Parameters and specification
|
Item description:
Latento reaches an excellent level of stratification in its accumulation tank because water with wax do not move - they are not whirled by pumps or water flow. Stratification means formation of water layers by temperature inside an accumulation tank. If traditional sources like wood, coal, gas or electric energy are used for space heating and DHW heating, stratification is not much important. Efficiency of such boilers does not change with the temperature of the heated liquid. On the other hand, renewable energy sources like solar collectors, a heat pump or up-to date gas boilers show better efficiency when heating colder liquid. Heat from renewable sources warms up the bottom part of the tank where the temperature is low. Thanks to that, renewable sources are used with better efficiency and more heat gained.

More energy from the Sun
The Solar heat exchanger is placed in the lowest, coldest section of the tank so collectors work with the highest possible efficiency. Heated water flows into the highest section of the tank and the tank starts warming up from the top. It is not necessary to wait until the tank warms up completely, after only 30 minutes of sunshine domestic hot water is available.
Excellent thermal insulation
The tank is made of polypropylene, with rigid foam insulation of excellent heat insulation properties. Unlike traditional accumulation tanks, Latento needs no additional insulation. In a tank with 95°C hot water, even after 8-10 days of no withdrawal the temperature sinks to 70°C only. A further temperature decline in a cooler tank is even much slower. So the heat losses are really minimized.
Fresh domestic hot water
Domestic hot water is heated instantaneously, in a stainless-steel heat exchanger made of a flexible pipe. It is first lead through the bottom part of the tank where water is preheated and cools down the bottom section of the tank. Since the solar heat exchanger is placed inside the bottom section, solar collectors work under a lower temperature and so with a higher efficiency. The flexible pipe then goes on into the upper section of the tank where water is afterheated. This means that domestic hot water is always fresh, no Legionella bacteria. In a stainless-steel heat exchanger usually no formation of scale occurs, and no sludge and rust can be found in hot water.
Easy placement and installation
A low weight (116 kg) and two handles enable easy handling. Its washable surface and a square footprint enable placing the tank anywhere in a house, it can pass even through an 80cm wide door. All outlets are concentrated on its top so the tank can be placed even in a limited space. Latento can stand next to a wall or in a corner. The assembly is very easy and fast.
Low costs of operation and maintenance
Latento cannot suffer from corrosion, that‘s why it can stay in service for all your life. The tank is maintenance- and trouble-free, and when the heating system needs renewal, Latento can simply remain in service. 5 years warranty.
