So here is what I'd like to do and hopefully someone can set me straight.I want to get a 200+ gallon water storage tank. I have an indoor wood furnace which i will heat the water to 180 this will circulate through our oil furnace and use the oil furnaces blower to heat the house. My plan is to only burn wood twice a week to heat the water then have the water retain the heat a couple days to heat the house. I think I will need a pump and a thermostat to control the oil furnace and circulate the water. And a radiator of some kind to put in the oil furnace duct work. My furnace has pipes running thru it to heat hot water for showers and such i'd like to use this to heat the water in the storage tank. Help Please?
