The most current means of heating are gas, electricity
and fuel.

You don't have to pay for heat and water as it is included
in the bill. You only have to pay for electricity which

in the summer)
Note that electricity is 110 volts
(220 for certain devices), 60 periods, running monophase,
with plugs of American type in two flat broches.
