I have a Vancouver Special with the poly-b tubing, and it's cost me a pile of money over the years. The poly-b allows oxygen to enter the system and causes the boiler to rust. There's always a problem with it, usually on the coldest day of the year and it seems to happen every year. I had a Super Hot put in by a neighbours relative 4 years ago and when they left, I had 2 blocked zones and piping that was installed incorrectly. Don't know why the zones got blocked but I think he may have disturbed the crap in the lines when he was bleeding the system. I managed to clear one of the lines but not the other because the rust flakes from the original cast iron boiler was all jammed up in the line under the cement slab.
He told me there was a five year warranty on the boiler but neglected to tell me only if there is no poly-b tubing involved. Then he never answers my phone calls or returns any of my messages. Learned my lesson, go with a knowledgeable company with good ratings. It will cost more but hopefully worth it.
I got an estimate today for a properly designed system with a heat exchanger and basically two pump systems. Takes 2 days to install and all the poly-b connections in the house are changed to the approved ones. 10 G's before taxes. Ouch!  This includes permits and inspection by the city and carries a 10 year warranty provided I get the system serviced every year.
The only good thing about this is that if I ever sell the house, the inspector cannot tell a prospective buyer that it would cost thousands to convert the system. Yeah right..............I've already paid it! But I can now tell my insurance company that there is less chance of a flood claim. |
you can never ever get rid of all the poly Bs in your house if its radiant heat.
How you change out the pipes in the floor? They can just replace whatever thats coming outta the ground to hepex or oxypex for that matter. Best bet is to put in a stainless steel or copper heat exchange or just a plain heat exchanger for that matter.
Whoever told you that they are going to replace all the poly Bs in your home is lying to you, UNLESS ofcourse they jackhammer the whole house's floor, run new pipes and repour, which in that case, 10Gs sounds really cheap:P
