Before we start talking about why your furnace is leaking water, please be sure that it is your furnace leaking water. Nothing is worse than going through all of these steps, getting frustrated, and calling your energy company for service, just to find out it’s not your heating system.

Gas Equipment

Floor drains being clogged with debris are one of the most common issues that can cause your furnace to leak. To fix this simply check the drain in your equipment and make sure there’s no blockage, and if you find any debris clear it out.

A flue pipe is the furnaces way of expelling any byproducts that come from normal use. If you have a flue pipe that doesn’t quite fit or has wear and tear, it might be the source of your water leak. If signs lead to this being your issue, give us a call at (207) 947-3835 and we’ll be happy to help you out.

Routine maintenance is important for many reasons. One of those reasons it that your furnace’s condensation-bearing pipes could be starting to show their first signs of long-term use. Many of these pipes use either insulation or tape to keep condensation from escaping, and once that barrier starts to wear down, it’s easy for drops of water to accumulate over time.

Oil Equipment - Expert Advice

Oil equipment can be much more complicated. Here’s a word from Matt LaForrest, one of our Certified HVAC Service Technicians at R. H. Foster:

Oil units do not usually have any sort of condensate drain on them. I would amend that to say that any water leaking from a heating system is something to not panic over, but for sure call a professional to look at the situation. The possible causes of any water leak are multiple and sometimes confusing. The best advice is to have the consumer judge the volume of water leaking, judge whether it can wait for service with putting a bucket under it, and assess the area it seems to be leaking from. Note that all boiler systems should have a means of which to shut the water off to the unit should it require immediate attention, such as when water is pouring out of the unit.

** If you shut off your water to your system, please remember to also shut off the system. **
