VIESSMANN Vitotron 100 Wall-Mounted Electric Boiler
Product Information
The Vitotron 100, VLN2 is a wall-mounted electric boiler designed for
residential applications. It offers heating without the use of fossil fuels,
providing a more environmentally friendly option. With a rated output of 4 to
14.4 kW and an actual efficiency of 99.4%, it offers efficient and cost-
effective heating for homes.
The compact profile and integrated control unit make the Vitotron 100
aesthetically pleasing and easy to install. It is perfect for low temperature
heating in space restrictive areas like closets and small mechanical rooms.
The weather-compensated control unit utilizes an outdoor temperature sensor
and heating curves to ensure effective control.
It automatically adjusts the water temperature according to the outside
temperature, resulting in energy savings above typical electric space heating.
The Vitotron 100 comes with a 1.32 Gal (5 L.) diaphragm expansion vessel. It
can power both the internal circulator and an external circulating pump
directly from the boiler. This makes it convenient and versatile to use.
It is low maintenance and ideal for small vacation homes. The Vitotron 100
automatically switches on when the temperature falls below a set minimum
temperature, keeping the room in a comfortable temperature range. It also has
an automatic outdoor temperature sensor and warm weather shutdown feature to
keep remote locations warm without excessive energy consumption.
The Vitotron 100 is designed for easy installation in new and existing
systems. Its space-saving design makes it suitable for well-insulated homes
and can be installed in dual fuel applications such as cold climates where gas
backup is necessary.
It can be used in conjunction with a hot water buffer cylinder for heat
storage, which ensures convenient and inexpensive heating with relatively low
system costs. Additionally, it can be used as a backup to a heat pump or
maintain a storage tank to take advantage of off-peak utility rates.
The Vitotron 100 is also compatible with photovoltaic systems and can act as a
backup to solar thermal systems. This allows for even more cost-effective
operation by prioritizing the use of self-generated energy. The combination of
heat storage and free energy from a photovoltaic system enables very low
running costs.
Product Usage Instructions
- Ensure that the Vitotron 100, VLN2 is properly mounted on the wall.
- Connect the necessary plumbing and electrical connections according to the provided installation instructions.
- Set the desired minimum temperature using the control unit.
- If required, connect an external circulating pump to the boiler.
- For optimal energy efficiency, connect an outdoor temperature sensor to the control unit.
- Adjust the heating curves on the control unit to ensure effective control based on the outside temperature.
- If using the Vitotron 100 as a backup or in dual fuel applications, connect it to the gas backup system or other heating source.
- If utilizing heat storage, connect a hot water buffer cylinder to the boiler.
- If using with a photovoltaic system or solar thermal system, ensure proper connections and prioritize self-generated energy.
- Refer to the user manual for additional instructions on maintenance and troubleshooting.
Aesthetically pleasing and easy to install
The compact profile and integrated control unit of the Vitotron 100, VLN2
electric boiler make it a welcome addition to any space. With efficient
operation and advanced controls, the Vitotron 100 offers superior design,
perfect for low temperature heating in space restrictive areas like closets
and small mechanical rooms.
Without venting and gas connections, this small plug-and-play device can be
installed practically anywhere. Installing the Vitotron 100, VLN2 electric
boiler does not require a gas connection, chimney or boiler room – all that is
needed is a power source.
Efficient and convenient
The weather-compensated control unit utilizes an outdoor temperature sensor,
and heating curves ensure effective control by automatically adjusting the
water temperature according to the outside temperature. The heating curves and
operating efficiencies up to 99.4% ensure energy savings far above typical
electric space heating.
The VLN2 comes with a 1.32 Gal (5 L.) diaphragm expansion vessel. Both the
internal circulator and an external circulating pump can be powered directly
from the boiler.
Low maintenance and perfect for small vacation homes
The Vitotron 100 automatically switches on when the temperature falls below an
individually set minimum temperature, allowing it to keep the room in a
comfortable temperature range. Automatic outdoor temperature sensor and warm
weather shutdown can be used to keep remote locations warm without using
excess energy.
The easiest way to add
hydronic space heating to new and existing systems, with a space saving
design.
The Vitotron 100 is perfect for well-insulated homes and can also be installed
in dual fuel applications such as cold climates where gas backup is necessary.
Heat storage
The use of an electric boiler in conjunction with a hot water buffer cylinder
ensures convenient and inexpensive heating with relatively low system costs.
The VLN2 can be used as a backup to a heat pump or used to maintain a storage
tank to take advantage of off-peak utility rates. The boiler features an
external shutdown input which can be used in conjunction with hybrid systems
and utility Home Energy Management Systems.
The VLN2 is also a perfect partner for photovoltaic systems and as a backup to
solar thermal systems. This allows the boiler to be operated even more cost-
effectively, as priority is given to using the available, self-generated
energy from the roof. The combination of heat storage and free energy from a
photovoltaic system enables very low running costs.
