Before setting up the boiler system, consult
the responsible chimney sweep
Standards and guidelines
• VDI 2035, prevention of damage due to corrosion
and scaling in hot-water heating systems with
flow temperatures up to 120°C. Instead of the
maximum hardness of 11.2 dH for 20 to 50
lt/kW specific system volume, the maximum
lime content of the initial fill-up for the boiler
described here is limited to 20,000 lt°dH (system
volume in litres multiplied by the hardness in
degrees of German hardness).
• EN 12828, heating systems in buildings -
planning for hot-water heating systems. The
safety temperature limiter (100°C) is already
installed in the boiler described here. The
contractor must install a sufficiently large
expansion tank (at least 10% of the system
volume), a safety valve and a thermal emergency
cooling valve.
• EN 12831, heating systems in buildings - method
for calculating standard heating load
• EN 13384, flue systems - thermal and fluid-
dynamic calculation methods
• EN 15287-1, flue systems for heating appliances
dependent on ambient air - planning, installation
and commissioning
• Only in Germany, DIN 18160, flue systems -
planning and design
Buffer storage tank is essential
For a wood fire that cannot be indefinitely reduced
in intensity, minimum heating load can be a
problem. A buffer that can store surplus boiler
output is essential.
In Germany, 1. BImSchV (first Federal Emission
Control Act) stipulates a minimum buffer volume
of 55 litres per kW of boiler output. For a 30 kW
boiler, that's 1,650 litres, which is a thoroughly
adequate buffer volume.
The lower the return temperature to the buffer,
the greater its heat storage capacity. The buffer
utilisation of radiators can be improved conside-
rably with very finely adjustable thermostat valves
(Kv less than 0.35).
With a fresh water module, the hot water supply
can be integrated in the buffer to save space, and
solar can also be integrated in the buffer very
simply and effectively.
This device complies with
EN 303-5 Heating boilers for solid fuels
EN 60335-1/A1:96 Safety of electrical appliances
DIN 4702 part 1 and 4 Heating boilers
97/23/EC Pressure equipment directive
2006/42EC Machinery directive
89/106/EEC Regulations for building
products
73/23/EEC Low voltage directive
89/336/EEC EMC direct ive
93/68/EEC Amendment to 72/73
and 89/336
Conformity has been demonstrated. The relevant
documents and the original declaration of confor-
mity (CE) are in the manufacturer's files.
Regulations
• State building regulations
• Industrial and fire safety regulations
• State fire regulations
• In Germany, the EnEG (Energy Saving Act)
with its enacted EnEV ordinances for energy-
saving insulation and energy-saving building
technologies
• In Germany, 1.BImSchV, initial ordinance for
enforcement of the federal pollution control act
for small-scale furnaces.
• In Austria, Article 15 a, agreement on protective
measures regarding small-scale furnaces
• In Austria, Article 15 a, agreement on saving
energy
• In Austria, ÖNORM H 5170, heating systems -
construction and fire safety requirements
