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.
Compostable packaging
Compostable packaging is used wherever possible in an effort to reduce
the product's impact on the environment and the overall demand for
plastic packaging. Where the following symbol is shown the material is
compostable:
Compostable packaging can be disposed of in a number of ways:
• Home compost heap
• Local Authority garden waste collection
• Local Authority food waste collection, ideally as a food waste bin bag
• Local Authority household waste
Please note that compostable materials cannot 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. "(UK) Waste Electrical and
Electronic Equipment Regulations 2013 (as amended)". 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
Quick Tap function
With the boiler in DHW eco mode it is possible to operate the Quick Tap
function, designed to save water:
▶ Fully open your hot water tap for at least 3 seconds.
▶ Turn hot water tap to fully closed.
1)
▶ Wait up to 30 seconds
as the boiler continues to prepare hot water.
▶ Open your hot water tap; hot water is available
On average, 3.5 litres of water can be saved when using the Quick Tap
function.
Water saving varies depending on user behaviour, pipework design and
the time of year, for example, if Central Heating is on during the winter,
DHW will heat up quicker than in the summer, reducing the potential for
water saving. Savings are calculated based on average mains water
pressure, a heat-up time of 30 seconds and close proximity of the tap to
the boiler.
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.
1) If the hot water reaches the set temperature before 30 seconds has elapsed, the
boiler will stop firing
2) Hot water is available at the boiler. Delivery time to the tap will vary on the
pipework design and tap distance from the boiler
