VIWA 50-65

Viwa 50 and Viwa 65 boilers have gas adaptive system features that provide continuous high efficiency by adjusting the ideal air and gas ratio.

It ensures high productivity every time both in mid-season and at while minimum power is needed with cutting ability its maximum power 1:8 ratio.

Compact dimensions and adjacent installation capability allows installation with less area.

High efficient coil type exchanger provides long product life and decreases clogging risk to minimum with its watertight and wide hydraulic channels.

Central heating capacity up to 390 kW with 6 boilers can be obtained easily with cascade installation.

Thanks to OpenTherm communication protocol it can contact with any cascade control unit sold in the market.

With an external optional module, 4 heating zone or 1 heating zone plus 1 underfloor zone can be controlled.

Illuminated wide information screen shows heater, hot usage water, installation pressure, Outside Sensor connection and room thermostat connection and flame modulation in the screen at the same time.

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

Warmhaus Viwa boilers have room sealed hermetic boiler design and compatible with Ø80/125 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.

High Usage Productivity is ensured by 10 mm thickened insulation which prevents heat loss from boiler body and decreases sound level.
