A heating problem can also begin with a poorly closing window or warm air that never reaches the seating area. Work in a useful order: assess the room, select the heating method and calculate consumption before adding equipment. The purchase price does not tell you the cost of an evening's heating. Nor does a small appliance necessarily draw little electricity.
Choose an appliance for the time and space involved
For a room occupied for several hours, start by assessing the existing air conditioner. The Ministry of Health highlights its comparatively low operating costs and the benefit of mounting it away from direct contact. This does not make every unit suitable for every room: size, insulation and outdoor conditions matter.
An oil-filled radiator can suit a small or medium room when immediate heat is unnecessary. It warms gradually, so do not judge it solely by the first moments after switching it on. Equally, do not move it close to an armchair to compensate for the wait. Choose a position that maintains safe clearance when the room is occupied.
A fan heater directs warm air toward a limited area, which can make it appealing for brief use. A model described as ceramic still needs its wattage, instructions and safety features checked. The name does not establish its running cost or remove the need for supervision and clearance.
Compare appliances doing the same job. Warming a desk area briefly and heating a living room all evening are different tasks. Write down where people sit, how long they stay and whether children or pets could approach the appliance. This gives you a practical basis for choosing rather than relying on a general claim on the packaging.
Read the wattage and separate energy cost from the bill
Electrical input is generally expressed in watts, marked W. Divide watts by 1,000 to obtain kilowatts, then multiply by operating hours to calculate kilowatt-hours, or kWh. Multiply that result by the price per kWh. Use electrical input, not a separate heating-output figure where both are provided.
The Electricity Authority's tariff table effective July 1, 2026 lists the uniform domestic energy rate as 53.83 agorot per kWh before VAT. With 18% VAT, this is approximately 63.52 agorot, or NIS 0.6352 per kWh. This covers energy consumption only. The bill also contains fixed and capacity charges; another tariff arrangement or a personal discount can change the calculation.
For illustration only, an appliance drawing 2,000 watts continuously for four hours consumes 8 kWh. At NIS 0.6352 per kWh, the energy cost is approximately NIS 5.08 including VAT. This is an arithmetic example, not a prediction for a particular radiator or air conditioner, and not the household's total electricity bill.
If a thermostat switches the heating element off during part of that period, the appliance does not draw its maximum input continuously. Equipment that varies its input also cannot be modeled accurately as operating at maximum throughout. Label wattage helps establish scale; actual consumption gives a better picture of your use.
Check the air conditioner before raising the setting
Confirm that the unit is in heating mode rather than fan-only mode. Check its filters against the instructions. The Standards Institution of Israel recommends periodic filter cleaning and keeping the air intake and outlet clear. Follow the manufacturer's shutdown and disconnection instructions before cleaning accessible parts; leave internal servicing and repairs to a professional.
The institution also recommends directing warm airflow downward to help distribute heat. Before increasing the temperature again, check for obstructing furniture and whether the airflow reaches the seating area. Adjusting where you sit is a reasonable first experiment before introducing another heater.
There is no single setting suitable for every occupant and room. The Ministry of Health's guidance for older adults gives a living-area range of 20 to 24 degrees Celsius and recommends using a thermometer. Consider the people in the room and its measured temperature, rather than relying solely on the remote's display. Cutting costs should not mean leaving someone vulnerable to cold in unsuitable conditions.
Choose the safe position before connecting the plug
A portable heater belongs on a stable surface away from curtains, sofas, rugs and blankets. The Ministry of Health's guidance recommends at least three meters from combustible materials. If the room cannot accommodate that clearance, do not improvise a crowded position. Consider another heating arrangement appropriate to the space and its operating instructions.
Connect a portable heater or radiator directly to a suitable wall socket, without a power strip or extension cord. Check the cord and plug for damage. The Standards Institution says a warming plug or a socket turning brownish-yellow calls for a licensed electrician. Stop using a suspect connection; an extra adapter or a do-it-yourself socket replacement does not resolve the problem.
Never cover a heater or place laundry on it, even if the clothes seem only slightly damp. Keep air openings clear and cords away from hot parts. Oil leakage or a deformed radiator body is a reason to stop using it, according to the Standards Institution.
Check for a tip-over shutoff, but do not treat it as supervision. Turn portable heating appliances off when leaving the room and before sleeping. Overnight heating requires a solution specifically intended for that use, installed correctly and consistent with safety guidance. Adding a timer does not make an unsuitable heater safe to leave operating.
A bathroom needs equipment designed for that environment
Do not move an ordinary living-room fan heater into the bathroom simply because it is portable. Water and damp conditions require explicit suitability of the appliance and installation. Check the model instructions and proposed location with a licensed electrician. Appearance, or a socket that seems far from the bathtub, is not enough.
If there is no suitable dedicated solution, do not improvise with an extension cord from another room. The question is whether heating can be provided under the permitted conditions. Preparing clothes and a towel beforehand and keeping the floor clear are useful organizational steps. They do not replace necessary heating, but help avoid a rushed decision involving unsuitable equipment.
Do not bring combustion indoors to save electricity
Carbon monoxide is a poisonous gas that cannot be recognized by smell or color and can form during incomplete combustion. Never bring a barbecue or burning charcoal indoors for heat. A small fire or a slightly open window does not turn this into a safe heating method.
The Ministry of Health recommends avoiding gas, kerosene and exposed-coil heaters in its household guidance. An existing combustion system requires authorized professional installation and servicing in accordance with its requirements. Do not block dedicated ventilation to stop a draft or use a cooking appliance as a room heater.
If a headache, dizziness or nausea develops where a combustion appliance is operating, do not remain inside to see whether it passes. Move into fresh air and seek urgent medical help. Leave investigation of the fault and permission to resume use to qualified personnel. The Ministry of Health's heating safety guidance provides the broader household recommendations.
Reduce drafts and finish with a brief daily check
Check that windows and doors close properly, and address gaps with suitable sealing. Preserve required ventilation and keep dedicated vents open. If there are damp patches or mold, investigate the cause as well: raising the heating setting does not identify a leak. The guide to preparing a home for rain, damp and mold addresses that separate task.
At the end of the day, check what remains on, whether objects have moved toward the heater and whether cords remain clear. Decide who switches off the portable appliance when the room empties. A useful heating routine combines suitable equipment, a suitable room and a habit the household can follow even when everyone is tired.
