Plumbing / Re: Heat exchanger plumbing question.

are you saying that you have a oil fired boiler that you use for heat and you bought a wood boiler and want to add it to your system as a primary source of heat and oil boiler for backup? if so your oil boiler is going to be a closed loop system that operates under pressure and the wood boiler may not. you could tee into your supply and returns on the oil boiler. you will however need to install valves to isolate the oil boiler from the wood boiler and valves to isolate the wood boiler from the oil boiler. hope this helps

I have the exact same pump installed on my system. plenty of water. im pushing through a plate hx first and then to the house hx. that pump gives plenty of room for "engineering anomalies" for reasonable installations

If your nifty with a torch and hard solder and have plenty of time you can make one any size you want. just slice the coil into the size slab you want and remove an inch or so of the aluminum fins to expose the copper tubes. hold a piece of 3/4 copper against the ends to transfer the locations of the stubs drill all the little holes and solder the two together. repeat for the other side and you have a homemade water coil.  but if it were me i would shop in the range of a 150k-200k sized coil or find some old car radiators experiment and let us know how it turns out. i always wanted to know myself about that

I bought one of those store built pool heaters before I got a wood boiler. propane model.  Hooked it up and when I fired it up almost seems like I did not make it ten steps away from it and it had just about sucked the bottom out of the tank.  Man those things like the gas.  Just glad I only wasted $400 on it.  It worked fine but the only problem was I dont have a propane well in the back yard.  I have wasted a lot more money on a whole lot less in the past im only glad the wife got to enjoy it and has forgotten about it.  RIP pool heater

Plumbing / Re: Duct Heater (would this work?)

« on: January 14, 2012, 08:31:47 PM »

Yes a air gap or a summer bypass will work just the same.  My summer bypasses are simply a slide gate built into the duct that is removable for the summer. Sounds like you had a good installer ridgekid.

Brazetek I think its called will custom build them for you if they dont already make that size.  More importantly find out what the static pressure drop across the coil.  Most residential duct systems are already pushing .25 in/wc.  If you install a coil that has say .35 static you mite get out of range on air flow for your ac to work properly.  You could get around that by installing a summer bypass damper to bypass part of the air around the coil.  Just my opinion anyway
