A small detail. A whole sauna to imagine.

Why embed your heater?
Good sauna design aims to keep your feet near or above the top of the heater stones. Warm air rises, so a low foot bench can leave your feet in cooler air while your head gets hot. Planning the seat and footrest heights around the stone level helps bring more of your body into the warmer part of the sauna.
Embedding your 10.5 kW Cilindro Half into a raised bench or platform lets you build the layout around the heater, with this flange finishing the opening. The bench and footrest heights create the relationship between your feet and the stones; the flange alone does not change it. Keep the required portion of the heater above the surrounding surface and follow the heater and flange manuals for clearances, ventilation, mounting and service access.
Start with the Cilindro. Finish with the flange.
A stone-filled Cilindro rising through a timber bench can become the center of the sauna. The HPC7 completes that junction: a stainless steel sleeve drops into the opening, with its rolled rim resting above the wood. The heater stands on the floor below.
If you are still planning your sauna, choose the heater for your room first. Then match its control, stones, flange and bench layout. HPC7 is the accessory for the U.S. 10.5 kW Cilindro Half.
Why build around a Cilindro?
The tall stone basket makes the heater a visible part of the sauna. Harvia describes changing the character of the steam by directing water toward the side or top of the stone pillar. A bench integration keeps that stone tower in view while bringing the timber surface around its base. Choose the right heater size first, then plan the surrounding bench.
What the flange does
The sleeve shields the surrounding bench from radiant heat and finishes the cut edge. Harvia allows the bench to sit closer to the heater when the approved flange is installed according to its instructions. The visible rim makes the heater and bench read as a single planned detail.
- Stainless steel: an open sleeve with a rolled upper rim.
- Size-specific: match the flange to the heater’s exact model, not just its family name.
- Unlit: HPC7 has no integrated light or electrical connection.
- Floor-supported heater: the flange does not carry the weight of the heater and stones.
Will HPC7 fit my Cilindro?
For the U.S. product sold here, pair HPC7 with the 10.5 kW Cilindro Half. Harvia’s USA/Canada flange guide lists HPC(S)11U1H and HPC(S)11U3H as compatible. Its smaller 7/9-series rows do not accept HPC7. Product names such as PC110E and “11 kW” can appear alongside the U.S. 10.5 kW rating; use the exact heater code when matching accessories.
Harvia’s global HPC7 page also names European PC165E/PC200E heaters. That global naming does not replace the U.S. compatibility table. If you are choosing a smaller Cilindro, select its matching flange with the heater package.
Plan the opening before building the bench
- Choose and size the heater. Account for the finished room and exposed glass or masonry, then select the correct electrical configuration and control.
- Set the bench level. Harvia’s U.S. flange drawing limits the bench surface to 27.5 in above the floor and timber thickness to 1.9 in.
- Use the actual flange to mark the opening. The drawing calls for a minimum 0.4 in gap around the sleeve at the timber opening. The 19.9 in collar dimension is not a ready-to-cut hole size.
- Plan access underneath. Leave a practical route to the heater connections, cleaning area and stone basket. Follow the heater manual for all other clearances, ventilation, sensor placement and electrical work.
What to include in your Cilindro plan
The heater
Choose the output and electrical configuration for your sauna. The 10.5 kW Half is the HPC7 pairing shown here.
Control and stones
Choose the compatible control package and required sauna stones on the Cilindro page. Review the selected package contents before checkout.
Bench and accessories
Add the matching flange if embedding the heater. A safety railing is a separate accessory; the metal flange does not replace one.
Questions worth answering before you order
Can I buy just the flange for a heater I already own?
Yes. Confirm the exact heater code and bench detail first, then use this page’s Add to cart button for HPC7. The heater, control, stones and timber are not included with this accessory.
Can it sit in a raised platform instead of a seat?
The illustrated arrangement is a timber surface surrounding a floor-standing heater. The same flange detail must remain within Harvia’s specified height, timber thickness and opening-gap limits. The interactive platform is a planning illustration; your installer must verify the complete layout against the heater and flange instructions.
Is HPC7 a safety railing?
No. It finishes and shields the bench opening. A railing helps keep bathers away from the hot heater above the bench and is selected separately.
Does this flange have lighting?
No. HPC7 is the unlit stainless steel flange. Illuminated Harvia flanges are separate accessories with their own compatibility and installation instructions.
How big is it?
Harvia’s U.S. drawing labels the HPC7 collar diameter as 19.9 in and its sleeve height as 5.9 in. Measure the supplied flange and follow the drawing when laying out the opening; do not use the collar diameter alone as a cutting template.
What comes with HPC7?
The embedding flange and installation instructions. The heater, control, sauna stones, bench timber and any safety railing are separate. Harvia’s limited warranty is two years for consumer use and one year for commercial use, subject to its warranty terms.

Choose your Cilindro, review its control and stone package, then add the bench detail that fits your plan.
