Oil Filled Radiator Heater 1500W - Quiet, Energy Saving Room Heater

In this review of the De'Longhi oil filled radiator heater EW7707CB, the bottom line is simple: it is a solid choice for someone who wants quiet, steady warmth for a small to medium room without the fuss of installation. The reviewer found the heater especially useful for bedrooms and home offices, where low noise and a gentle radiant heat matter more than fast air blasting. The built-in ComfortTemp feature and simple controls make it easy to save energy while maintaining a comfortable temperature all evening.

Key Features

• 1500W power: Provides long lasting, quiet heat suitable for small to medium sized rooms so a single unit can warm a bedroom or home office effectively.
• ComfortTemp feature: Automatically maintains optimal temperature and lowers power use by up to 20% versus running at max, which helps reduce energy waste and electric bills.
• Thermal slot design: Maximizes heat flow into the room while keeping the unit surface relatively cool, which is helpful around pets and children.
• Oil-filled, sealed reservoir: Permanently sealed diathermic oil means no refilling and low maintenance with corrosion-resistant metal construction.
• Safety elements: Includes thermal cut-off and fully enclosed heating elements for a safer operation and peace of mind in occupied rooms.
• Portability: Integrated handle and smart snap wheels allow easy relocation between rooms without tools or installation.

Who It's For

This heater is best for people who need a quiet, maintenance-free heat source for bedrooms, living rooms, or home offices and who value steady radiant warmth over rapid forced-air heating. It suits users who want safety features and a low surface temperature because of pets or children.

It is less ideal for those who need instant high-output heat for large open-plan spaces or who prefer a fan-forced heater for quick temperature changes; for very large rooms a higher capacity solution would be a better choice.

Pros & Cons

Pros

• Quiet operation that does not stir up dust or allergens, improving comfort for sensitive users.
• Energy-saving ComfortTemp feature that helps reduce running costs compared with leaving a unit at full blast.
• Durable, low-maintenance build with a permanently sealed oil reservoir and corrosion-resistant finish.
• Easy to move with integrated handle and snap wheels, making it practical for multi-room use.

Cons

• Not designed for instant whole-house heating; best for single rooms or small to medium spaces.
• Heats more slowly than fan-based heaters, so it requires some time to reach set temperature.
