• In 2 models 100.1 and 125.1 in Energy efficiency class A
• Input and output for all media in the upper lid for easier connection to a wall-mounted gas boiler
• Heaters suitable for installation under wall-mounted boilers
• Preparation of DHW in buildings with a gas boiler
• The heaters have a fitted drain valve

A stationary hot water storage tank with side flange and heat exchanger, suitable for different heat sources; it can also be installed with a heating element.

• Available as the models 200, 250 and 300.
• The exchanger heats the water only in the upper part of the tank; the lower part stores the energy from the photovoltaic plant.
• The upper exchanger allows the water to be reheated using an existing heat source (gas, solid fuel or biomass boiler).
• Option to install heating unit.

Stationary combined storage tank suitable for connection to heat pumps and other low-temperature sources. In the upper part of the heater there is an enamelled water heater with a heat exchanger, and in the lower part there is an equalizing storage tank for the heating circuit.

• Space-saving design.
• Energy efficiency class “B” for model OKC 300 NTR/HR 100.
• Heat exchanger for a heat pump or a low-temperature source.
• Possible installation of heating flange unit.

Compact electric water heater suitable for one or more draw-off points.

• In a capacity of 20 l.
• Pressure enamel vessel.
• 2,2 kW heating element.
• The heater is powerful enough for a shower or multiple sinks.
• Multiple draw-off points can be connected in a pressurized system.

Function of storage tanks NAD and NADO

Storage tanks are used to accumulate spare heat from its source.

Source can be:

• Central heating with solid fuel
• Solar system
• Stoves with heat exchangers
• Heat pump system etc.

Some storage tanks enable combining more sources of energy.

Storage tanks type NAD serve only to storage spare heat in the heating system. Type NADO allows also direct heating of hot water (HW) in inner enamel vessel or its pre-heating for another water heater.

Everything depends on temperature of heating water, which is stored in the tank. Solid fuel heating system in most cases allows direct heating of HW in inner vessel up to desired temperature, but solar or heat pump system will only pre-heat HW and it is necessary to place into the system a water heater or install a heating unit into storage tank, for example an electrical heating unit from TJ G 6/4" series or a heating flange from TPK series, to have HW at required temperature.

Storage tanks types NAD and NADO combined with a boiler with solid fuel assure optimal operation of the boiler at ideal temperature.

All accumulaiton tanks are sold together with insulation.

Accessories for accumulation tanks are: a TPK flange heating unit and a TJ 6/4'' screw-in electric heating unit.
