A heated throw or electric blanket is one of the most effective ways to stay warm in a cold house without running the central heating all evening. The electricity cost of a heated throw (typically 60-100W) is a fraction of the cost of heating a room, and the direct warmth is immediate rather than waiting 20-30 minutes for radiators to heat the air.
This guide explains the differences between heated throws (for the sofa) and electric underblankets (for the bed), and recommends the best models for each use.
Heated Throw vs Electric Blanket: What is the Difference?
Heated throws
Designed to wrap around you on the sofa or armchair. Softer, more flexible and usually larger than electric underblankets. Most have a built-in controller and flexible power cord that allows movement around the sofa.
Best for: Sofa warmth, watching TV in the evening, reading, working from home in a cold room
Electric underblankets (overblankets and mattress warmers)
Placed under the bottom sheet of the bed. Warms the bed before you get in and can be set to a lower temperature for sleeping. Most have multiple heat zones (foot warmth is different from body warmth for most people).
Best for: Pre-warming a cold bed, those who feel the cold at night, winter bed comfort
Heated overblankets
Place on top of you in bed rather than underneath. Less common than underblankets but available. Thinner and more flexible than heated throws.
Key Features to Look For
Heat settings: More is better. Two or three settings provide minimal flexibility; six to ten heat levels let you find the exact warmth you want.
Auto shut-off: Essential for safety. Most electric blankets shut off automatically after 1-3 hours. Longer auto-off timers (8-9 hours) are useful for underblankets used through the night.
Washable: All reputable modern electric blankets are machine washable. Check the temperature setting (usually 30C delicate cycle) and whether the controller must be removed first.
Size: Throws are typically 150 x 120 cm or 160 x 130 cm. Underblankets are available in single (90 x 150 cm), double (140 x 150 cm) and king sizes. Check dimensions against your needs.
Dual controls: Double bed underblankets with dual-zone controls allow each side to be set independently – essential for couples with different temperature preferences.
Material: Fleece throws are the warmest and softest feeling. Knitted or woven throws look more attractive on the sofa but may feel less cosy.
The Best Heated Throws in 2026
1. Silentnight Comfort Control Heated Throw – Best Overall Heated Throw
Silentnight is a trusted US bedding brand, and their Comfort Control heated throw is consistently rated the most balanced option. The large 160 x 120 cm size wraps comfortably around two people on a sofa. Nine heat settings allow precise adjustment and the 9-hour auto shut-off is the longest available in this category.
The fleece material is exceptionally soft and the wired controller has a long cable (2.5 m) that reaches from a socket without restricting movement.
Price: Around $50-60
Size: 160 x 120 cm
Heat settings: 9
Auto shut-off: 9 hours
Machine washable: Yes (remove controller)
What we like: Nine heat levels, 9-hour auto shut-off, very soft fleece, long cable, US brand
Worth knowing: Single controller (one temperature for the whole blanket); a dual-control version is not available in this range
2. Dreamland Intelliheat Faux Fur Heated Throw – Best Premium Throw
Dreamland’s Intelliheat system remembers your last heat setting and applies it automatically next time. The faux fur finish is a significant step up in tactile quality from standard fleece – genuinely luxurious. Six heat settings cover most preferences, and the 3-hour auto shut-off is shorter than Silentnight but configurable.
Available in multiple colours including grey and ivory.
Price: Around $75-90
Size: 160 x 120 cm
Heat settings: 6
Best for: Those who want a premium-feeling throw that also looks good on the sofa
What we like: Faux fur texture, memory setting, attractive design, Dreamland quality
Worth knowing: More expensive than Silentnight; 3-hour auto shut-off requires more manual resetting for long evenings
3. Homefront Electric Heated Throw – Best Budget Option
For those who want a functional heated throw without premium pricing, the Homefront is the most reliable budget option in the US market. Three heat settings are fewer than premium alternatives but cover warm, medium and low effectively. The sherpa fleece underside is notably softer than some competitors at this price.
Price: Around $30-40
Size: 150 x 120 cm
Heat settings: 3
What we like: Very affordable, sherpa fleece is comfortable, decent size
Worth knowing: Only 3 heat settings; 1-hour auto shut-off requires frequent resetting for longer use
The Best Electric Underblankets in 2026
4. Silentnight Comfort Control Electric Blanket – Best Underblanket
Silentnight’s underblanket is the market leader for US double and king-size beds. The dual-control double version allows each partner to set their own temperature independently – one of the most appreciated features for couples. Nine heat zones per control provide genuine precision.
Pre-heat mode warms the bed in around 20-30 minutes, then you can reduce to a lower setting or switch off entirely for sleeping.
Price: Around $45-60 depending on size (single to super king)
Sizes: Single, double (single and dual control), king, super king
Heat settings: 9 per controller
Machine washable: Yes (30C delicate)
What we like: Dual control option for double and above, 9 settings, trusted US brand, widely available
Worth knowing: Does not stay on all night at full heat – not designed for sleeping with on high setting (low setting or off for sleeping is safer)
5. Dreamland Intelliheat Plus Dual Control Electric Blanket – Best Premium Underblanket
Dreamland’s Intelliheat Plus is the premium underblanket with the most features: 25 heat levels per zone (significantly more than most), dual over-heat protection, and the Intelliheat memory system that returns to your preferred setting. The overheat protection is double-layer – useful reassurance for those who leave the blanket on a lower setting through the night.
Price: Around $75-90
Sizes: Double to super king (dual control)
Heat settings: 25 per zone
What we like: 25 heat levels is exceptional precision, double overheat protection, memory setting
Worth knowing: Premium price; most users will not need 25 heat settings but it is there
Safety: Using an Electric Blanket Properly
- Never fold a heated throw or blanket in use – folding concentrates heat and can damage the wiring
- Inspect the cable and blanket before each season – discard if there is any fraying, scorching or damage
- Do not use with hot water bottles – the combined heat can cause overheating
- Turn off or set to lowest before sleep (most models) – underblankets with a dedicated sleeping mode are designed to run overnight at low settings; standard underblankets should be turned off or to the lowest setting
- Do not dry-clean – only machine wash as instructed
Running Costs
A typical heated throw uses 60-100W. At current US electricity rates:
– 3 hours of use per evening: approximately 18-30p per night
– Monthly cost (30 evenings): approximately $6-9 per month
Compare to central heating a room (typically 1,500-2,500W for an electric radiator): heated throws cost roughly 20-25 times less electricity for equivalent personal warmth.
FAQ
Can you sleep with an electric blanket on all night?
Electric underblankets with a designated “sleeping through” low setting or auto 8-9 hour timer are designed for this purpose. Standard heated throws and most underblankets on medium-high settings should be turned off or to minimum before sleeping.
Are electric blankets safe?
Modern electric blankets meeting BS EN 60335 safety standard are safe when used according to instructions. Replace any blanket that is more than 10 years old, damaged, or shows scorching.
Do electric blankets work under a mattress topper?
Use the underblanket on top of the mattress, under the mattress topper and bottom sheet. Never place an electric blanket under the mattress.
