To work "as it should" it needs to be a cooling unit.

Hi,
I tried this things ,to make modified units for heating.In the winter time here its could ,sometime below -30C,but the results its not very good,its expensive to modyfied,use engine heat,that works well.

wouldn,t it be cheaper to use bypass engine coolant over a radiator/ fan ?

Hi,
Only country climate make the diference,below 20C only engine heat works well.Latvia its a nordic country...

The zephyr is designed to cool/null, not heat, it only heats for defrosting.
Monkeypower has the idea, it would work better than trying to convert something else. ;)
