{"title":"Harvia","description":"\u003cp\u003eHarvia has made sauna heaters since 1950. The range here runs from barrel saunas for the garden to indoor cabins, from an infrared cabin that runs from an ordinary socket to glass fronted traditional rooms, alongside the Frosty chilled plunge bath. Every price includes the heater or cooling unit, and delivery.\u003c\/p\u003e","products":[{"product_id":"harvia-kuusi-180-panorama-barrel-sauna","title":"Harvia Kuusi 180 Panorama: 4 Person Barrel Sauna","description":"\u003cp\u003eThe Kuusi 180 is the barrel sauna in the range: a 2,200mm diameter cylinder of 40mm solid spruce staves, 1,800mm long, pulled tight by two steel bands and standing on four impregnated feet. Four people sit on two 600mm benches facing each other across a 686mm walkway, and the half height window in the rear wall, which is what Panorama means on this cabin, puts the garden behind you rather than a blank wall. It is the sauna for a household that wants four seats with the heater already chosen and in the price, and is happy to build it.\u003c\/p\u003e\n\u003cp\u003eA barrel is a different proposition from an insulated cabin, and the difference is worth understanding before you buy rather than after. The wall is a single 40mm stave with nothing behind it, so the room loses heat faster than a cabin with insulated walls and takes longer to reach temperature on a cold night. Harvia's own sizing rule adds half again to the room volume for uninsulated timber walls, which takes the 5.6 cubic metre room to 8.4.\u003c\/p\u003e\n\u003cp\u003eThere are two ways to heat it. The electric version has the Harvia Wall SW80, 8kW, wall mounted opposite the door, with a timer dial that runs it for up to four hours or starts it by itself up to eight hours ahead, and a thermostat dial. At 230V it draws 34.8 amps, which is our arithmetic, and Harvia publish a 50A fuse for it, on a single phase circuit installed by an electrician. The wood burning version has the Harvia Linear 18, rated by Harvia for rooms of 5 to 18 cubic metres, with its steel chimney kit for barrel saunas, protective bedding and 40kg of stones, and it needs no heater circuit at all.\u003c\/p\u003e\n\u003cp\u003eThe spruce arrives untreated. Harvia recommend painting or treating the outside to extend its life and say the inside must be left bare. They also say plainly that a barrel is not fully watertight in driving rain: two drain holes in the lowest stave let water out, and the timber under the glass can mark with condensation, which is why the cabin should be dried out by heating it after wet weather. None of that is a fault. It is what a single skin timber barrel is, and the price reflects it.\u003c\/p\u003e\n\u003cp\u003eThe cabin, the Panorama window, the 8mm glass door, the two benches and backrests, the floor grid, the roof shingles, the 760mm dimmable LED strip, the heater you choose and its stones are all in the one price.
