According to Truma, this saves space and weight in the vehicle, because the heater itself houses the 10-litre stainless steel tank.\u003c\/p\u003e\n\u003cp\u003eIt runs on LPG only (propane or butane at 30 mbar) and works at two power levels, 2000 W and 4000 W, which the unit chooses depending on the heat you need. Truma suggests it for small and medium-sized vehicles, with a gas consumption of 160 – 335 g\/h. If you are looking for a gas heater for a caravan of that size, this Combi 4 is Truma's answer.\u003c\/p\u003e\n\u003cp\u003eIt comes with the iNet X Panel control panel, which you operate from the touchscreen or from your phone. Note, though, that the box does not include the exhaust system or the water connection set, because you order both separately, and fitting is a job for qualified technicians.\u003c\/p\u003e\n\u003ch2\u003eBenefits of the Truma Combi 4 gas heater\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003cspan style=\"background-color: rgb(243, 253, 244); padding: 6px 12px; border-radius: 6px; display: inline-block; margin: 0px 0;\"\u003eTwo functions in one unit: it heats the vehicle and, at the same time, the water in the tank.\u003c\/span\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cspan style=\"background-color: rgb(243, 253, 244); padding: 6px 12px; border-radius: 6px; display: inline-block; margin: 0px 0;\"\u003eFour warm-air outlets that, according to Truma, distribute the heat optimally around the living space.\u003c\/span\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cspan style=\"background-color: rgb(243, 253, 244); padding: 6px 12px; border-radius: 6px; display: inline-block; margin: 0px 0;\"\u003eAutomatic output: it switches by itself from 2000 W to 4000 W depending on the difference between the set temperature and the ambient temperature.\u003c\/span\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cspan style=\"background-color: rgb(243, 253, 244); padding: 6px 12px; border-radius: 6px; display: inline-block; margin: 0px 0;\"\u003e10-litre stainless steel tank and, according to Truma, a short water heating time.\u003c\/span\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cspan style=\"background-color: rgb(243, 253, 244); padding: 6px 12px; border-radius: 6px; display: inline-block; margin: 0px 0;\"\u003eIt heats the living space even if the water tank is not full.\u003c\/span\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cspan style=\"background-color: rgb(243, 253, 244); padding: 6px 12px; border-radius: 6px; display: inline-block; margin: 0px 0;\"\u003eFan-assisted burner, designed to work while you drive too, provided the gas supply has a \u003ca href=\"\/en\/products\/regulador-gas-truma-monocontrol-cs\"\u003eMonoControl CS regulator\u003c\/a\u003e or another safety shut-off device.\u003c\/span\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cspan style=\"background-color: rgb(243, 253, 244); padding: 6px 12px; border-radius: 6px; display: inline-block; margin: 0px 0;\"\u003eLow consumption: 160 – 335 g\/h of gas and, according to Truma, low energy consumption.\u003c\/span\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cspan style=\"background-color: rgb(243, 253, 244); padding: 6px 12px; border-radius: 6px; display: inline-block; margin: 0px 0;\"\u003ePractically silent and extremely economical in operation, according to Truma's official website.\u003c\/span\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cspan style=\"background-color: rgb(243, 253, 244); padding: 6px 12px; border-radius: 6px; display: inline-block; margin: 0px 0;\"\u003ePart of the Truma iNet X system: you control it from the panel or from the app.\u003c\/span\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cspan style=\"background-color: rgb(243, 253, 244); padding: 6px 12px; border-radius: 6px; display: inline-block; margin: 0px 0;\"\u003eWeighs 14.4 kg without water, the lowest weight in the gas Combi range, which it shares with the Combi 6.\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eIs it compatible with your motorhome, campervan or caravan?\u003c\/h2\u003e\n\u003cp\u003eAccording to Truma, the Truma Combi 4 gas heater is approved only for motorhomes of vehicle class M1 and for caravans of class O, provided the gas installation complies with standard EN 1949.

When it is cold, the Truma Combi 4 gas heater warms the living area and heats the water at the same time. In summer you can select hot water only, and the burner then heats the tank on its lowest stage until the water reaches the desired temperature, at which point the burner switches off.\u003c\/p\u003e\n\u003cp\u003eWhen it works as a heater, the unit chooses the output stage by itself according to the difference between the temperature set on the control panel and the ambient temperature. While a room temperature sensor measures the air in the vehicle, other internal sensors monitor the water. Before it reaches the set value it reduces the output and, when the temperature drops, it switches on again without you doing anything.\u003c\/p\u003e\n\u003cp\u003eInside, the combustion air enters through the outer duct of the cowl and a fan carries it to the burner, which has two ignition electrodes and one flame-sensing electrode and ignites the mixture of gas and air. A circulation fan then blows the air over the fins of the heat exchanger and distributes it through four outlets.\u003c\/p\u003e\n\u003cp\u003eThe stainless steel tank is eccentric in shape. According to Truma, this makes the hot water circulate and mix better and gives it better thermal stratification, and the HDF thermal cover insulates the unit.\u003c\/p\u003e\n\u003ch3\u003eWith an empty tank and while driving\u003c\/h3\u003e\n\u003cp\u003eAn empty tank is not a problem, because the Combi 4 can work as a heater only.

