Instead of a door in the end wall, the entrance is in the side of the barrel, in the middle, through a timber door with a double glazed hexagon window. Step in and you are in a small entrance between two rooms: a sauna about 2.36 metres long behind a tempered, tinted glass door on one side, and a changing and relaxation room of the same length on the other, with an opening double glazed window and benches either side. It is the layout to choose if the barrel will sit side on to the house or the view, or if you want a proper room to sit in between rounds.\u003c\/p\u003e\n\u003ch3\u003eWhy the bands are stainless\u003c\/h3\u003e\n\u003cp\u003eA barrel only stays round and tight because the bands keep the staves pressed together. Timber shrinks each time the sauna is heated and dries out, then swells again through a wet British winter, so the bands work constantly and need checking and re-tightening over the life of the sauna. Ordinary steel bands eventually rust, and rust runs down the timber and stains it. Stainless steel does not, and on the Holvi it is standard.\u003c\/p\u003e\n\u003ch3\u003eWhat thermowood actually does\u003c\/h3\u003e\n\u003cp\u003eThermowood is timber that has been heat treated at around 200°C rather than chemically preserved. The process breaks down the sugars and resins that fungus feeds on and permanently reduces how much moisture the wood can reabsorb. The practical result outdoors is timber that moves less through wet British winters and resists rot without chemical treatment, in a structure that depends on staying tight.\u003c\/p\u003e\n\u003ch3\u003eChoose your heater at checkout\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eShell only.\u003c\/strong\u003e The complete sauna, you source your own heater.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHarvia Cilindro PC110 10.8kW.\u003c\/strong\u003e The largest Cilindro, with a taller stone column for the extra output, controls built into the heater.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHarvia Legend PO110XW 10.8kW WiFi.\u003c\/strong\u003e More output than the 9kW, with MyHarvia app control and the Harvia door sensor supplied.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHarvia Pro 20 wood fired.\u003c\/strong\u003e A 24.1kW log burning stove, rated by Harvia for rooms of 10 to 30m³, with a large firebox and a big load of stones.

The Holvi 590 Side hot room is about 8.8m³ (our estimate from the plan), which behaves more like 15m³. That is at the top of what a 9kW Cilindro is rated for and more than gas or the M3 should be asked to do, so on this model we offer the 10.8kW heaters and the larger Pro 20 wood stove instead. \u003c\/p\u003e\n\u003cp\u003eWe would rather sell you the right heater than the cheapest one.

The 10.8kW heater has its own supply requirement and we confirm that with you directly rather than printing a figure here. Budget for a qualified electrician and a Part P sign off. The wood fired options need no electrical supply for the heater.\u003c\/p\u003e\n\u003cp\u003eTell us your supply type and main fuse rating when you enquire and we will tell you honestly what will and
