My House - Part II

[Roger M]

Thanks for the offer and support! I've heard the staple up systems work great.

I'm looking at a Peerless Pinnacle 80 with a PP-40 tank. I want to get my domestic hot from the boiler too do you think this will work?



I've heard good and bad about this boiler. Any thoughts?

What did you insulate your crawlspace with? I'm going to put batts in the joist bays and then I've heard that foil double bubble foil (FDBF) is the way to go for the vapor barrier.

I've heard of the Peerless boilers, but they are not common up here in the Northwest. I install Buderus, Weil Mclain, Veissmann, and a few other brands.
Heating your potable water with the boiler is a great idea. The recovery time is much faster than an electric or gas water heater, and its much more efficient. Just make sure you size the piping and pump properly.

As far as insulating, I used the double bubble foil and cut it in widths about 1.5 inches wider than the joistbay. Push it up to where its about an inch away from touching the tubing. Staple it to the joist and then insulate under it with batting (R19 or R21).You dont want the bubble foil touching the tube or the subfloor. The Idea behind staple up is that the tube heats the insulated airspace and the bubble foil directs the heats upwards. You need to make sure that you seal that airspace good so none or very little of the warm air escapes.

I could ramble on more, but I'll save it. If you have more questions, feel free to PM me. Glad to help if I can. Good Luck with your project
