Overview
The ESTIA EST-HW90 is a slim, vertical oil-filled radiator built for spaces where a bulkier heater would not fit comfortably, beside a desk, in the corner of a small bedroom, or under a table. At 38cm high, 28cm wide and 14cm deep, its footprint is smaller than most oil radiators, while it still heats rooms of up to roughly 10 square metres the same way any oil-filled heater does, by warming sealed oil inside its fins rather than blowing air.
Key Benefits
- Slim, vertical profile designed to fit tight spaces and under desks
- Adjustable thermostat for holding a steady, comfortable temperature
- Tip-over switch and automatic overheat protection built in
- Carry handle and a 1.5 metre power cord with an integrated cable tidy
- Oil-filled fins radiate steady heat with no fan noise
- White finish that suits most bedrooms, offices and living spaces
Performance

Like every oil-filled radiator, this heater takes a few minutes to build up heat rather than producing it instantly, and in exchange it runs quietly and holds its warmth well after the thermostat cuts the element off. That trade-off suits a room you occupy for a while, such as a home office through a working day or a bedroom overnight, better than a space you only pass through. Two power settings and the thermostat mean you are not limited to a single output: pick a lower setting for a mild evening and the higher one for a genuinely cold night, and let the thermostat take over from there. Because the unit is narrow rather than wide, it also does not need much clearance to stand safely away from curtains or furniture, which is useful in a compact bedroom or a shared office.
