also i dont want to mess about having to  put a heater in my van  during cold nights anymore or having to charge my batteries every night.i can now literally come home from work.purify my water in 40 mins then leave til the morning.

In view of the low mileage you do and now regularly using a diesel heater, I would strongly recommend charging your batteries every night.

Daz, if you only do around 4000 miles a year why is your engine running for an hour a day?

15 mins to work and back and 30 mins for lunch with engine running to keep warm at this time of year. In summer I'll often do the same but with the  air con on instead of the heater.
