Add-on Wood Boiler

[Marshy]

I'd like to make most of the plumbing with Pex but the zone valves, isolation valves are all sweated connection so I'm not sure there is a savings.

I've already been on Supply House, great site. I'll likely be placing an order through them.

Can anyone give me some suggestions on where to source the insulated pex used for direct burial (or name of manufacture)? I'll be using 1-1/4" and have less than 50' run.

Thermopex or Logstor are I think the two most common.

Some guys have been finding it at their local OWB dealer. But a lot of OWB dealers sell the stuff you want to stay away from too.
