Ok, I thought I knew what I was doing.. BUT In researching indirect heaters, I found mostly two types, steel tanks with a lining and stainless steel. I figured the stainless steel would be best since they required no anode rod or anything. Im feeding it with PH neutral Softened water that seems very clear.
My heating Company says I should use a Vaughn with a stone lining but I cant find any information on reliability etc. They differ in a number of ways. They have a totally different plumbing setup it seems and a smaller heat exchanger. They also only come with a seven year waranty as standard rather than lifeltime. They sell a extended lifetime warranty for 100.00. These things are not cheap to have installed and I would hate to buy something destined to explode all over the floor in five years.
Does anyone have any experiewnce with them good / bad or otherwise. Perhaps Im making too much out of it.
