The Harvia Linear 28 package pairs a 22 kW wood-burning sauna stove with a Harvia WHP1500 steel chimney, WL110 floor bedding and 3 boxes of stones. Harvia rates it for saunas of 353 to 918 cu ft.
The Linear 28 is the tall member of Harvia's Linear range: a sculptural graphite black body with a cast-iron glass door that can be rehung either way. Its fire chamber and air channels are built for quick warm-up and controlled burning.

Harvia rates it for 10 to 26 m³. Bare surfaces raise the need: Harvia's own example puts a 10 m³ room with a glass door at about 12 m³, and a 10 m³ log room at about 15 m³.
No. It loads inside the sauna. For firing from the next room, look at Harvia's through-wall Duo models, such as the Legend 300 Duo.
Yes. Harvia's manual covers a masonry flue through the back or top opening. The top route needs a 45° or 90° angled smoke pipe. This package ships the WHP1500 steel chimney for the top opening.
The WHP1500 kit gives about 7.75 ft of height before the rain cap. For a taller roof, add insulated WHP1000 or WHP500 sections, or extra smoke pipe below them. Both are on Optional Upgrades.
Harvia's maximum for the stove body is 50 kg (110 lb). The package's 3 boxes (132 lb) cover that with part of a box spare. Pile them loosely so air moves between the stones.
Dry firewood only. Use logs 3.1 to 5.9 in (8 to 15 cm) across and no longer than 15.4 in (39 cm). Never burn chipboard, pellets, painted wood, plastics, garden waste or liquid fuel.
The coating smokes as it bakes on. Do that first burn outside if you can, with no stones in the stove. Load the stones only once it has cooled.
Close every opening on the stove and flue to starve the fire of air, and call emergency services. Never use water. A sweep checks the system before you light it again.
Buying for yourself, spread the cost through Affirm at checkout. Buying for a gym, clinic, spa, or studio, apply with one of four business lenders and put the whole room on a single application.
RecovAthlete has no control over any financing decision. Approval is based on your creditworthiness and is solely the lender's decision.
Affirm at checkout. Rates run 0% to 36% APR based on your credit profile. Soft check to prequalify, so no impact on your score. No prepayment penalty.
Brickhouse Capital, Reliant Capital, Acorn Finance, or KWIPPED. Apply with two of the four and compare. Financed equipment can qualify for a Section 179 deduction. Confirm with your accountant.
Every page below has real prices, real monthly payment examples, and the lender comparison for that category. Pick the one you are buying.
Most business buyers are not buying one machine. They are building a room. Sauna, cold plunge, red light, vibration, hyperbaric, cryotherapy, and halotherapy all finance on the same paper through the same four lenders, and RecovAthlete quotes every category on one purchase order.
That means one freight schedule, one install window, and one financing application instead of six. It also gets you a better rate, because a bigger number on one application beats six small ones with six hard inquiries.
See commercial recovery equipment financing, or call 866-861-6317 and we will price the room.
| Lender | Type | Amount | Speed | Best for |
|---|---|---|---|---|
| Affirm | Consumer, at checkout | Order total | Seconds | Personal purchases. 0% to 36% APR based on credit. Soft check to prequalify. |
| Brickhouse Capital | Direct equipment lender | Up to $250K on a one-page application, $1M+ with financials | ~24 hours | A full room or a full floor. Credit decisions made in-house. Tied to the business, not your personal credit report. |
| Reliant Capital | Lender and broker | Up to $500K application-only, $5M with financials | 2 to 4 hours | Medical, aesthetic, and wellness. Deferred payment options. New or used equipment. |
| Acorn Finance | Lending marketplace | $1,000 to $100,000 | 60 seconds to prequalify | Comparing offers. One application goes to 30 or more lenders with no impact to your score. |
| KWIPPED (APPROVE) | Lender marketplace | Minimum $1,500 equipment value | 60-second application | Larger commercial orders. Lenders compete, which usually returns the best APR. Businesses only. |
Apply with two of the four and compare. It costs nothing and the spread between offers is often significant.

Pay in 4 splits the purchase into four interest-free payments charged every two weeks. Monthly installments spread the cost over a longer term, with rates from 0% to 36% APR depending on your credit profile. You see the exact terms before you agree to anything. No origination fees, no prepayment penalty, no late fees.
Prequalification does not. Affirm and Acorn Finance both run a soft check to show you offers, which has no impact on your score. Proceeding with a monthly installment plan or a business loan may involve a hard inquiry. That is why it pays to prequalify with more than one lender first and only proceed with the best offer.
Yes, and for most business buyers it is the better route. Brickhouse funds up to $250,000 on a one-page application with no financial statements. Reliant approves in 2 to 4 hours. Business financing is usually tied to the business rather than your personal credit report, and financed equipment can qualify for a Section 179 deduction. Confirm the tax position with your accountant.
No. This is the most common and most expensive mistake. Separate applications mean separate hard inquiries, separate payments, and a worse rate on each, because every individual ticket is small. Get one quote from RecovAthlete covering everything you are buying, including freight, and put that single number on one application.
Financed equipment can qualify. Section 179 lets US businesses deduct the cost of qualifying equipment in the year it is placed in service, and financing the purchase does not by itself disqualify it. The equipment must be in service, not merely ordered, within the tax year. Annual limits and eligibility rules are set by the IRS and change year to year, so consult your accountant.
Freight, yes. On Affirm it is part of the order total at checkout. On business financing, put freight on the RecovAthlete quote and the whole quote amount goes on the application. Installation and room construction are harder, because some equipment lenders will not fund non-equipment costs. Ask the lender before you sign.
Yes. Affirm charges no prepayment penalties. Acorn Finance and most business lenders also allow early payoff without penalty.
Tell us what you are buying and whether it is personal or for a business. We will point you at the right two lenders and quote freight and install as one number, which is also the number that goes on the application.
