General information
Construction EcoEl
The picture below shows the fundamental construction of the product.
Fresh water connections
Here you connect the fresh
water connections of the
property. The cold water is
led down to the lower part of
the coil.
Gilled coil for hot water
The product is equipped with a well dimensioned
gilled coil in copper. The product is not supplied
with any parts which can rust and break. The
temperature can be kept low without risk of
legionella bacteria.
Bivalent mixing valve
The automatized mixing valve
ensures that an even heat
reaches the radiator system
continously. The valve has
double doors and first collects
the hot radiator water from the
water heated by the heating
pump.
Upper part
In the upper part of the coil the
water is heated to the selected
hot water temperature.
Immersion heaters
A built-in immersion heater
functions as peak heat if the
effective output is not sufficient
along with the rising of the hot
water temperature.
Lower part
In the lower part of the coil the
water is pre-heated by the heat
pump. The major part of the coil
is located in this part.

Note: Do not connect
the product accord-
ing to this construc-
tion sketch, see instead
the measurements on
page 30 and the chapter
”Plumbing system”.
Drainage valve
Used for drainage of the pro-
duct and/or radiator system.
When EcoEl connected to heat
pump, this would be the flow
pipe to the heat pump.
Insulation
The tank of the boiler is
insulated with die cast
polyurethane foam for
minimal heat losses.
Connection for heat pump
When EcoEl connected to heat
pump, this would be the flow
pipe from the heat pump.
