LP has a heating content of around 91,000 BTU's per gallon. Natural Gas is sold by the therm and each therm is about 100,000 BTU's. If you can get low sulfur (under 500 parts per million) heating oil, that is a slightly cleaner fuel than LP and natural gas. If you compare LP with heating oil, I think you will find it is less expensive to heat with oil. An oil boiler with as low water content as possible with an indirect for your domestic hot water should serve you well.

    boiler replacement

    Hi, I am looking into replaceing my current hot water boiler. I currently have a lp gas boiler and lp hot water heater. We have baseboard hot water heat. I think I want to replace both units with a new boiler that has a domestic coil. we have a small house with one bathroom and dishwasher(dont know if that makes a differance). My question is, should I stay with lp or go to oil? Which would work better for my installation? Are there other things I should consider when doing the upgrade? Any suggestions would be helpful. Thanks in advance. Chad

    Even though your HW load is small

    I think its crazy to keep a boiler @ 140°+ 24x365 to keap a coil hot. Get a small indirect WH. Plently of high efficency LP boilers out there. Going oil would be answered by what the price of oil is relative to LP. Remember LP gives you only about 100K BTU per gallon while #2 heating oil generates 140K. Also make sure you have a good chimney for oil. Direct Vent oil boilers are not worth the hassle.
