Heating for Investment Property

[Juan Zabala]

I own a mixed use 3 unit building that has a gas steam boiler in it. The property is 3,000+ Square feet and 3 floors. I am having a hard time heating the back units because the steam is not reaching those radiators. My tenants are complaining because the space heaters that I gave them as back up heating are costing them too much. I've been trying everything to try to solve this heating issue. I pay heat as the landlord, and the heat can range anywhere from $300-$600 a month. I want to be fair to my tenants while at the same time trying to curb cost of the building for myself. Has anyone experienced this issue with their property? What did you do? What can be done? Should I switch to baseboard electric heat in the building? Should I add another boiler in the building? What alternatives are there to make a more cost efficient heating system? And help to stop my clients from being left in the cold. Any help would be greatly appreciated. I've been trying to wrap my head around this because I'm paying a lot of money in gas for an inefficient heating system. Thanks in advance!
