NORWALK - Local heating companies say their staffs are busier than normal handling hundreds of heating problems as temperatures drop.

Santa Fuel in Bridgeport says they received more than 800 calls from homeowners on Tuesday.

Santa Fuel President Peter Russell says that some oil, electric and gas home-heaters are not able to handle the colder temperatures.

Russell encourages homeowners to call with concerns and also advises homeowners to watch the temperature of the thermostat.

"Turning it down is going to save you money, but we recommend that you don't turn it down any more than 8 degrees," says Russell. "Once you get beyond that, you are just spending more energy to get it back up to temperature than you would."

Most heating companies told News 12 Connecticut that they have staff ready to handle late night calls.
