EZ-HEAT 1,500 Watt Baseboard Heater
The EZ-HEAT baseboard unit is a convection-style heater designed for medium-sized rooms and narrow installation spaces like crawl space perimeters. It provides steady, passive heat along its length instead of a fan-driven blast, which can be useful where dust circulation is a concern.
Features listed include an adjustable thermostat, two heat settings, overheat protection, a tip-over switch, and a stay-cool body. This combination supports continuous, quiet operation and reduces the risk of surface burns during routine access. The unit’s dent-proof end panels are intended for areas where tools or storage may be nearby.
For crawl spaces, baseboard heaters are often chosen for their low profile, ability to run for sustained periods, and even distribution. Consider mounting location, local code for fixed electric heaters, and wiring needs when planning installation.
Dura Heat EUH1465 Forced Air Heater

This Dura Heat unit is a 1500W forced-air heater with a pivoting base, aimed at quickly delivering warm air to a targeted zone. Its PTC ceramic element provides rapid heat-up and consistent output, making it suitable for bringing a crawl space above freezing during cold snaps.
The product emphasizes rugged steel construction, useful in utility areas where impact or debris are possible. It offers heat and fan-only settings for flexibility and can be directed with the pivoting base. The forced-air design creates airflow that may assist in reducing localized cold pockets but can stir dust in unsealed crawl spaces.
Because of its steel body and compact footprint, the heater can be placed on a stable surface away from insulation and combustible materials. Verify clearance requirements and moisture exposure in your crawl space before use.
BEYOND HEAT Milkhouse Space Heater
The BEYOND HEAT Milkhouse is a compact electric heater offering three power levels (fan-only, 1300W, 1500W) and an anti-freeze setting that activates below 40°F. The anti-freeze feature is specifically relevant to crawl spaces where occasional low temperatures risk frozen pipes or structural stress.
Safety is highlighted with a tip-over switch and internal overheat protection. The unit is ETL certified and constructed with heavy-duty materials. Its size and control options allow targeted heating near vulnerable equipment or pipes without heating the entire building.

Its portability makes placement flexible, but ensure the heater is elevated or secured to meet crawl space clearance and moisture considerations. Use in areas with adequate ventilation and dry conditions per manufacturer guidance.
Emerson SH1501 Electric Space Heater
The Emerson SH1501 features advanced PTC ceramic heating for fast warm-up and an efficient fan to distribute heat. It offers three heat levels
This model aims for balanced heat distribution and energy efficiency. For crawl space applications, the fan mode can help move warm air into corners, but it may also move dust if the crawl space is unfinished. The heater’s compact design supports placement near pipes or junctions that require supplemental warmth.
Confirm electrical circuit capacity in the area and maintain recommended clearance from insulation and flammable materials when installing portable units in enclosed spaces.
GiveBest Portable Electric Space Heater
The GiveBest heater is a compact ceramic fan heater with two heat levels
Safety features include flame-retardant materialstip-over protection. These protections are particularly useful in crawl spaces where access is limited and accidental disturbance could occur. The thermostat range supports freeze-prevention operation when set to a minimal maintenance temperature.
As with other portable heaters, ensure the unit is positioned on a stable, dry surface and that electrical connections meet local codes for damp or confined spaces.
Buying Guide: Choosing An Electric Heater For Crawl Spaces
Selecting the right heater for a crawl space involves safety, heat distribution, installation logistics, and electrical capacity. Below are key considerations to guide a practical choice.
Heat Type: Convection vs Forced-Air vs Baseboard
- Baseboard / Convection Heaters (like the EZ-HEAT) deliver gentle, sustained heat that warms surfaces and air by natural circulation. They are quiet and less likely to stir dust—good for long-term freeze prevention.
- Forced-Air / Fan Heaters (Dura Heat, Emerson, GiveBest) provide rapid warm-up and targeted air movement. Useful for quick thawing or spot heating but can move dust and humidity.
- Portable Ceramic Heaters (BEYOND HEAT, GiveBest) combine portability with PTC elements for stable output and built-in safety features; ideal for supplementing heat in specific crawl space zones.
Safety Features
- Tip-Over Protection is essential in low-access areas where movement or rodents may disturb a unit.
- Overheat Shutoff protects against internal failures and overheated surfaces near insulation or stored items.
- ETL/UL Certification indicates independent safety testing; prefer certified models for unattended or long-term operation.
Anti-Freeze Or Low-Temperature Settings
Heaters with an anti-freeze or low-temperature activation prevent periodic deep discharge by turning on automatically when temperatures drop below a threshold. This is particularly useful if the crawl space must remain above freezing while minimizing runtime.
Installation And Mounting
- Fixed baseboard units may require wiring and mounting; consult local electrical codes and consider a licensed electrician for permanent installation.
- Portable units should be placed on stable, non-combustible surfaces and away from insulation, vapor barriers, and stored items.
- Verify required clearances: some heaters need several inches of free area above or around the unit.
Moisture And Ventilation
Crawl spaces often have elevated humidity. Electric heaters are generally safer than combustion heaters in enclosed, low-ventilation spaces, but moisture can degrade components. Address drainage, vapor barriers, and ventilation before relying solely on a heater.
Electrical Requirements
- Most selected units are 1500W, commonly requiring a dedicated 15A circuit for continuous use. Check circuit load and avoid overloading shared circuits.
- Hardwired baseboard heaters may require 20A or 240V circuits depending on model—verify product specifications and local code compliance.
Coverage And Placement
Estimate the crawl space volume and local heat loss. Baseboard or fixed heaters are better for evenly heating along a perimeter, while targeted forced-air or portable heaters work for localized problem areas like near plumbing or foundation seams.
Maintenance And Durability
- Choose units with sturdy housings (steel or heavy-duty plastics) if the crawl space is used for storage or has occasional traffic.
- Periodic inspection for dust, rodent nests, and moisture intrusion extends service life and maintains safety systems.
Comparison Perspectives
- Safety-Focused: Prefer models with multiple automatic protections and ETL listing (e.g., BEYOND HEAT, GiveBest).
- Continuous Heat: Baseboard units (EZ-HEAT) offer low-noise, even output for long-term freeze prevention.
- Quick Response: Forced-air and PTC ceramic models (Dura Heat, Emerson) provide fast warm-up for urgent thawing needs.
- Portability: Compact heaters are easy to place or remove seasonally but require stable positioning and regular checks.
When selecting a crawl space heater, balance the need for continuous freeze protection, safety certifications, installation complexity, and the specific environmental conditions of your crawl space. Always consult product documentation and local codes before installation and consider professional installation for permanent units.
