this is an up/down duplex in sudbury -good size -not huge, nor tiny (big 2bdrm upstairs & 3bdrm down with separate dining area). Union gas said it`s similar to vendor`s bill last winter but can water rad heat REALLY be this high? My first winter with this property & I`m not on equal billing - made a mistake of not asking to see utility bills while negotiating/purchasing but I rent it high enough that I`m still positive cash flow after this money drain (thank goodness!) Inspection i`ll review but I don`t think there was major insulation issue reported...
