Need to cut the cost of heating your large commercial or industrial space? Thermolier fan-driven hot air heating systems are ideal if you need to heat premises with a high ceiling, where heat tends to collect in the rafters, rather than where it’s needed down below.

Thermolier fan heaters from Turnbull & Scott use heat exchange technology with gills for efficient heat transfer and fans to circulate the heated air, avoiding temperature extremes which can be detrimental to products, staff and your heating bills. The heaters are extremely robust, requiring little or no maintenance, and come with a three year guarantee, giving you complete peace of mind.

Flexible bespoke heating for large spaces

Our engineers design Thermolier unit heaters to suit your exact specification, with precise wattage outputs for your space, to cut heating costs and wastage. The units are available in horizontal and vertical (downflow) models and with adjustable front louvres, giving exceptionally fast warm up and practical heat control.

Thermolier industrial space heaters are available for use with steam or hot water, and can run off LPHW, steam or gas from your existing gas, oil or biomass boiler. They are particularly ideal for commercial and industrial buildings, including warehouses, drying rooms, factories, swimming pools and loading doors. What’s more, they’re wall-mounted, so you don’t have to sacrifice valuable storage and production space.

With a Thermolier space heater, you’re benefiting from our 80 years of engineering experience, and build quality and reliability that’s second to none. See our brochure for full details of features and benefits, and click for our quality assurance and accreditations.
