Heat Loss Analysis

Request For Heat Loss Analysis

My house is an 1861 Empire Style Victorian. It is basically a rectangle house with two small rectangle cut-outs. The exterior wall lengths are as follows:
front: 20'
porch cut-out facing right side: 16'8'
porch cut out facing front: 10'5"
right side: 29'
back 22'8"
left side: 28'7"
rear cut out facing back: 8'2"
rear cut out running facing left: 14'
total linear feet = 149'6"
I added a 10’ X 4’ addition onto my kitchen in 1991. For some reason I have a cold kitchen.

The house has an unheated basement, a first floor, and a second floor. There is no attic. I bought my house in 1985. In the 1980’s, I blew insulation into the exterior walls and the roof crawl space. There are two circulation vents on the roof. There is a chimney stack. (I plan to build a 30’ long addition in the future with three garage doors on level one and walk-in closets and a recreation room above.)

The basement has no heat, but houses the water boiler. There is one basement door and two basement windows. A cold 10’X 4’ cubby hole is under my kitchen addition

The first floor has four rooms and one bathroom. Windows include: three 81” X33” windows, five 67” X 33” windows, two 48”X 33” windows, one 36”X48” window, and one 34”X26” window. The first four had three exterior doors, two are wooden originals with glass panes and one is steel covered door. The front door is drafty from a worn threshold. The first floor also has one kick board blower in the kitchen and seven radiators as follows.
One 2’H X 30”W (12 sections, 2 columns)
Two 40”H X 20”W (8 sections, 2 columns)
One 40”H X 41/2’W (22 sections, 2 columns)
One 40”H X 21”W (10sections, 2 columns)
One 20”H X 41/2’ (21 sections, 2 columns)
One 2”H X 12” (6 sections, 2 columns)

The second floor has baseboard heat that was installed in 1991. The baseboard runs along the perimeter of the exterior walls. The baseboard is copper tubing with fin tubing running the whole length of each wall. There is only about 6 and1/2 feet of dummy baseboard running in closets and, of course, there is additional dummy baseboard traversing through walls. The second floor also has eight 1980 vintage aluminum replacement windows, 48”X32”. They are all broken, drafty and need to be replaced. There are also two 34” X 33” wooden windows and two 48” X 32” wooden windows in the new master bedroom, which was built above the old kitchen in 1991.

Can you provide your heat loss analysis for the current as is house and then provide another to account for the addition? The addition has not yet been architected.

    Tough to do over the net

    There are a lot of things that enter into the final number besides what you have listed. House orientation..East, South, North........, amount of insulation in the walls and ceiling, type of windows, even the color of the roof.

    The most accurate would be to hire someone to perform this work for you. You can also do a basic calculation yourself with the download provided on the main page of this website. I believe this has been courteously provided by Slant Fin boiler company IIRC. If you use it, send them a thank you.
