Hydronic Heat Pump

Hydronic Heat Pump Tasks

• Bleed radiators or in-floor loops

  Each fall, open each radiator's bleed valve until water flows steadily, then close it; bleed in-floor loop systems at the manifold.

  Once a year, in fall
• Check hydronic system water pressure

  Each fall, check the pressure gauge on the unit or buffer tank and use the fill valve to top up if the reading falls below the labeled range.

  Once a year, in fall
• Clean hydronic heat pump outdoor unit

  Each spring, shut off power at the disconnect, remove the top grille, spray the fins from inside out with a garden hose, and clear debris from the base.

  Once a year, in spring
• Clear snow and ice from hydronic heat pump outdoor unit

  After each snowfall, clear drifts by hand and knock loose ice off the top and sides of the outdoor unit; leave light ice for the defrost cycle.

  Once a year, in winter
• Schedule hydronic heat pump tune-up

  Book a licensed HVAC tech experienced with hydronic systems each fall to inspect refrigerant charge, buffer tank, circulator pump, and water loop pressure.
