Helo vs Tylö sauna heaters

If you are comparing starting prices, Helo’s Cup STJ 9kW is listed from £326.39. Its name specifies 3-phase only, so keep that restriction in view when making your shortlist. Helo’s Hanko STJ is listed at 8kW from £407.75. Tylö’s lowest-priced entry is the Sense Commercial 6, listed at 6kW from £928.06.

For an 8kW comparison, you can look at the Hanko STJ alongside Tylö’s Sense Pure 8, listed from £1,659 with a Pure Control Panel. These entries differ in their stated panel inclusion, so do not judge the packages on price alone. The highest listed starting prices are £4,314.01 for Helo’s Rondo and £4,191 for Tylö’s Crown Combi Elite 6.

Tylö has four entries marked for app or Wi-Fi features; Helo has none marked in this comparison. The data does not identify which individual Tylö models have those features. If connectivity matters to you, use that figure as a starting point rather than a model-specific promise.

Helo’s summary spans 6.5–17kW, but the 17kW entry is named Elite Free Control Panel. Keep it separate from your heater shortlist. Tylö’s listed power range is 6–10.5kW. All listed heater power figures exceed the guide’s 3.6kW dedicated-circuit threshold.
