I have a question I am renovating a house and installing a oil fired boiler. My house is currently 1800 sqaure feet,totally renovated with new insulation,windows etc. I Am planning on a future addition of about another 800 square feet more or less. I went to the local plumbing supply house and asked what size boiler would be right for my home ,they told me a 3 section peerless model . I purchased it and a friend of mine tells me he thinks its too small. I did two online calculations and asked a plumber and the seem to say its ok. I used a calculator on Oil boiler warehouse site which says after my apprx. addition I would need to have 72259.9btu and I downloaded a heat loss program from slant fins site and it says 41,304btu/hr I think that I must be doing something wrong on that one seems kinda low but I am not even close to an expert. My new boilers rating varies from 75 to 131mbh DOE,65 to 114 IBR mbh. I would appreciate any help you can give me

thank you

With both heatloss estimates

you are still within range of a 3 section Peerless . Well ... you will be overfired if the lower number is the right one , but there's only so low you can go with oil ( for now ) . Peerless give you the option of changing the ratings by changing the nozzle size , which works great for the future addition .

Which model ? The WBV ? And most importantly , who is installing it ?
