After about 12 weeks of research, I came to the following conclusion. It's just my opinion and thoughts so I hope it does not offend anyone:
- The Planar/Autoterms offering is a good quality product at a reasonable price. I just can't give my money to a Russian company fronting as a Latvian. 3 year warranty as standard.
- The Chinese cheap items have a pretty bad reputation. It seems there is a lot of highly inflated/manipulated reviews out there which just don't add up and seem very suspect to me. You get what you pay for and a diesel heater for £200 speaks volumes. No warranties.
- The Webasto and Eberspacher products are very expensive. No denying that but to be honest, this is my first foray into owning a campervan and it seems just about everything is expensive. On the plus side, both these manufacturers offer 3 year warranties. Reviews are very positive with any issues dealt with fairly under warranty.
There are a few other options such as the diesel heater and hob combo which seems a good alternative but a bit complicated for my needs. Given that I am in for around £40K investment of my T6, and that I take my family on holiday in it, I am not keen on the Chinese crap and frankly I am actively avoiding as much of it as I can. (Even though nearly everything is made there these days and my house is full of it!) That leaves me with the Webasto and Eberspacher - time to suck it up and convince myself that it's a sound investment of quality items and a good back-up warranty....
- Pricing: There are plenty of installers around and the pricing for a Webasto or Eberspacher seems to vary between £1200 fitted including VAT to £1500 fitted including VAT. Bodans is about the best at £1200 for the Webasto (not sure if that's including the HD timer/programmer or standard dial) but It's too far out of my way for 2 days to fit. Other places are similar pricing but all too far away for me so I have chosen a local installer with a good reputation who is just 15miles down the road from me. Not the cheapest just shy of £1500 including VAT but more convenient for me.
