1. General 

 
This user’s guide is meant for the installer and if necessary for the user. It’s a reference to operation 

 

and installation of the WWH heater.  
 

1.1. Description  

 
The WWH is an effective in-direct fired heater.  
The heat exchanger consist of copper tubes and aluminium fins. This is an approved design  for  an 
optimal  heat exchange.   
The grill has been designed to accomplish an optimal air displacement  at the lowest possible  sound 
level.   
With a 5-stage switch is it possible to reduce the air output  and noise level.   
 

1.2. Function 

 
The WWH is in fact a radiator with a fan on the back. When hot water is pumped  through the radiator, 
and the fan is on, the heater will blow hot air. The heater will give no heat  when the fan is off, no 
matter there is hot water running through the radiator.   
The heater requires a control (thermostat) to arrange the supply of  hot water and to switch the fan 
on/off. There are several options for control,  this will be described later in this manual.  
 
For a better air distribution it’s always better to choose  2 or more heaters instead of 1 heater.  For 
example, it’s better to select  two  30kW heaters, instead of  one 60kW heater.  

 

1.3. Matching capacity hot water boiler and WWH   

 
In case the capacity of  the boiler is higher than that of the WWH, the boiler won’t be able to release all 
the heat produced. This will cause the boiler to go on and off (commute). As a consequence of this the 
installation won’t be able to reach the temperature demanded. For small installations it is advisable to 
select a WWH which has an higher output than the boiler itself.

Guarantee 

 

Operation and /or installation of appliances not according to this manual can imply invalidation of guarantee.   

2  Technical features 

2.1 Table with data 

The WWH is available in  8 models with capacities that differ  from 10 to 80 kW. The range of 10-80 kW heaters is 
subdivided in 3 basic sizes. The type number of the appliance starts with the housing model (1,2 and 3). See 
table below for exact measurements.
