The two most common types of water heaters we see are gas and electric systems. A gas water heater uses a pilot light to ignite the unit, and when this component is malfunctioning, it will be unable to provide the house with hot water. Alternatively, with an electric water heater, a tripped circuit or a blown fuse could point to reasons why the water heater refuses to work. Our San Diego plumbing service company at HPS Plumbing Services can locate the problem with your water heater, and no matter if you have a gas or electric unit, we can offer support and suggestions on repairs, water heater installation services, and even water heater replacement services if necessary!
