System M
Air-to-Water Heat Pump System

Introducing System M
What if you could heat and cool your home with pure, natural water? No need for carbon-emitting gas furnaces or refrigerant lines running through your home. And what if that system could be powered by green energy – residential solar systems or the ever-increasing supply of electricity generated from carbon-free renewable sources like wind, water, and the sun?

Invest in a Greener Future
System M is a radically innovative air-to-water heat pump system that provides comfortable, efficient heating, cooling, and plenty of domestic hot water to your home, without the use of fossil fuels. This complete, packaged system is simple to install, simple to operate, and a simply unique solution for low-carbon heating and cooling.
20% of all U.S. utility-scale electricity is currently being generated from green, renewable energy sources,* with many states and utilities setting a goal of 100% green energy in the next 10-20 years. System M is the perfect solution to take advantage of these green energy trends, as well as energy-efficient equipment rebates and tax credits.

Decrease Your Carbon Footprint
On average, residential gas-fired home heating equipment can produce 4.4 tons of CO2 per year, with a gas furnace producing 3.2 tons and a gas water heater producing 1.2 tons of CO2 annually. System M eliminates the need for these types of home heating equipment – and the carbon emissions they produce. The heat pump used in System M doesn’t use combustion to create heat, so it doesn’t create CO2. System M is also smart grid and solar PV ready, so if it’s powered from a renewable energy source, your HVAC carbon footprint practically disappears.
Increase Your Indoor Comfort
When it comes to comfort, System M uses gentle, lower-temperature water to heat your home, so you avoid the extremely high heat of a gas furnace as well as the dry, uncomfortable air that it produces. System M also enables the addition of even more comfortable heating and cooling options, like radiant floor heating, towel warmers, or integration into a central cooling system.
Naturally Efficient
The ultra-efficient System M is comprised of a sleek, whisper quiet, inverter-driven outdoor heat pump that can be up to 4 times more efficient than a gas furnace. The outdoor heat pump seamlessly integrates with Taco’s exclusive indoor HydroBox to provide a complete system. Heating and cooling is transferred between the outdoor and indoor unit with water, the most natural and efficient energy transfer medium on the planet. System M also produces plenty of hot water, which integrates with an optional indirect hot water tank.
