No reviews yet
We opened this year, so there are no reviews yet. Here are the numbers instead: 200 W, 6 heat settings, 6.0 hours . And if it isn't right, send it back within fourteen days.
What this is
- Two heated sides, two controllers, six settings each
- 100 W a side, where a plug-in radiator draws 2,000 W
- PTC element, specified by the manufacturer as faster to reach temperature
- Timer at two, four or six hours, set on each side
- 160 × 140 cm, laid under your sheet
One of you is always cold.
Two heated sides, two separate controllers, six settings each. One of you can have it on four while the other has it off. There is nothing to agree on, and no thermostat to argue over.
Each side draws 100 W on a PTC heating element: a wire whose resistance rises as it warms, so it draws less current the hotter it gets. The manufacturer specifies it as reaching temperature faster than a standard element. We have not measured it ourselves, so we do not publish a time.
Safety
It is an electrical appliance that spends the night under two people. So this is the second thing on the page, not the last.
- A timer you choose: two, four or six hours, set independently on each side. When it runs out, the power stops.
- Two controllers, so a setting on one side cannot be changed from the other.
- A PTC element, which draws less current as it warms rather than more.
- 220-240 V, on a BS 1363 three-pin plug.
Read the instructions before first use. The full text is in the box.
Before you use it
- Not for a baby, or a child who cannot work the controller.
- Not for anyone who cannot feel heat properly, or who could not react to it getting too hot.
- Do not use it folded or creased, and do not put it on top of you. This one goes under the sheet.
- Do not put pins or needles in it.
- Look at the cable and the fabric before each winter. If anything is scorched, frayed or cracked, stop using it and tell us.
- Unplug it before washing, and let it dry completely before it goes back on.
What it costs to run
At its highest setting, with both sides on, this underblanket draws 200 W, 100 W a side. A typical portable heater draws 2,000 W.
In energy: 0.80 kWh with both sides, 0.40 kWh with one, against 8.00 kWh for the heater.
We calculate on the full rated power for the whole four hours. A PTC element does not in fact draw its rated power continuously. But we have no measured duty cycle, so we assume the worst case, which overstates our own figure rather than the heater's.
This compares two appliances running for the same length of time. It is not a comparison of your heating bill.
Change the hours, the evenings per week and the tariff yourself: What it costs to run.
Material and care
Never put a controller in water. Let it dry fully before you use it again, and never switch it on to dry it.
Why it is safe to leave on
This is an electrical appliance you put on a bed. Here is exactly what stops it getting too hot.
- Switches itself off after 6.0 hours
Protections fitted
- Timer cut-off at 2, 4 or 6 hours on each side
- Two independent controllers
- PTC heating element
Certificates on file
We publish a certification mark only when we hold the certificate that names this exact model. We do not hold one for this product yet, so none is shown.

Sizes — Heated Underblankets - United Kingdom
Read this before you choose. Hazel and Rowan measure 150 by 80 cm single and 160 by 140 cm double: they warm the part of the bed you lie on, not the whole mattress. Oak measures 190 by 90 cm single and 190 by 140 cm double, which is the full length of most mattresses. Neither is a fault; they are two different products, and the difference is the reason Oak costs more.
