AKVA hot water coils

The domestic hot water coil is a heat exchanger, which can be used to harness the energy of a hot water tank containing pulp water for domestic hot water heating. There is no need for a separate hot water tank, but heating energy can be transferred from the same tank to both domestic hot water heating and the floor or radiator heating network. The size of the hot water coil depends on the tank temperature and the hot water demand. Separate large hot water needs, such as hot tubs, swimming pools or sauna facilities with several showers, must also be taken into account in the planning phase of the book. We are happy to offer helical sizing assistance so that the end product offers each customer an individually optimized solution and thermal energy for all needs.

The standard hot water coils are presented in the table below. The material is Ø22 mm Cu comb copper, but other material options are also available.
Combed copper has better heat transfer properties than RST material, so the surface area does not have to be equal.
