Storage tank - Dalatanken

The Dalatanken is a storage tank for storing the heat energy generated from, for example, solar or geothermal energy, or burning pellets, wood, oil or electricity. The storage tanks are available as insulated or non-insulated versions, as well as in different colours and with volumes ranging from 500-7000 litres.

Our storage tanks are named according to their capacity and number of coils. A solar storage tank with a capacity of 750 litres and three coils will, therefore, be designated as 750-3. A buffer tank with the same capacity is thus a 750-0.

The construction, length and placement of the coils are important factors in achieving as efficient a heat exchange from the solar energy as possible.

Dalatanken - 0 coils (buffer tank)

The buffer tank is an energy storage tank that contains no coils and has connections for another heat source or to run in parallel with a solar tank. The buffer tank has four sockets for connecting to a heat source or other storage tanks and three sockets for thermometers.

Dalatanken - 1 coil

The coil in the single coil tank is normally located in the storage tanks top. The storage tank is intended to be used for moderate hot water use. It has connections for bivalent bypass valves and another heat source, as well as sockets for an electric heating element, sensors and thermometers.

Dalatanken - 2 coils

The 2 coil tank has a fore coil deep in the accumulator tank and a top coil in the upper part of the accumulator tank. The tank is suitable for properties with a significant need for hot water and is often connected to a buffer tank to increase the total capacity, for example, when burning wood logs. The accumulator tank has connections for a bivalent bypass valve, electric heating element, sensors and thermometers.

Dalatanken - 3 coils (solar tank)

Our solar tank is designed to provide the optimal exchange between domestic hot water and heat from the sun. This has been achieved through the use of three extended gilled tube coils (two for domestic hot water and one for solar heating) placed in the solar tank according to the latest research results. The solar tank has connections for a bivalent bypass valve and another heat source, as well as sockets for an electric heating element, sensors and thermometers.
NB! The construction, length and placement are important factors in achieving the most efficient solar heat exchange possible.

Dalatanken - 4 coils (4 coil solar tank)

The 4 coil tank has four gilled tube coils, (two for solar energy and two for hot water). The solar tank has connections for a bivalent bypass valve and another heat source, wood, pellet or oil boiler or other heat pump, as well as sockets for an electric heating element and three thermometers.

The extra, fourth solar energy coil mounted in the upper part of the solar tank enables much faster usable heat from your solar energy, as it is used to start warming up only the top of the solar tank. Once that part of the tank is warmed up, the solar energy then proceeds to heat up the rest of the solar tank by the lower coil.

All our accumulator tanks are available with the 4 coil option. This technology is at its best in accumulator tanks with larger capacities, where it takes time for the sun to heat up the water in the tank to the required temperature, as well as having a significant storage capacity.
