Summary
In this two-part interview, Moe Hirsch goes deep and wide on buffer tanks and strategies for "parking" BTUs in hydronic systems.
When we use boilers, we want to use a heat sink to "park" BTUs in a buffer tank so that we can temporarily store extra heat and avoid short cycling through load matching. However, few boilers have an actual buffer tank; many systems have a means of creating a buffer, though. Buffer tanks are good for parking BTUs in systems with zones and microzones that require varied heating needs. The amount of BTUs you store depends on the temperature difference between the beginning and end of the tank and the water quantity.
Moe and Bryan also discuss:
- Pressure tanks
- Variable frequency drives
- Getting extra BTUs
- Snowmelt systems and Combi-boilers
- Two-pipe and four-pipe configurations
- Creating and positioning buffer tanks
- Hydraulic and air separation
- Reverse indirect water heaters
- Parking BTUs in concrete
- Dirt and magnetic separation
