Key Benefits

Energy efficient condensing technology, cylinder loading system, integral solar components and touchscreen operation

The floorstanding Vitodens 242-F gas condensing storage combi boiler is an ideal solution for state of the art heat supply with condensing and solar technology in a detached house. It is recommended for both new builds and modernisation.

A+ through solar integration

Vitodens 242-F is prepared for direct connection of Vitosol solar collectors for DHW heating or central heating backup. The required components and the solar control module are already installed at the factory. Solar coverage is higher than 50 percent. This means that with the installation of only two Vitosol collectors, DHW can be heated with a saving of half the fossil fuel required.

Inox-Radial heat exchanger made from stainless steel

The use of high grade materials provides economical and long-lasting operation. To this end, the Vitodens 242-F is equipped with a stainless steel Inox-Radial heat exchanger which offers the required reliability and ensures permanently high condensing efficiency. This also applies to the stainless steel gauze MatriX cylinder burner.

Last but not least, the gas condensing boiler is both quiet as a whisper and highly efficient. It makes additional use of latent heat in the flue gases and converts 98 percent of energy used to heat. This reduces heating costs and protects the environment.

Environmentally responsible MatriX cylinder burner - Automatic combustion control reduces costs

The integral Lambda Pro Control Plus combustion controller automatically adapts to the properties of different gas types (natural gas, LPG, biogas) and ensures consistently high energy efficiency. Lambda Pro Control Plus helps to keep maintenance costs down.

Vitotronic 200 control unit with colour touchscreen

Both users and contractors benefit equally from the user friendly Vitotronic control unit: The structure of the menu-guided control via the bright 5 inch colour touchscreen is logical and easy to understand. The wizard simplifies commissioning of the boilers after installation.

Consumption indicator in the energy cockpit

The energy cockpit indicates gas and electricity consumption of the heat source directly on the display. It also provides information on solar yield for an energy statement, on the cylinder loading status and temperature curve as well as temperature stratification in the combi cylinder.

High DHW convenience

For particularly high DHW convenience, the gas condensing boiler is equipped with a dual mode enamelled DHW loading cylinder with 170 litres capacity. The water heated to the required temperature is continually charged and therefore immediately available. Sensors ensure uniform temperature heating. In the event of higher DHW demand, the MatriX cylinder burner automatically starts and maintains the required water temperature.

Automatic combustion control reduces costs

All Viessmann gas condensing boilers feature the integral Lambda Pro Control Plus combustion controller. It automatically adapts to the quality of different gas types (natural gas E/L, LPG, biogas) and ensures consistently high energy efficiency. Lambda Pro Control Plus helps to keep maintenance costs down.

Convenient control via app

Controlling the heating centre is particularly convenient via app and the Vitoconnect 100 WLAN adaptor. This establishes the connection to the home router and enables access to the Vitodens 242-F via the internet from a smartphone or tablet computer. The ViCare app controls one heating circuit; for up to three heating circuits.

Extremely easy to maintain

By selecting this boiler, the user will also benefit from low maintenance costs: All components are accessible from the front, no side clearance for servicing is required. When controlling the Vitodens 242-F via ViCare, the contractor can automatically be notified in the event of a fault.
