    Internet hydronic parts sellers

    are fine for pipe and fittings and hydronic accessories.  Boilers are a different matter -- you have to carefully read the fine print from the manufacturers.  Many of them will not warranty (or not warranty fully) if mail-ordered.  Find a factory-trained installer for whatever brand you select and see if they're willing to work with you.  Be sure to mention that you're planning to sell the house soon and see if you can transfer the warranty.  Sometimes the factory trained installer can negotiate things that you as a homeowner can not.  If you can get yourself classified as a 'builder,' your buyer becomes the 'homeowner' for warranty purposes.  If you're lucky.

    I was asking for suppliers for the valves etc. not the boiler.

    I've used our contractor's license to get a Cadet boiler quote from the local Lochinvar distributor. I'll discuss the warranty with the distributor and manufacturer.

    The Cadet installation instructions and schematic appear straight forward. I believe I can do the install. You seem to be suggesting that I hire an installer. Are there special skills required that I won't be able to learn through study? I don't trust either of the hydronics "pros" that I've talked to, neither seemed technically competent.

    Thanks for the links...I'll check them out. I'm also reading Modern Hydronic Heating. It has a wealth of info. I'm less concerned about the actual piping and valve assembly than I am with setting the boiler controls properly. I figure that if I use the manufacturer's schematic showing the positioning of the various valves, pump, tank, etc. I can't go too wrong. I'm accomplished at sweat soldering. This is going to be either a 1 or 2 zone system....very basic.
