Cozy Cove Pro, Power Heat Pro and Heatoor are each sold as PTC ceramic heaters that can be wall-mounted or moved between rooms, and each comes with a remote. Toasty Heater is sold as a compact plug-in unit with a digital thermostat and timer. The differences that matter most are the wattage each seller states, the guarantee length and the return terms, and they are set side by side below.
You want a warm room you can sit in without dreading the power bill. This is desk research: it sets out what each seller publishes, next to government and utility guidance that applies to space heaters in general.

What does each seller say, and what do its returns require?
Cozy Cove Pro
The sales page says the heater uses “advanced PTC ceramic heating technology” and that “This powerful heater warms any space in 5 minutes.” Its specs list a power output of 400 to 800W and coverage of up to 549 sq ft. The headline reads “Slashing 30% Off Your Electric Bill!” Ask the seller what that 30% figure is measured against before you rely on it.
The return terms differ between pages. The homepage says “we will refund every penny. No questions asked.” The checkout says you receive “a full refund or replacement, less S&H” when you send the item back in its original packaging. The returns page, which names Onninest, sets 90 days from receipt, brand new and unused condition, an RMA number from customer service before you ship, and a 10% restocking fee that “may be made” plus any reconditioning charge. Ask the seller in writing which terms apply to your order.
The cozy cove pro heater reviews cover its specs, price and complaints in more detail.
Current pricing, eligibility and terms for Cozy Cove Pro are on the seller’s page: see Cozy Cove Pro details.
Power Heat Pro
The sales page says TurboWarm™ Technology “pushes 1800W of ceramic heat into the room you’re in.” Its FAQ says it is designed to help improve comfort in rooms up to 51 m², “depending on the room size, insulation, airflow, layout, and outdoor temperature.”
The shipping page says orders leave a New Jersey warehouse, the product ships within 48 business hours, and standard delivery takes 5 to 7 days. The FAQ gives 1 to 2 business days to process and 5 to 10 business days to deliver. Check the delivery window at checkout.
The returns page gives 30 days, with the item in the same condition it was received and in its original packaging. Include a note with your full name and the email you ordered with. Refunds post within 5 to 10 business days after inspection. You pay return shipping, and the page says the company may charge “a minimum of a 15% restocking fee.” The homepage lists “Free returns, no questions” as a trust point, so ask in writing which applies.
The warranty page offers a 3-year warranty and extended protection to new customers, and lists a warranty price of $9.95 for one unit. Support is by email at [email protected].
Current pricing, eligibility and terms for Power Heat Pro are on the seller’s page: see Power Heat Pro details.
Heatoor
The sales page says Heatoor’s “advanced PTC ceramic technology and 360° heat circulation deliver fast, even warmth across rooms up to 538 ft².” The FAQ says it “can comfortably warm rooms up to 50 m² (538 sq ft), depending on insulation and layout.” The page lists “Built-In Safety Auto Shut-Off” as a feature. For Heatoor, read the wattage from the label before you compare running costs.
The returns page asks you to contact support within 30 days of receiving your order. If the request qualifies, support sends an RMA form and a return address, and the page says “Do not send returns without prior approval.” Items are inspected for up to 7 days, and the refund goes to the original payment method, usually within 3 to 5 business days depending on your bank. Customers pay return shipping, original shipping is not refunded, and all included accessories must go back. The page asks you to email the return tracking number.
The FAQ lists a 1-year limited warranty. The shipping page says orders are typically processed within 24 hours. The company is named as Heatoor, with a phone line at +1 (812) 554-5750 and 24/7 live chat.
Current pricing, eligibility and terms for Heatoor are on the seller’s page: see Heatoor details.
Toasty Heater
The sales page calls it a “compact, cord-free portable heater” and says to “Plug it in a wall socket.” It lists “500 watts of power,” a thermostat from 60 to 90 degrees Fahrenheit, a timer that shuts off after 1 to 12 hours, and a 60-second cool-off before it turns off. The page uses both “cord-free” and wall-socket wording, so ask the seller what “cord-free” refers to.
