Warranty as per Havells terms and conditions — 2 year warranty as stated in supplier material. The scope of cover, coverage of the heating element, PTC fan, thermostat, safety switches, control panel, oil-filled radiator body, cord, plug and accessories, parts and labour, exclusions, product registration and the service process are subject to Havells brand policy and the final invoice or warranty documentation. Damage arising from misuse, covering the appliance, use for drying clothing, operation near combustible materials, connection to an inadequate or unearthed electrical supply or through unsuitable extension boards, operation while not upright, liquid ingress or unauthorised servicing is commonly excluded. Required socket rating is not stated in supplier material; at a total rated output of 2900 W on a 230 V supply the current draw is approximately 12.6 A, which exceeds the rating of standard 6A domestic sockets, and a 16A socket on an adequately rated and properly earthed circuit should be confirmed as available before purchase. Some images on this listing appear to depict a 9-fin 2400 W Hestio model rather than the 15-fin GHROFCTK290 at 2900 W described here; the model designation on the product carton and invoice should be treated as definitive and confirmed at delivery. Recommended room size, thermostat temperature range and whether the control sets an absolute temperature or a relative level, timer, remote control, PTC fan noise level, cord length and box contents are not stated in supplier material and should be confirmed before purchase. Rated outputs of 2900 W total, 2500 W radiator and 400 W PTC fan, the three heat settings, fin count and profile, certification to IS 302-2-30, dimensions and weight are manufacturer specifications; actual warm-up time, perceived warmth, area heated, heat retention after switch-off and running cost vary with room size, ceiling height, insulation, draughts, outdoor temperature, occupancy, selected setting, thermostat position, duration of use, supply voltage and the applicable electricity tariff slab. Statements about relative running cost between settings describe the proportional difference in rated power draw and are not a guarantee of any particular bill. Certification and the standard reference are as stated in supplier material and should be verified on the product marking. Descriptions of the exterior as cool-touch and of operation as whisper-quiet are the manufacturer's own product descriptions: the radiator fins become warm in use, and the PTC fan produces noise when running even though the radiator alone does not. Explanations of oil-filled radiator operation, fin surface area and profile, PTC element behaviour and heater type comparisons provided here are general information to aid understanding and are not manufacturer specifications. This product is a household appliance and not a medical device; no health, respiratory, humidity or air-quality outcome is claimed or implied, and heating any room reduces its relative humidity regardless of heater type. The appliance must be kept upright at all times, must never be covered or used to dry clothing, must be kept clear of curtains, bedding, upholstery, paper and furniture with free air circulation on all sides, must be placed level on a firm floor, and must be connected to a properly earthed socket of adequate rating and not through light-duty extension boards, multi-way adaptors or external timers or automatic switching devices. The oil circuit is sealed and must never be opened, drained, refilled or repaired; the appliance must be taken out of service if any fin is damaged or leaking. It must not be used in bathrooms, near water or with wet hands. It must not be left operating unattended in rooms with young children, and must be unplugged and allowed to cool before being moved, cleaned or stored. Discontinue use and seek service if the cord or plug is damaged, if the appliance trips the electrical supply, if burning odour or oil leakage is observed, or if the tip-over switch fails to cut power when the appliance is tilted.
