A Commercial Heating Alternative

What is Therma35™?

Therma35™ is a cost-effective alternative to conventional gas oil for industrial heating applications. Meeting BS2869 Class D accreditation, Therma35™ heating oil can be used across a range of commercial boilers, dryers and heaters without compromising on output or performance.

Is it cost effective?

As well as being a cheaper alternative to conventional gas oil, Therma35™ industrial heating oil offers a range of added-value benefits. Unlike red diesel, the fuel’s long-term storage stability, winter-grade and zero bio content means it can be bought in bulk and stored all year round without the risk of spoilage, interruption or waxing.

Will it cause disruption?

For many businesses, one of the most significant barriers to implementing a new heating oil is the potential for disruption. Therma35™ can be added to existing tanks without having to empty them beforehand or make any modifications, enabling businesses to make the move to a more economical alternative with confidence and without interrupting heating provisions.
