Tenant has COVID but the heat is broken.

[Tristan Scott Zell]

I have a tenant who just got Covid and is quarantining inside the apartment. They notified me that also the thermostat is broken and they aren't able to set it to a reasonable temperature, this is not good since as the landlord I need to keep the heat at a certain temperature (Right now in Maine temps are in single digits). But it doesn't make sense to send anybody in there to fix it if the tenant has covid. What should I do? I am thinking about getting a space heater and giving it to them to use, but this is only a temporary fix.
