Common questions
Will it fit my chimney?
These extensions fit Harvia WHP chimney kits.
How long until it ships?
Lead times vary by model and season. We confirm the timeline when you order and contact you before it ships.
Will this heater fit my sauna?
Heaters are sized by the volume of the sauna room. Check the room size range in the specs above, or send us your sauna's inside dimensions and we'll confirm the right size.
Does a wood heater need electrical?
No. Wood-burning heaters need no power. You do need a proper chimney and the clearances listed in the manual.
Can I pay over time?
Yes. Choose Affirm or Klarna at checkout to split your order into monthly payments, subject to approval. You can also save 4% by paying with check, ACH or wire.
What about the warranty?
It's covered by the manufacturer's warranty. You don't have to deal with the brand yourself. Call us and we handle the claim for you.
