Commercial Heating Installation for Every Business
Large industrial premises need heating systems capable of handling significant floor space, high ceilings and constant use, which is exactly where our expertise comes in. Oltec provides specialist industrial heating installation services designed to improve comfort, efficiency and running costs for factories, warehouses and production facilities throughout Sunderland. We also deliver commercial heating installation for retail units, offices, garden centres, gyms and showrooms, ensuring customer-facing businesses benefit from consistent, reliable warmth. Each installation begins with a thorough assessment of the premises, allowing us to identify the most appropriate heating technology and configuration for the space. Our team considers factors such as building usage, occupancy levels and existing infrastructure to design a system that delivers genuine long-term value. With over 40 years of industry experience, we understand what it takes to install heating systems that withstand demanding industrial conditions while remaining efficient and cost effective to run.
Warm Air Heating Systems for Warehouses and Factories
Large open plan buildings benefit significantly from warm air heating systems, which provide rapid, efficient heat distribution without the limitations of traditional radiator setups. Oltec Services specialises in installing warm air heating for warehouses, factories, workshops and showrooms throughout Sunderland, helping businesses maintain comfortable temperatures even in high ceiling environments. Our expertise extends to factory heaters, warehouse heating and dedicated workshop heating solutions, each designed to suit the specific demands of industrial premises. We also provide garage heating, sports hall heating solutions and reliable hot water systems for holiday parks, covering a broad range of specialist applications. Warm air heating is especially effective in spaces with high levels of activity or frequent vehicle and pedestrian movement, where consistent heat retention can be challenging. Our engineers take a tailored approach to every installation, considering building size, usage patterns and insulation to ensure the system delivers genuine efficiency gains and long-term cost savings for your business.


Annual Heating Servicing and Planned Maintenance
Industrial heating systems require regular attention to remain safe, efficient and compliant with current regulations, which is where planned maintenance becomes essential. The Oltec Group delivers annual servicing and structured maintenance programmes for businesses throughout Sunderland, ensuring gas safety certification is renewed on schedule and your system meets all necessary standards. Routine servicing also helps fulfil building insurance obligations, as many providers require evidence of regular maintenance to keep policies valid and claims processable. Additionally, consistent servicing supports the integrity of manufacturer warranties, helping to protect your original investment over the long term. Our engineers carry out comprehensive checks during each visit, assessing performance, safety and efficiency to catch any developing issues early. This proactive maintenance approach reduces the risk of costly breakdowns and unplanned downtime, keeping your operation running without interruption. Whether managing a single site or multiple locations, our maintenance programmes are designed to keep your heating systems reliable, compliant and performing efficiently throughout every season.
Heating System Upgrades and Replacements
As heating systems age, they often become less efficient, more prone to faults and increasingly expensive to run, making upgrades a worthwhile investment. Oltec FM specialises in heating system upgrades and replacements for businesses throughout Sunderland, helping to improve both performance and energy efficiency across a range of applications. Our team regularly upgrades ageing factory heaters, modernises warehouse heating systems and replaces outdated garage heating with more efficient, reliable alternatives. We also support specialist requirements, including hot water systems for holiday parks, ensuring businesses across different sectors benefit from improved heating technology. A well planned upgrade can significantly reduce energy bills, improve temperature consistency and lower the likelihood of unexpected breakdowns. Our engineers begin every upgrade project with a detailed assessment of the existing system, identifying inefficiencies and recommending solutions that align with your budget and operational needs. From planning through to installation, we work efficiently to minimise downtime, ensuring your business continues operating smoothly throughout the upgrade.
