Wider means you sit further from the heater and further from the person opposite, so a full session stays comfortable rather than cramped. The walls are 44mm thermally modified timber, thicker than the 38mm most imported barrels are built from.\u003c\/p\u003e\n\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, resists rot without chemical treatment, and holds its shape in a structure that depends on staying perfectly round.\u003c\/p\u003e\n\u003cp\u003eIt costs more. Across four UK retailers who sell the same barrel in both woods, the thermowood version runs 22% to 24% dearer than spruce. On a garden building that lives outside permanently, that is the upgrade worth paying for.\u003c\/p\u003e\n\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 barrel, you source your own heater.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHarvia Cilindro PC90 9kW.\u003c\/strong\u003e The classic Cilindro pillar with its tall stone column, 90kg of stones, controls built into the heater.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHarvia Cilindro PC90XW 9kW WiFi.\u003c\/strong\u003e The same heater with MyHarvia app control, so you can start it from the house.

On a barrel this wide, we would rather you had the headroom than not, especially on an exposed site or in February. It is £500 more than the 9kW WiFi.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWe would rather sell you the right heater than the cheapest one.

For the 9kW Harvia specify a 3 x 16A supply on three phase, or a single 50A supply on 10mm² cable if your property is single phase, which most UK homes are. Over a buried run to a garden building that cable size usually needs to go up again for voltage drop. Budget for a qualified electrician and a Part P sign off. The 10.8kW has its own supply requirement and we confirm that with you directly rather than printing a figure here.\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 will not work before you commit.\u003c\/p\u003e\n\n\u003ch3\u003eBuild and finish\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWalls:\u003c\/strong\u003e 44mm thermowood\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBenches:\u003c\/strong\u003e Linden\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFloor:\u003c\/strong\u003e Terrace boards\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRoof:\u003c\/strong\u003e Two layer bitumen shingles\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLighting:\u003c\/strong\u003e One internal and two external Harvia light fittings as standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBands:\u003c\/strong\u003e Tension bands\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat's included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBarrel shell in 44mm thermowood\u003c\/li\u003e\n\u003cli\u003ePre-cut wall staves and tension bands\u003c\/li\u003e\n\u003cli\u003eLinden benches\u003c\/li\u003e\n\u003cli\u003eTerrace board floor\u003c\/li\u003e\n\u003cli\u003eTwo layer bitumen shingle roof\u003c\/li\u003e\n\u003cli\u003eTempered glass door\u003c\/li\u003e\n\u003cli\u003eOne Harvia light fitting inside, two Harvia lights outside\u003c\/li\u003e\n\u003cli\u003eYour chosen Harvia heater, on all variants except shell only\u003c\/li\u003e\n\u003cli\u003eHarvia door sensor, on the two WiFi versions\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eOptions\u003c\/h3\u003e\n\u003cp\u003eAvailable to order on this barrel: L shaped two tier benches, a 50cm length extension, LED lighting under the benches, a Bluetooth speaker system, panoramic front or rear windows, stainless steel banding, and a choice of exterior finish and shingle colour.
