Water-supplied air heating

Indirectly fired air heating

With water-supplied air heating, also called indirectly fired heating, the air heater is heated by means of hot water supplied by a central heating boiler or heat pump. These unit heaters are also called LPHW (Low Pressure Hot Water) or LTHW (Low Temperature Hot Water) heaters. The hot water units are equipped with a heat exchanger that converts the hot water into warm air. It is then blown into the room via a powerful and energy-efficient fan.

The advantages of water-supplied air heaters

Water-supplied air heating has many advantages, such as comfortable heat and lower energy bills. In addition, the unit heaters are maintenance-friendly and low-noise. Compared to directly fired appliances, indirectly fired air heaters are often easier to install because no flue gas discharge is required.

Mark’s water-fed heating systems are available in many versions and an extensive capacity range. As a result, the air heaters have many applications, such as in showrooms, offices, shops, hospitals, changing rooms and industrial halls.

For industrial applications, Mark has the TANNER MDA in its range, the most versatile hot water air heater on the market. For rooms with low ceilings, we recommend the TANNER MBA or LDA SWIRL. These appliances have a limited height and can also be integrated in a system ceiling.
