with potenciometer hack, I made connection in coling and heating water systems, and now cooling water goes trough salong radiaator and in cabin already wormer
Now I dont allow water heated 70*C any more, but only to 30*C, and win -1 I have 18*C temp in cabin.
Best method yet!!! sometimes we need little heating to ocour!
Method 4: Separate (Switch AND/ OR no switch ) 1K-oom Potensiometer aka "resistor trimmer" for Heater.
Pros: 20 to 50 mins, screw driver, soldering required, You can regulate exatly Heater POWER consumption!
