One of the most important innovations developed within our industry in recent years is definitely the tankless water heater. This exciting new product has already begun to revolutionize the way that Canadians clean house, shower and live in general. This is due largely to major changes in hot water availability, space requirements and energy efficiency. However, many people still don’t know how these mighty yet mini water heaters work. With that in mind, here is a closer look at tankless water heaters.
How do they work?
Unlike traditional water heaters, which hold and heat large quantities of water, tankless systems heat water on demand using a heat exchanger. Activated by incoming water, the heat exchanger eliminates standby heat by efficiently heating cold water to a pre-set temperature. This is done with the help of electric coils or a gas-fired burner, depending on whether you choose an electric, propane, or natural gas model. Beyond that, there are two types of tankless water heaters:
These are typically electric, small, point-of-use systems that fit under cabinets or in closets, and provide water for up to two outlets. Unlike whole-house systems, they have less lag time due to their proximity to the outlets.
Larger and more expensive, these systems can serve your whole house at once and are often fueled by natural gas or propane. They have a much longer lag-time, however, sometimes up to several minutes depending on your plumbing setup. In addition, for simultaneous, multiple uses in large houses, multiple systems may be necessary.
While tankless water heaters are considerably smaller than traditional boilers, it is still essential that you contract a professional to have one installed in your home. You will also need to speak to qualified professionals about selecting the model that is best suited to the size of your household and your particular lifestyle. This is important because there are several factors that need to be customized, to ensure your utmost comfort. These factors include: the volume of water the unit is required to heat, the temperature of cold water entering the tankless hot water heater, and the desired temperature of water exiting your tankless water heater.
