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. 

A happy sow is a better sow. If you didn’t know that, don’t worry: The people who need to know it do. 

Whenever a hydronic system is divided into several zones, it’s worth considering a buffer tank between the heat source and distribution system.
