Timers for water makers, water heaters, etc.

What timers do you use for AC devices like water heaters? If I run the genset overnight for the aircon I would like the water heater to be on say 6:30 to 7:00am so I can have a hot shower. Watermaker on from midnight to 1:30am etc.

i would like to mount the timers on the electrical panel if possible so the ones that plug into a socket aren't what I'm looking for.

Sailmonkey which one are you suggesting? It needs to be able to start and stop the appliance, not loose its memory if the AC goes out which may exclude digital timers, be able to be panel mounted and look good.

I'm not talking about a seven day timer but just a time I could set for the desired times before I go to bed each night.

How would the timer handle flushing the WC? Seems like you need an integrated control system.

If you are anchored near me with all that crap running at night, I have a Timer you can have for free....

Sorry, link got screwy. This one has a battery backup and can control 2 circuits. I would get a D.C.-D.C. Converter to power the battery backup from house batteries, then set the times you desire everything to turn on/off.

I've been suggesting solutions, but I also feel this sentiment.

Cheechako I don't need a lesson in good manners so put a hold on the sanctimonious sermons.

Yep spending $30 on a timer is evil. Should I rip out my automatic bilge pump switches

What? I'm asking how you'll switch the watermaker to flush. Evil? What are you talking about? Only watermakers I'm aware that can switch to flush by themselves are integrated ones with scheduled controllers.

Ok no worries. I thought you were taking the piss out of me.

It wouldn't flush the WM, just turn it on and off. My understanding is the WM doesn't need to be flushed between every use if it's being used daily or a few times a week.

Re: Timers for water makers, water heaters, etc.

Hi John
You may be over thinking this a bit.

A normal water heater has a thermostat so should shut itself off when it reaches set temp....does yours?

Not good to stop/start R/O (water maker) at full pressure as this is hard on the high pressure pump and possible hydraulicking could damage the HP connections.....

I would just top up tanks after dinner and shut off properly by reducing pressure and allow membranes to "flutter" before shut off.

Enjoy your AC and let the sweaty sanctimonious unwashed campers stew in their own choices...
