Hundreds of gallons for summer use? Hardly. I have personal experience with this issue, besides working for a manufacturer of quality boilers. For almost 30 years, I used a medium sized, cast iron, boiler for just one purpose....domestic hot water for a family of five. We started heating with wood immediately in 1977 and never used the boiler for the baseboard. Over a 30 year span, we used approximately 250 gallons per year, each and every year. When oil went up to the high one dollar amount, I called PPL and tried to determine if it would be cheaper to go with electric hot water.....it wasn't. An indirect hot water tank loses 1/2 degree per hour standby, compared to maybe 5 degrees in a boiler, so they are a good way to go. There are two methods of construction on indirects. The one I would use would be the Ergomax. Compare that one with the others that run boiler water through the copper coil.

"You can't blame them since the probability of having a leak is high. They don't want to deal with the call backs." What do you mean the probability of having a leak is high? If there were to change the inside coil and leave the old condenser, the old condenser will likely start to leak? I have the home warranty paying for the coil, but I would be paying for the condenser (if I replace). Frankly, if replacing the coil led to the old condenser leaking too, that would be good for me since I could get that replaced under home warranty too. Is that a common occurrence? Thanks again for the info. Also, any idea if the $950 to replace the coil is fair market value for a job like that? (that's what they offered me as a cash out from the home warranty company).

First has made the same products for many years. You can probably buy a new pan from them. If they won't sell to you, make sure they have a pan available, then find a distributor willing to sell to you. Many local suppliers have bought from first over the years. First may have discontinued the product, but the replacement product may be the same size. You need to ask them if this happens. Pans can be made by a local sheetmetal shop. In the past they would have cost less than $50. I have not had the need for a replacement pan in more than 10 years, so prices are not current. Depending on where you live in Dallas, the prices for service can vary. Park Cities pay more for service. Frisco pays more. The company makes indoor coils and air handlers for York. It is a large company that has proved helpfull to me in the past. Before you call them know the model of the coil if possible, and the dimmensions of the pan. I saw a repair kit at a local supply store. I have used epoxy on evaporative coolers in the past, but never on an AC pan. The repairs I made were on the roof. Leaks would only reduce efficiency of the cooler. I recently saw a repair made on a tub with exoxy. It looks strong 2 months later. I would not normally consider this type of repair, but the customer was willing. I have gone back several times to fix problems at that house.

mallens There is a box on top of the furnace. The evaporator coil is in this box. There is a hole in the box that the copper pipe connects to. The pipe is help in place by a rubber seal thingy. (dont know what it is called) The rubber seal came loose from the box with the where the coil is housed and it is just hanging around the copper pipe now. Since it is not inserted in the hole, water is dripping out of the hole. very slowly.
