Saving Energy

... 

with a modern heating system

By purchasing a “modern” heating 
system, you have taken a decisive 
step towards saving energy.
Viessmann boilers operate optimally
to ensure minimum fuel consumption 
for maximum heating value - 
efficient, environmentally friendly 
and comfortable.

Your new heating system provides 
the following alternatives to save 
energy:

a well insulated hot water heating  

     boiler and domestic hot water tank

clean combustion and high energy 

     extraction

...

with proper heating

Additional energy can be saved by 
considering the following measures 
in addition to the above technical 
improvements:

proper ventilation: briefly open 

     the windows 

1

 while turning off 

     thermostats or radiator valves 

2

 

avoid excess space heating; strive 

     for a room temperature of 68º F 
     (20º C) since every 2º F (1º C) of     
     lower room temperature can save 
     up to 5% in heating costs.

proper control settings

.

properly set the temperature for   

     the DHW tank 

4

 

set thermostatic zone valves 

     properly 

2

 

do not block heat transfer 

     surfaces or thermostatic zone 
     valves 

3

control use of warm water: 

     a shower generally requires less 
     water than a bath

close window shutters 

     (if applicable) during night time  
     hours.

with regular servicing

Regular servicing of your heating 
system 

6

 by a qualified heating 

contractor ensures energy-efficient 
and environmentally friendly 
operation.

...

with good insulation

If still searching for additional 
possibilities to save energy, 
review the insulation installed

on the heating system pipes and 

     DHW supply pipes,

on the outside walls and on the 

     roof

WARNING

Ensure properly sized fresh combustion 
air supply to all fuel burning appliances, 
including the hot water heating boiler.
Tightly insulated homes require a duct 
or opening in the boiler room to allow 
outside air in for combustion. Refer to 
codes and instructions.
