Harvia Spirit SP80E: an 8 kW curved wall heater with the stones on show, for saunas up to 431 cubic feet
The Harvia Spirit SP80E is an 8 kW electric sauna heater for saunas from 177 to 431 cubic feet, the middle size in the Spirit line. Its curved body has stacked stainless steel hoops that leave the rounded stones in full view, with a black panel down the front. It is wall mounted on the included bracket rather than standing on the floor. It is 15 inches wide, 13 inches deep, and 29.5 inches tall and weighs 140 pounds with its 110 pounds of stones in place. It heats the room quickly.
The box holds the heater, the wall bracket, the top safety device that guards the stones, and the manual. It needs a Harvia Xenio wall control to run, and you add that on the page. Sauna stones are sold separately, so add the 4 boxes it needs on the page. A black birch safety rail and a bucket and ladle set are optional. Need more heat? The Harvia Spirit SP90E sauna heater reaches 494 cubic feet. The Harvia Spirit SP80E ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
FAQ
Does the Spirit SP80E come with a control unit?
The Spirit runs on a separate Harvia Xenio control — it is compatible with the Harvia Xenio Wall-Mounted Control and the Xenio Wi-Fi Package. You do not need to source one elsewhere: the compatible Xenio Wi-Fi digital control is offered right on this page under Sauna Heater Controls, so add it to your order and everything arrives together.
What size sauna room will an 8kW heater like this heat?
It is rated for sauna rooms from 177 to 431 adjusted cubic feet, and Harvia notes this premium electric heater heats quickly to your preferred temperature. Since those figures are adjusted cubic feet, check the installation manual linked on this page when working out your room’s effective volume.
Can I start this heater remotely?
Yes — it is compatible with the Xenio Wi-Fi Package, and its integrated safety features are designed to make remote starting safe: the heater cannot be turned on if items are placed on top of it, and dual safety sensors monitor both the heater and the temperature of the sauna space to prevent overheating.
How many sauna stones does it need, and are they included?
It requires a minimum of 110 lbs of stones — four boxes of Harvia’s rounded olivine stones, which also accentuate the heater’s curved design. Select the four boxes under Required Stones on this page so they ship with your order, and consider an extra box, since natural stones vary in shape and size.
What comes in the box, and how is it mounted?
The package includes the 8kW Spirit heater, the safety device that sits on top of the heater, a wall-mounting bracket, the installation and operation manual, and a 2-year consumer-use warranty. The bracket is your mounting hardware — this is a wall-mounted heater measuring 15 inches wide, 13.1 inches deep, and 29.5 inches tall.
What are the electrical requirements?
The specification table lists 240V single-phase power. As with any hard-wired sauna heater, installation should be completed by a licensed electrician following the installation manual on this page and your local electrical codes, which determine the proper circuit, breaker, and wiring for the unit.
What sets the Spirit series apart from other Harvia heaters?
The Spirit is Harvia’s elegantly curved design — a premium, Finnish-made electric heater whose natural, organic shape is accentuated by rounded sauna stones, with integrated safety functions built in. A matching black safety railing for Spirit heaters can be added to your order on this page, and you can compare models across the Harvia Spirit collection.
