I do not use a generator. I have a 600 watt inverter powered by the Sprinter 12 volt system that provides the 120 volt power. I heat the water in a 5 gallon beer keg while driving until it gets to 90 degrees. A thermostat on the tank turns off the heater. 12 volt pump only sees 90 degree water which is within its specifications. No problem so far with the pump. I get 7 minutes of 90 degree water from the keg. Details in orton DIY post.

I have been pondering the hot water issue for some time, I have a small 5 gal point of use 110v 1200w water heater that I salvaged out of a bathroom remodel.
I am not sure it will work but plan to install it inside the van and use a Honda eu2000 when I need a shower, it should heat enough water to shower in about 30 minutes of run time. That will be about the only time I will need a generator I hope

This should work,

George.

Pretty inefficient to lug a genset and gasoline just for heating water electrically.

We simply heat a tea kettle of water and add it to some ambient temp water to get 90 to 100f shower water. Heat any quantity you want if you use more than our 2 gal shower average. We can typically get a second shower's worth ready on our propane stove in the time it takes for the first person to finish their ablutions. Key to comfort is thermometer and flow rate. Just a few minutes to heat with a pair of 15k btu propane burners. (Can also use our slower inside cooktop for cold weather conditions.)

I also like the compact nature, light weight, portability, and the choice of heating outside to minimize summer heat sources inside the van.

Here's my KISS post.

Dave's immersion heater is a reasonable way to make use of alternator w-hrs. I would consider adding a 12v element if we needed more urban or winter showers.

I am focusing on the weather dependent external work and plumbing and wiring. All of the roof work is practically finished (I still need to mark MB headliner for Maxxair trim) and work below the floor is moving nicely. All tanks are mounted. With the exception of the water pump all plumbing is done. I am thinking to get the Espar D5 this year so all under the floor work would be done this year. See the pictures.

With the recent great weather some progress below the van to report. Today I installed the water pump in the van passenger site b-pillar’s cavity below the floor. This cavity is covered with the black styrofoam mold from the factory. It was a good fit for Shureflo Aqua King Mini 1 gpm pump. If necessary I could increase the size of the pump. The mount with the pump can be easily removed by removing 2 bolts for maintenance. I still need to run the ½” hose from the pump to the water heater and install the strainer.
After finishing the external plumbing, Airtronics D2 installation, and Hydronic D5 all external work will be done. Feels good.

This was my first experience working with HDPE, drilling with regular drill is gorgeous, jig-saw work is easy, but drilling with hole saw is a pain.

For some reason I woke up last night thinking of your posts asking about the best location for your Espar controller. You have probably already installed it but I would put it close to where you sleep since that will be the location where you are most sensitive to the temperature. If in reach from bed you could change the setting without getting out of bed.
I have thought of adding an on/off switch for my optional water Espar so I could turn it on from bed in the morning.

I run into a snafu in getting the fresh water tank 1” fill hose to the engine bay. I thought there was enough space between wheel well plastic cover and sheet metal but I was wrong. I was able to get 3/8” vent and 1/2” shore water supply hoses into the engine bay.

So, my new strategy is to use pressure fill via re-plumbed shore water supply hose which I have already in the engine bay. To eliminate potential damage caused by high pressure inside the tank once water level would reach the 3/8” vent line, my plan is to install the 0.5 PSI pressure relief valve in place of fill inlet on the tank. I am waiting for some prices. Based on my experience the pressure fill could be more convenient than the typical gravity fill, so snafu could end up being beneficial.

Wires routing is almost finished; I still need to decide where to place the remote for the house disconnect relay. Next are finishing designing, making and installing overhead cabinet’s mounts, placing Thinsulate, and replacing factory trim.

From that point all 80/20 furnishing will restart with placing the sofa bed and the galley first.

I've not seen it before.. it looks sharp!
In the real world does it look grey or does it look more tan/cream like this monitor is making it look?

:cheers:

It is more tan than grey but there is enough grey there so awning's silver and Pebble Grey complement.

Overhead cabinets’ installation over the headliner is a little more complex than direct mount to the chassis. For the lower mount I am using a single slot 0.75”x1.5” 80/20 profile and for upper mount simple 5/16”-18 threaded inserts. I am certain that Dave’s way of bolting through the ribs would be stronger but I am willing to take the risk of the weaker mount, I believe still sufficient, for easier location above the headliner. Assuming one 5’ overhead cabinet maximum weight would be 120lbs, 60lbs for upper mounts is 20lbs / 5/16”-18 threaded insert. I should be OK.

George.

Insulation with Thinsulate is done. Key reasons to select Thinsulate were minimum water intake due to about 70% of polyolefins and good noise reduction characteristics, but, there are many ways to do insulation with good results covered well in this forum.

Next steps are making sure I know where exact locations of upper and lower mounts for overhead cabinets are after reinstalled all headliner sections:
- For upper mounts I will transpose location of the upper threaded inserts to the headliner section by drilling corresponding holes in the headliners sections.
- For lower mounts I will mark locations of the lower mount t-nuts secure in place with set screws visible after reinstallation of the headliner.

These steps will allow me to move to the major milestone of the project of reinstallation of the MB trim.

George.
