Does anyone have any recommendations please for a charger that’s suitable for a total of 210Ah.

Did Oliver not offer a solution for you?  They fit charges to your van

I’ve always had a split charge relay but there may come occasions when little travel is involved with long working days.

Yes. I think you will need a battery charger then to top up your batteries most nights. 

You probably just need to keep an eye on the battery state initially to see how you get on.  I have found the heater to be battery hungry.  I have the same batteries as you. I need to fully charge them every night but I don't have split relay to assist the charge.  So you may get away with a charge every 2 or 3 days (not sure).

You'll just have to see how you get on though and find what's needed for you.

oliver said my £40 halfords smart charger would be ok to bench charge overnight if the batteries are low.you only have to put the croc clips on one of the batteries to charge em both up.

I had this one fitted into in my van. Permanently connected to my batteries.  I just connect my mains socket up to my van electric port. ( similar to the caravan ones )

The £50 off the shelf are a waste of time with these diesel heaters you need the B2B GrippaTank split charger with mains hook up trust me I’ve tried numerous ways of keeping these heaters going day in day out and this is the solution. Lots of companies selling these heaters very very few offering the correct method of charging them and keeping them running properly. The above setup works best it’s not cheap though if it’s retro fitted.
