Tankless Water Heaters

On this episode of The Build Show Podcast, Matt and Tim Greer do some myth-busting! Tim Greer works at Rinnai, and they get nerdy and dig a little deeper into tankless water heaters. You'll hear compelling arguments to move to tankless, including outdoor mounting and the lengths Rinnai goes to protect its units from freezing. They also debunk some of the myths out there about tankless water heaters and really run the numbers: heating deltas and shower-head flow, traditional venting vs. PVC venting, and more.
