Plumbing services are best left up to the professionals. DIY projects can easily go horribly wrong and lead to a great deal of inconvenience, damage and expense. Licensed plumbers have the training, specialized tools and resources to handle unexpected issues and complexities. The help of professional contractors can reduce the amount of disruption and mess caused by repairs, replacements or installation. Rather than grab a water heater off the shelf of a home improvement store, it’s better to consult with a knowledgeable contractor. A plumber knows how to calculate the proper size for household demands. He should be familiar with the make and models and recommend one of better quality. While all tank-style water heaters might appear the same, there are significant differences that add to convenience, value and satisfaction. The heating element affects how quickly the water heats up. The anode rod helps to remove hard water chemicals. Warranty coverage is also important. An experienced plumber can potentially fix the existing water heater, provide life-extending maintenance and helpt to determine if conversion to tankless would be feasible. Tankless water heaters are about the size of a small suitcase, mount to the wall and can be installed indoors or outdoors. The system heats water on-demand and eliminates standby energy losses. Because the water isn’t constantly reheated in a tank, it doesn’t absorb harmful chemicals. Plus, there’s no waiting for water to heat up and no running out of hot water. Tankless water heaters also offer a much longer lifespan. Like all water heaters, maintenance is essential to performance. Having service performed by a licensed plumber every year fulfills the warranty requirements.
