6.7.9 Multiple heat sources with buffer tank
Hydronic heat pump; system fluid circulates outdoors so typically requires glycol
treatment.
High Efficiency Hydronic Gas Boiler or Electric boiler staged (by IBC Sky 35
controller) to supplement heat pump below system balance point.
Check Valves
Closely-spaced tees: max. four pipe diameters apart, min. eight pipe diameters
straight piping upstream and four downstream
Buffer tank. Buffer tank needs vacuum breaker for cooling mode.
