The EFOY is light-weight and compact – it fits into the smallest of spaces. Ideal installation locations in the motorhome include places like the rear compartment, the side compartment or under the bench. On a boat you can install them in the locker or in the stern, however the EFOY can also be easily stored under the seat or in side compartments of the interior.
Your authorised EFOY dealer will be happy to help you find the right place.

Place your EFOY as close as possible to the on-board battery to avoid a loss of electricity due to long cables. The EFOY needs oxygen to operate – leave some space (approx. 10 cm) around it during installation so that the air can circulate.
Use the supplied accessories to conduct the EFOY’s waste heat away from the device or out of the installation space. The waste heat can be directed into the vehicle’s interior without any concerns, as it does not contain any harmful exhaust fumes. Only the condensation water emitted by the fuel cell should be discharged to the outside.
You may find further information in our installation instructions.
Installation is easiest with the right accessories. Use only genuine EFOY accessories. Take a look at what accessories are included in the scope of delivery.
