Has anyone figured out where to attach a hydronic system to the existing coolant system. I still haven't been able to find a good coolant system schematic.

Garage
I'm looking to fit a Webasto Dual Top evo under the floor in my 130 wheel base diesel van with rear AC. I'm willing to forgo a grey water tank (or have a small one) in order to do it. I don't yet have the vehicle or the heater.

The simplicity of a programable single hot water and hot blown air system is appealing. But it's quite a beast in size.

Dimension:
L 530mm / 21"
W 352mm / 14"
H 256mm / 10"

However it requires some space around it for fittings etc, so total space required is:
L 850mm / 34"
W 392mm / 15"
H 276mm / 11"

Could anyone please comment on whether this would fit and what the clearance might look like on the Transit.

Thank you.

This isn't the best but I plan to get this on page 34: fleet.ford.com/truckbbas/topics/2015/2015_Transit_BEMM_v1-0.pdf and then tapping into this to get my heater in.
Will also be getting this: suremarineservice.com/RL6300B.aspx as the heat exchanger since it's hydronic and mounting either towards the back of the van near the fridge or under the passenger seat.

Thinking of figuring out how to tap in instant hot water... we will probably be using a plate heat exchanger for that. But we're trying to also make sure we don't freeze our lines in the winter so we may have this all routed inside.

I bought my sold 08 Sprinter with the optional Espar hydronic heater in order to use the heater for heating the van with the heated water and for heating the shower water. Been down that road.

Abandoned the idea for several reasons:

1. The Sprinter engine water is hot in winter and summer. Would have required several valves to bypass the water flow so I did not have hot water inside the van during the summer.

2. The shower water would have required hot and cold water mixing to cool the 193 degree engine water down to shower temperature. Also would require plumbing.

3. Before I completed the system, I found a simple cheap method of heating shower water.

I removed all the installed radiant tubing and the 12 volt truck cab heat exchanger from the conversion. If you proceed I have a nice 12 volt water to air heat exchanger I would like to sell you.

What I now do in my climate is heat myself instead of the van. Easy to do with a 12 volt heating pad. Very stealth and quiet and can not leak water. That leaves the problem of getting up in the morning in a cold van. Solved that by selling the diesel Sprinter and buying a gas engine Transit that can be idled. Also bought the remote start option so I can start the engine in the morning to heat van interior before getting out of bed. The shower water is heated in a tank using a RV electrical conversion kit for a RV propane heater. Use a vehicle powered inverter to supply 120 volt power to heat the water. No plumbing or water mixing. All the water in the tank is at the correct temperature as set with the kit thermostat. Pump it out with a 12 volt DC submersible pump to a garden hose and nozzle.

I also liked the idea of using the hot engine water but as I got into it the design became a lot more complicated.
