Panel heaters are the fitted-look option: slim, silent, wall-mountable, and increasingly smart enough to schedule around cheap-rate electricity windows. They suit sealed modern rooms and background heating — not draughty period homes needing fast recovery. We compared thermostat accuracy, scheduling intelligence and build across the five best sold here.

Buying guide: how to choose
All electric heaters are '100% efficient' — read that right
A 2,000 W heater produces 2,000 W of heat whether it costs €30 or €300. What you're paying more for: better thermostats (less wasted run-time), heat retention (oil columns), safety features, and quieter or faster delivery. 'Eco ceramic' marketing changes nothing about the physics.
Match the type to the job
Quick blast in a bathroom: fan heater. All-evening living room warmth: oil-filled radiator (retains heat, cycles less). Heating just yourself at a desk: radiant/halogen pointed at you. Whole-room slow background: panel with timer. Wrong type = higher bills.
The real cost per hour
At ~36c/kWh standard rate: a 2 kW heater flat-out costs ~72c/hour; a 1 kW setting ~36c/hour; a 500 W radiant ~18c/hour. A good thermostat halves effective run-time — that's where savings genuinely live.
Spot heating beats whole-home electric
Electric heating a whole Irish house is brutal on bills. The winning strategy: keep central heating low, spot-heat the occupied room. A 1 kW oil radiator in a home office for 8 hours (~€1.50–2.50 with thermostat cycling) beats firing gas through the whole house.
Frequently asked questions
Can an electric heater heat a whole room?
Yes — allow roughly 100 W per square metre in a typically insulated Irish room (so 1,500 W for a 15 m² room). Poor insulation or high ceilings need more. Close the door: the cheapest upgrade for any heater is a closed door.
Electric heater or heat pump — what about running costs?
A heat pump delivers 3–4 units of heat per unit of electricity, versus 1:1 for any plug-in heater — but costs thousands installed. For heating one room a few hours daily, a plug-in heater is rational; for whole-home daily heating, the heat pump wins long-term.
What's the cheapest electric heater to run in Ireland?
The one with the lowest wattage that does the job, run through a good thermostat. For heating a person: a 400–800 W radiant heater. For a room: an oil-filled radiator on a thermostat cycles off once warm, often averaging half its rated draw across an evening.
