Harvia Stainless Steel Water Tank Heater: Hot Water From Your Sauna Stove — No Extra Fuel Cost
The Harvia Stainless Steel Water Tank Heater is Harvia’s Stove-mounted water tank heater for wood-burning sauna installs. It captures otherwise-wasted chimney or stove heat and turns it into usable hot water during the sauna session — water for the shower-off after, for pouring on the stones, or for the rinse-down at the end.
This is standard practice in traditional Finnish sauna. Run the stove, get hot water for free. In a well-insulated sauna room the water heater is producing hot water the entire session with no additional wood burn.
Why Buy From RecovAthlete
We’re an authorized Harvia dealer. Water heaters are specifically sized to the stove family and flue geometry. Mixing a non-Harvia water heater onto a Harvia flue is a guaranteed install headache.
Call 866-861-6317 with your stove model and flue configuration — we’ll confirm the right water heater model before your order ships.
“In a properly-designed sauna, hot water for the post-session rinse shouldn’t cost extra fuel. The stove is already running — capture the flue or body heat and use it.”
Best For
- Owners of compatible Harvia wood-burning stoves wanting integrated hot water from stove body heat
- Cabin and off-grid sauna installs where water heating would otherwise need a separate energy source
- Classic Finnish sauna builds where the water-heater-on-flue is part of the tradition
- Replacement of an older, corroded water tank on an existing Harvia install
Not Ideal For
- Electric sauna heater installs — no chimney or flue heat to capture
- Very small sauna rooms where a water tank is overkill
- Installs without plumbing infrastructure for water inlet and hot water draw
Who Buys This
- Homeowners building a classic Finnish-style wood-fired sauna
- Cabin and lake-house owners wanting integrated hot water without a separate heater
- Sauna builders specifying the complete traditional setup at quote stage
- Owners replacing a corroded or damaged existing water tank
What You’re Actually Getting
- Stove-mounted — mounts to the stove body — captures otherwise-wasted heat from the stove or flue and transfers it to the water tank
- Stainless construction — resists corrosion from the constant water-plus-heat environment
- Factory-matched to Harvia stoves — sized and positioned for Harvia’s flue standard and stove outlet geometry
- Free hot water during sessions — the stove is already running — the water heating has no additional fuel cost
- Traditional Finnish sauna spec — part of the classic wood-burning sauna configuration that Harvia has refined over decades
IMPORTANT: Compatibility
Mounts directly to the stove body, using the stove’s radiant and conductive heat to warm the tank. Compatible with Harvia wood-burning stoves that have the factory-specified mounting geometry.
Call 866-861-6317 to confirm your stove supports stove-body mount.

Shipping & Delivery

The Investment Frame
A wood-burning sauna that produces free hot water during the session is a fuel-efficient install. Over a cabin’s typical 20–30 year life, the cumulative energy savings on hot water alone add up to more than the water heater cost.
Frequently Asked Questions
Does this work with electric sauna heaters?
No. Water heaters capture heat from the wood stove body or chimney flue. Electric heaters don’t produce a flue heat source to capture.
How much hot water can it produce?
Varies by stove size and session length. A standard Harvia wood stove running for a 2-hour session typically produces enough hot water for 2–4 rinse-downs. Exact output is in the Harvia install manual.
Does installation require a plumber?
Yes. Water inlet and hot water draw require standard plumbing connections. Your sauna builder or plumber handles this as part of the install.
Does the water heater affect stove performance?
No measurable effect. The water heater captures heat that would otherwise exit the chimney or radiate unused — it’s efficiency recovery, not heat theft.
Stove-mounted vs pipe-mounted — which to choose?
Pipe-mounted (WP250LD) uses chimney flue heat and is typically more space-efficient. Stove-mounted (WP220ST) uses stove body heat and may warm water faster. Choice depends on stove geometry and install layout — call us for help.
