Title: Logstor installation questions
Post by: morfem on June 26, 2017, 06:43:42 AM
A few questions regarding the installation of Logstor pipe or any other insulated pex for that matter.

I will be making 2 runs. One from OWB to the house and one from the OWB to the shop.

The one to the house will be going through the basement block wall strait in so I wouldn't have to add any length for the bends.

The one going to the shop will have to be bent up 90 deg along with the 2 going into the back of the OWB and the one going to the shop.

1- How much pipe do you recommend sticking inside the basement wall?

2-Is there a good way to seal up the pipe going through a block wall? Do they make any fittings or do I just seal it up with caulk?

3 - How much needs to be sticking up where the OWB is set?

4- How much length to add for each 90 deg bend up?

5 - How deep to bury pipe?

I do not want to cut my self short on ordering enough pipe but yet I do not want to be throwing a bunch away since it is so expensive.

Any other suggestions or pitfalls to watch out for?

Hydraulic cement works well for sealing where we come through basement walls.

We rarely go deeper than 24" unless there's heavy traffic on top. It's circulating insulated piping, not like a well line. And I doubt you're much colder where you're at than western VA as we're higher elevation.

Edit: We're USDA zone 6a, southern Indiana is 6b, so very similar.

Ditto on the hydraulic cement and depth. If desired it can be left open at the basement wall for a few days then foundation sealer brushed on the outside.

Logstor is some tough stuff to bend, use a 1” ratchet strap to help convince it, I went deeper at the stove end so it came up straight as possible. Use binder twine or cord to tie to the bottom of the pipe then hook your ratchet strap above ground, but off any twine or cord above ground once backfilled. Allow five foot for the radius at the stove and shop, how much inside is up to you. At the stove steel pipe, copper pipe or 1” heater hose can be used to make connections from the stove/pump to the Logstor. Or you can leave enough extra Logstor and hook it directly up.

What is the outside diameter of the assembled insulated pipe?

How big of a hole would I need to bore in the block wall?

about 4-3/8"

A 5 inch core bit works perfectly abs seal it with hydraulic cement.

If you have the ability to bury it below the frost line, I think I probably would do that.

You can if you want, not any real point in it though, here we’ve had the old water lines that were buried at five foot freeze before, new ones are at 6 foot.

When I did mine we had a mess at the corner by the house, hit an old tile and a new tile, old tile was plugged and soon as we cut it trench filled with water from everything backed up in it, left the trench open till it dried out and settled. The Logstor was exposed for awhile, more than once I had snow or ice on the Logstor that never melted till the sun was out long enough to do the job.

Agree ...

My neighbor had heated for 3 or 4 winters with pipe laying top of the ground about 75'. Barely melts snow, mostly from sun. Power outage would freeze the pipe tho, but he has a generator. Hasn't needed it yet.

The frost line here where I live is 46" so I buried mine at 50".  Really not too deep using my backhoe.  I suppose it would be a pain to dig it back up for any reason.
