Outdated Product
Highly economical condensing double-circuit gas boiler of medium power with a turbocharged combustion chamber and a microprocessor control system that supports the connection of external control modules with the eBus bus. The key feature of this model is increased energy efficiency, which is provided through the use of the condensing principle of heat extraction from combustion products. Unlike conventional gas-fired boilers, hot flue gases undergo deeper cooling, allowing the latent heat of water vapor condensation to be extracted and usefully used. This technology allows the Vaillant ecoTEC pure VUW 286/7-2 boiler to demonstrate 5-6% better energy efficiency than conventional double-circuit boilers. The claimed useful power of 24 kW is enough to organize the heating of a house/cottage, a...large city apartment, office, utility or household premises with a total area of up to 192 m2. Thanks to a durable stainless steel plate heat exchanger, the boiler can quickly produce hot water up to 13.5 L/min. This amount of water is enough for the stable operation of one or two points of analysis and to meet the typical household needs of a family of 4-6 people.

The Vaillant ecoTEC pure VUW 286/7-2 heating boiler is in high demand in Europe due to its reliability and efficiency.

Maximizing thermal energy

The dual circuit condensing boiler uses the heat of condensation to achieve an efficiency of over 105%. Modern combustion chamber and burner technology allows modulation of power for optimum heat output.

Efficient hot water supply

The hot water preparation system is capable of providing up to 13.5 liters per minute, serving large household needs. The boiler maintains stable pressure in the heating and hot water supply systems, which guarantees reliability and ease of use.

Advanced control and durability

The integrated microprocessor control system with a simple interface simplifies the operation of the boiler. Connection of external control devices via the eBus communication bus increases the functionality and adaptability of the heating system.
