Rental Clause to Prohibit Space Heaters?

[Barbara McArthur]

My tenants tried to save a few bucks on heating expenses by turning the central heat way down and using space heaters.  When they moved out I eventually discovered that one of my electrical outlets wasn't working.  The electrician said it was a 15 amp breaker and that probably the heater drew too much electricity and burned out the outlet.  He replaced the outlet and upgraded the breaker to 20 amps.  I was stuck with a $400 bill.  The tenants are long gone.  I'm tempted to put a "no space heaters" clause into my next rental contract.  What do you think?
