A distinctive feature of these boilers – a new design of stainless steel heat exchanger with reduced hydraulic resistance, and thus lower operating costs. Boiler efficiency can reach 109%, taking into account the use of higher calorific value. New models offer improved operational characteristics and thermal insulation according to the highest standards. Automatic adjustment of partial load for long periods of continuous operation. As a result, the service life of the system increases it depends on the number of starts and much less on the operating time , gas losses and heat losses are reduced the boiler is cooled during downtime, and the less downtime, the less energy is needed for heating it .
Wall condensing gas boilers Vaillant ecoTEC plus high power
Most of the wall hung boilers on the market, regardless of their type, have a capacity not exceeding 35 kW. If you need more, you either need floor standing boilers, or wall mounted boilers in cascade, or choose from a relatively small number of models. It is also worth remembering that condensing boilers are becoming increasingly popular. And if they are not widespread among our private users, it is only because installation in new buildings or complete rework of all heating systems is desirable to use their capabilities to the maximum. However, the larger the heated area, the higher are the heating costs, and even 10-15% of the difference costs a considerable sum.
Wall hung condensing boilers from Vaillant are represented by EcoTEC plus series, which until recently consisted of two lines: models with maximum output of 24, 30 and 37 kW, including versions with built-in boiler and two boilers of 46 and 65 kW.
As we are talking about condensing boilers, it is worth noting that such results are obtained only when they are used with low-temperature heating systems water temperature in the circuits is around 40-50 °C in the flow and 30-40 °C in the return , in high-temperature systems, the apparent heat output will be somewhat lower. The new models in this series are three boilers with outputs of 80, 100 and 120 kW.
Burner modulation range – from 20 to 100. The models can be retrofitted with indirect water boilers for hot water preparation. These boilers feature new construction of stainless steel heat exchanger with low hydraulic resistance, and thus low operating costs.
Boiler efficiency can be as high as 109%, taking the calorific value into account. The new models offer improved operating characteristics and thermal insulation that meets the highest standards. The automatic adjustment of the charging rate secures a long period of continuous operation.
As a result, the system life increases it strongly depends on the number of starts and much less on the operating time , the unavoidable gas losses at every start-up are reduced the boiler is cooled during downtime and the less downtime it has, the less energy is needed for heating . Standard type control panel, located under the hinged front flap, with the possibility of installing additional electronic controllers directly in it.
Boilers can be used in complex heating circuits. The boilers can also be realistically used in cascade systems: up to six boilers can be combined in a cascade, i.e. tuned to the space available. e. full output of the system can reach 720 kW.
