Eco Hydro Kit is the mini 'boiler room' model designed for integration in Mirai SMI Leaf and Mirai SMI 4.0 heat pump systems.
The Kit is housed inside an attractive metallic grey module with the possibility for exposed installation and is equipped with simplified connections positioned on a special template at the back.
It is the ideal solution for domestic hot water production combined with Mirai SMI Leaf and Mirai SMi 4.0 heat pumps in apartments where users prefer not to opt for a heat pump water heater, insofar as potentially noisy and whose installation would require the walls to be drilled to pass the air ducts outside (particularly if the product needs to be installed in a hallway at the center of the apartment).

It is a genuine "boiler room module" insofar as all the heat pump supply and return pipes, the two underfloor supply and return pipes, the domestic cold water inlet, and the domestic hot water outlet are all directly connected to it.
The water connections are all at the rear with ball valves and identification labels: they are all size 1" F, except for the DCW inlet and DHW outlet connections, which are size 3/4" F.
