Afternoon all - I wasn't sure which sub-forum, however...

I was wondering whether anyone has used a Webasto ThermoTop or similar in their vans for hot water and heating?

I have one of the "cheap Chinese" blown air heaters in the garage which I have not fitted. I am reconfiguring the van this spring which involves moving the hot water tank (calorifier) to a location where I probably won't be able to connect it to the vehicle's coolant system, so I am considering using a diesel water heater (dozens on eBay, even one on my Freelander...) to heat the hot water and possibly run a vehicle style heater with air blown over a wet matrix (or even a wet radiator), killing two birds with one stone to provide hot water and heating - does this sound feasible? Has anyone done anything similar in an L3 van?

Oh, I'll keep an eye on this as one of my current thoughts is hot water and heating! I was looking at propane/LPG systems however I've seen quite a few install diesel systems that run from their own tank and they are supposed to be great.

Good afternoon all, I am Wolf and I'm writing from Germany, so please excuse me for my bad english.

My proposal is to install such a boiler:

Sorry, there is no english version of this page.

These boilers fits to your chinese heater and you can create heating your vehicle and hot water similar. There is also a version with a second opinion: hot water by 230V. The required power is 500W, so this could also be done by 12V battery or the alternator and an inverter during driving.

One thing more:
there is an chinese air heater with water heating:

Unfortunately air heating and water worming is only simultaneously possible.
Hope, I could help a little bit.
