Another quick update: The system is up and running, and working well for the past 5 weeks or so. We've had one unusually cold period (28F for a few hours one night), at which the system had a little...

Hi all,
I haven't had much time to collect information and post it here, but I haven't been completely idle. The manifold is hooked up, the old furnace removed, and I've had a bit of a hard time...

OK, thanks! Going for a different pump than I originally intended, then. The zone valves are built into the manifold, so I don't know what type they are - but it is a closed loop system. I'm still...

I see what you're saying - clearly, any system will only use as much heat as it needs based on turning on or off the circulator; what I'm getting at with the calculations is to figure out how much...

Going a little further with this: say we more than double the heat loss for our coldest nights, to 4000BTU/h.
I've got 980 ft^2 of heated floor surface, that means I'll have to put at the most 4...
