Furnace intallation

I’m looking into replacing my 20+ year oil furnace but so far I’m very confuse with contractors not giving me the story on what needs to be done. One claims that the pipe going from the furnace to the chimney is to long (about 10’) so the furnace needs to be moved and another one the furnace is find where it is but the liner of the chimney need to be change because there is an increaser at the entrance of the chimney from the pipe. Can someone direct me where I could find the rules and regulations for that kind of stuff? I live in Ontario.

Also just for your info the chimney liner and the pipe (double wall) was changed 4 years ago.

It sounds like you are pursuing an 80% efficient furnace.

Since you have a new liner I would assume it is sized right, but could change with size of new furnace.

Being ten foot from a wall in my area (not far from Ontario) with double wall vent should be ok. I would need size of new furnace check the size issue.

Get me the new furnace btu rating and diameter of existing liner.

Cheers,

Manhunter

I got two estimates so far (will be getting at least 3 more) both only quoted the work that will be done with the price and yes I'm looking for a 83% or better

I will get the info you required (btu, diameter ...) in the next few days and post them here.

Thank you

Estimates



People don't get enough estimates get a whole page full why not they are free and besides that pick their brains while your at it.
Make sure they are insured (look at insurance certs). Make sure you get referrals and call them( possibly look at the work). Sounds like a couple rip offs to me.

I would be leery of them. Always a bit of sulphur in the smoke which will be in the condensate? turn into sulphuric acid?eat the condensing coil? Have never seen one so I may be wrong, just theorizing.:whistling2:

TS37, have you checked with Ontario Hydro about the cost to heat your home with electricity, or electric furnace and heat pump VS. oil. It is a lot cheaper to go electric in Manitoba, oil is ridiculously expensive.

Are you looking for a new oil furnace or converting to gas?

More trouble with the secondary HX clogging, then rotting out.

Some of them need to be cleaned twice a heating season.
If the nozzle starts to lose just a little of its spray angle, they soot up real quick.

Worked on a couple of them. PITA

Welcome aboard Manhunter.
Beenthere is our most knowledgeable oil guru (I used to do oil years ago) and it sounds like they make high efficiency condensing oil furnaces/over 90%. There is no 83% efficient gas furnace. Sounds like there is confusion over which fuel our poster is burning.

Found one:http://www.adamsmanufacturing.com/products.html

Very good.
But with in the US the highest level of efficiency that may be achieved is 83%.
Of course the actual operational efficiency is below the 83% number to avoid internal condensation which would destroy the insides of the furnace. Many years ago HVAC operator-owners were presenting 80% models as 83%- whether thru ignorance or fraudulent intent. The 83% number has persisted in some areas of the US.

That, at least is what I bring away from it.

Cheers

Please follow Yuri's link.
90%+ furnaces have been in the USA for a long time now.

They ARE a PITA, but they are out and installed in homes.
