High Efficiency Heat Pumps for Heating and Cooling
The rising costs of fossil fuels and growing concern for the environment are bringing about an energy revolution. And with the continual expansion of renewable energy, heat pumps are becoming one of the fastest growing technologies in the heating market.
Innovative, high performing HVAC solutions for comfort in any climate
Heat pumps are the first choice when it comes to combining cost-effective comfort and environmentally friendly heating and cooling. This is because the energy collected by a heat pump system is provided by the environment in unlimited quantities, free of charge. The system only requires some electricity for the heat pump to make this energy usable. A heat pump works independently of fossil fuels when operated by renewable electricity and actively contributes to reducing CO₂ emissions, helping to protect the environment.
Viessmann offers a comprehensive line of ductless and ducted air-to-air and geothermal heat pump solutions for residential and light commercial applications, as well as residential air-to-water heat pump systems that provide heating, cooling and domestic hot water.
Ductless heat pump solutions
A ductless heat pump, also called a "mini-split", is a type of HVAC system that creates climate-controlled air without the need for traditional ductwork. These systems work by connecting a single outdoor unit to one or more indoor units through flexible refrigerant tubing. So they're simple to install just about anywhere. And because ductless units are placed directly in the room, they offer precise temperature control, better energy efficiency and cost-effective comfort year-round.
A single zone Vitocal 100-S ductless heat pump system delivers heated or cooled air to an individual space – no ductwork needed. The Vitocal 200-S ductless multi-zone system combines one outdoor unit with up to five indoor units to provide comfort for an entire home.
The versatility of ductless systems make them perfect for many applications, including room additions, sunrooms and garages, and they are an ideal air conditioning option for older homes.
Ducted single zone heat pump solutions
Get the best of two technologies in one whole-home system. Viessmann ducted heat pump solutions combine the best of variable-speed inverter technology and traditional ductwork. With a Vitocal 100-S ducted single zone heat pump system, you get the quiet operation, small footprint and enhanced efficiency of inverter technology while allowing you to re-use existing HVAC line sets, ductwork, air handler or furnaces.
With ducted HVAC systems, a central air handler or furnace circulates the conditioned air throughout the home. It uses a strong fan, usually called a blower, to push the air through ductwork that runs under floors, above ceilings or behind walls and out into your living areas.
Viessmann ducted heat pump solutions provide a system that maintains the traditional heating and cooling characteristics of ductwork while leveraging elements of ductless technology. Our systems are compatible with residential fan coils and furnaces, ensuring a seamless integration with your existing HVAC setup for a hassle-free installation that saves you time and money. This solution is an ideal choice when upgrading your home's current HVAC system, constructing a new home or adding on to an existing one.
Reliable Comfort and Energy Efficiency
Geothermal systems, sometimes referred to as geo or ground source heat pumps, offer one of the most advanced and energy-efficient solutions for home heating and cooling. Despite the different names, they all refer to the same proven technology that harnesses the consistent temperature found just below the earth’s surface. By tapping into this renewable energy source, geothermal systems can deliver reliable year-round comfort while dramatically reducing energy consumption.
These systems provide even, steady heating in the winter and cooling in the summer without the temperature swings or noise often associated with traditional HVAC equipment. They also help maintain ideal indoor humidity levels and eliminate the hot and cold spots that can occur in different parts of the home. In addition to improving overall comfort, geothermal systems can lead to significant long-term savings on energy bills, making them a smart investment for homeowners looking for both performance and sustainability.
A ground source heat pump works by extracting heat from the ground and transferring it into your home using pipes filled with a heat transfer fluid. This fluid absorbs warmth from the earth and passes it to a refrigerant, which evaporates into a gas at low temperatures. The gas is then compressed to raise its temperature, making it suitable for heating your home. As it releases heat through a condenser, it cools and turns back into a liquid, ready to repeat the cycle.
Viessmann’s Vitocal 100-WA heat pumps use advanced technology to operate as quietly and efficiently as possible, while maximizing system longevity and ensuring long-term reliability.
Heating vs Cooling Mode
All-in-one hydronic heat pump solutions
The Vitocal 100-AW is a true "all-in-one kit" with an indoor unit, outdoor unit and buffer tank. This residential air-to-water heat pump system is energy efficient and sustainable, and it offers a complete solution for heating, cooling and domestic hot water.
The kit provides for a fast and simple installation, and it can be delivered on a single pallet for easy inventory, delivery and on-site convenience.
Advantages of air-to-water heat pumps
Air-to-water heat pumps absorb and transfer heat to water, so they can also generate domestic hot water for your home. This is an advantage over air-to-air heat pumps, which cannot produce domestic hot water.
If you are already using a hydronic heating system, such as radiant floor heating or cast iron radiators, then an air-to-water heat pump is an ideal solution for your home. Air-to-water heat pumps integrate easily into hydronic systems, and they offer application flexibility so they can even be used with forced air systems (via an air handler).
