After reading Dan Holohan's books Classic Hydronics and Pumping away I was inspired to upgrade my boiler piping. I couldn't find a before picture (I had one on my old phone) but I corrected the position of all the hydronic components. I added the supervent microbubble resorber, Taco Viridian VT2218 ECM circulator and tees for the addition of another zone and an indirect tank. I still have to get zone valves and finish insulation of the pipes. Also added some 8 way boiler treatment, now I have violet colored boiler water!
Currently the boiler is a two pipe reverse return Venturi tee system. Running my AFG on a .65 80B nozzle. 425 degree stack temp, 6% O2, zero CO, 11.20% CO2 and 84.9% efficiency. I love the capabilities of the VT2218, currently set on setpoint heat mode with boiler protection on. I also have a Honeywell outdoor reset module, design temperature 10 degrees
Does anyone have any suggestions for further improvements to my set-up?
