Commercial Water Heaters, a leading online distributor of commercial water heaters, recommends that home and business owners inspect their water heaters as the transition to winter brings cooler weather and a greater risk of damage from frozen pipe systems. The Santa Ana, California-based company recently received a large shipment of its most popular models in anticipation of the changing seasons. As the temperature begins to drop, water heaters must work harder to produce heat, causing additional stress to pipes and plumbing.
