Sauna Water Heater

Finnish sauna giant, Harvia, is the only one manufacturing water heaters for saunas at the moment. They have two free standing models that need to be lighted separately from the stove itself. Harvia also has an add-on, half of which is filled with stones and the other half has a 6.6 gallon water tank. Harvia Legend Pipe water heater enhances the look of your sauna stove, since it’s wrapped around the smoke exhaust pipe. It also gives you one additional place with rocks to throw water in, to get some softer steam since those stones don’t get as hot as the ones closer to the fire chamber of the stove.

Installing a sauna replacement heater is super simple. If you get the Legend Pipe water heater, you just place it on top of the stove around the smoke exhaust pipe and throw in some rocks for the cage. The Harvia WP models, you need to plan and measure a place to put the water heater in. I have seen most people place it on the corner somewhere near the door, but there’s no official guide to it. If you eventually end up replacing your wood stove or upgrading it, you don’t need to upgrade the water heater since they don’t wear out and there’s no new ones being developed.

When it comes to safety, it’s important to ensure you meet all safety distances. With free standing WP models, you need to keep at least a 6 inch cap to any combustible materials that your sauna might have. You can also build a safety rail around the free standing water heaters. The sauna water heaters are mounted into the smoke exhaust pipe, you don’t need to worry about the safety distances since the stove placement should already meet those.
