How to size and sell a Navien tankless

Keep those questions coming, it helps me make videos. There is no magic spell or a crystal ball to help size or sell and product, there is knowledge you can get to help you to sell a produce. Sizing is easy just follow what I have laid out and Bobs your uncle.
Remember to keep all the booklets with you and photos to give or show to your customers, The installers manual will also help you in the future when repairing a unit.
