Hello everyone
As a temporary living space (during the house renovation), I am currently building a caravan that stylistically resembles a circus wagon. It includes a small shower and a compact kitchen. (Plans are attached as a PDF)
My original idea to heat the water with an instant water heater turned out to be unfeasible (too high power consumption). So, the only option left is a boiler. It should not be larger than necessary, as space is limited. I am even considering purchasing a horizontal model and installing it below the floor, essentially in the chassis, and surrounding it with an insulated wall.
The question is: How big does it need to be? It must be sufficient for 2 people to shower within one hour (assuming the showering time is kept as short as necessary). Various figures regarding water consumption for showers and the minimum size of a boiler for a small two-person household circulate online. I think it should be at least 100 liters (26 gallons).
Does anyone have experience with this? Any recommendations?
Thanks and best regards
Michael

I’m glad for the advice. Thank you.
How thick should a Wedi panel be when it is glued onto a substructure (three-layer board)? Do I need to waterproof it before tiling? (Shower enclosure)
MichaelI can’t say much about the thickness. In my case, a small knee wall for a shelf in the shower was made from the panels. I believe the panels were about 1cm (0.4 inches) thick for that. The leftover pieces were then used for the side window reveal. The aerated concrete blocks used in the external wall didn’t hold the old plaster well, and it came off when the old tiles that were glued there were removed.
The panels in the shower area were definitely waterproofed with a Botament waterproofing and uncoupling membrane. I don’t exactly remember if a liquid waterproofing membrane was applied underneath as well, but I think the shower area was double waterproofed.

Thank you, that is very helpful. Do you recommend the 2 kW because of the efficiency?

This has nothing to do with efficiency. Standard electrical cables with a cross-section of 1.5 mm² (approximately 16 AWG) can be used continuously under load without heating up or overloading. For this reason, all electrical devices with a 230-volt plug (for sockets) generally have a power rating of only 2000 watts. However, I am not an electrician—someone with that expertise can probably explain this better.
Have fun!
