Sizing the Pump and Plumbing for a Solar Water or Space Heating System

I go through a fairly simple procedure that will allow you to pick the right size pump and the right diameter plumbing for your solar water or space heating system.

I use my Solar Shed space heating system as an example, and go through sizing it in detail. 

The Solar Shed is a fairly large 240 sqft of collectors system, but the procedure can be used for any size system.

The procedure covers:
  1. Estimating the flow rate that a set of collectors will need
  2. Estimating the pressure drop in the pipes due to pipe friction
  3. Using pump curves to pick the right size pump for the system
 All the details on picking pump n' pipes for solar heating ...
