Environmental protection/disposal

Environmental protection is a fundamental corporate strategy of the 
Bosch Group. 
The quality of our products, their economy and environmental safety are 
all of equal importance to us and all environmental protection legislation 
and regulations are strictly observed.
We use the best possible technology and materials for protecting the 
environment taking account of economic considerations.

Packaging

Where packaging is concerned, we participate in country-specific 
recycling processes that ensure optimum recycling. 
All of our packaging materials are environmentally compatible and can be 
recycled.

Used appliances

Used appliances contain valuable materials that can be recycled. 
The various assemblies can be easily dismantled. Synthetic materials are 
marked accordingly. Assemblies can therefore be sorted by composition 
and passed on for recycling or disposal.

Used electrical and electronic appliances

Electrical or electronic devices that are no longer 
serviceable must be collected separately and sent for 
environmentally compatible recycling (in accordance with 
the European Waste Electrical and Electronic Equipment 
Directive).

To dispose of old electrical or electronic devices, you 

should use the return and collection systems put in place in the country 
concerned.

Batteries must not be disposed together with your household waste. 
Used batteries must be disposed of in local collection systems.

Tips on energy saving

Heating economically

The appliance provides a high level of comfort whilst keeping fuel 
consumption and the environment effects as low as possible.

The appliance is controlled in such a way that it delivers heat at the 
correct rate and only if there is a clear demand from the system.

Central heating systems with thermostatic radiator valves

With modern heating systems set around a 20 °C heat loss, the optimum 
setting for a condensing boiler will be approximately 73 °C for the central 
heating temperature. This is to ensure a return temperature of less than 
52 °C.

The system must be balanced correctly and the radiators may need 
upgrading. This allows the boiler to condense as much as possible for the 
central heating system.

The temperature of each room can be set individually (except primary 
room with the room thermostat) using the thermostatic radiator valves.

Room thermostats

Reducing the setting of the room thermostat by 1 °C can reduce fuel 
consumption by up to 10%.

New control systems

Upgrade your heating control system if necessary with the latest 
equipment available.

Roof insulation

Around 30% of the heat loss from a property is through the roof. Replace 
any old insulation with new insulation, preferably of around 200mm 
thickness or more.

Window frames

Single glazed windows, particularly those with steel frames, can lose a 
great deal of heat. Consideration should be given to replacement with 
PVCu or wooden framed double glazed units.

Radiators

If a radiator is sited underneath a window, its performance will be 
affected if the curtains are allowed to drape over the radiator. Shelves 
fitted above or in front of the radiator should also be avoided.

It is advisable to manually adjust all thermostatic radiator valves every 2 
- 3 months to prevent them sticking. Ensure radiator valves are correctly 
set and not damaged.

Draughts

Try to ensure that draughts around doors, windows, letter boxes and 
keyholes etc. are reduced by using a suitable draught excluder.

WARNING: 

Air vents!

▶ Do not block or seal any air vents that are installed to ensure that the 

appliance operates safely.

Curtains

Lined curtains, or heavier full length curtains can provide excellent 
insulation. However, always ensure that the curtains do not drape over 
radiators.
