Low cost of ownership
With minimal maintenance and low operating costs.
ODSHAR ready
Utilizing R32 refrigerant with a global warming potential (GWP) of 675 kg / CO₂ equivalent.
Flexible applications
Use for radiant heating, forced air, chilled panel and domestic hot water applications.
Quiet operation
Maximum sound level at 3 ft distance is between 52 - 56 dB, depending on model.
Installation ready
Each Vitocal 100-AW system comes with installation fittings included.
Vitocal 100-AW: The most accessible air-to-water heat pump solution in North America
The Vitocal 100-AW is a true "all-in-one kit" with an outdoor unit, indoor unit and buffer tank. This provides for a fast and simple installation. The kit can be delivered on a single pallet for easy inventory, delivery, and jobsite ease.
The easiest way to add heat pump hot water
There is no reason to purchase a separate heat pump water heater with the available (optional) indirect-fired domestic storage tanks that save space and installation cost over other types of domestic hot water heating. The optional Vitocell 100-V domestic indirect tanks come in three sizes. They are designed to pair with the Vitocal 100-AW, and the buffer tank can be physically mounted on top of the domestic tank to save space. A customer only needs to decide if they prefer 53, 66, or 79 gallons of domestic hot water storage.
Simple set up and easy control
The indoor unit has an integrated controller that can be run with continuous pumping and outdoor reset using the included sensors (outdoor, indoor, and tank sensors) with no thermostat needed in what Viessmann calls a "European style" system; or set it up North American style with a third party thermostat or with third party zone controller directly wired to the dry contacts on the unit.
Flexible application types
Vitocal 100-AW works in a variety of application types. Whether you want forced air heating and cooling or you are retrofitting a legacy radiant heating system – or a mix of both, these systems easily adapt to different heating and cooling strategies.
