The one accessory we argue for
We are usually happy to let people skip accessories. Not this one. A floor-standing cylinder heater puts its hottest surface exactly where a knee, a calf or a child’s hand goes, and the difference between a contact burn and a near miss is a two inch gap. The HPC3 provides that gap.
How it is built
Four wooden arches, joined to each other and mounted to the heater on stainless steel brackets. The wood is heat-treated birch, which is the right choice here for the same reason it is the right choice for benches: thermal modification drives the moisture out so the timber stays dimensionally stable through years of heat cycling instead of cupping and cracking. It measures 20.1 inches wide by 20.1 inches deep and weighs 5.1 pounds.
Which heater it fits
This is the guard for the Harvia Cilindro in 6 kW and 8 kW. The 10.5 kW model takes a different railing, so check your heater’s kW before ordering. If you want the version with lighting built into it, look at the HPCU4LUL railing with LED.

If children use the sauna
Then this is not optional in our view, and neither is the conversation about bench height. Rails stop the accidental contact. They do not make a heater safe to lean on, and they are not a substitute for the clearances in the installation manual.
