"if you want to be happy with your system and to run as best as it can get as much info as you can so your not doing it twice."
AMEN! Thats the best and only way to put it!!!! I thought I had enough information. I read about all the boilers and their designs, materials manufactured with, warranties, stainless vs. plate steel, etc. But there was more I didn't look into. Look into the lines underground, the material that is used to insulate the lines, the heat exchanger-water to water or water to air, pumps needed to get the hot water to the house, etc.
I wish I would have had all the information that I needed before I dropped the large sum of cash on a system that is not working nearly up to the speed that it should. I am going to have to dig up my lines and replace them along with re-wiring the system inside the house. All adding up to spending double on something that I should have only paid for once.
ghitch75- I have zone pumps(taco 007) on each zone in my house except the basement radiant floor(taco 0011)which is another fiasco in and of itself. Each zone kicks on when the thermostat in the room(zone) calls for heat. My concern is that the primary loop pump runs constantly when there is no call for heat in any of the zones, thus running down the temp of the primary loop due to the water constantly flowing thru 10-12' of uninsulated pipe, causing my propane to kick on. It is running as I type this and nothing has called for heat all day.
Thanks
