- Heating with wood – the most natural
fuel in the world
The rising cost of fossil fuels and growing environmental awareness have
to a steady increase in demand for renewable forms of energy. On the
pages, we will provide you with comprehensive information about efficiently
burning wood, a sustainable fuel, in advanced boilers.
A wood boiler is a good alternative to heating with oil or gas. Alongside
environmental considerations, there are also economic reasons for relying on
wood. As an indigenous fuel, wood is very cost efficient and not subject to
extreme price fluctuations.
Thanks to advanced Viessmann technology, heating with wood is now both
efficient and convenient. Whether you are looking for an auxiliary appliance
a complete heating system, the Viessmann range offers flexible solutions,
with logs, wood pellets or woodchips, depending on the type of boiler.
Wood heating systems from 50 to 1250 kW
- Heating with wood – the most natural fuel
in the world
When wood is harvested in sustainable
forestry, it is a renewable and environmentally
compatible source of energy and an important
part of sustainable resource management.
When wood is burned, only as much CO2 is
released as the trees actually absorbed during
the course of their life. That's why heating
with wood is CO2 neutral.
As an indigenous fuel, wood is very cost
efficient and not subject to extreme price
Top technology and reliability
Advanced biomass systems are fully
automated and equipped with control and
safety devices for reliable, efficient and safe
Homegrown and independent
Wood is a homegrown product, is harvested
with a minimum of energy and contributes to
the regional economy
- Heating with airborne and geothermal energy –
making the best possible use of renewables
Heat pumps utilise renewable energy from the ground, sun, groundwater or
They lower consumption of fossil fuels, conserve valuable resources and
CO2 emissions that damage the environment.
Viessmann heat pumps offer their users an additional benefit – many of them
feature active and natural cooling functions. Alongside their classic
heat generators on cold days, they can also create a pleasant interior in
bringing refreshing cool air into the house.
Viessmann's extensive product range offers the right heat pump to suit every
demand. Even at the design stage, structural and geological conditions, as
as personal and individual preferences concerning the heat demand can be
into account. Running a heat pump with power generated on site by a
system is particularly environmentally responsible and very affordable.
Heat pumps up to 2000 kW
- Futureproof and efficient heating technology

In industrialised Western nations, heat generation for residential and
accounts for the largest proportion of energy consumption – and therefore
greatest savings potential. Advanced and energy efficient heating systems
are in use around the world, not only in many private households, but also

Ice store system
- Vitofriocal ice store system – innovative energy
source for ground source heat pumps
The use of an ice store as an energy source
is a particularly innovative solution. The ice
store consists of a tank with built-in heat
exchangers which is buried in the garden and
filled with ordinary tap water. Special solar
air absorbers are installed on the roof of the
house, which draw heat from the ambient air
and insolation and supply it to the tank. The
ice store also draws heat directly from the
- Heating with hybrid appliances –
future safety included
There are many approaches towards energy and heating solutions, and the
decision for one
or the other heating system is not easy. What we do know though, is that the
fossil fuels and electricity are subject to considerable long-term
fluctuations. It is therefore
good when you don’t have to commit to just one single energy source for your

The future-safe energy mix in one
In hybrid appliances, two independent heat generators are integrated into
one unit: a gas
or oil condensing boiler combined with an electrical heat pump. This energy
“renewable” with “highly efficient”, and the user receives the maximum
freedom of being
able to use the least-expensive energy source. Exactly according to the
on the energy market, the control can be set so that when there are
prices, the most cost-effective and efficient operating method is selected.
Power-generating heating system
- Combined heat and power generation
for a high level of independence
When looking at the distribution of energy consumption in Germany it soon
apparent that the heating sector has an important part to play in the energy
Accounting for approximately one third of energy consumption, heating offers
potential to cut back on the use of fossil fuels. As a result, both
decentralised and combined
heat and power generation are now high on the agenda. In future, the
heating system will also come into play when renewables such as wind and
CHP units for heat and power
- An investment in greater efficiency
is an investment in the future
Today, decentralised energy production with combined heat and power
is one of the most economical ways of obtaining electricity and heat while
conserving resources. Its clear advantage over conventional generation is
better utilisation of primary energy. Practically no lost exhaust heat or
losses into the power grids make CHP units a sustainable alternative in
reducing CO2 emissions and conserving valuable fuel resources.
The ecological effect isn't the only positive consequence. Electricity and
costs are significantly reduced and deliver a meaningful economic advantage.
The self-generated electricity is much cheaper than electricity from the

of free solar
energy. By installing photovoltaic modules, users demonstrate their
responsible attitude towards the environment, and make an active
contribution towards protecting the climate by reducing CO2 emissions.
With energy costs constantly rising, a photovoltaic system helps users save
and reduces their dependence on power supply utilities. The power generated
