Harvia WHP1000 Chimney Extension: adds 39 inches for a taller roof
The Harvia WHP1000 Chimney Extension is a stainless steel section that adds height to a Harvia steel chimney. It gives you extra length to reach through a taller roof or rise farther above it. The section is insulated like the chimney and measures 8.6 inches across. It goes straight up only. The sections twist together, with grooves that hold them in place as the chimney heats and cools.
The box includes one stainless steel chimney extension. Need less height? See the shorter 20 inch Harvia WHP500 Chimney Extension. The Harvia WHP1000 Chimney Extension ships free from Norse Steam with No Sales Tax (except WY) and our 100% price match guarantee.