Also use the safety and drain valve regularly, at least twice a year, to remove limescale and check that it has not seized up. For safety, children must not carry out maintenance or cleaning.\u003c\/p\u003e\n\u003cp\u003eYou must also sterilise and descale the water tank regularly. Cleaning products sold in camping shops are suitable and, to remove limescale, so are commercial descalers, vinegar essence or citric acid. Pour them in through the water inlet in the recommended proportion, leave them to work and rinse thoroughly with clean water.\u003c\/p\u003e\n\u003cp\u003eTo combat micro-organisms, Truma adds a complementary method: when the water reaches 60 °C the burner switches off, you keep the unit switched on for at least another 30 minutes and you do not draw any hot water, so that the residual heat takes it up to 70 °C.\u003c\/p\u003e\n\u003ch3\u003eFuse, solar installation and smell of gas\u003c\/h3\u003e\n\u003cp\u003eBefore opening the connection cover, disconnect the 12 V on all poles. Also, before touching the electronics you must establish equipotential bonding, because electrostatic charge can damage them beyond repair. Replace the fuse only with one of the same type, and then put the cover back.\u003c\/p\u003e\u003cp\u003eWith solar panels, when disconnecting the battery, disconnect the charge controller first and, when reconnecting, connect it last.\u003c\/p\u003e\n\u003cp\u003eIf you smell gas, Truma says to avoid any source of ignition, open windows and doors, evacuate the vehicle, close the gas cylinders and have the installation checked by technicians before using it again.\u003c\/p\u003e\n\u003ch3\u003eManufacturer's warranty\u003c\/h3\u003e\n\u003cp\u003eTruma offers a voluntary 24-month warranty against material or manufacturing defects, valid in the member states of the European Union, Iceland, Norway, Switzerland and Turkey. If there is a covered defect, the manufacturer or an authorised Service Partner repairs or replaces the unit. It is the manufacturer's warranty, it does not replace the statutory warranty and it excludes frost damage.\u003c\/p\u003e\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\u003ch3\u003eWhat is a Truma Combi boiler and what does the Truma Combi 4 gas heater do?\u003c\/h3\u003e\n\u003cp\u003eA Truma Combi boiler is a blown air heater with a built-in water heater. The Truma Combi 4 gas heater warms the living space and heats the 10 litres in its stainless steel tank with a single gas appliance, so you do not need a separate water heater.\u003c\/p\u003e\n\u003ch3\u003eCan I use the Truma Combi 4 gas heater while driving?\u003c\/h3\u003e\n\u003cp\u003eYes, but only if the installation has a safety shut-off device in accordance with UNECE Regulation 122, such as the MonoControl CS regulator. If it does not, you must keep the gas cylinder closed while driving and put warning signs in the gas locker and near the control panel.\u003c\/p\u003e\n\u003ch3\u003eIs the Truma Combi 4 gas heater suitable for my campervan?\u003c\/h3\u003e\n\u003cp\u003eYes, as long as the van is approved as a motorhome (vehicle class M1) and the gas installation complies with EN 1949. Truma also does not allow fitting it in commercial vehicles (class N). Truma designed this Combi for small and medium-sized vehicles, while the Combi 6 is for large ones.\u003c\/p\u003e\n\u003ch3\u003eCombi 4 or Combi 6: which one do I need?\u003c\/h3\u003e\n\u003cp\u003eIt depends on the size of the vehicle, because Truma sorts the Combi range into small, medium and large. While the Combi 4, at 2000 W and 4000 W, is for small and medium-sized vehicles, the Combi 6 reaches 6000 W and is for large vehicles. Both weigh 14.4 kg without water.\u003c\/p\u003e\n\u003ch3\u003eWhat else do I need to buy to install it?\u003c\/h3\u003e\n\u003cp\u003eThe box does not include the exhaust system or the water connection set with the FrostControl. It does not include the warm-air ducts either, which the unit needs to work. You also need a gas regulator, such as the MonoControl CS, and a qualified installer, because Truma only allows fitting by technicians.\u003c\/p\u003e","brand":"Truma","offers":[{"title":"Default Title","offer_id":55630400684374,"sku":"A0004860","price":2175.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0611\/9063\/5682\/files\/truma-combi-4-gas-vista-frontal.webp?v=1792394962","url":"https:\/\/evacaravan.com\/en\/products\/calefaccion-truma-combi-4-gas","provider":"Eva Caravan","version":"1.0","type":"link"}
