What is the best 240V electric heater? Commercial and industrial heaters have a complex design as they should provide sufficient reliability in combination with power and heating efficiency. Besides, the advanced and extra powerful models shall be obligatory checked for compliance with this field's commonly accepted safety and quality standards. Thus, reliability and durability are the most crucial features of the 240V electric garage heaters. The appearance and noise level are less relevant.

240V electric garage heaters

Heating large workspaces, basements, or garages require a lot of effort from their owners in terms of picking up the appropriate alternatives and spending incredible sums of money on energy-consuming heating beasts. Thus, if you belong to the holders of the larger space, it is better to focus on a powerful 240V electric heater. The latter will be a valuable and durable option. Below, you will learn about the peculiarities of the advanced professional-grade 240V units. Using such equipment for heating commercial and industrial facilities and home-based large working areas will lead to considerable savings related to maintenance of the required temperature indoors and outdoors.

Types of the electric heaters 240V

  • Fan heaters. These devices are considered the most compact among other models reviewed in this guide. Due to the compactness and fast heating up, the fan heating models are widely used in office buildings, stores, and other commercial and industrial premises. There are two types of fan heaters: spiral or ceramic heating elements. The latter is a more energy-efficient option and prevents excessive air drying. The downside is related to the latter, as running these models for extended periods is not recommended. Being close to a running fan heater for a long time may cause skin dryness and even headache.

  • Blow heaters. These units are similar to fan heaters but equipped with more powerful heating elements and fans. They are deemed one of the best heaters for large garages, industrial facilities, and other big floor workspaces. However, you should be ready to pay considerably more money for operating such units due to the high energy consumption. I personally wouldn’t recommend using the blow heaters at home. However, these models are offered for running on 240V and 120V supplies. 
  • Infrared heaters. It is the most versatile option among other heating models due to the possibility of indoor and outdoor usage. It heats the spotted objects instead of the surrounding air, which is the conceptual difference of the infrared devices from other counterparts. An integrated metal reflector behind the heating element contributes to the quick temperature rise and warming of the neighboring objects. The body of the heater still stays relatively cold. The heating space depends on the heater size and the type of heating element. Commonly these units are installed outside for heating the open-air cafes, patios, any outdoor workspaces, checkout zones at the stores, etc. I believe infrared heaters are more suitable for commercial and outdoor use. Not everyone would be OK with a spot scorching light in household use.

  • Convectors. It is a comparatively new electric heater rapidly gaining popularity among customers in many spheres. Initially, they were designed for home-based applications, heating small areas, like living rooms or bathrooms, etc. However, the modern upgraded models can tackle any spacious heating issue.

Its design and the principle of operation are pretty simple. In particular, the convector consists of a spiral heating element closed by a metal casing. It works by heating the ambient air, which is sucked from the bottom and rises through the upper slots that are already hot. Besides, many advanced convectors are equipped with a timer and an auto thermostat. The STIEBEL ELTRON CNS 300 may boast even a more comprehensive set of advanced functions.

What should you know about 240V electric heaters to make the right choice? | Buyers’ Guide

  • Power output. It is the main parameter when selecting an electric heater. This parameter influences the time for heating the space to the required temperature. The more power is, the less time it will need to reach the set temperature. Modern electric heaters of up to 4 kW are the standard domestic units that can run on a standard one-phase 120V power outlet. The devices of 4 kW and higher belong to commercial- and industrial-grade equipment. They must be plugged into a three-phase power supply to ensure a stable operation. The commercial and industrial premises have larger spaces. Consequently, purchasing a smaller number of more powerful heaters for such purposes would be more reasonable.

  • Wattage control. Different models feature from 1 up to 4 heating modes. Thus, an optimum power range may be selected based on your needs and the desired temperature. This function enables efficient heating and allows reducing energy consumption. Taking into consideration that 240V units are potent due to the higher energy consumption, this function would be handy, indeed.

  • The difference between 240V and 120V. The more powerful electric heaters run on 240V and are commonly used for heating large commercial and industrial areas like supermarkets, construction sites, auto service centers, garages, and other workspaces. The high energy consumption resulting in higher bills is the main disadvantage of such thermal sources. Also, a 240V device will consume equal to its power in kW and operate loudly compared to the 120V counterparts. Consequently, you should weigh up all pros and cons to decide which option will suit your needs. If you are looking for a home-based appliance, choose one of the modern 120V options which will deliver enough warmth to heat your living rooms, basement, or garage.

Types of heating elements

  • Fan and blow heaters are equipped with electric coils or ceramic elements. The latter is preferable due to the higher energy efficiency. Besides, they do not overdry the air and enhance the uniformity of air distribution.
  • Convectors feature several types of tape-and-needle, tubular and solid heating elements. The tape-and-needle is the cheapest but too fragile option. However, it is capable of rapid heating up and cooling down. Tubular elements are very reliable and durable in operation. Nevertheless, you may hear a strange sound that reminds cracking right after its switches to the ON position. The solid alternatives are noiseless when running and demonstrate a minimum heat loss.
  • Infrared heaters may be equipped with different types of heating elements. The halogen is a big lamp with a tungsten wire. Such an element has a sufficient heating distribution. However, it emits short infrared waves, which are the most harmful to health. The quartz tubes can heat up quickly. However, due to a high thermal load, they serve from 2 to 3 years only. Besides, its red light may irritate the eyes. The carbonic heating elements are very reliable and safe. Thus, such heaters are commonly used in medical institutions or saunas where special care must be taken regarding safety issues. However, they are the most expensive among other counterparts in this class.
