Winter buying guide
The right heater for the right room
South African homes mostly don’t have central heating — so picking the right electric heater for each room matters more here than almost anywhere in the world.
The good news: electric heat converts energy 1-to-1 into warmth — every watt you pay for becomes heat. What separates a cheap-to-own heater from an expensive-to-own one is control: avoiding overshoot, residual heat, and heating rooms nobody is in.
Room by room
Bedroom
You want silence, and something safe to leave on overnight. Sleep research puts the sweet spot at 16–18°C — warm enough to be comfortable, cool enough to sleep deeply. A panel heater on the wall holds that temperature silently all night, or choose an oil radiator if you wake up with a dry throat — oil heating is the gentlest on the air and doesn’t dry it out.
Bathroom
A bathroom heater must be rated for damp rooms — look for IPX4. Anything less doesn’t belong near steam. The clever move is scheduling: set it so the bathroom is already warm when you shower, not warming up while you shiver. The Mill panel is IPX4-rated and schedulable from the app; a PTC fan heater is the instant-heat alternative if you’d rather warm it on demand.
Home office
Working from home means hours in one room — you need silence and a steady temperature, not a heater cycling hot-cold behind you. A panel heater holds a precise, even temperature without a sound. If the room is freezing when you sit down at 08:00, either schedule the panel to pre-warm it, or keep a PTC fan for a quick warm-up.
Living room
The room the whole family shares needs even, silent, everyday warmth — a panel heater or oil radiator. Wall-mounting the panel frees up floor space (and keeps it away from kids and pets underfoot). The oil radiator keeps radiating gentle warmth even after it switches off.
Cold spots on freezing days
The garage-turned-gym, the guest room, the corner the sun never reaches. For occasional, on-demand heat, the PTC fan heater is the fastest room heater there is — compact, easy to carry, easy to store away in summer. The trade-off: it’s the noisiest type, so it’s for quick warmth, not all-evening company.
Where you put it matters
- Panel under the window. Cold air falls from the glass and spills across the floor — the “cold rush”. A panel mounted below the window sends warm air up to meet it, blocking the draft at its source.
- Low on the wall, not high. Hot air rises — a heater mounted high just warms the ceiling.
- Keep 10cm clearance around any heater, and never drape washing directly over it.
Heater types, honestly compared
Adapted from Mill’s European retail guidance. Fan heaters are genuinely the fastest — and genuinely the noisiest; oil is the slowest — and the kindest to the air. There is no free lunch, only the right tool per room.
The smart difference
Whatever type you choose, the biggest lever on your winter bill isn’t the heater — it’s control. A heater you can schedule and monitor from an app never heats an empty room, never overshoots your setting, and never runs all night because someone forgot the dial. International smart-heating studies show scheduled, precisely-controlled heating typically saves 10–20% versus a manual dial left on.
Mill’s range is smart across the board — panel, oil and portable — and every one of them carries a 5-year warranty.
