I've owned a 2-flat (live in 1st floor, rent 2nd) for about 1.5 years and trying to balance the radiator heat is driving me crazy. During cold winter days, we have a sauna in the front of the building and a meat locker in the back. I've tried regulating heat by stopping down the front radiators with only limited success. My two key questions:
1. is there a way to better regulate the system (or perhaps something additional that should be installed?
2. Is there any type of water temperature booster for toe-kick type heaters?
The system details:
• 2 year old boiler (Weil McClain 175,000 btu, 83% efficiency)
•*water based system - not steam
• was originally gravity fed. Now has pump, but still uses the large pipes from original install (100 years old)
•*From furnace, pipe splits - 1 side = 4 LR radiators (2 per unit). Other side - remainder of unit (total 16 radiators).
•*Thermostat in front of building. When it reaches 72, back is still in mid 60's (63-67).
• Toe kick in 1st floor kitchen rarely kicks on because it needs 120 degrees. The system often doesn't reach this temp.
There is a diagram attached of the system. If you have any suggestions, it would be greatly appreciated. Thanks for your time!
