Baseboard Calculation

Axeman:

A "rule of thumb" calculation would take the square footage of each room, multiply 45 to get the heat needed in btu, & divide by 550, the heat output of each foot of standard baseboard.

Venturi Loop

Noel:

Don't worry, you can make it work; first make sure you put the venturi valve in correctly, it's very easy to put them in backwards; most of them have "supply" , "return" or an arrow...

Floor Heat Leaking

rma1998

Air Problem

Heating Problem

I'm not completely convinced yet that you actually have an air problem; you describe the sound you hear as a "ping/drip"; an air problem in the supply/return piping sounds a lot more like...

Front & Lower Radiators not heating

Nynetek:

This is a classic example of a FLOW problem & not an AIR problem; a water temp of 215-225 is WAY too high for a HW system; when you heat the water that high it becomes VERY LIGHT,...
