Ducted systems offer the option to discretely install a heating and cooling system into premises. These Mitsubishi ducted systems are air source heat pumps and can offer you a way of providing efficient cooling and heating all year round. If you take the ducted model SRR25ZJ-S for instance this is ideal for installation into a bedroom. We have range of systems that go right up to 14kw output. One of the most popular models is the Mitsubishi FDUM71VD ducted system. You could for instance install this in the loft and have the system controlling temperature in three upstairs rooms.
