11 Reasons to Choose Viwa Boiler

Viwa90-115-125-150 kW

Perfect Body Insulation High usage efficiency is ensured thanks to 10 mm thick insulation which prevents heat loss from boiler body and decreases sound level.

Built-in Cascade Control UnitBuilt-in Cascade Module control unit provides connection and communication between boilers without needing additional devices. So each boiler can be used as master or slave.

Perfect Heat Transfer Aconit® BurnerThe Aconit® burner with excellent heat transfer is specially designed for maximum utilization of the heat exchanger surface. Thanks to its wide modulation rate and low surface temperature it provides highest performance and lowest NOx emission.

Easy and Quick installation with Smart Plug System Easy and quick cascade installation up to eight boilers with to built-in cascade unit and smart plug system.

Built-in Air & Dirt SeparatorBuilt-in mini Air & Dirt Separator and additional air separator on the exhaust manifold prevent air and particle in the system from damaging the exchanger.

Compatibility with different cascade control panelsWarmhaus Viwa boilers are able to communicate with OpenTherm communication protocol and work with various cascade control systems available in the market.

Cascade Installation up to 14 x 150 = 2100 kWIt is also possible to build cascade system without cascade control unit up to 14 boilers and 2100 kW.

Al-Si-Mg Alloyed Monobloc ExchangerAl-Si-Mg alloyed exchanger is more efficient compared to stainless steel and highly resistant to corrosion.

Multiple Part ManagementWith an optional MLC 30 module 4 direct heating circuit and hot water tank or 1 low temperature zone, one high temperature zone and one tank circuit can be controlled.

Installation to Limited Space With Compact Dimensions W:615 x D:490 x H:720 mm

Compact dimensions and adjacent installation capability allows installation with limited spaces.

Hermetic Flue Connection Warmhaus Viwa boilers have room sealed hermetic boiler design and compatible with Ø100/150 mm concentric flue connection. Each boiler can be used with its own flue sets independent from each other which makes cascade systems easy to install in roof spaces without a stainless steel flue.
