Hot water and boondocking

[rogerwwebb@...]

I have a system such as you describe in my home. A small pump and timer
(110 volt) in the water hot water line circulates the hot water throughout the
house, so hot water is available at each faucet when it is turned on. The
timer can be set like a light timer, so it does not circulate at night.

We took a 4 day trip and had only power available. I left with a
full water tank and mostly empty grey and black tanks. By the last
day I had about 1/4 tank of water left. I began to think about ways
to conserve water to streach the time we could stay. One thought was
the waste of water waiting for the sink or shower hot water to come
up to temperature. It was cold outside so it took a while, wasted
water and holding tank capacity.

In hotels/motels/large buildings they use a circulating system
that keeps the hot water supply hot so you don't wait for hot water
at the tub or tap. It would seem that this could be done in an RV by
adding a return line from the far end of the hot water system, a one-
way valve and a pump. Then all you would need to do is activate the
pump for a minute or so to charge the system, and then start the
shower. It would conserve the water supply as well as the grey tank
space.

Has anyone seen this kind of system in use?

Gardner,
I'm all ears for this. Had the same thought while out camping this past
weekend. Thanks for posting.

One easy water saver is a recirculating toilet. I had one in my previous Travco
and really
liked it. I haven't seen a hot water recirculating system on an RV. You could
catch the
cold water in a pan and use it to wash dishes etc.

Gardner,

Form my post last night:

It seems like Kathy and are in cold weather a lot and many times dry
camping. I hated to waste water getting hot water to the shower so I routed
a return line from the shower back to the water heater. I then placed a
relay on the pressure control switch of the primary pump to control both
pumps. If the primary pump is running the recirculation pump is off. If
pressure is up and the primary pump shuts off then the recirculation pump
runs. When you turn the pump switch on before stepping into the shower you
have instant hot water. It works well for it's intended purpose to conserve
water but I don't believe that it would keep the cold water side from
freezing.

Chuck,
Thanks. By the way, My wife's name is Kathy also, so it seems
that wives named Kathy like the solution, so it must be a winner.
I like the idea of using relays so that the pumps don't fight each
other. I have a similar relay logic system in my home. The garage
and bedroom share the same supply side for the hot water heating
system, so I built a relay logic system that gives the bedroom
priority. A little boolean logic and some radio shack relays and you
are in business.

Chuck and Gardner:

Am interested in this as well, by why can one not use the cold water line with a
few solenoids as well??

That's a real good idea Bill. Moving water won't "normally" freeze.

Gardner,
I like your hot water circulating idea.
Just a thought on cold water freeze up.
Could you put a seperate water heater in the cold water line with a circulating
pump and set a thermostat at say
50 degrees.

Gardner,

Form my post last night:

It seems like Kathy and are in cold weather a lot and many times dry
camping. I hated to waste water getting hot water to the shower so I routed
a return line from the shower back to the water heater. I then placed a
relay on the pressure control switch of the primary pump to control both
pumps. If the primary pump is running the recirculation pump is off. If
pressure is up and the primary pump shuts off then the recirculation pump
runs. When you turn the pump switch on before stepping into the shower you
have instant hot water. It works well for it's intended purpose to conserve
water but I don't believe that it would keep the cold water side from
freezing.

Subject: [WanderlodgeForum] Hot water and boondocking

We took a 4 day trip and had only power available. I left with a
full water tank and mostly empty grey and black tanks. By the last
day I had about 1/4 tank of water left. I began to think about ways
to conserve water to streach the time we could stay. One thought was
the waste of water waiting for the sink or shower hot water to come
up to temperature. It was cold outside so it took a while, wasted
water and holding tank capacity.

In hotels/motels/large buildings they use a circulating system
that keeps the hot water supply hot so you don't wait for hot water
at the tub or tap. It would seem that this could be done in an RV by
adding a return line from the far end of the hot water system, a one-
way valve and a pump. Then all you would need to do is activate the
pump for a minute or so to charge the system, and then start the
shower. It would conserve the water supply as well as the grey tank
space.

Has anyone seen this kind of system in use?

Gardner,

Thanks to Howard for his cold water idea. Here is a "whole house" hot
water recirculating kit that will do what we are talking about. Crosses
the hot water over to the cold line for it's return trip to the water
heater. No additional return line needed. Just buy an additional cold
water connector for any additional water line runs you may have. The PT
coaches have 2 runs, one down each side of the coach, so this will work.
