Heating system

[63bird]

I have 2 apartments upstairs in a 4 family house with hot water baseboard heat.
The 2 apartments upstairs are in one loop system with 1 thermostat in 1 apartment , is there a way to add another thermostat in 2nd apartment to regulate heat in 2nd apartment as 2nd apartment is colder then other.

Add another zone pump and control panel and separate the loops.

I'd post this in Home & Garden.

Move the thermostat to the colder apartment then in the warmer one, connect a thermostat to a solenoid valve you put in the hot water line, or just put a manually adjustable valve in the hotter one to decrease flow a corresponding amount (easier way), but you need to still move the thermostat to the colder apartment.

Chances are when the place was built it had thermostats and zone valves in all the units. They normally end up with indoor outdoor controls on the boiler and the zone valves manually opened so the landlord can save some money. Chances are the tstat in the warm unit doesn't really work and the cold unit just needs bled. If thats not it I'd be looking for a zone valve that isn't open all the way in the cold unit.
