Product description
VEDEX 3300 is a wood-fired boiler with induction flue gas
fan. Max. wood length is 0.5 m. The boiler is designed to
be connected to an external water heater for heating do-
mestic hot water.
When firing, the boiler water is partially heated by the
hearth and partly by the flue gas ducts.
Average output during wood burning operation is approx.
35kW (max. output is approx. 40kW).
Hot water heating
An accumulator tank with integrated water heater or coil
is needed for hot water heating.
The hot water capacity is determined by the choice of wa-
ter heater size or the length of coil.

Heating
Hot water is taken from the top of the boiler and routed
to the accumulators. Return water from the accumula-
tor tanks is lead via a charger pack to the bottom of the
boiler. The hot water is led from the accumulators to the
radiator circuit via a shunt valve (SV1), where the desired
temperature to the radiators is maintained by mixing the
hot accumulator water with the cooled return water from
the radiator circuit.
