A couple of more questions, Jpen :)

Why are you running the boilers in parallel? What advantage does that give your system? I assume you aren't using the oil gun on the old boiler? Did having both boilers affect your decision on the size of your LL purchase? And finally, what did you have to do differently from a control standpoint to get them both operational? It looks like your sending the hot water from the LL to the old boiler and using your existing recirculation pump (not the supplied unit from LL) in order to drive the system, but I really can't tell from the pics.

I'm actually running the boilers in a series hybrid setup with coal biler being the slave and the oil boiler being the primary. This allows me to activate the oil boiler at the flip of a switch if necessary. I pump water 24/7 between the 2 boilers and the stay with a dgree or two of one another. I had the oil boiler and it was only aboput 7 years old so I decided to keep it as a backup as a I like redundant systems to allow for part failures in the middle of the night when they always happen. I have a taco sr503 zone/ circulator controller wired independent of the boilers to control the zone circulators. It has a set of dry contacts that you wire to the TT terminal of the both boilers triple aquastat's which start the boiler whic is operating when a demand for heat occurs.

It sounds like you have a lot of radiation for the square footage you are heating. That is the way to go, and it definitely allows you to use lower boiler temperatures. On cold/windy days, my radiation has a hard time keeping up with the boiler at 160 degrees...then again I do live on a small hill with about 500 acres of wind-tunnel creating fields to the West. You can say that conditions are "extreme" at times.

That is a big "If". You would defiantly have to have it piped with a bypass, or in a primary/secondary fashion. Either way, it would probably run a long time to get the system up to temperature. As long as the heat loss of the house is less than the boiler's net output it would catch up eventually, but you probably wouldn't want to use a set-back thermostat.

Yea I know what you mean by living on a hill and I am in a Valley know all about high winds in the middle of winter cold
temps and snow is not scars around here either
