Hello guys,
Merry Xmas and happy new year!
After reading almost all the posts in the forum regarding parking and engine heater, i have some things more clear in my mind. Please, let me give you a little of context in case it may help someone else and taking the opportunity to ask some doubts
I have a webasto airtop 2000STC as a parking heater, aftermarket fitted. i have realized i have the engine heater (Webasto Thermo top Evo) in my T6 Nov 2016 and i want to use it to heat water (i have the special water tank for T5/T6 installed underneath the vehicule)
I want to take control of the engine heater so:
1. Webasto engine heater needs to be flashed with oem firmware in order to unlock it. I plant to use VPC, this one in particular (not sure know if it will fit)

As indicated by
@wolny, the firmware is supposed to be this one FL_7E096327
3A__0009.frf - Engine Heater, please, may you confirm?
2. After flashing the unit, connect a Webasto multicontroler to command the unit using this kit:

3. I have had some email exchanged with them and they told me after unlocking the unit engine heater will be able to be managed with the controler. also, they told me cabin air blower will start as well... as i want it to heat water, i dont want to start the cabin blower...
They sent me this manual (attached).
I guess if i dont switch on the blower cabin before parking it wont be enabled after turning on the engine heater....?
Maybe here?
@Robert i would be extremly thankful if you could share some of your expertise here and there...
4. Well.. when i had all of this sorted out, i plan to take the water from the water tank with a 12vpump, take the water throught a heater exchanger like this one:
Material: Cobre, Acabado: Acero Inoxidable, Nº placas: 10, Medidas: 19x7x3cm, Rendimiento: 22 kW, Superficie intercambio: 0,18 litros

Connect the entry and output of the exchanger the water from the tank and take the coolant from the webasto output (warm), take into the exchanger and take it back to the coolant circuit. i would like to modify the coolant circuit as less as i could as all we all know how delicate our vans are....
5. Use a temp controler to activate the 12v pump, when the water tank hits the desired temperature, the pump will stop
