Thermolier Unit Heater (Electric)

From: £680.00 ex VAT

The heavy duty Electric Thermolier Fan Heater is a high capacity electric unit heater with a powerful fan, producing a high-volume airflow which distributes the heat generated evenly and effectively around the environment in which they are installed. Units are designed for vertical or horizontal mounting and air discharge.

Ideal for space heating in larger areas such as factories, warehouses, workshops, sports halls and open plan stores and for anti-condensation heating in plant rooms.

High ceiling locations inevitably benefit from Thermolier as part of an effective heating solution. Easy to install and control, features include improved air circulation, moisture resistance and no need for wall space.

Product Description

Thermolier Unit Heaters are part of a fan driven hot air heating system which utilises efficient heat transfer technology to keep cost at bay. Traditionally, units have been available for use with steam or hot water. Turnbull & Scott are now pleased to announce that in response to changing requirements and customer demand the Thermolier family has been extended to include an Electric Thermolier.

Electric heating is 100% efficient at the point of use. With the drive to Net Zero Emissions and the corresponding increase in low-carbon electricity generation in the UK, the Electric Thermolier Fan Heater is ideally positioned to help you keep your large spaces heated while delivering on your low carbon strategy.

Front louvers and careful siting of the units gives exceptionally fast warm up and practical heat control in large spaces and the fact that the units require little or no maintenance gives a clear indication of their ruggedness and efficiency.

Key Features

  • Electrically powered – supporting the drive towards Net Zero
  • Unique aerodynamic design features optimise heat transfer & minimise airflow resistance resulting in high efficiency
  • Rugged heavy duty finned metal sheathed elements
  • Totally enclosed permanently lubricated motor for increased reliability
  • Automatic reset over temperature cut out for added safety
  • Fan delay switch to purge unit of residual heat on switch off
  • Draw through design for efficient air circulation
  • Adjustable directional louvres for optimum airflow
  • Flexibility of horizontal or vertical mounting

N.B. It should be noted that unit heaters, such as this, are ‘space heaters’ and as such are designed to spread heat across an entire space and are not “spot” heaters that are designed to heat a small occupied area within a larger space. (See our Electric Infrared Heaters for localised heating).

Design & Installation

Once the total heating load of the building is calculated, the quantity and capacity of the unit heaters must be determined. A large number of low-capacity heaters provides more uniform heat distribution. This is recommended when the area will be occupied by a relatively large number of sedentary personnel, (i.e. working on production lines and at benches).

A large number of smaller capacity unit heaters tends to prevent hot drafts, reduces noise levels, and increases diversity of load to help reduce electrical demand and operating costs.

In warehouses where even heat distribution and constant temperatures are less important, a smaller number of high capacity units can be used – in many cases reducing installation cost. To maintain reasonable heat distribution and reduce severe stratification, even in lower bay areas, the total air volume of the space should pass through the unit heaters about three times per hour.

It is important that the rated voltage of the heating equipment matches the supply voltage. Supply voltage in excess of the heater rated voltage can damage equipment. Supply voltage lower than the rated heater voltage will decrease heater output as well as run the risk of damaging some components.

All electric unit heaters are shipped fully assembled. Heaters may be mounted in the horizontal or vertical air discharge configuration using factory supplied mounting equipment or using special hardware facilities supplied by others. The wall and/or ceiling structure must be sufficient to support the combined weight of the heater and any mounting bracket and accessories.
