5,000 sf of baseboard on a 1\" injection?

[Deleted User]

Load in btuH, design fluid temp at point of use at design conditions, availability of supply temperatures from heat source, length of run from source to point of distribution, is mini tube insulatable, is mini tube going to be within a heated space?

Rough rule of thumb, if your friends 5K square foot castle is needing 30 btu/sq ft/hr (a LOT) then your base load would be 150,000 btuH. If the water coming back from the zones is say 140 degrees, and the supply is 180 degrees (40 degree delta Tea) then, yes, 1" will carry it, but you'd better make sure your heat source doesn't mind seeing 140 degree EWT....

Gallons times pounds time delta T = btuH delivered, but theres more than meets the eye :-)

can i heat this? like this?

i have a friend that needs to heat a 5,000 sf area (baseboard and two radiant panels)
the boilers will be 100 feet away
i told him i would check and see if we could run 1" pex and inject to a remote manifold ( i ran the calcs and i think i did them correct...10GPM..?..)
soooo....am i right?way wrong? need to offer more info?
PLEASE HELP ME WALL !

Mark is Right (That is a headline??)

Especially the part about the radiators being tolerant of what might be lower temperatures. Radiant panels properly sized will be more forgiving than baseboard/convective heating.

Injection can deliver a surprising amount of heat.

Just like Dominos can deliver a surprising number of pizzas.

Just a tad cooler, that's all.
