Considering getting a hot water system..always gone pure freedom for van mounts etc ..bit pricey their system ..just wondering any alternatives out there from other suppliers..cheers
They are all pricey. If you want a comparison, then ask Ionics for a price. 😅
If you are going down that route then my advice is to go for a 2 operator system. (The reason for a 2 man system is that you can plumb the second system into the tank to bleed of any excess heat to stop the boiler switching off and then restarting. This means that you need a second pump and controller if you only have one.)
I would also only buy a system that uses a 9.1kw boiler and stay away from the cheaper diesel heaters of 5.2kw as they don't provide enough heat imho.
I see some suppliers are using Webasto's inbuilt electronic heat control and calling it summer and winter settings. This means they have done away with the mixer valve which we use to manually adjust the temperature output. It's a pity they are doing this. Ionics started doing this first, but they run their system differently.
My heater is plumbed into the diesel tank. When we use the heater, then the heater uses more diesel a day than the van does as most of our work is within a 10 mile radius of where we live.
I don't know what you're leisure battery is, but if it's a lead acid leisure battery, then most suppliers recommend 2 x110 amp batteries with either a split charge relay or dc to dc charger depending on the model of your van.
Batteries best recharged every night with a smart leisure battery charger.
Do you have an electric reel? If so, all the more reason to have twin batteries.
I also recommend you do a search on the forum on diesel heaters. There are so many posts on here over the years regarding using these heaters.
