The easiest way to determine how much energy it takes to heat your house is to take a reading of your gas meter at 8:00 AM each day for two or three days during your coldest weather period and record the amount of gas used each 24 hours. Then knowing the volume of gas used each 24 hours, multiply the volume by the heating value to determine the energy used. Divide by 24 hours to get the average input per hour. Add 50% to that and you will have enough capacity for any winter day.

You can also record the volume used during a short period of time that the heating device is on, 5 minutes is what I used, and determine what your current rate of energy input is. This can be done any time of year.

If that was the intended question the answer is. . . probably.Natural gas and Oil fired boilers come in many different configurations. For the average home there will be many which will be large enough to meet your needs and also fit through a standard exterior door.However, boiler sizing is very tricky and should be done by a professional, (not to mention installation) Most suppliers will do the sizing for the pleasure of selling you a boiler, and most work closely with the installer to make sure that it gets installed properly.More information on boiler installation and sizing can be found at http://www.heatinghelp.com/With a little reading I am sure you will convince yourself that hydronics can be as tricky and technical as any medical procedure and you will probably not want to tackle it yourself.

It is the number of BTU`s per hour lost by the home due to lack of insulation, doors without weather stripping, inefficient windows and many other factors.