The returns page was last updated September 11, 2023. It offers a 30-day satisfaction guarantee. Contact customer service first, and return within 30 days of taking delivery. Returns should arrive sealed, unopened and in their original condition, with a receipt. Return costs are not refunded. Refunds go to the original payment method and may take up to 10 business days to post after the return is processed and approved. Opened or partly used items are not accepted.
The company is named as Toasty Heaters, with support at [email protected] and +1 641 925 3165. The contact page lists a mailing address in Akron, Ohio. The shipping page says packages leave within 2 to 4 business days and points account tracking to electriclighters.com, so confirm the tracking link works before you buy.
What do they cost to buy?
The Cozy Cove Pro checkout, with promo code BF26 applied, showed a grand total of $99.99 for one unit, $159.98 for two and $179.97 for three, before shipping and tax, as of October 31, 2026. The checkout says shipping and tax are settled at confirmation.
For Power Heat Pro, Heatoor and Toasty Heater, check the price at checkout. Prices and offers change, so the checkout total, including shipping and tax, is the number to trust.
Do the room-size claims add up?
Save on Energy, an Ontario utility program, says “Manufacturers and retailers often suggest 10 watts of heating capacity per square foot of a room.” Its example is a 1,500-watt heater for a 150 square-foot room. The table sets each seller’s coverage figure beside that suggestion. The arithmetic uses only the wattage each seller gives.
| Heater | Stated wattage | Stated coverage | Check at 10 watts per sq ft |
|---|---|---|---|
| Cozy Cove Pro | 400 to 800 W | Up to 549 sq ft | 400 ÷ 549 = 0.73 W per sq ft; 800 ÷ 549 = 1.46 W per sq ft. At 10 W per sq ft, 549 sq ft would need 5,490 W. |
| Power Heat Pro | 1800 W | Up to 51 m² (about 549 sq ft) | 1,800 ÷ 549 = 3.28 W per sq ft. At 10 W per sq ft, 549 sq ft would need 5,490 W. |
| Heatoor | Up to 538 sq ft (50 m²) | Read the wattage from the label, then divide it by 538 to compare with the 10-watt suggestion. | |
| Toasty Heater | 500 W | 500 ÷ 10 = 50 sq ft. At the 10-watt suggestion, 500 W corresponds to about 50 sq ft. |
Cozy Cove Pro and Power Heat Pro both attach conditions to their coverage figures. Cozy’s FAQ names room layout, insulation, ceiling height and surrounding conditions. Power Heat Pro’s FAQ names room size, insulation, airflow, layout and outdoor temperature. Save on Energy’s 10-watt figure is a suggestion, so compare the two numbers and decide which one matches the room you are heating.
Which heater pulls the least electricity, and what does it cost to run?
The running cost is wattage divided by 1,000, times the hours run, times your electricity rate per kilowatt-hour. Save on Energy says heaters with the same wattage “will use the same amount of energy, assuming they’re used under the same circumstances.” So two heaters at the same wattage cost the same to run for the same hours, and the bill is set by the wattage and the hours.
The wattages the sellers print are the figures to compare. Cozy Cove Pro lists 400 to 800W, Toasty Heater lists 500 W and Power Heat Pro lists 1800W. For Heatoor, read the wattage from the label and run the same formula. Cozy Cove Pro’s sales page describes its heating as “energy-efficient,” and Heatoor’s says “Energy-efficient heating solutions.” Those are the sellers’ words. The number you can check yourself is the wattage.
