Gas heating of DHW

 

Infinity continuous flow water heater prepares warm water of constant temperature, as needed at the moment. Despite its small dimensions and weight it reaches up to 44.5 kW output and is able to heat as much as 32 l/min. of water. Thanks to its huge regulation range, its min. output is only 3.5 kW and the heater works already from the flow rate of 2.7 l/min. Thanks to that, it can easily supply continuous hot water for a large house with several bathrooms and further outlet points. 

Infinity works with high efficiency and without any risk of Legionella bacteria. Unlike storage heaters, there is no thermal loss during periods of no DHW discharge.

For higher outputs, "Infinity's" can be joined into a cascade or manifold system. It's proper working configuration can be ensured simply by fitting special pressure-activated valves (PAM), or by means of an electronic control unit. Such a cascade starts heating the water even from a minimum 2.7-l/min flow and only the number of heaters limits its maximum capacity.

In order to cover peak DHW demand, a single heater or a heater cascade can work with a storage vessel enabling thus to cover short periods of peak demand higher than the installed capacity of heaters. Individual heaters or cascades can work with a DHW circulation pump.

The heater is in "turbo" execution, with a sealed combustion chamber, so it needs no chimney and requires only very little space. Thanks to the sealed combustion chamber, any danger of fume or gas leakage into living space is excluded.

The unit has no switches and no regulating elements. The heater is factory-preset to 55°C (can be changed to 40-75°C by an authorized serviceman); upon connecting a remote control (included in packing) the user can set the temperature between 37-55°C. Also remote units with voice output are available, enabling to select not only the temperature but also the desired volume of hot water supplied (e.g. you can select your bath volume and after filling the bathtub with water of the selected temperature to the preset volume, and the unit will advise you your bath is ready). You do not have to mix hot water with cold in a mixing valve, Infinity will supply DHW of the selected temperature.

Precise regulation of the output water temperature is ensured by a microprocessor control unit, even in periods of sudden flow fluctuations. It can manage even very low output thanks to not only the control unit but also a precise flow sensor, several temperature probes, continuously controlled DHW by-pass and continuously modulating burner with disconnectable sections. For obtaining high efficiency and ecological combustion, the output of fan supplying combustion air is continuously controlled - the control unit measures and takes into account even the temperature of the inlet air. 

 

  • cascade formation possible for reaching high outputs
  • suitable for both domestic and industrial usage
  • can work with a circulating pump
  • can be completed with a storage vessel to cover peak demand
  • remote controls enabling comfortable control
  • steady water temperature even in case of simultaneous demands from several taps

Accumulation tanks with phase change material

 

Latento accumulation tank utilizes the feature of a wax filling that makes it possible to store a big amount of heat at a constant temperature when wax changes from the solid to the liquid phase. While ordinary heat accumulation into water causes temperature increase, heat accumulates into wax at a permanently low temperature. Solar energy can be thus gained with higher efficiency and heat losses in such an accumulation tank are lower.

 

NO TRADEOFFS IN HEAT ACCUMULATION

  • Excellent insulation properties - a thick polyurethane insulation between plastic walls

  • Nice, light and safe execution - pressureless accumulation fluid

  • Easy handling - can be carried to the location even on stairs and through an 80cm door

  • Long, corrosion-free lifetime - copper and stainless-steel heat exchangers, resistant plastics

  • Increased accumulation ability thanks to the wax filling‘s latent heat

  • Perfect stratification thanks to the use of heat exchangers

  • Solar hot water just after 30 minutes of sunshine

Latento accumulation tank is designed for the best economy of the stored energy. Its excellent properties are obvious in additional solar heating and long-time accumulation. Solar energy can be either used immediately or stored for many days in the summer, and used for additional heating in the winter.

RENEWABLE ENERGY SOURCES

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 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 POSITIONING 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. Warranty 5 years

 

 

FINNED TUBE HEAT EXCHANGERS

They serve for heat transfer in accumulation tanks. They are made of finned copper tubes that offer larger tube surface and better heat transfer. They differ in the size of their heat transfer surfaces, in their length, connecting size, kind of winding and in the number of tubes. Upon agreement, in case of large quantities demanded, also tailor-made types can be manufactured.

Performance parameters of DV193 and DV285 plate heat exchangers

Performance of a heat exchanger changes with many factors, esp. with the difference between temperatures of fluids in the two circuits and with fluid type. That is why a heat exchanger performance cannot be presented without specifying its working conditions. Generally speaking, the higher the temperature difference between the primary and secondary sides and the higher the flows on both sides of the heat exchanger, the higher performance the heat exchanger shows. The higher temperature drop is designed for the heat exchanger, the smaller its needed heat exchange surface area is, which brings lower investment costs.
For applications with a solar system, heat pump or a condensing boiler, it is necessary to use a heat exchanger for a low  temperature drop (6 °C, max. 10 °C). Higher temperature drop means a higher working temperature of the solar system or  heat pump and its worse efficiency /COP.
For applications with a current gas boiler or a solid-fuel boiler, a heat exchanger for a higher temperature drop can be used (e.g. 20 °C or even more). This means a smaller and less costly one because the efficiency of the source does not drop with its higher working temperature.
