Replacing the hot water coil in the furnace
In areas where there is a lot of lime or other minerals (or hard water), it may be
necessary to clean out or replace the hot water coil in the furnace. Thankfully, this is an
easy job. On some other models, it can take 2 hours or more to do this – if they even
have
a built-in coil!
The water coil is under a steel plate at the back/top of the furnace. We’ve lifted up the
insulation to make it easier to see.
