Outdated Product
A performant double-circuit gas boiler with a turbocharged combustion chamber and a fan for the forced removal of combustion products. Suitable for heating a private household or an apartment in an apartment building with a total area of up to 192 m². (with a ceiling height of 2.5-3 m). It features a high useful power equal to 24 kW, which allows, in addition to heating, to provide water heating in an amount of up to 11.2 L / min with a difference in water temperatures before and after the boiler from 22 °C. Equipped with an economical modulating atmospheric gas burner and an external combustion air intake system. Equipped with a reliable circulation pump with automatic speed change for quiet and efficient operation. The Viessmann Vitopend 100-W A1JB 24 kW gas boiler has a modern electroni...c control that allows you to control all the most important parameters on a fairly large monochrome LCD screen. It has good efficiency (91%), is equipped with protective systems that are triggered in case of flame extinction, lack of draft or violation of water circulation in any of the circuits. It is carefully adapted for operation in the conditions of east european gas and electric networks: it works at a low inlet pressure of gas and water, it is resistant to power supply voltage fluctuations. Can be mounted directly in living quarters.

And LPG too

The double-circuit hot water boiler Viessmann Vitopend 100-W A1JB 24 kW is an effective combined solution of the Vitopend gas line for simultaneous heating and hot water supply of a private house or multi-room apartment. The model is designed for wall mounting and operation on natural mains or liquefied gas. The forced removal of combustion products from the closed chamber by means of a modulating fan determines a high level of safety and makes it possible to install the boiler in residential areas. The device automatically turns off in the absence of draft, the burner flame is extinguished, low gas pressure and boiler overheating.

Ease of hydraulic maintenance

A comprehensive solution for the interaction and adaptation of all structural elements simplifies the maintenance of the heating device. For example, the AquaBlock hydraulic block, made with Multi-Stecksystem quick couplings, allows easy access to all components, facilitating service and quick replacement of parts. Modern electronic control with a monochrome display equipped with a bright backlight makes all settings and adjustments intuitive and simple. And the integrated self-diagnosis system identifies the causes of malfunctions with high accuracy.

Software weekly timer

The regulation of the heat carrier temperature from 40 to 80 °C makes it possible to connect various types of radiator heating systems to the heating circuit. The high performance of the secondary plate heat exchanger allows you to prepare every minute up to 11.5 liters of running hot water when heated to 30 °C. The manufacturer guarantees stable performance of thermal power at gas pressure ranging from 10 to 25 mbar. And the built-in voltage stabilizer ensures uninterrupted operation of the device during power surges in the range of 170 – 253 V. The optional connection of an outside temperature sensor allows the boiler electronics to autonomously control the device depending on fluctuations in weather conditions. In addition to this, the integrated timer allows you to programmatically set the operation and shutdown of the boiler for the next day or week.
