Just like the air conditioner and the furnace, the hot water heater has been almost always moving and keeping the house comfortable, yet it is just simple to overlook since it just sits in there and does the job, yearly, in the years to come. Though it is really nice to have a less thing to be anxious about, the water heater will not last that long, and you will have to pay some more attention to it, particularly, as it starts to age.
