Using 200mm fan and temperature control from China, to improve the airflow on my radiators.
When using a heat pump, It's economical good to run it with as a flow temperatur as possible. For example. 113 º F, it makes the heat pump is very efficient. But it puts great demands on radiators.
It usually works by hot air rises, and in this way the air in the rooms where the radiators, is rotated and warm up. But when the radiator is not that hot, it circulate very slowly.
And that is what I am trying to enhance by installing a blower.
