To Whom It May Concern:
We have been using the Vaportec designed tube (coil) in shell heat exchanger for over 3 years, and to date have experienced no warranty failures. We offer a 5 year warranty and so have been very pleased with the results thus far.
The Vaportec heat exchanger carries ETL certification and is CE compliant as well.
The Spirex twisted titanium gave us a significant performance improvement over our previous tube in shell heat exchanger design, and that coupled with the lack of warranty or field failures has made this a superior heat exchanger in the US Pool Heat Pump market.
