Hi everyone,
I recently moved into a 3 story brick home with gas-fueled steam heat. I'm having major issues in balancing the heat between floors (3rd floor won't heat enough, 1st floor is so hot I had to close the heat valves entirely... 2nd floor has the thermostat and is just right) In addition my first heating bill seems really high, so I suspect some work is in order. I know these are never perfect, but I'm assuming there is some valve work to do, and I need help selecting properly please!
The house is 22 x 44 feet, and has one main running from the rear to front in the basement in the center of the building. There are verticals in the front, center and another in the rear to go up to the second and 3rd floors. I've made a full diagram below including pipe diameters and approximate distances. Radiators appear original from the 1961 construction and are the smaller fin type. Seems to be only one main vent. No clue if there are others on the 3rd floor because they would be in a wall I'd like to avoid opening if I can! :)
All radiators are ~40" except for the bathrooms which are ~20" and the Entry hall at 35"
Can anyone help me select a main vent and valves? The top floor is all gorton "D" except for a 5 in the bathroom (center of building), which Gorton tells me is ideal. But the first and second floors are a mix of brands and models and I'd like to replace everything for proper balance. Ideally I can use gorton on the radiators as that seems the easiest system to understand and select, but I can use whatever works best for the main vent in the basement.
THANK YOU SO MUCH IN ADVANCE!
