Heater Buying Guide NZ 2026: How to Choose the Right Heater

How a heater actually warms a room

Every plug-in electric heater turns electricity into heat, and they are all close to 100 percent efficient at doing it, so the type you choose changes how the warmth is delivered rather than how much electricity a heater of that wattage uses. Oil column and panel heaters warm the surrounding air gradually through convection, which suits longer sessions such as an evening in a bedroom or study. Fan and ceramic heaters also heat the air, but use forced airflow to spread the warmth through the room quickly. Infrared radiant heaters direct heat towards people and surfaces rather than the air, which makes them the better choice for covered outdoor areas where warmed air would simply blow away.

Our top heater picks for 2026

Choosing the right heater starts with the room, how quickly you want it to warm up and how long you expect the heater to run. Below, we have shortlisted options for quiet bedroom heating, longer heating sessions, fast warmth in living areas and covered outdoor spaces. Explore the complete Heaters collection within our wider Heating & Cooling range.

How to choose from the Magness Benrow range

What size heater do you need?

Wattage is the first thing to match to your room. As a starting point, the panel heater maker Noirot suggests allowing around 100 watts per square metre of floor area, then adding headroom for rooms that lose heat quickly. Insulation, glazing, ceiling height, draughts, your local climate and whether the room can be closed off all shift the answer, so treat any rule of thumb as a starting point rather than a guarantee.

Heater size guide for NZ rooms

Suggested wattages are based on roughly 100 watts per square metre with an allowance for typical NZ conditions. Poorly insulated, draughty or high-ceilinged rooms need more.

A higher-wattage heater uses more electricity while operating at full output, but it may reach your selected temperature sooner and then cycle off through its thermostat. Overall energy use depends on how quickly the room loses heat, its insulation, your temperature setting and how long the heater runs, so choose enough capacity to heat the room comfortably without relying on unnecessary excess output. If a space is genuinely large or open-plan, EECA notes that a heat pump is far more efficient than plug-in electric heaters, putting out around three times more heat than the power it consumes, so weigh a big portable heater against a fixed heat pump over a whole winter.

Oil column, panel, fan or infrared?

Oil column heaters contain an electric element surrounded by permanently sealed oil. The heated oil warms the metal columns, which then warm the surrounding air gradually and keep releasing warmth after the thermostat cycles the heater off. Quiet and well suited to longer, steady heating sessions when used according to the manufacturer's instructions, they are a classic bedroom choice, though they are heavier and slower to warm up than other types.

Panel heaters are slim convection heaters that sit on castors or mount on a wall. The Noirot Spot Plus models run silently and suit bedrooms and studies, and the De'Longhi SlimStyle panel heater sits in the same family.

Fan and ceramic heaters blow warm air, so you feel the heat quickly and it spreads across the room, especially with oscillation. They are ideal for a fast morning warm-up, though they cool down quickly once switched off and make some noise.

Infrared radiant heaters heat people and objects directly rather than the air, which is why they stay effective on a covered deck where other types struggle. Indoors, they work best as spot heating.

Heater features worth paying for

A thermostat. This is one of the most useful features for running cost, because it lets the heater cycle off once the room is warm instead of running flat out. EECA advises choosing a heater with a built-in thermostat, which regulates the room temperature by controlling the power supplied to the heater and can reduce energy use by around 9 percent.

A timer. A timer lets you warm a bedroom before you wake or a lounge before you get home, and switch off automatically so you are not heating an empty room.

Safety cut-outs. Look for overheat protection and, on freestanding models, a tip-over switch. These matter most in homes with children or pets. The Noirot panels above include overheat protection, and the ceramic tower switches off automatically if tipped over.

Wall-mounting. A panel heater that mounts on the wall stays out of the way and off the floor. For rentals, some wall-mounted electric panel heaters may qualify as fixed heating in smaller living rooms, but only when permanently installed and when all Healthy Homes capacity, thermostat and installation requirements are met, so use the official heating assessment tool before purchasing.

Wi-Fi and app control. Genuinely useful if you want to schedule heating remotely, as on the De'Longhi Dragon5 Connect, but not worth paying extra for if you will never open the app.

Using a portable heater safely

A few habits make any portable heater much safer, whichever model you choose.

• Plug heaters directly into a wall socket, never into an extension lead or power board.
• Follow Fire and Emergency New Zealand's heater metre rule: keep clothing, curtains, bedding, furniture and anything else that can catch fire at least one metre away from the heater.
• Never cover a heater or use it to dry washing.
• Never leave a portable heater running when nobody is home. Only use a heater overnight where the manufacturer explicitly permits overnight operation, and always follow its clearance, thermostat and safety instructions.
• Only use a heater in a bathroom if the manufacturer explicitly confirms it is suitable for wet areas.

Heaters and the Healthy Homes standard

If you are a landlord, this matters before you buy. Under the Healthy Homes heating standard, the main living room of a rental must have one or more fixed heaters that can directly heat it to at least 18 degrees Celsius. Tenancy Services states that the heaters "must be fixed (not portable) and must be at least 1.5 kW in heating capacity and meet the minimum heating capacity needed for the main living room." Portable plug-in heaters do not qualify, regardless of their wattage. Electric heating is also capped, because Tenancy Services notes you "cannot use an electric heater (except a heat pump) if the required heating capacity for the main living room is over 2.4 kW," unless you are topping up qualifying heating installed before 1 July 2019. For most living rooms that means a heat pump, wood burner or flued gas heater is the practical answer. Some wall-mounted electric panel heaters may qualify as fixed heating in smaller living rooms, but only when permanently installed and when all Healthy Homes capacity, thermostat and installation requirements are met. Use the Tenancy Services heating assessment tool to work out the required capacity for your specific room before purchasing.

For bedrooms and supplementary comfort heating outside the main living room, where the standard does not require fixed heating, the portable oil column, panel and fan heaters in this guide are all practical options. As Tenancy Services notes, the World Health Organization recommends a minimum indoor temperature of 18 degrees Celsius, and EECA suggests keeping rooms around 18 degrees to help reduce damp and mould, which is a real issue in many older, poorly insulated New Zealand homes.

What heaters cost to run

MBIE's Quarterly Survey of Domestic Electricity Prices modelled a national retail electricity price of approximately 42 cents per kWh for its representative household in its 15 May 2026 survey. That figure reflects advertised plans for a typical household rather than what any individual customer actually pays, and the modelled rate varies widely by region, from about 37 cents per kWh in Wellington City to about 52.5 cents per kWh in Balclutha. At that indicative 42 cent rate, a 1000W heater costs around 42 cents per hour at full power, a 2000W heater around 84 cents, and a 2400W heater around $1.01. Because all plug-in electric heaters are close to 100 percent efficient, heaters of the same wattage cost about the same to run at full output whatever their type. To estimate your own cost, multiply the heater's output in kilowatts by the per-kWh rate on your electricity plan: a 2kW heater on a 35 cents per kWh plan, for example, costs about 70 cents per hour at full output. Your actual cost will depend on how often the thermostat cycles the heater on and off, and a timer reduces it further by keeping the heater off when the room is empty. If you are heating a large space every day through winter, a heat pump's much lower running cost can outweigh its higher purchase price over time.
