I have been reading this thread for about two months now and finally decided to become a member and buy a coal boiler. There is a lot of great information here. I am very concerned with heating my house next winter. I heat my water and house with propane. I have a propane boiler tied into some baseboard heaters. I was getting $1000.00 propane bills last winter about every five to six weeks to heat my water and my house to 60 degrees. It was miserable and I promised my wife we would not go through that again. I read a ton of threads because I did not want to ask the same question that others have asked, but I am still confused, so here is my question.
I have been looking at the Keystoker KA-6. My current propane boiler has a net output of 130,000 BTUs. The KA-6 has a net of 122,000 BTU with a Gross of 144,000 BTU. Looks like it is close enough to what I have however after measuring all my baseboard heaters and multiplying by four like a previous thread said to do, I came up with 700 square feet of load. The max for this boiler is just under this at 675 square feet. Will this be adequate? The salesman told me it is better to operate a smaller boiler at max power than a larger one that just idles all winter long. Is this true?
I am also looking at the Harman VF3000, it says it will heat 3000+ square feet yet it only puts out 95,000 BTU. According to these advertisements, it looks like the VF3000 would be big enough, but after reading the adds for a Keystoker KA-6 which looks bigger, it looks like that wont even be big enough. Do I have to go to a Keystoker KB-8 or something bigger than a Harman VF3000?
I am on a tight budget, so I don’t want to go too big, but after spending all this money, I don’t want to be stuck with something that is not up for the job either. I would like to get off of propane completely.
Thanks for everyone’s time and help. I need to make a fast decision since the wait time for both models is already out to January of 09’….and I thought I was the only one thinking about coal.
