Query: This Titan is amazing

I am on my 7th rental property and my 7th Titan unit and I love them. I have been using Titan for over 6 years now and I would never go back to a tank. The unit is reliable and best of all they are made in the good old U.S.A. The tenants love the space saving and specially the energy savings. I would recommend these units to anyone who is looking to save and purchase great American made product.
