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.
