The rental property I am newly occupying is heated by an electric boiler that feeds to an exchanger in a forced hot air system. Even in the summertime when no heat is required, the 5' by 4' room where the boiler and air system are contained is noticibly warmer than the rest of the house. It seems as though the boiler (which is also tied into the electric water heater in the same room) runs in a stand-by mode to provide instant heat if the themostat calls for it.
Is there any way to reduce the waste heat generated in this room (and therefore the additional costs) especially during the summer months?
Can the boiler be turned off? (I tried the main breaker for the system but this also turned off the hot water heater.
Are there any tips for using such a system to get the most economy and yet have heat and hot water when needed?

There seems to be switching issues with your installation. Appliances should have dedicated circuts. That would enable you to safely shut off the power supply to your boiler for servicing.
Check your local codes you are probably in need of some compliance upgrades. Also check your appliances warranties. Not isolating the power supply may give them cause to void any claims.

It sounds like your boiler is also feeding the hot water tank. The tank doesn't actually heat the water, it is just a holding tank for hot water. That would explain why the hot water turned off when you shut down the furnace.
You should be able to shut down the boiler in the summer, if it's a stand alone system, used to just heat the house.
If in doubt have some one come in and check it. Pictures would also help a lot.
