The run from the boiler to the coil is only about 6', actually there is a total of only about 15' of pipe connecting the boiler to the coil (well, where it will be). I think the Taco 007 will do the job and I'm going to try it because it came with the boiler but I actually think it will probably circulate without a pump because the inlet to the coil will be about 6" lower than the top of the boiler so it should flow naturally. I know from an engineering standpoint there is an ideal way to do things, from a penny-pinching standpoint there are alternative ways that will work. Back in the bad old days we had a wood stove in the living room. 95 degrees in the living room to keep the spiders warm and 50 degrees everywhere else
In any event I'm way ahead of my coal budget where it looks like I might break even or even save money this year vs. 5 or more years if I had a plumbing contractor come in and do everything. That includes all the equipment and fuel costs and the cost of coal vs. just using propane. I'll be sure to let you guys know how it works (or doesn't work
) when it's cold out. I have a need for the ashes also so they will come in handy paving a path to my chicken coop.
