Finally getting around to the boiler install on the new house. I will be buying a boiler and indirect tank this week and hopefully working on the inside of the house with the heat on by Christmas...hopefully. I'm looking at a 110K BTU boiler and it will be propane fired supporting a slab zone, warmboard radiant subfloor and indirect tank. Will be using a 3-way mixing valve and have an idea for starting water temp from the Uponor ADS software. Will most likely be doing the install myself as I live in the absolute middle of nowhere and I haven't found anyone that is interested in traveling for a decent price. I have been using Uponor stuff for tubing and manifolds and am happy with my supplier of these, probably using Grundfos circs because I like that brand in other pumps we buy. Not sure on relays/controls but i figure I can't go wrong with either of these brands' stuff there either. Is there a real difference in ease of setup and installation and longevity and quality of components between these two boilers? I have been told that the TT does a better job of keeping clean and burns cleaner longer on propane than some. I also like the idea of a stainless heat exchanger and integrated indirect loop. And which style of indirect tank is the best? Thanks!
