It is a matter of whether the heat is where you are standing. A workshop, a van, a boat cabin and a converted garage all share the same problem: the building was never designed with a heating system, and every winter the decision is made again to either endure it or spend four figures installing something permanent.\u003c\/p\u003e\n\u003cp\u003eThe Furnace Almanac is the portable answer to that problem. Inside a toolbox-shaped chassis sits a diesel burner rated at 8 kW, fed from an integrated 6 litre tank that consumes between 0.16 and 0.45 litres per hour depending on how hard the unit is working. It runs on 12 V or 24 V DC from a vehicle electrical system or on 110 to 240 V AC from a wall socket, which means the same heater can warm a bay during the day and a cabin overnight without being tied to one power source.\u003c\/p\u003e\n\u003cp\u003eThe details are where a heater stops being a heater. Adjustment spans 8 to 35 degrees Celsius, a remote and Bluetooth app reach the unit from up to 30 metres away, and adaptive plateau mode reads altitude automatically so the air-fuel mixture stays correct at heights up to 5,500 metres. The oil pump and radiator are rated from minus 40 degrees, the LCD switch carries a weekly timer with two heating windows per day, and the TB-10 PRO variant adds a wireless temperature sensing switch that also monitors carbon monoxide concentration in the space being heated. Overheat protection, a leak-proof fuel cap and a fuel level indicator close the loop on unattended use.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eWinter is not a season you survive.

Belongs\u003c\/h3\u003e\n\u003cp\u003eThis heater belongs to the buildings that have no heating system and never will. A workshop or garage where hands go numb before the job is finished, where a permanent installation is not worth the cost of the space. A van, truck or bivouac cabin in the shoulder seasons, running on the vehicle electrical system with a diesel tank that costs less to refill than a hotel night. A boat or narrowboat where moisture is the real enemy and ventilation mode does as much useful work as heat does. A livestock or storage building that must stay above freezing through a cold snap. Each of these places is temporary, movable or simply not worth a fixed heating plant, and each of them is exactly the case a portable 8 kW diesel burner was designed for.\u003c\/p\u003e\n\u003c\/div\u003e\u003cdiv class=\"product-promise\"\u003e\n\u003ch3\u003eSupport That Answers\u003c\/h3\u003e\n\u003cp\u003eEvery unit is checked before dispatch and shipped from the regional warehouse you select at checkout.

The unit accepts 12 V and 24 V DC from a vehicle electrical system and 110 to 240 V AC through the supplied adapter, so a workshop can run it from a socket while a van runs it from the battery. The 4 metre switch extension cable keeps the control panel within reach in either case.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom:15px;\"\u003e\n\u003cp style=\"margin:0 0 5px 0;\"\u003e\u003cstrong\u003eQ: How much fuel does an overnight run use?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp style=\"margin:0;\"\u003eA: Consumption spans 0.16 to 0.45 litres per hour depending on the power level requested and how cold the space is. In a well-insulated cabin held at constant temperature the low end of that range applies, which puts a full 6 litre tank in the region of a dozen hours or more of continuous heating.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom:15px;\"\u003e\n\u003cp style=\"margin:0 0 5px 0;\"\u003e\u003cstrong\u003eQ: What happens when the heater is used at altitude?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp style=\"margin:0;\"\u003eA: Adaptive plateau mode detects altitude automatically and displays it while adjusting the fuel-air mixture, and the unit is rated for use below 5,500 metres. That is the difference between a heater that soots up on a mountain road and one that keeps the flame clean.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom:15px;\"\u003e\n\u003cp style=\"margin:0 0 5px 0;\"\u003e\u003cstrong\u003eQ: Is carbon monoxide a concern with a diesel heater?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp style=\"margin:0;\"\u003eA: The exhaust must always be routed outside, exactly as with any combustion appliance. The TB-10 PRO variant adds a wireless sensing switch that monitors carbon monoxide concentration and ambient temperature in parallel with heater control, which is the version to choose where the space is enclosed or occupied overnight.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom:15px;\"\u003e\n\u003cp style=\"margin:0 0 5px 0;\"\u003e\u003cstrong\u003eQ: How loud is it inside a van or cabin?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp style=\"margin:0;\"\u003eA: The kit includes a silencer and an exhaust pipe specifically to reduce combustion noise, and the pump and fan are the dominant sounds in quiet use.
