The fan coil used in the Chill Chaser is the LV-70 fan coil. It comes pre-wired to reduce the amount of labor necessary to install it. Its fan assembly has high static pressure, which provides excellent airflow on long duct runs if the Chill Chaser is installed far away from the room it's heating. The LV-70 fan coil is produced with off-the-shelf components, so it's easy to find replacement parts if you need them.
The Chill Chaser's built-in pump can be set to turn on when the solar temperature has reached a specified degree. When the pump turns on, it heats the fan coil, which causes heat to be blown into the room. The built-in pump is housed in the Chill Chaser unit along with the heat exchange storage tank.
The tempering valve is usually placed above the Chill Chaser unit in the pipe that leads to the existing water heater tank. It ensures even water flow throughout the system. The tempering valve is a three-way valve and the "main" is always kept going. The "bypass" part of the valve is on the bottom and is normally open, but it closes upon activation when there is not enough solar heat available to heat the house.
The internal heat exchanger is housed in the main housing of the Chill Chaser. A heat exchanger moves heat from one system to another. The house's existing water heater tank also has an internal heat exchanger, which exchanges water heat for air heat when space heating. The internal heat exchanger can also be used for radiant floor heating.
