Control Hot Water Circ Pump With X10?

Hello. My house has a hot water circulating pump built in and located
near my hot water tank. It currently runs 24/7 and this is excessive. So
I would like to put it on a timer controlled by my X10 system. The pump
is wired to a wall switch so I think it easiest to replace the standard
wall switch with an X10 switch. I have done this with many of the lights
in my house so it should be easy for me to accomplish. My question is
which model switch should I use? Is something like the WS467 ok? Or is
there another unit that would be better for use with the pump? Thanks
for your advice.

Use a relay switch rated for high inductive loads, like the XPS3. Check
with an electrician or the vendor if you're unsure. Or use a dedicated
timer like the Instamatic ST01C.

Thanks Steve, the XPS3 is the one I use for controlling some of my
fluorescent lights. I agree that it would be a better choice than the
WS467 I mentioned. I just couldn't recall the other model number.

I presume you meant the Intermatic timer (rather than instamatic). That
is an option. But since I already have an X10 ActiveHome automated home
control module running lights on the house, it just seemed easier to use
that single point of control rather than having another timer and backup
battery to deal with. I neglected to point out that I already had the
home system running.

I do exactly this by having the pump powered though a flying lead with a 110v
plug and then use an X10 appliance module in a 110v socket.

If your schedule is fairly regular and you do not need remote control from
outside the property then a simple socket timer instead of using your X10
system would give a more robust and reliable solution.

Whats this pump is for? Hot wather for heating or for shower or the like?

Cause if it for heating, I wonder why its not controled by some temperature
sensing device that would start it and stop at a fix temperature..

If its for shower or the like ( I supposed its for holding up a constent
pressure????) well just controle it by a pressure switch, if its too low,
just start the pump, and at a set level stop it..

I wonder why you would need x10 if thats any of the case I describe.

This sort of pump is not for the purposes you describe. See
<http://www.hgtvpro.com/hpro/bp_mechanical/article/0,,hpro_20151_5056317,00.html
for an explanation. I am not sure but this may now be code in some
locales if the hot mater run length is beyond a certain point.

Ok got it.. all this to save water.. Here we dont have that problem ;-)

so your problem is that to save water you spend electricity.. So you want to
save on electricity, but to do so, you will now start loosing water with the
use of a switch, making this whole system useless....

I think you should start looking at the problem from an other angle..

Could you use some solar panel to supply electricity to some battery pack
that could provide power to an inveter that would feed the pump, saving
money, and water while keeping the system working and still respecting any
code....

Not just to save water - also to improve comfort by having hot water
available immediately at points of use (e.g. showers, taps, laundry
appliances) without any delays.

Where is "here"?

The switch will stop water circulation at times that hot water is not needed,
such as in the middle of the night and when the property is empty.  That will
tend to save fuel without wasting any water.

That was my thinking too, Tony. I have ordered a relay switch for this
and hope to get it installed soon. They all I have to do is update my
active home routine and download it into my controller. I figure I can
turn the thing off over 12 hours a day since this feeds only our guest
bath. My only concern is if the on/off will impact the life of the pump.

Cheers and thanks to all who responded.

Well, switch received, installed, and tested. I wonder if/when the
savings will cover the $11 cost plus my time? Cheers!

In Quebec.. we have water to waste..But I dont waste it..

thats ok I understood the system, of course all this hot water circulating
in pipes all day long will heat the house as a draw back, and at the same
time consume fuel for heating the water back to level, and electricity for
the pump, and we need to cool that house down.. all this to save some water,
and have a little bit of comfort... Geee.. really I think this whole Idea is
a damn lost of resource..

One's level of comfort and whether to have any running hot water or whether
to have it available immediately, will depend on one's level of affluence and
where one chooses to allocate it.  That you can't afford or don't choose to
afford such a system is no reason for you to denigrate the choices of others.

I dont denigrate, In fact I have a spa that run all year long.. and when its
minus 25 here the water is still at 100... But I dont try to save a few cent
a day, if I chose to have some confort. its either, you understand that its
will cost you to have the comfort, or you can save some money and have to
wait 10-15 secound to have hot water in the guet bathroom..

trying to cut down on such small amount is purely trying to squeeze a few
drop of juice from an old orange when you have a good supply of it and wont
be in shortage soon..

When I added a recirc system to my house, I added low voltage wiring from each
room needing hot water, with a push button there. Push the button, and it turns
on the pump long enough to get hot water to that fixture. So the pump almost
never runs, but hot water is fully available half a minute or so after you enter
the room and push the button. Ypu could use X10 commands to do the same thing, I
suppose, avoiding the low voltage wiring.

I checked with my sister who has a nearly identical system to yours in
her house. I agree that this is an ideal solution to the problem. Now
that I have the pump on X-10, I could put a controller some sort in the
guest bathroom to provide a manual, on-demand run of the pump. I would
just need to find an X-10 controller that can send an on signal followed
by an off signal after an appropriate delay. I could use Active Home to
do this sort of thing, I think. But I do not want my computer running
all the time monitoring for this.

Don't some of the X10 motion detectors do that - send an on signal followed by
an off signal.

That's an interesting idea. Thanks!
