Review of the best according to the editorial board. On the selection criteria. This material is subjective and does not constitute advertising and does not serve as a purchase guide. Before buying, you need to consult with a specialist.
Heat guns of direct heating do not have a heat exchanger and chimney – in them the heat released from the combustion of fuel in the chamber is immediately transferred to the room. On the one hand, this requires enhanced ventilation, but on the other hand, it contributes to an efficiency close to 100%, while for indirect heating heaters this figure reaches 82%.
Direct heating guns are useful for drying plaster, putty and other materials during finishing work. They can also help create comfortable temperature conditions on a construction site, where there is a roof and windows have already been installed. Sometimes they are heated in workshops or large boxes, as well as at enterprises. When choosing a direct heating gun, it is important to know what their types and features are. It is useful to read customer reviews. All this is in our review of the best models, which will show the pros and cons of popular products in this category.

The best direct-fired gas heat guns
Compared to diesel cannons, gas-type heat heaters burn fuel better. This requires less ventilation, which helps to retain more heat in the room. Gas cannons are also powerful enough. But for the operation of direct heating equipment, you will need a gas main or a cylinder, as well as an electrical network to power the fan and the piezo ignition system. This is the best option for heating workshops, boxes, enterprises or greenhouses.
In the first place in the category of direct fired gas cannons is the model from “Ballu” with a power of 75 kW. Product dimensions are 270x420x810 mm and weighs 14 kg. The device is endowed with mechanical control and will need to be connected to a 220 V power supply. The gun burns more than 6 liters of gas per hour. The heater is powered by a liquefied propane-butane mixture supplied in cylinders. The kit already includes a reducer and a connection hose. The gas heater is started by pressing one button. There is a handle in the upper part of the case to move the device. In the reviews, buyers are satisfied with the high-quality assembly and a durable casing that tolerates frequent transportation.
This heating model with direct heating technology is the leader in performance among gas installations. The gun blows out 2000 m³ of hot air per hour. At the same time, the heating power can be adjusted by smoothly changing the power from 22 to 75 kW, which makes it possible to adapt the gun for rooms with different areas.

It consumes 2.6 liters of gas per hour at a pressure of 0.75-1.5 bar and delivers power from 18000 to 33000 W, which is regulated by a separate toggle switch. The design already has its own thermostat to maintain the set temperature. The flame is ignited by an electronic system. In case of overheating, the direct-acting unit turns off automatically. The double solenoid valve provides increased protection against gas leakage, which owners like in reviews. During operation, the ionization electrode monitors the presence of a flame and cuts off the gas if the fire is extinguished. When the thermal effect is turned off, the fan continues to run for some time to cool the combustion chamber. After turning off the device, it can be packed and transported – it is safe and will not damage the contacting materials.
The heat gun is notable for the possibility of connecting a room thermostat, for which a separate socket is displayed.

Best Direct Fired Electric Heat Guns
Electric guns create direct heating from the heating element and the fan. They only need to be connected to a 220 or 380 V network. In terms of dimensions, such equipment is more compact and does not emit harmful gases, so the room does not need to be frequently ventilated. But electrical devices are inferior to the above categories in terms of power, therefore they are suitable for small halls and rooms. This is the best option for faster drying of walls in home renovations, workshop or garage heating.
In the first place is a cannon with an electric heating element, generating up to 820 m³ of warm air per hour. The functionality allows you to set the power in steps of 6 or 9 kW, as well as smoothly regulate the temperature. The direct heater will turn on and off automatically when the set value is reached. A cylinder with a fan and a heating element is placed inside a tubular frame with two handles, which is convenient for transportation. If the device overheats, it will turn itself off and turn it on again only after it has cooled down. The gun weighs 11 kg and has dimensions of 380x260x380 mm. The structure consists of double walls, which increases its rigidity and resistance to thermal deformation.
It is one of the most powerful direct fired electric heat guns, producing 9 kW, which is quite impressive for this category. To power it, you need a three-phase network with a voltage of 380 V. If you need to heat an area up to 100 m² with electricity, then definitely choose this option.
