Detailed information

Product detailed description

Gas condensing boiler Vaillant ecoTEC pro VU INT 256/3-3 - 27kW, wall-hung, for heating with the option to connect any external hot water storage tank via a high-flow three-way valve.

 

The boiler has continuously variable heating output control, which helps save both electricity and, above all, gas. It increases and decreases output smoothly. A weekly programmable thermostat with continuous modulation, or a weekly weather-compensated thermostat that also supports continuous modulation, can be connected to the boiler. Communication is carried out via three wires, which should not be run alongside electrical cables. A classic two-point thermostat can also be used, but the boiler will not then operate in modulating mode. For this reason, such a solution is not recommended.

 
 
The boiler also includes self-diagnostics for any faults, a backlit display showing heating status, a heating vent valve, a heating fill valve, and a safety valve.
 
Output setting (modulation) in the range of 37 to 100%.
 
Flue design: TURBO with continuous fan speed control.

 

Use:

  • designed for underfloor and radiator heating
  • compact boiler dimensions - low space requirements
  • also suitable for attic spaces
  • operation dependent/independent of combustion air supply

 

 

Advantages:

  • NOx value in flue gases below 60 mg/m3
  • standard utilization rate of 108%
  • continuous output modulation
  • simple display
  • Thermo-Compact module equipped with a stainless steel burner and fan
  • automatic diagnostic system 
  • option to prepare the heating system before installing the boiler itself
  • reduced electricity consumption 

 

ecoTEC pro VU INT 256/3-3

Nominal heat output range P at 40 / 30 °C 9.7 - 27.0 kW
 
Nominal heat output range P at 80 / 60 °C 9.0 - 25.0 kW

dobry den, uvazujem nad vymenou stareho kotla za tento model, mam podlahove kurenie cca 2x60m2 stare cca 14 rokov, zaujima ma ci je tato rada kotlov vhodna, alebo radsej niektory zo stacionarnych, podmienky jeho bezporuchoveho fungovania - udrzba pred vykurovaciou sezonou, co to obsahuje , priemerna cena takejto udrzby/revizie a priblizna zivotnost kotla ďakujem
A Avatar of author 06/12/2021 10:20
Dobry den, kupovat novy kotol a stacionarny by som neodporucoval. Jedina vyhoda spociva v tom, ze nemusia prerabat stare potrubie napojenia, ked povodny bol tiez stacionarny. Su to kotle, ktore sa postupne prestavaju vyrabat a nemaju tak prepracovane regulaciu a konstrukciu, ako zavesne kotle, ktore su najpredavanejsie u kazdeho vyrobcu a najziadanejsie, typ padom vyvoj ide o mnoho rychlejsie ako u stacionarnych. Vas vybraty kotol je pre tento typ vhodny, i ked su kotle s nižšim vykonom, a vsak na tento je znizena cena a vykonovo dokaze kurit na 9 kW, co pri vasom kureni, ak je to 120 m2, bude v prevadzke pri najnizsom vykone. Pozor, vybrali ste ti kotol s moznostou pripojenia zasobnika, NIE S PRIETOKOVYM OHREVOM VODY, to znamena, ze musite mat niaky zasobnik, ktory bude uhrievat. Udrzba by mala byt kazdy rok, to znamena len precistenie kotla, ako je horak, cena sa pohybuje okolo 40 €. Pokial kotol nebude v prasnom prostredi a voda nebude zanechavat vodny kamen, cistenie mozete robit mozno kazde tri-styri roky. No a priblizna zivotnost sa neudava, funguju aj 20 - 30 rocne kotle.

Dobry den,Uvazujem o kupe tohto kotla,bol by vhodny v systeme mam 8 clankovych radiatorov,Je potrebne aby bol zasobnik pripojeni ku kotlu ihned alebo sa moze pripojit neskor po odstavku el. boilera,Aky by bol k tomuto kotlu vhodny termostat s ekvitermickov regulaciou?Mate v ponuke aj kominove potrubie na prechod priamo cez stenu?dakujem
A Avatar of author 06/12/2021 10:19
Dobry den, kotol si mozete kupit a zasobnik pripojite az neskor. Kurit bude. Neviem ale s ucritestou napisat, ze ci bude stacit, alebo nie, skor by pomohla obytna plocha domu. Ale ked mate do niakych 200 metrov, je to v poriadku. Kominove prislusenstvo mame tiez, pri objednavke napisete vlastymi slovami o co ide a pri potvrdzovani objednavky vam oznamime cenu za kominy. Ekvitermicky termostat moze byt calormatic 470, https://www.atria.sk/vaillant-calormatic-470/ ten je aj najpredavanejsi

