For many years the go-to method for heating water was with a tank-styled device. Today, however, industry projections indicate a growing interest in tankless type heaters. We are pleased to invite Paul Rohrs, national trainer at Lochinvar, to the webinar series for a first-ever appearance to help you make a smart choice for your customer's hot water needs. Come on in... the water's warm!

You'll learn:

  • What has changed regarding safety requirements on tank-style heaters?
  • When is an electric hot water heater a viable option?
  • Heat pump style: what's that all about?
  • I've heard most of Europe and the rest of the world heats with tankless: T or F?
  • What are the trade-offs of each style?
  • Cost-wise tank vs. tankless is almost a wash these days: T or F?
  • Give me an honest, "no sales" comparison based on data and experiences.
  • When does a combi heater make sense to consider?
