2.6. RECOMMENDATIONS FOR 

ECONOMICAL USE OF

Your is adjusted at ECO mode for economic use, we 
recommend not to change it

Correct Capacity Selection

Heat loss calculation of the boiler location should be 
made correctly and boiler capacity should be selected 
accordingly. Devices not having adequate capacity shall 
give late responses to heating requests, devices with 
higher capacity may cause discomfort and more fuel 
consumption as they turn ON and OFF more frequently. 
Therefore, boiler capacities should be selected according 
to the place used.

Insulation

Insulation of your building is the most important item 
reducing the heat loss and gas consumption. However, as 
your has the highest thickness insulation of its class, heat 
loss is minimized.

Radiators

Ensure balancing the rest pump head of the appliance 
by making reduction adjustments from radiator 
valves. Placing furnitures in front of radiators prevents 
air circulation and causes discomfort and more fuel 
consumption. Reducing radiator valves of rooms not used 
for a long period or if thermostatic radiator valve is used, 
bringing to the lowest position then, closing room doors 
will provide saving.

Domestic Hot Water

Always adjust the domestic hot water temperature as 
(38~42 °C) for a considerable power saving. In addition, 
high domestic hot water temperatures cause strong 
calcification and that negatively affects operation of the 
device (for instance, longer heating periods, less flow 
rate).

Thermostatic Radiator Valves 

You can both acquire savings and comfort by balancing 
the heat distribution among the house by using 
Thermostatic Radiator Valves.

Room Thermostats 

Your boiler will operate more economically as you will 
have the chance to adjust requested room temperature 
according to comfort via room thermostats. Thus, you can 
adjust temperature of your room as you wish, and also 
you can acquire approximately 6% power saving with 
every degree of temperature decrease.

Ventilation

Do not leave windows slightly open for ventilating room/

rooms. In such case, continuous heat loss will occur and 
not having any certain improvement in the room air.

Fully opening windows for a short period provides a 
better result. Bring thermostatic radiator valves to lowest 
position when ventilating rooms.

Cleaning And Maintenance

Attention:

 to preserve the boiler’s integrity and keep the 

safety features, performance and reliability, you must at 
least execute maintenance operations on a yearly basis 
in compliance with national, regional, or local standards 
in force. 

We recommend a yearly cleaning and maintenance 
contract with an authorised local firm.