A Avatar of author 06/12/2021 10:17
Dobrý deň, obehové čerpadlo nieje z plastu ale z klasickej zliatiny. Rozdiel medzi Junkersom veľký nieje, sú to proste odlišný výrobcovia, ale na oba kotle na vysokej úrovni. Avšak musím Vám napísať, že z dôvodu vašej neistoty pri výbere kotla musím Vašu objednávku pozastaviť až kým nepotvrdíte správnosť výberu. Ďakujem za pochopenie a ospravedlňujeme sa za zdržanie. Pekný deň.

A Avatar of author 06/12/2021 10:16
Dobrý deň, pokiaľ mi píšete presný typ, tak v tom prípade by tam mal isť termostat ktorý podporuje moduláciu výkonu a to je len https://www.atria.sk/vaillant-calormatic-470/. Pokiaľ chcete lasnejší, doporučujem sa poradiť so servisným technikom, či tam môžete použiť dvojbodový termostat, tie sa hýbu okolo 40 euro. Pekný deň.

Dobry den, doporucujete mi kupit u Vas kotol kondenzacny alebo nekondenzacny s prietokovym ohrevom do komina ked mame byt 56 m2 so 4 radiatormi a sme tam 2 osoby. Cena pri nakupe spolu s montazou cini rozdiel cca 600eur. Je to len o uspore alebo o celkovom konforte ci zivotnosti kotla? Dakujem za odpoved.
A Avatar of author 06/12/2021 10:16
Dobrý deň, klasické NEkondenzačné kotle sa v podstate už nepredávajú, kondenzačný je vždy len o úspore plynu, ale o nejakej životnosti neviem či sa dá hovoriť, že by bola vyslovené dlhšia. Každopádne ak je rozdiel 600 euro, je otázny, kedy tie peniaze ten kondenzačný kotol zaplatí na úspore. To Vám už nikto presne nepovie. Pekný deň.

History of the company Vaillant

The history of the company Vaillant goes back to the year 1874, when it was founded by Johann Vaillant in Remscheid, Germany. Since then, the company Vaillant has been a leader in the field of heating and ventilation technologies.

History of the company Vaillant 

1874 Plumber Johann Vaillant founded the company.

1894 Patented for the invention of a gas water heater with a "closed system" design.

1899 Registered company logo, the Easter Bunny.

1905 Development of a wall-mounted water heater, patented under the designation "Geyser".

1924 Development of a wall-mounted boiler for heating.

1955 Production of the millionth appliance after the end of the Second World War.

1960 Production of electrical appliances begins.

1967 Development of a combined wall-mounted boiler.

1974 11 million appliances sold since 1974.

1992 Establishment of subsidiary companies – in the Czechoslovak Republic, Hungary, Poland and Turkey.

1993 Separation of Czechoslovakia leads to the creation of a separate sales representation in Slovakia.

1999 Anniversary, 125th anniversary of the founding of the company, 40 million appliances sold in the entire history of the company.

2001 The Vaillant Group is formed, covering eight significant manufacturers of heating equipment in Europe, including the boiler manufacturer Protherm in Slovakia.

Easter Bunny in the logo - intended for the success of the company

Pink dwarfs and cute animals stand around and admire the miracle of the egg. Johann Vaillant is fascinated by the scene and decides to buy both the picture and the copyright. For Vaillant, this means the establishment of its brand and an extremely successful story.

Very distinctive brand profile

Since 1899, the motif has adorned all products, catalogs and brochures. In a few short years, Vaillant built an excellent reputation that spread throughout Germany and even beyond its borders. Vaillant gave its logo clear lines and outlines. "The Bunny in the Egg" remains the central theme, but the word "Vaillant" is added.

Many Germans know that the Vaillant Bunny belongs to a company based in North Rhine-Westphalia. Moreover: more than 70% of all Germans have heard of the company Vaillant. In Austria and the Netherlands, the company achieves similar results for its image.
