February 13, 2012

ViessmannViessmann has released severalnew products and technology from an extensive portfolio of high-efficiency fossil fuel and renewable energy solutions.

The new Vitocrossal 200, CM2 gas-fired floor-standing boiler offers advanced Viessmann condensing technology for large residential and commercial installations with inputs up to 1112 MBH. It features an Inox-Crossal stainless steel heat exchanger for maximum heat extraction and reliability and a fully modulating pre-mix cylinder burner for quiet, environmentally friendly operation. The Vitocrossal 200, CM2 offers easy serviceability, fuel flexibility (NP/LPG/LNG) and direct or chimney venting options.

The Pyrot 300 wood-fired boiler utilizes an advanced swirling combustion process, triple-pass heat exchanger and modulating output control to achieve outstanding efficiency of up to 85%. State-of-the-art safety equipment monitors the entire system from fuel feed to venting for safe, reliable and efficient operation in commercial or industrial applications requiring outputs from 512 to 1,843 MBtuh.

The new CombiPLUS Kit adds on-demand domestic hot water (DHW) capability to the Vitodens 100 condensing space heating boiler. Slightly bigger than a large shoe box, the optional CombiPLUS Kit can be mounted underneath or beside the boiler as part of a new installation or as a later addition to a compatible Vitodens 100. Generating up to 3.6 GPM of reliable on-demand DHW, this compact, economical solution eliminates the need for a DHW storage tank in many lower-load applications and is ideal for apartments, condos, cottages, single-family homes or installations where space is at a premium.

Additional new products include the Vitodens 200 gas-fired condensing boiler and Vitocontrol-S in a multi boiler cascade; Vitosol 200-F flat plate and 200-T vacuum tube solar thermal collectors, Solar Divicon pumping stations and system components; and commercial boiler controls.

"Viessmann is committed to developing heating solutions that are efficient, economical and environmentally responsible," says Stephen David, commercial sales manager for Viessmann USA. "At a time of fluctuating energy prices and concerns about climate change, we ensure wholesalers, contractors and engineers have products that meet the evolving needs of their clients."
