As an installer, technician or contractor, you will have noticed tankless water heaters have become very popular in recent years. These units, however, can only achieve the best results if they are properly sized and correctly installed. In this article, I’ll go over some of the key benefits of the units, as well as tell you exactly what to do to ensure a successful installation.
First of all, the benefits of installing a properly sized water heater are many. Topping the list is something your customer can understand right off the bat – they have up to 99% Energy Efficiency ratings. (Meaning simply that 99% of the energy that goes into them comes out the other side as hot water.) Properly sized tankless water heaters are incredibly energy efficient, primarily because they are not subject to the standby losses – heating and re-heating a tank full of water all day long whether there’s demand for it or not — associated with storage heaters. Even ENERGY STAR storage heaters typically waste roughly 33% of the energy they consume.
