Here is another online calculator that may be worth a look: http://heatload.rinnai.us/ When it came to performing my heat load calculation for my garage, I discovered that varying the R-value of my walls and ceiling did not affect the total value in any earth-shaking manner. What DID impact my...

This is very sage advice. I did not sink my PEX deeper as I was up-in-the-air about future lift, and now my aprehensions are keeping me from going ahead with buying a lift. My slab is 4" thick, 4000 PSI concrete, #4 rebar at 18", with 2" XPS foam underneath. The PEX is stapled to the XPS, so...

Histguy - There's some excellent advice in the posts so far. I think Danski summed up the parameter boundaries well. I would second the advice of performing a rigorous heat load calc - 10K for the loft with your current thermal envelope sounds about right. I have a similar situation here in...

SlimCookie - I would reiterate CNGsaves and steer you directly away from ventless heater. Moisture is a problem... big problem. Though most garages are sufficiently leaky, other byproducts of combustion can accumulate also. So, first you need to know how big. You can get a crude estimate of...

Daner - You really have 2 issues to contend with - the short-circuited, uninsulated slab, with a well insulated garage above it. Have you done a Manual J heat loss calc? Given your volume, and delta T of 60F, you may find that you only need 20K to 25K BTU/h to heat it, if doors well sealed...

I'd say your $10K price is pretty good too, based on my experience. As for the temperature for "optimal" installation, the word I received, and research I did prior to having my whole house sprayed last month, is "yes", temperature matters. So does humidity. Two part closed cell urethane foam...

Yeah... ....do you tend to use construction adhesive more regularly than toothpaste too? ...like repairing things as much - or more - than actually using them also?

I pre-twist mine, 'cuz there's really nothing quite so rewarding and life-affirming as cranking 4 or 5 bare wires together into one consolidated, buggered up mass of copper. Then I take a jumbo pair of pliers and nip off much of the buggered mass at an acute angle and crank the wire nut on so...

Agreed... they are cheap insurance... for what has become a low risk issue in most places.

Drip legs are an anachronism, from the bygone era of "manufactured gas" which was notoriously dirty. In most places today, natural gas is so clean as to render the drip leg obsolete. Yet, codes are slow to keep up, and in my estimation, left on the books way too long just to give nit-picky...

One pump for primary boiler loop. Then, each zone has its own pump, drawing from the boiler loop into the secondary zone loop. If I had decided to go with an outflow "leg" and and inflow "leg" from and to the boiler, and not made it a closed loop as I did, then I could've gotten away with just...

By the way, in response to earlier posts about proper orientation of Grundfos pumps, it should be noted that I have one pump pumping vertically upwards, two pumps pumping vertically downwards, and one pump pumping in horizontal direction. Pumps can pump in any direction. What matters, as was...

PVC piping over to condensate stack, which I unfortunately undersized at 2"D. Stack is just on other side of ladders, and already has Rusco spin filter drain, mini-split condensate tubing (x2), and pressure relief pipe from H20 heater. Also will drain condensate from future air compressor as...

My Radiant In-Floor Heat Set Up. Finally.... yesterday the POCO turned on the gas, I fired up the boiler, and now...HEAT! A three zone heat set up - 6 loops in the main garage, 3 loops in a 20 x 24 wood shop, and 2 loops upstairs in the loft. 60,000 BTU Triangle Tube boiler. It was 28...

Was thinking of starting another thread, but happened across this one following a search. It's been three weeks since we put Pasco down. He's been with me longer than my kids, and was a constant companion as we began our garage project. We buried him on our lot where we one day plan to build...
