Saunalogia Harvia Spirit Review
The Harvia Spirit was rigorously tested and reviewed by Lassi Liikkanen of Saunalogia. Lassi wrote the most trusted book on Finnish Sauna Design (buy it here), and takes a scientific approach to sauna testing.
Here’s our summary of his findings:
The Harvia Spirit electric sauna heater is a unique blend of style and efficiency, perfect for those who appreciate an understated design that doesn’t overpower the sauna interior. Its compact form factor, similar to a corner heater, allows it to fit in smaller spaces.
The Harvia Spirit can also sit low to the floor, allowing for a better sauna design with lower benches.
The Spirit heats up quickly, often achieving optimal temperatures in less than an hour, demonstrating significant energy efficiency. One standout feature is its strong initial löyly (sauna steam), which mellows out on subsequent water pours, offering a unique sauna experience.
However, it has room for improvement in achieving even heating on its sides. Its control panel could be more user-friendly, and stone installation may be tricky.
A remarkable attribute is its lower energy consumption than its 9 kW counterpart. While the Spirit’s upfront cost is relatively low, its rounded stones are pricier than conventional ones, adding to its lifecycle cost.
Despite being pricier than the most affordable options, the Spirit’s performance and design qualities make it attractive.
Compared to other heaters in Harvia’s range, the Spirit holds more stones, is easier to place, and offers superior löyly potential.
Harvia Spirit’s design philosophy pivots on an understated presence, focusing on being a sleek, asymmetrical heater that blends effortlessly into the sauna environment. It’s intended to be more of a wall ornament that adds sophistication and style without dominating the space.
On the other hand, the HUUM DROP is known for its bold and unique aesthetic. Its drop-shaped design has been a standout factor in the industry, winning it a loyal fanbase. Nevertheless, the latest online polls from Sauna Marketplace indicate a slight preference for the Spirit’s more subtle design.
Performance and Durability
Harvia Spirit’s innovation lies in its metal duct structure, which protects the resistors while efficiently conducting heat. This design ensures the stones aren’t in constant contact with the resistors, improving overall performance and longevity. The Spirit also excels in its heating capabilities, offering a rapid heat-up time while accommodating many stones.
The HUUM DROP has had issues with heating elements failing prematurely. Despite this setback, HUUM has shown resilience and a commitment to improvement by developing a frame that aims to hold the elements securely in place, potentially mitigating the issue.
Harvia Spirit offers a modern, globally appealing design complemented by remote operation via a mobile app, providing users with an excellent blend of traditional sauna experience and modern convenience. The initial setup and stone installation may require patience and technical understanding, but the resulting experience is worth it.
The HUUM DROP, despite its aesthetic appeal and impressive performance, has had a mixed reception regarding its user experience. The reported premature failure of heating elements has caused some dissatisfaction among users. However, it’s important to note that HUUM’s forthcoming frame could potentially address this issue.
Harvia Spirit while priced slightly higher than the market average, provides a valuable blend of design, functionality, and performance. The Spirit’s aesthetics, heating efficiency, and user-friendly features such as remote operation, offer good value for the investment.
The HUUM DROP, with its unique design and performance, also holds a competitive position in the market. Yet, its issues with heating element durability have impacted its overall value proposition. The release of the new frame could boost its standing.
While both heaters have their unique strengths and weaknesses, Harvia’s Spirit emerges as a promising contender in the market, especially in terms of its design, performance, and usability. Its subtle aesthetic appeal and efficient heating capabilities make it a versatile choice for many sauna enthusiasts. Despite this, the HUUM DROP with its distinctive design and forthcoming enhancements, can’t be discounted and remains a strong competitor. The choice between the two often comes down to personal preference, with design aesthetics and user experience playing significant roles.
Addressing the Heating Element Issues of the HUUM DROP
While the HUUM DROP has been plagued with premature heating element failures, they are set to release a new frame to address this issue; the Spirit, in contrast, has been designed to preempt such concerns with its unique heat-conducting metal duct. Thus, the Spirit not only learns from the past issues of its competitors but innovates to avoid similar pitfalls.
