We had the heat recovery unit installed when we built our home 10 years ago. We live in south Florida and our “24/7” A/C season runs April thru October. During that time I literally turn off the breaker to the hot water heater. The HRU provides what seems like unlimited and extremely hot water. No doubt the unit has paid for itself many times over. I would never consider not having one. The HRU has been trouble and maintenance free. We love it. Thanks for a great product.
