We provide robust indirect oil‑fired heaters designed for safe, efficient, and reliable heating for a variety of industries and drying out programmes. The indirect system ensures that combustion gases are safely vented outside, providing clean, warm air without the risk of fumes, making them ideal for environments that require a controlled atmosphere. Our CLIMEX® indirect oil-fired heaters are portable, energy‑efficient, and capable of delivering powerful, consistent heat to maintain optimal working conditions, whether you're drying out materials, warming large spaces, protecting the health of workers, or ensuring equipment operates effectively in cold weather.
Our indirect oil-fired heaters have an integrated thermostat as standard, however you may prefer to upgrade to a wireless thermostat for a small additional cost. Please ask us for pricing when you book your heater.
Our indirect oil-fired heaters work by constantly heating large volumes of fresh air, which is then forced into a building via ducting. These units constantly displace the damp air in the building with fresh warm dry air from outside, thereby achieving regular air changes. This is a great way to achieve ventilation and heating all in one.
Yes, our indirect oil-fired heaters are built to perform in low temperatures, making them ideal for winter construction projects, drying out materials in cold environments, or ensuring that equipment operates effectively in freezing conditions.
The main advantages are clean, fume-free heat and the ability to safely operate in environments where air quality is important. Unlike direct heaters, indirect systems prevent the risk of harmful gases, making them ideal for sites where people are working in close proximity.
Yes, since the combustion gases are vented outside, our indirect oil-fired heaters ensure that the heated air inside remains clean and free from harmful fumes. They are designed to be safe for use in enclosed or controlled environments, with proper ventilation.
Our indirect oil-fired heaters are engineered for energy efficiency, providing consistent, powerful heat while minimising fuel consumption. This helps reduce running costs, especially when used for extended periods on large-scale projects. The heaters can also be run on Hydrotreated Vegetable Oil (HVO furl) which is a fossil-free, paraffinic fuel made from 100% renewable raw materials.
Yes, our CLIMEX® indirect oil-fired heaters are designed to be portable, allowing for easy transport and deployment on different sites or locations as needed. This flexibility makes them an ideal temporary heating solution.
Indirect oil-fired heaters are perfect for a variety of applications, including construction sites, industrial facilities, temporary heating for large spaces, drying out materials, and maintaining optimal working conditions during cold weather.
Indirect oil-fired heaters burn oil to produce heat, which is then transferred to a heat exchanger. The clean, heated air is pushed into the space, while the combustion gases are vented outside. This makes it ideal for use in environments where air quality is crucial.
An indirect oil-fired heater is a type of heating system that uses oil as a fuel source to generate heat, which is then transferred to the air or space being heated. The combustion gases are safely vented outside, ensuring the air remains clean and free from fumes.
Hydrotreated Vegetable Oil (HVO) is a fossil-free, paraffinic fuel made from 100% renewable raw materials. It is a sustainable, high quality fuel, suitable for use in most diesel powered machinery. HVO is cleaner than diesel and is FAME free. HVO is compatible with all RVT mobile indirect oil-fired heaters.
In the winter months, construction sites can quickly become waterlogged and the cold damp air prevents internal walls from drying; which in turn causes project delays. Without heating or drying-out equipment on site, you not only risk failing to meet project deadlines, but you also risk the health and well being of your staff. Cold and damp conditions can leave workers more susceptible to cold and flu, a sore throat, norovirus and asthma. Read more.
You require three elements to dry out a building effectively;
If you are drying out a damp building, in most cases an indirect oil-fired heater will be more effective than an electric heater. This is because the dry heat raises the room temperature and so lowers the relative humidity of the air, therefore allowing the air to absorb more water from surrounding surfaces. The constant air movement also ensures that plaster dries evenly, so that cracks and structural problems do not occur.
