See the post I made to AZPaints about calculating the absolute theoretical upper limit amount of water that could pass through your meter in a month, versus the "bath a day" soak.

This winter I'm going to rig up a Jacuzzi heater and pump in the tub I rigged up in the shop, inspired by a friend of mine's setup. It cost about $80 for the setup compared to, say, $5000 for a real Jacuzzi plus another $10k to actually build a dedicated building for it.

Then if a soak in a tub is needed, a thermostat could keep the water at, say, 90 degrees f, slowly circulating by using a variable speed drive motor or a belt / pulley or gear setup to move the water through at, say, 2 or 3 gallons per minute.

A field improvised heater is to plumb and wire up (with proper safety grounding and GFCI circuit) an electric water heater element. Probably a 1.5 kw unit is adequate and only runs about $10 or so. You can fit the heater into a section of 1 inch to 1.25 inch pipe and screw it right into a 316 stainless steel T fitting. The pump runs the water thru the T, over the heater element, then into the tub, with the pump intake near the bottom.

You want to have the heater power tied to the pump motor power so the heater cannot be operated if the pump is not circulating water. You could also use a flow rate switch that if the flow falls below a certain minimum safe rate, it kills power to the heater upstream of the thermostat.

It is a little more of an advanced DIY rig, but should be fairly simple and rugged. Also a foot long piece of pipe holding a heater element and connected to a solid earth ground is rather compact and efficient.

For summer use, you might actually even want to run the water through a refrigeration setup to keep it from warming up too much, really important when it's 118 degrees F in the room surrounding the tub.

An old drinking fountain, re-plumbed, makes a great water chiller. You only need about a gallon per minute circulation rate through the plumbing to keep the water cooled to a comfortable level.

Why a new door?

I have a jacuzzi type machine that is shaped like a U and hangs over the side if the tub.

You should collect all the posts you have left all over Delphi and compile a book.

That is even easier to use because it's self-contained with heater, pump, intake and discharge to keep the water from getting cold during a long soak. Just hang it over the side, set the thermostat, and plug it in.

Hmmm. Just what my directions say.

While I don't own one, I've seen them in the past. Don't know where one could buy one today but I might look for one at an estate sale.

I thought you said the door itself is broken. If not, then a new opener should solve it, unless the one you have can be fixed.

Not sure what is broken. Door opens manually. Motor spins but does not move the door. The opener is not that old nor has it had much use. Craftsman was a good brand when I got the first opener.

Sounds like the clutch is not engaging, or there is a broken gear that turns the rest of the mechanism that finally moves the chain that opens the door.
