Snowmelt over Pavers

steveex

Yes it is, typicly pavers will take twice as long as cement for snow to melt. Lets say you have a simple ETI snow switch which has a 5 hour on time, you would want that kind of start. Like a 442-w30 off the line. Brooklyn by the way, thanks

Edit: I should have said, "Snowmelt UNDER Pavers"

The Interlocking Concrete Paver Institute has these specs on their website pertaining to snowmelt systems. Anyone else have experience with pavers that did not specify insulation above grade and below the pavers?

The 2nd attached picture is right out of the Uponor snow and ice melting design guide and I am stating that we MUST use an R10.

Does anyone think that this ICPI might be a little reckless in having these types of specifications available? Response time must not be an issue according to the ICPI.

This would be our first concrete paver job with snowmelt so I am just curious as to what my peers have seen.

Paul, Physic's are physic's , You are specking R 10 As edge/ Base Insulation? Otherwise you may have Tulips growing in January! A snow melt "wastes" a lot of energy as it is. so yes contain as much as you can, given it does not effect the structure, i.e. edges breaking out!.. If you need more infomation maybe you should tank to some of the Ski areas Like Copper Mtn.CO they have some "big" systems i think they have Pavers to, All is driven by some nice Vertomats!Good luck .Richard from Heatmeister.

Paul you can get away with 1 inch polystyrene dow board, sometimes height is an issue,would perfer 2 inch, however 200 - 300 btus a foot a must.

300 BTU/sqft under what circumstances ?That is pretty ex stream do'nt you think so? where do you live ? on the North Pole?

Derheatmeister

Steveex, Sorry but even with higher wind loads ( And we are up in the Rockies!!) We do not use that many BTU/Sqft. Maybe 160 BTU/sqft.! That seems a little high! HM.

Mr. Heatmeister I currently have systems operating with 100 btus a foot, they work fine on small accumulations, in the event of 1 to 2 inchs per hour there will be build up. Now where i do most of my jobs the best advertising is clear sidewalks and driveways. My systems at 250 per foot are worth every penny. And melt snow the first half hour.

What type of heating source do use out there. Snowmelt that is.

Steveex For Snowmelt.PK's Viessmann,TT. Maybe your"Wet" snow on the east coast was something to do with the high BTU Input?
