ROTEX Domestic Hot Water Heat Pump

Carry out the installation of each air duct making sure 

that: 

 

Its weight does not adversely affect the equipment 
itself; 

 

Maintenance operations can be carried out; 

 

It is adequately protected so as to avoid the 
accidental intrusion of material inside the 
equipment itself; 

 

It doesn’t exceed the maximum suggested length 
of 6 meters (with 2 elbow junctions of 90°). 

 

The maximum total allowable pressure drop for all 
components within the pipe system does not 
exceed 120 Pa, including through holes when 
mounted on an external wall. 

 

When the pipes are installed in a vertical line the 
inlet and the outlet pipe should be at least be at 
200mm distance of each other. 

 

 

During operation, the heat pump tends to 

lower the ambient temperature if the 
external air duct is not enabled. 

 

 

An appropriate protection grid must be 

installed in line with the discharge pipe 
conveying air to the outside, with the goal 
of preventing foreign bodies from 
entering the equipment. In order to 
guarantee maximum device 
performance, the grid must ensure low 
pressure loss. 

 

 

In order to avoid the formation of condensate: 

insulate the air discharge pipes and the 
air duct cover connections with steam-
tight thermal cladding of an adequate 
thickness.

 

 

 

Sound mufflers can be mounted when 

deemed necessary. 

Fit the pipes, the holes in the wall and the 

connections to the heat pump with 
vibration damping systems.

 

 

 

WARNING!

 

 

The simultaneous operation of an open-flue 

firebox (e.g. an open-flue fireplace) 
together with the heat pump causes a 
dangerous environmental pressure drop. 
This may cause the backflow of exhaust 
gas to enter the environment. 

Do not operate the heat pump together with 

an open-flue firebox. 

Use only sealed-chamber fireboxes 

(approved) with a separate duct for 
combustion air. 

Keep the doors to the boiler room closed and 

hermetically sealed if there is no 
combustio air supply between the 
inhabited areas and the boiler room.”

 

6.2.1 Particular installation conditions 

One of the peculiarities of the system is that it can 

cause a considerable lowering of the air 
temperature of the home. 

The exhaust air is colder than the ambient air, as well 

as partially dehumidified. As the air is colder and 
dehumidified, it may be used to cool specific 
environments inside the home by letting it flow 
back inside. 

 

Installation consists of the splitting of the discharge pipe 

to which two shutters are applied (“A” and ”B”). 
Splitting the discharge pipe directs the air flow 
either towards the inside (Fig. 5a) or the outside of 
the home (Fig. 5b).
