I've spent a lot of time on here searching and reading and have learned a lot. At least enough to make some decisions and formulate a plan - and have a bunch of questions!
So I have a Taylor 450 thats about 90' from the house. I'll slide a heat exchanger into my existing air handler. I plan to keep my forced air propane as back up. A good old simple round Honewell thermostat contols the propane furnace right now. As I start to finalize things, here are my questions:
From what I've learned from here, I can install an aquastat at the OWB that will kick on the propane if the fire goes out and still utilize only one home thermostat. Question #1: what size/type wire needs to go from the aquastat to the thermostat (and which aquastat do you recommend)? I have the trench open and will start laying line as weather allows.
I think I want the pump to only run when the house thermostat calls for heat (right?). I plan to enlist the aid of a knowledgable HVAC person but want to know what I'm talking about. Question #2: Is the pump controlled by the house thermostat too then? Anyone thats done this have a basic schematic to accoplish this?
I'm tapping into my domestic hot water. From this site I realized I'll need a mixing valve for safety. Question #3: Is it installed on the outlet side of my electric hot water tank (which is feed by the OWB)? And I assume it has a cold water port for the mixing part, is the thing adjustable?
Sorry for all the questions and thanks in advance for any help.
