Troubleshooting hydronic systems can be challenging, as the pipes are hidden behind walls. Your imagination has to help you “see” the routing of the piping. 

Have you ever had one of those times when you’re trying to figure out some problem and then suddenly the solution comes to you as if by magic? 

The measure of a heat pump’s heating performance is called coefficient of performance (COP). It’s the ratio of useful heat output divided by required energy input, where both the output and input are expressed in the same physical units.

I was wondering about boiler chemicals and how many contractors (if any) were using them on brand-new systems. Do we need them? 

Most of the modern hydronics technology used in North America for residential and light commercial buildings is for heating. 

The heating output and coefficient of performance (COP) of any hydronic heat pump is very dependent on the water temperature leaving the heat pump’s condenser.
