Installation of mini electric water heater

[OLIVER DEASY]

How can I install a mini electric water heater so I can have sink hot water and for extended shower hose when hooked up to mains supply.?

about 700 quids

This the unit I would like to use 20cm x 10.5 (small and cost of unit is less than 50 Euro)

I believe these are about 3000W. Not sure that campsite EHU would support that?

Yes, 3000w, so would need a Campsite supply of at least 12amps, more if you are using the vehicle EHU connection as the Charger would be taking some, so at least 14 amps to avoid tripping the Campsite supply.

There are nice camping sites with 16A EHUs. Usually they have also very nice washing facilities and nice hot showers...

Here is the full specification of the mini heater. Here in Ireland we don't have too many serviced campsites with hot water facilities.
Mini body, energy saving, and high efficiency. Safe and intelligent, no water flow stops heating 0.1 second automatic power-off for leakage protection. Insulation, anti-corrosion, anti-deformation. Automatic over-temperature protection. Water flow adjustable. Large-screen digital display. Widely used, bathroom, dormitory, kitchen, hair salon, hotel, etc. Instant heating, really thermostat without waiting. Constant temperature maintains the optimal water temperature for you.

W=AxV so the 3800 W doesn’t add up. Max power would be 2200W

Sounds a great idea although there’s several compounding aspects which are likely to make this very tricky in practice.

I had similar thoughts for Glastonbury type events and ended up getting some dry wash for emergencies, which have yet to use. Have a friend who leads a lot of trekking expeditions and swears by wipes.

Summary of the issues:

• The existing onboard water tank is only 30 litres. A normal shower uses between 10 and 12 litres per minute so that’s 3 minutes or less of water to get wet, wash and rinse off, I’m not sure even with military precision many could pull that off
• Showers are usually mains pressure fed, gravity fed or power. A campsite water supply might well do the trick
• An outdoor shower is going to be bracing at the best of times, and public, and muddy

There are gas heaters available which may work better for a portable shower arrangement.

Best of luck & hope whichever option works for you. Please report back on your progress.