The rate below is an example only: 18 cents per kilowatt-hour. The U.S. Energy Information Administration’s EIA Electric Power Monthly Table 5.6.A lists an average U.S. residential price of 18.16 cents per kilowatt-hour for August 2026, and notes that rates differ by state and utility. Use the rate on your own bill.
| Heater | Wattage | Per hour | 8 hours | 24 hours |
|---|---|---|---|---|
| Cozy Cove Pro, lower end of its range | 400 W | $0.07 | $0.58 | $1.73 |
| Cozy Cove Pro, upper end of its range | 800 W | $0.14 | $1.15 | $3.46 |
| Toasty Heater | 500 W | $0.09 | $0.72 | $2.16 |
| Power Heat Pro | 1800 W | $0.32 | $2.59 | $7.78 |
| Example: a 1,500 W heater (illustrative, not a seller’s figure) | 1500 W | $0.27 | $2.16 | $6.48 |
A 1,500 W heater run for 24 hours uses 36 kWh, which is $6.48 at 18 cents per kWh. These figures assume the heater runs at that wattage the whole time. A thermostat that cycles the element off uses less, so the real bill depends on the room, the setting and how often it runs.
To work out your own figure, multiply the wattage by the hours, divide by 1,000, then multiply by your rate. Our space heater running cost guide covers the rest of the running-cost math.
What type of heater suits a room?
Save on Energy describes the types this way. Convection heaters “come in a variety of sizes and heat up quickly.” Oil-filled heaters are “typically larger and a good option for heating a whole room,” but they are “slower to warm up and cool down after being turned off.” It also says “Models with fans may also be noisier,” and that allergy or asthma sufferers “may want to avoid a model that uses a fan, which would blow dust and allergens around.”
All four sellers describe their heaters for a room. Cozy Cove Pro and Power Heat Pro talk about the room you are using. Toasty Heater says it can “heat up any room in your house,” and its page carries the line “HEAT YOUR HOUSE IN NO TIME.” Heatoor’s page says “Warms your home in minutes.” Read the room-size figures above before you decide whether one unit fits your space. Save on Energy also notes that space heaters are “not certified under the ENERGY STAR program.”
What safety rules apply to all four?
The U.S. Consumer Product Safety Commission’s CPSC winter space heater news release says: “CPSC estimates that portable heaters, including electric space heaters, were involved in an average of 1,700 fires per year, resulting in an average of 70 deaths and 160 injuries annually from 2017 to 2019.” The U.S. Fire Administration’s USFA heating fire safety page says home portable heater fires “were only 3% of all home heating fires annually for 2017-2019, but they accounted for 41% of fatal heating fires in homes.” Those figures cover portable heaters as a whole, not these four models.
- Plug it straight into a wall outlet. CPSC says to “Always plug electric space heaters directly into a wall outlet and never into an extension cord or power strip.”
- Keep it at least three feet from anything that can burn. CPSC and USFA both give three feet.
- Turn it off when you leave the room or go to bed. CPSC says “Never leave portable heaters on while sleeping,” and USFA says to turn space heaters off “when leaving the room or going to bed.”
- Set it on a stable, flat surface where it cannot be knocked over. This advice comes from CPSC’s OnSafety blog post of January 13, 2017, which is an archived, outdated version.
- Check the plug, cord, outlet and faceplate for heat. If any part is hot, turn the heater off and have an electrician inspect it. This advice also comes from the archived 2017 post.
- Look for the seal of a nationally recognized testing laboratory such as UL. The archived 2017 post gives this advice, and CPSC’s older release of December 16, 2003 advises a heater “certified by a nationally recognized testing laboratory.”
- Never use an oven to heat your home, and have heating equipment and chimneys inspected each year by a professional, per USFA.
The sellers list their own safety features. Cozy Cove Pro lists “Auto shut-off activates if internal temperatures exceed safe levels,” Heatoor lists a “Built-In Safety Auto Shut-Off,” and Toasty Heater lists a 60-second cool-off. These are the sellers’ own words, and the CPSC and USFA rules above apply to every heater on this list. Our space heater safety guide covers fire risk, outlets and cost in more depth.
Before you order: a buyer checklist
- Wattage: confirm the figure on the product page or label. Cozy Cove Pro lists 400 to 800W, Power Heat Pro 1800W and Toasty Heater 500 W. For Heatoor, read it from the label.
