Silence is the most underrated feature of home heating. Fan heaters buzz, dry out your eyes, and kick up dust. Oil filled radiators act differently. They are the cast iron skillets of the heating world: they take a moment to get hot, but once they do, they radiate a steady, heavy warmth that lingers long after you unplug them.
They don’t burn oxygen, they don’t make noise, and they are incredibly efficient at maintaining temperature in medium sized rooms. However, the market is flooded with identical generic models and outdated listings. We have scrubbed the data for late 2025 to bring you the heaters that are actually in stock and worth your money.

A Note on Safety: Never use an extension cord with these units. Oil heaters draw high continuous amperage (usually 1500W). Extension cords add resistance, which creates heat and poses a fire risk. Plug them directly into the wall.
1. Best Overall: De’Longhi ComforTemp (EW7707CM)
De’Longhi remains the gold standard in this category. The ComforTemp model isn’t just about heat; it’s about engineering. Its signature feature is a dedicated button that automatically maintains the optimal temperature to save energya crucial feature when electricity rates are climbing.
In December 2025, this unit is widely available and sits at a sweet spot for pricingaround $116.35. Unlike cheaper clones, the oil reservoir is permanently sealed with high-quality welds, meaning leaks are virtually unheard of.
Why it wins:
- ComforTemp Button: One touch energy optimization.
- Thermal Mass: It holds heat longer than competitors after shut off.
- Availability: While other brands struggle with stock, De’Longhi supply chainssimilar to the robust logistics seen with Amazon FBA Germany—keep this Italian engineered unit available in the US.
2. Best Smart Heater: Aikoper 1500W Oil Filled Radiator
If you hate getting out of bed to adjust the dial, the Aikoper is your upgrade. Most oil heaters are analog dinosaurs, but this model brings the tech. It features a precise digital thermostat (adjustable from 40-95°F), a 24-hour timer, and crucially, a remote control.
Priced between $107 and $113, it includes an ECO mode that self regulates power (600W/900W/1500W) based on ambient temperature. It’s the modern choice for the smart home.
The Hidden Gem:
The “ECO” mode on this unit is aggressive. It will cut power drastically once the room hits the target temp, which can save you significant money on your monthly bill compared to a heater that just toggles full on and full off.
3. Best Budget Pick: PELONIS NY1507-14A
The Pelonis NY1507 is the workhorse of budget heating. It doesn’t look fancy, but it pumps out heat efficiently. However, we have to look at the reality of the market: as of late 2025, stock is volatile. You can find it listed around $82 to $90, but it often sells out at major retailers like Walmart.
If you see it in stock, grab it. If you are buying from a third-party seller because the main retailers are out, make sure you verify the store first. (Read our guide: Is Interconnect Shop Legit? A Comprehensive Review to learn how to spot safe sellers).
Key Features:
- Mobility: 360-degree swivel castors that actually roll (unlike cheap plastic wheels).
- Safety: Reliable tip over switch and overheat protection.
4. Best for Small Spaces: COSTWAY 700W Mini Radiator
Sometimes you don’t need to heat a whole room; you just need to heat your feet under a desk. The Costway 700W is a “mini” oil radiator. It is compact, uses half the electricity of a full sized unit, and fits in tight corners.
You can pick this up for roughly $45 – $70 depending on the vendor. It is perfect for home offices where a 1500W heater would trip the circuit breaker.
Advantages:
- Low Wattage: 700W draw is safer for older wiring.
- Silent: Zero noise, making it perfect for Zoom calls.
5. The Heavy Hitter: DeLonghi Dragon 4 (TRD40615E)
If you have a large, drafty room with high ceilings, the “Dragon” series is the industrial solution. It features a unique “chimney” design in the fins that pulls cold air from the floor and shoots it out the top faster than standard radiators.
Status Alert: This model is currently in a transition phase. While listed at $189.95, many retailers are marking it as “discontinued” or “out of stock” as De’Longhi shifts to newer models (like the TRD50615E). If you find the Dragon 4, it is still a top-tier machine with 25% more radiant surface area than the budget models.
6. The “Used Market” Legend: Honeywell HZ-789
The Honeywell HZ-789 EnergySmart was arguably one of the safest heaters ever made, featuring a 360-degree tip over switch and heavy insulated wiring. Unfortunately, it has been officially discontinued.
Why do we list it? Because it is robust enough to buy second-hand. You can often find these for around $75 on secondary markets. It’s the kind of treasure you might hunt for at the Best Street Markets in USA or garage sales. If you see one in good condition, it’s worth the pickup for the safety features alone.
