Calculate btus for OIl and Gas steam
Hi I have a 200 year old house and have done some work to update the insulation in the walls and windows and doors. I have a oil fired steam boiler from like around 1950's I havnt decided to stay with oil or go to a new gas steam boiler just quite yet. I went to Utica site and found a calculator to determined the amount sq ft radiation I need. I need 725 sq ft of radiation, but before I call in a steam boiler specialist I have 2 questions hopefully can be answered. 1 how many btu's will I need so I know the person I hire gives me the right amount of btu's and 2 If I decide to convert my radiators to hot water and use a high efficient gas boiler like Viessmann how do I figure out that amount of Btu's as well. Also there is no water tank being installed that is completely temperate.
