Water To Air Heat Exchanger Explained

A water-to-air heat exchanger transfers heat from water to air. People often mistake these for car radiators. The hot water passes through copper tubes with metal fins attached. Tubes and fins are heated by circulating hot water from the boiler. To provide warmth, a blower fan turns on and blows air through the fins and tubes.

In forced air ducts, water-to-air heat exchangers are most commonly used. The drawing below illustrates this. The heat exchangers are usually installed above the forced air furnace plenum. These are available in several sizes, and are often installed by attaching "L-Brackets" to the inside of the plenum on which the heat exchanger rests in a "flat" orientation.

Technology To maximise heat transfer between water and air, tube coils are accompanied by aluminium fins. The air-to-water heat exchanger is enclosed in a metal frame to reinforce its structure. The hot water or other suitable solution enters the supply manifold of the water to air heat exchanger and is separated into coils, which carry it throughout the heat Heat exchanger to return heat exchanger. 

The most common types of these units are used for forced air heating and cooling systems, such as wood furnaces, boilers, stoves, and many others. ALFA water-to-air heat exchangers are also suitable for liquid cooling, as well as for a variety of liquid-to-air and liquid-to-liquid heat transfer applications. Aluminium is used as the fin material because of its high heat conductivity. The fin density is an impressive 12 fins per inch. It has a unique design that allows for heating loads of 50,000 to 60,000 Btu per square foot. Despite the high fin density, the flow resistance through the coils is surprisingly low.
