The Solar-Ready Vitodens 343

For modern heating with condensing and solar technology in detached houses, the Vitodens 343 is an energy-efficient, environmentally responsible and advanced solution.

The Compact Condensing Tower Vitodens 343 offers energy-saving condensing technology, powerful DHW heating through a cylinder primary system, and is solar-ready - all inside a casing with a footprint of only 677 x 600 mm.

At the core of the Vitodens 343 lies the new Vitodens 300 wall mounted gas fired condensing boiler (13 kW) with the intelligent Lambda Pro Control combustion control unit. The integrated DHW cylinder with 250 litres capacity is suitable for incorporating a solar heating system. It makes its case through a high solar coverage rate based on its large cylinder capacity and the automatic heating suppression. The 16 kW booster function of this condensing boiler ensures high levels of economy and excellent DHW convenience.

Vitodens 343 is fully prepared for solar operation, either immediately or in the future. Solar-Divicon and the Vitosolic 100 solar control unit are integrated and ready for use. All functions are matched to one another and have been factory tested.
