Hot water accounts for a large percentage of your home heating costs. Keeping your gas water heater running efficiently can save you a significant amount of money. Wesco Energy’s technicians can recommend and advise you on a hot water heater that will both save money and be highly efficient. When purchasing a gas water heater, look for one with a 10-12 year warranty as that’s the life expectancy of the gas water heater. Having “clean” water will also improve the efficiency and extend the life expectancy of the gas water heater as it “hard” water can take a toll. Brass drain valves and glass-lined tanks are additional features you should consider in a gas water heater. To monitor the operation of the gas water heater you should consider a digital display.
