TK, The fan speed was reset to 2800 about two weeks ago. I have seen a marked improvement on the cycling. I have not adjusted the mod rate yet, still thinking about that. The min fan speed is set to 1300 (factory), when the gas valve modulates down it drops to 46% (min mod). I was wondering...

Adding thermal mass Dana, When the P/S piping was installed we took into consideration adding an indirect heater in the future. The take-offs are there w/ ball valves ( I pulled the handles off). If I am adding 15 gallon electric tank (unpowered), should it be installed just after the two...

Fin Tube Length Dana, I may have mis spoke ....... the 300' is the total run of copper on both zones. The emitters for each zone, (zone 1 = 60', zone 2 = 65') total 125 '. Is that what you understand ?

TK, I plotted my way thur a heat loss calc (3 hours for somebody that does not know what they are doing) and came up w/ 70,000 loss. The boiler that was installed is the Alpine 150. From what I read, it has a min mod ouput of 28-30 K with a max of 120 K. I have two loops split evenly.

Dana, I would be interested in looking at a piping diagram for the electric water tank. If a buffer tank sits across the loops, (2) supply outputs and (2) return inputs, how does a standard hot water tank work ? I'm thinking the electric hot water tank has (3) available ports (supply, output...

TK, I was not aware that standard buffer tanks need/use an aquastat. I thought that buffer tanks are piped using the four ports and the cavity served as a storage facility. I'm guessing the boiler circ pulls from the tank to maintain flow for the boiler while the zone circs pull from the tank...

Adding a buffer tank I have lowered the fan speed and have seen a marked improvement. My next thoughts are w/ a buffer tank. The loop is piped w/ P/S and the tees are spaced per the installation manual. From what I have seen, it looks like a buffer tank would be installed "inside" that...

TK, the plan is to install a SuperStor Indirect. The take offs w/ ball valves were installed on the headers.I think he said that the indirect load would be larger than the fin tube. We have a 3 bedroom house 4 people, two teenage age girls ! We do not have the tank yet. At this point I have...

Alpine questions Dana, Your posts are informative and helpful thanks. I find myself in the same position. My Alpine 150 might be too big but I'm not sure. I am 20 minutes north on 190 so you know the climate. If it is oversized I am thinking it is not by much, maybe I should have 105 ??? The...
