Ideal for well-ventilated areas like construction sites, warehouses and factories, our range of direct gas fired commercial portable and fixed heaters can generate large volumes of instant heat. With additional accessories, heat large or targeted areas effectively. Enquire below and speak to an expert today.
In addition to direct gas fired heaters, we manufacture and supply various types and sizes of commercial heaters which are designed for numerous applications and industries.
This includes direct oil fired air heaters, indirect fuel fired air heaters, indirect oil fired air heaters and infrared oil fired heaters, as well as electric heaters, infrared heat panels and commercial tent heaters.
Throughout the year, but especially in the colder months, a reliable, consistent way to generate warm air is vital to keep workers productive and protect temperature-sensitive applications. Direct gas-fired heating is a high-efficiency, cost-effective way to deliver much-needed heat to well-ventilated areas.
Useful across many industrial and commercial environments, our range of direct-fired heating systems are engineered to generate exceptional heating power in all circumstances, whether you are looking after peoples’ comfort or keeping equipment running optimally.
A direct-fired gas heater warms cold air by placing it in direct contact with an open flame, with hot air being produced at the other end. Due to this contact with the flame, the vast majority of the fuel used is converted into useful heat energy, delivering close to 100% fuel efficiency.
Other benefits of our direct-fired heating units include:
However, it is important that direct gas-fired heaters are only used in well-ventilated spaces when there are people or animals present. This is because exposure to an open flame means the heat output will contain by-products of combustion, such as CO2 and water molecules.
Gas-fired heaters also offer a number of benefits over oil-fired equivalents, including:
Our range includes both portable heaters, capable of providing instantaneous heat to any area with minimal setup, and fixed heaters, which are well-suited for areas with high air flow requirements, such as greenhouses, animal housing and workshops.
All our heating solutions are designed through our decades of experience, with a firm focus on energy-efficiency, sustainability and reliability in all environments.
Every solution we deliver starts with a bespoke consultation. Our highly trained experts work to understand your unique requirements so you receive exactly what you need.
Manufactured in-house by our specialist engineers, we tailor solutions that meet your expectations, and instantly connect you with the right supplier.

A direct gas-fired air heater is a heating device that uses natural gas, such as propane, to heat the air in a space. These are used in a wide range of industrial and commercial environments to deliver exceptional levels of warmth, whether this is to support people’s wellbeing, or keep equipment running optimally.
Direct-fired gas air heaters place cold air in direct contact with an open flame, generated by burning canister gases such as a propane-butane mixture. Hot air then flows out of the other end and into the space, warming the surrounding area.
This differs from indirect heaters, which use heat exchangers that contain the flame. This means the hot air produced is dry and does not feature byproducts of combustion, such as water and CO2.
One of the main benefits of a direct gas-fired air heater over an indirect heater is their ability to work at close to 100% efficiency. Because the air is in direct contact with the integral flame, these types of solutions are characterised by their high performance and low running costs.
Furthermore, in comparison to oil-fired heaters, gas-powered versions are typically:
However, it is important to note that direct gas-fired air heaters deliver moist hot air alongside products of combustion, meaning it is ineffective for drying materials. It also cannot be used in underground or compact environments for safety reasons.
The frequency of maintenance and service for a direct gas-fired air heater will depend on the specific unit, its application, and the environment you use it in. However, there are some usual staples when preparing your heaters for use:
It is also recommended to have units serviced and inspected at least once a year.
At Dantherm Group, we have servicing partners and spare parts dealers based across Europe to provide quick, specialist support whenever you need it. Reach out if you would like support with your units, or for express guidance on how to operate and look after your specific unit.
Yes, but within limits. Direct gas-fired air heaters can be used in both indoor or outdoor environments, depending on the specific unit’s capabilities.
However, when used indoors it is important that the space is well-ventilated. This is because the moisture and combustion products generated by these heaters could place the health of people or animals in the area at risk. Plus, this moisture could cause unintended water damage and mould growth in the space when the heaters are switched off.
Within direct-fired gas heaters, air is placed in direct contact with an open flame. This is incredibly efficient and makes the design of these units far simpler. However, the byproducts of combustion this produces limits where these heaters can be safely used, and makes it ineffective at certain applications (e.g. drying plaster).
By using a heat exchanger to house the flame instead, indirect-fired gas heaters ensure that all air generated is clean and dry, at the cost of slightly reduced efficiency and performance.
Through our decades of experience and expertise in all forms of heating systems, we will advise you on whether a direct or indirect-fired solution is best suited for your needs and parameters. We will guide you through your options, and immediately put you in touch with your local supplier.
Yes. Direct gas-fired heaters are close to 100% energy efficient as the hot air it generates comes in direct contact with an open flame.
