Dimplex DLW Series Electric Patio Heater 1500W - Weatherproof Radiant

In this review the Dimplex DLW Series electric patio heater is assessed for homeowners and small-business operators who want reliable, localized warmth without glare. The bottom line: this slim, weatherproof radiant heater is best for ceiling or wall mounting where a permanent, hardwired installation is acceptable, and it excels at extending outdoor living and dining comfort through cool evenings. Its IP55-rated construction and focused long-wave infrared output make it a practical choice for patios, porches, and indoor seating areas that need unobtrusive, efficient heat.

Key Features

• Advanced Heating: Long-wave radiant output delivers targeted warmth to people and surfaces without visible glare, making outdoor dining more comfortable.
• Versatile Mounting: The slim profile supports both wall and ceiling installation, offering flexibility for patios, decks, and indoor alcoves.
• Weatherproof Construction: IP55-rated housing protects the unit from dust and water spray, so it can remain installed year-round on porches and uncovered patios.
• Hardwired Installation: A top-mounted junction box is provided for permanent hardwiring, improving safety by eliminating exposed plugs and cords.
• Sleek Modern Design: The slim white finish blends with contemporary decor while staying visually unobtrusive above seating or dining areas.
• Reliable Output: The 1500W, 240V long-wave element offers consistent, immediate radiant warmth in focused zones.

Who It's For

The DLW Series 1500W model is ideal for homeowners with a covered patio, porch, or small deck who want a discreet, permanently installed heater that delivers direct radiant warmth for seating and dining. It also suits small restaurants and cafes that need a weatherproof solution to keep guests comfortable outdoors without bright light or bulky stands.

It is not the best choice for renters or those who prefer plug-in portability, since the heater requires permanent hardwired installation. Larger commercial spaces or expansive outdoor areas may need higher wattage models in the same series rather than the 1500W unit.
