Model LK Series - Domestic Water Coils
From Heat Exchanger
The domestic water coil is a heat exchanger which can also be used to harness the energy in the hot water accumulator tank containing mass water for heating domestic water. A separate domestic water accumulator tank is not needed; instead, the same accumulator tank can be used to transfer thermal energy both for heating domestic water as well as the floor or radiator heating system. The size of the domestic water coil depends on the temperature of the accumulator tank and the need for domestic hot water. In the accumulator tank design phase, separate large needs for domestic water must also be taken into account, such as whirlpool bathtubs, swimming pools, or sauna facilities with several showers. We are happy to offer assistance in choosing the correct coil size so that the end result offers a solution that is optimised individually for each customer and provides thermal energy for every need.
Domestic water coils in standard sizes are presented in the table below. The material is Ø 22 mm Cu finned copper, but other material options are also available. The heat transfer characteristics of finned copper as a material are better than stainless steel, which means that the surface area does not need to be as large.
