Harvia specifies these for the Spirit, where the stones sit in open view and the look of the stone bed is part of the heater.\u003c\/p\u003e\u003cp\u003eOne box holds 33 lbs of rounded stone graded 2 to 4 in (5 to 10 cm). Your heater page tells you how many boxes that heater takes. Shipping is charged per box at checkout, including when the stones are ordered with a heater. Order the full amount: Harvia sets a minimum stone charge for every heater, and a half-filled stone space lets the elements radiate straight out at the room instead of into the stone.\u003c\/p\u003e\u003cp\u003eRinse the stones before the first heat. Stack them loosely so air can pass between them, never pack them tight, and restack once a year.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFits:\u003c\/strong\u003e Spirit SP60E, Spirit SP80E and Spirit SP90E.
