Heat of extraction formula
What formula do you use? Is delta t of water x gpm x 500 for water (pump and dump) aka open loop correct ? If so how do you get your gpm? Is the flow restrictor size good enough or ?.

For pump and dump I use a 5 gallon bucket and a stopwatch.

measure entering water pressure before it enters the unit (PT port) and pressure exiting the unit (PT port). Every manufacturer ive seen has a chart in the product specs that will show you the gpm at a measured pressure drop at a certain temperature. Pretty easy when you see the chart ....make sure its for the right size unit. That same chart will give you your heat of rejection/ extraction
