Diesel heater.powering

[Trotter]

As discussed elsewhere, I’d like to put the heater under the drivers seat.
If this is possible, and it looks like it will. It would be about 5 mts,from the leisure batteries. But only a metre from the vehicle battery.

Bearing in mind I have a Ctek and Smartpass fitted, could I connect the heater to the vehicle battery without running the battery down to much. That is, relying on the b2b to keep the battery charged. ( Taking sufficient charge from the leisure batteries.
As most of you know on here. Electrikery is one of the dark arts I never mastered.
Diesel heaters are normally powered from the vehicle battery as it’s the only one on the van.

A B2B usually takes power from a starter battery/alternator and puts it in the leisure battery’s Del. Don’t know what you gave to balance out power, best wait gor someone else
Eberspacher are quite often fitted to run from starter battery but usually for short time or when engine running. Start up is biggest pull followed by shutdown. Normal running power demand quite low if left on.
Better to fit to habitation battery but not essential
