Re: picts of your in floor heat set ups. Finally got my system up and running about a month ago. It's a 110,000 btu/hr. natural gas fired boiler with an integrated 15 gal. indirect hot water tank. The floor side consists of 3 zones heating 2000 sq. ft. Total of 3250 ft. of 1/2" PEX and it...

If using sprayed urethane, which is a closed cell foam, water will not penetrate it. Foundation crack repair people use urethane foam to seal foundation cracks.

I have a combo boiler that has an indirect DWH tank inside. The pressure in the floor loop side (closed loop) is running at around 16psi. The DWH (open loop) pressure is 70 psi. The expansion tank and air eliminator are on the floor return line, not the supply side. I double checked the...

I agree - yes it is an expensive boiler but I was impressed with the self contained DHW indirect feature as well which made it a simple install that also provides some hot water in the shop. I don't regret spending the extra $$$ and very happy with the system. My build project was more about...

Had a leak develop in the line coming from my system feeder which resulted in pressure loss and system shutdown. I didn't notice it right away so it was probably down for 8-12 hrs. and the slab had already cooled by a few degrees. By the time I got it fixed and fired up again, my 2000 sq. ft...

I use horse stall mats. They are made from recycled rubber and are 4' x 6' x 3/4". They have a channeled underside that allows moisture/water to drain through. Available from most horsey products stores such as System Fencing in Rockwood or your local TSC stores. About $40-50 ea.

In this part of Ontario (not far from you), we put the foam centered inside the foundation wall to extend down about 2' below grade. For example, on an 8" thick wall you have a 3" concrete, 2" foam, 3" concrete sandwich if you look at a cross section. If you already have the walls poured, the...

... also to consider is the MTBF of the LED vs. Incandescent argument. The main reason I have switched to LED is the poor reliability of the cheap incandescent strings. I hate having to go up a ladder in -20C weather to fix the darn things when one of those stupid little bulbs goes south for...

The mixing valve operates as a temperature regulator that prevents the output from exceeding a temperature point that it is set for. Depending on which valve you have, they are usually adjustable. Normally there is a cold water in on one side, a hot water in (from boiler) on the other side and...

Bingo. This is your answer. These are very effective in Northern climes such as where you live if your house is really air tight (well installed vapour barrier and very few leaks). What you could do is have an energy auditor come and do a blower door test to see how air-tight your home is...

For the Canadian winters, my preference is to spray the ceiling from above with 1" - 2" of closed cell urethane foam and then use blown cellulose on top - about 18" to give a good solid R50-R60. With the foam application, it gives the ceiling an air tight seal around all lighting fixtures...

Lining it with white 1/4" "puck board" using the 4' x 8' sheets of the stuff I purchased from a local rink manufacturer. The technical name for it is HPDE sheeting (high density polyethelyne). Really tough stuff but a little on the pricey side - around $40/sheet.

I just had a building designer do up a set of plans for me for a straitforward 26' D x 28' W 2 car garage for $400. He supplied 6 sets of blueprint plans so I could submit them with my Application for Building Permit.

Exception to the above - if the sub panel is installed in a seperate building that has livestock in it (such as a barn with cattle drinking from waterers, etc), they want the sub panel also grounded there with a rod, ground plate etc. and the ground/neutrals bonded there as well. At least that...

Just got my system up and running. One question I have that I can't seem to find an answer to is how I should set the min & max settings for the slab stats. Should this delta be fairly narrow (ie about 2 degrees) or set wider (say about 10 degrees) to prevent more frequent calls for the boiler...

Yes, there is a boiler that heats the fluid that flows through the in-floor tubing (a 50/50 mix of water and propylene glycol). The boiler is a high-efficiency modulating, condensing, direct vent unit from Traingle Tube (Excellence model). It has an AFUE of 92% so there is not much heat...

Just did a tour of the local big box stores. Both HD and RONA carry only the Lithonia brand. HD was cheaper than RONA for the identical part# fixtures. 8' tandem 4 bulb strip light Lithonia TC 2 32 120 1/4 GESB $57.95 2' x 4' 4x 32WT8 bulbs (not included) Lithonia 2GT8432A12 120 1/4...

H.E.Williams does not appear to have any distribution in Canada.

?? empty or dry?

I am just about ready to buy the flourescent fixtures I need to finish off my new shop. Not really jazzed about the reviews I have read on the Lithonia fixtures/ballasts you get from the big box stores (HD, RONA, Lowes) or the Lights of America from Wally Mart. So I went to the local...
