loaded contineous to 80%. 60 x .8 = 48 amps.
A #6 copper conductor with an insulation factor of 90 degrees C is rated at 75 amps.
AWG # 6 wire.
AWG # 6 copper.

You need a 60 amp breaker.
The 225 amps is the secondary output amperage. Look on the machines nameplate to find the input amperage. It is that amperage that is needed to size the feed wire and there the breaker size. When you find that amperage you may want to re question the breaker size.
#6 Awg with #10 Ground
If you have 100 amp wire, you can use it for a 60 amp circuit, or for any circuit of 100 amps or less. But if you have a 60 amp circuit, 60 amp wire is thinner and cheaper than 100 amp wire.
A breaker is sized by the conductor that is connected to it but also the load that is connected to the breaker. There are some cases such as motor loads where the breaker has to be 250% of the motors full nameplate amperage.A #6 aluminium conductor with an insulation factor of 90 degrees C is rated for 55 amps.
You need a 60 amp breaker.
A breaker is based on wire size, as the breaker protects the wire and not the load. This is a voltage drop question. A #3 copper conductor will limit the voltage drop to 3% or less when supplying 60 amps for 110 feet on a 110 volt system.
The breaker protects the wiring not the boiler. 12,000 watts at 240 volts will require 50 amps. So, you will need a 60 amp breaker using AWG# 6 wire on a dedicated circuit.
If this is the main service in your home then you probably could not run both appliances at the same time. A range has a 40 amp breaker and a dryer has a 30 amp breaker protecting the feeders to these appliances. Even though both appliances do not draw the maximum current that the breaker allows it would be close. With other devices in use through out the home with the range and dryer on at the same time it will probably trip the panels 60 amp breaker.
If you are using 14AWG wire in your circuit, you will fuse with a 15 amp breaker as 14AWG maximum amperage is 15 amps to 100 ft of wire. If the wire run is longer than 100ft, then you would fuse for 10 amps max. If you are using 12AWG then it can carry 20 amps, etc. Longer than 100ft you would fuse for 15amps. note: 14AWG is called 14/2 and 12Awg is called 12/2 commonly.

60 amp using AWG # 6 copper for branch circuits.
A 50 amp breaker is an overcurent device.

Not that I know of. The largest GFCI breaker I have seen is a 60 amp.
