1. Description
Accumulation tanks serve accumulation of excessive heat from its source. You can use solid fuel boiler, heat pump,
solar collectors, fireplace insert, etc. as source. Some sorts tanks allow the combination and connection of more
sources.
The NADO type tanks serve only for accumulation of heat in the heating system and allow heating or preheating of
HSW (Hot Service Water) in an inner tank. Incorporation of an accumulation tank in the heating system with a solid
fuel boiler allows an ideal run of a boiler at favourable temperature during the boiler operation. The main benefit lies
in the period of optimum operation (i.e. with maximum efficiency) when the excessive unconsumed heat accumulates
in the tank.
The tanks and potential tubular exchangers are made of steel, without the inner surface treatment, the outer surface
of the tank is provided with a protective paint. The tanks are manufactured in 500, 700 and 1000-litre volumes.
Individual versions are additionally equipped with one or two tubular exchangers, each of 1.5 m2 area and an
inspection hole of 182 mm clearance with an option of installation of an in-built electric heating unit TPK.
The NADO type enables direct heating of HSW (Hot Service Water) in an inner enamelled tank, or preheating of water
for another water heater. Connection with boiler usually allows direct heating of HSW for required temperature inside
the inner tank, but connection to the solar collectors or heat pump only preheats
and it is necessary to place another electrical heater, which heats the water onto the requested temperature or to
mount additional electrical heater into the accumulation container, which is compatible with electrical heater unit TJ

or heating flange TPK.

3. Description of individual versions
NADO v1
Accumulation tank with a flange of 210 mm screw spacing. The flange can be used for assembly of an in-built electric
heating TPK flange unit. In the standard version, the flange is blinded. Funnel G6/4“ can be used for fitting an electric
heating unit TJ G 6/4“ for accumulation tanks NADO 140v1. The tank contains an inner enamelled accumulator of 140
or 200 litres.
NADO v2
Accumulation tank with a flange of 210 mm screw spacing for the assembly of an in-built electric flange heating unit
TPK and one exchanger of 1.5 m2 area for connection of an additional heating system (e.g. SOLAR). In the standard
version, the flange is blinded. Funnel G6/4“ can be used for fitting an electric heating unit TJ G 6/4“. The tank contains
an inner enamelled accumulator of 140 litre capacity.
NADO v3
Accumulation tank with a flange of 210 mm screw spacing for the assembly of an in-built flange electric heating unit
TPK and two exchangers, either of 1.5 m2 area for connection of an additional heating system (e.g. SOLAR). In the
standard version, the flange is blinded. The tank contains an inner enamelled accumulator of 100 litre capacity.
