Anyone with lots of employees will never go down the hot water route it needs to be Installed properly and to do that it’s not cheap per van,I once heard a comment on here from someone similar to that example something like,if I was on my own or had just one employee I would have a hot system-systems it’s just not viable with a lot of vans 🤣 if I built and sold systems they’d only be Hot coming out of my workshop 👍.
