2 System Requirements
Appliances from wodtke are always connected in some way to other domestic installations or
products and therefore, like all technical products, they have certain system requirements that
must be met to ensure trouble-free operation. The following sections specify some of most
important requirements, which is to say that they do not necessarily name all requirements.
Please observe all instructions and information, as already stated in the introduction. It is always
advisable to have the installation of a pellet stove planned thoroughly in advance by a qualified
company to ensure that the system components work properly together and the intended overall
solution is achieved. wodtke provides a wide range of compatible accessories for this purpose.
2.1 Application scope and limits
Airplus appliances:
•
Single-room heater (warm air heater serving the room of installation or several rooms)
o
Capacity range 2-6 kW: maximum energy output = 9,000 kWh per year at 1500 full load
operating hours at 6 kW.
o
Capacity range 2-8 kW: maximum energy output = 12,000 kWh per year at 1500 full load
operating hours at 8 kW.
Waterplus appliances (capacity range 2- 10 kW):
•
Auxiliary heater in addition to existing ones (auxiliary room heating and domestic water
heating)
•
Single-storey heater without domestic water heating (domestic water heated separately)
•
Whole-house heater in combination with other heat generators
Waterplus appliances should always be planned with particular care, since they not only
produce heating water but through heat irradiation and convection also heat up the room of
installation itself. Please observe the following in this regard.
A Waterplus pellet stove alone is not sufficient as a hot drinking water supply because it
would also heat up the room of installation when used for heating drinking water in the summer.
For this purpose a combination with solar thermal energy or other heat generators (for ex.
electric, oil, gas) is required and, in fact, the ideal solution.
Before opting for a specific model it is always necessary to determine on the basis of the
standard calculation rules the heat demand and from this the heating capacity required for the
room / flat / house in question. Confer DIN EN 12831 (design heat load of buildings) on this
point.
When a pellet stove is to be used for whole-house heating the energy demand for heating
drinking and domestic water must be considered in addition to the pure room heating
demand. Another point to bear in mind is that heating a new building can require more than
20% additional energy during the drying phase (approx. 0.5 to 1year) in some cases.
If the temperature is to be set low at night and there is a high demand for hot domestic water
(shower water) in the morning, it must be ensured that the stove has sufficient heating
capacity to meet peak demand. This can be achieved, for ex., by means of a sufficiently
dimensioned buffer storage in combination with other heat generators (electric immersion
heater, oil or gas boiler for reserve capacity).
Please also note that the heating demand of a house is influenced to a large degree by its
occupants’ heating habits and can thus turn out higher than calculated (for ex. due to high room
temperatures, frequent airing, tilted windows etc.).
