After installing hot water tank insulation, you can immediately start saving on utility costs. Insulation helps hot water tanks keep heat better, so the water inside stays hot longer and is more readily available. Because tanks with insulation maintain a more constant hot water temperature, the heater won’t have to reheat water as often. The equipment then requires less energy to operate, improving efficiency.
Hot water tank insulation is especially important if your equipment is in an unheated or cooler area, like a garage or basement. In these situations, Synergy’s San Diego division manager, Casey Davis, says installing tank insulation is like bundling up when it’s cold outside. “Putting on a jacket or adding another layer of clothes keeps you warmer because each layer helps you save body heat,” Davis said. “That’s exactly how it is with water heater insulation and water temperature.”
Cost and energy savings aside, insulation has the extra bonus of extending the lifespan of your hot water heater. More efficient performance lessens the demand on the unit. Insulation can help prevent standard equipment wear and tear and keep your water heater running longer. “You’re not only going to save money because your water heater isn’t running as often, but you’re also saving on equipment costs because you won’t have to replace it as often,” Davis said.
