100% depends on the insulation of the apartment. I live in a very well insulated first floor apartment and keep the thermostat at 65. I fill the oil tank once a year.

Is the hot water on gas? It definitely helps if heat is the only thing running on oil. Then you only have to worry about it in winter.

I wouldn't trust the number you were given. There's too many variables at play.

Hot water is oil, too, unfortunately.

That’s not technically a bad thing. The system is a closed loop. Hopefully a plumber reading this and will assist with an ELI5.

In the winter it's definitely not a bad thing. Because then your heating plant is doing two for one.

And in the summer that's the only reason it uses oil, and, depending on how hot you take your shower (or how hot you set the water heater at), it's only every couple of days for just a bit.

Now, having oil heat and electric water heater at the same time. That's stupid.

That’s gonna be way cheaper than electric right now

No its not. Theres no way that a landlord is installing an oil fired water heater for ~$3000 when theres already gas in the building.
