Heat Loss Calculation / Boiler Sizing

I had a local HVAC company quote me a new hot air furnace. The price was $ 6,000.00 for a Lennox or Thermopride unit.

Not to seem arrogant or rude, but $ 4,000.00 for a dual-fuel boiler is a BARGAIN...!!!

If I had plans to keep this house, I would not hesitate to spend $ 4k for a Leisure Line hopper fed boiler or up to $ 8k for an auger fed EFM DF520 boiler.

Joe, are you asking about the gaskets in the stoker or the entire unit?

Rob,

I am only replacing the gaskets around the cleanout door (the one below the DHW plate), the fire viewing door (round door) and the ash pan door for now. BUT, I asked lengths because I want to have enough on hand to replace the stoker unit ones in the future. I don't plan on doing this anytime soon, as this unit has new plates and gaskets installed recently, but I figure if I have to buy by the foot I might as well get enough to do it all.

Thanks,
Joe

Joe, I haven't measured the various lengths to have exact dimensions. The cleanout door and ash door are easy enough to measure/estimate. Note that the ash door uses a 5/8" gasket. For the stoker I think 15" of 3/8" and 40" of 1/4" would be pretty close. Order some extra to have on hand.

I got a few "Rutland gasket kits" on ebay that worked very well for mine.

I used my va400 for the first time last season 2013-2014.

I purchased it about 17 years ago from an 80 year old gentleman that was converting to oil. At that time fuel oil was $0.50 a gallon.

I ran it with the sheetmetal off to keep the basement warm and it did.

My house is 3500 sq/ft and very well insulated using 3/4 inch pex radiant. The va400 kept us warm throughout one if the worst winters in recent history.

I live in Pike County Pa about one hour east of Scranton.

FYI... I buy anthracite coal at Hudson Coal Company near Pittston Pa. for about $180/ton.

Thank you all for this great forum.
