Conventional water heaters are the most common water heater in use today. Tankless heaters don’t contain a storage tank like conventional water heaters do. Instead, a gas burner or an electric element heats the water only when there’s a demand for hot water. In comparison, a conventional water heater consumes energy even when no hot water is being used. ComfortAire can help you with the pros and cons so that you can find the right system for your home.
