In place of utilizing gas like oil or all-natural gasoline to generate warmth, ducted and ductless warmth pumps extract heat from the surface air and transfer it indoors to provide warmth.
Directional diffusers supply great airflow distribution. Every of them materials about 300 cfm of airflow at small noise, hardly audible. They are mainly coupled using a radial damper, a crown damper or an opposed-blade damper for airflow Command.
