Environmental protection and 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.

Old electrical and electronic appliances

This symbol means that the product must not be disposed 
of with other waste, and instead must be taken to the waste 
collection points for treatment, collection, recycling and 
disposal.

The symbol is valid in countries where waste electrical and 

electronic equipment regulations apply, e.g. "European Directive 2012/
19/EC on old electronic and electrical appliances". These regulations 
define the framework for the return and recycling of old electronic 
appliances that apply in each country. 

As electronic devices may contain hazardous substances, it needs to be 
recycled responsibly in order to minimize any potential harm to the 
environment and human health. Furthermore, recycling of electronic 
scrap helps preserve natural resources. 

For additional information on the environmentally compatible disposal 
of old electrical and electronic appliances, please contact the relevant 
local authorities, your household waste disposal service or the retailer 
where you purchased the product.

Batteries

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 65 °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.
