Hybrid Electrification Benefits

Heat pumps replace less energy-efficient window/sleeve air conditioners to provide baseline heat for most of the winter and cooling in summer. Cozy-enabled radiators will provide supplemental heat when outdoor temperatures drop, energy pricing or demand response events call for it.

How Hybrid Electrification Works

How Hybrid Electrification Works

Step 1: Install Cozy

The Cozy makes efficient use of radiator heat trapped inside of it, creating a thermal battery that it can draw from. This keeps temperatures consistent and prevents a waste of energy, emissions, and money.

Step 2: Install Heat Pump and Thermal Battery

Very simple and quick installation with no invasive construction and a
form factor that residents are familiar with and understand

Step 3: Integrate with Building Controls

Controllable via thermostat which bundles demand response for municipal fuels and electricity.
