Gardaí are investigating the theft of oil burners from homes in the Castlefin area last week.
Three homes in the Liscooley Villas estate were targetted over four days between 14th-17th July.
The valuable oil burners were removed from boilers with little damage caused.
Gardaí say the casing on the boiler was unscrewed at each of the three premises in order for the burglar to take the devices.
“There was very little damage caused by the removal of the burners as it was done very neatly but the burners themselves are of substantial value,” said a garda spokesperson.
Local residents are being asked to cast their mind back and think about any door-to-door callers they may have had to their homes in recent weeks. Residents are being asked to contact Garda if they noticed any unusual cars or people in the area.
“Any small detail that people can remember that stood out in their mind as being strange could assist us with our investigation into the matter,” the garda spokesperson said.
