In heating systems, energy efficiency, domestic hot water comfort, and low operating costs are of great importance today for both residential and commercial users. Developed to meet these needs, the WT-S DHW Series Condensing Boiler with Internal Hot Water Storage Tank stands out among modern condensing boiler solutions that combine high thermal efficiency, rapid hot water production, and advanced safety systems.
Available in 45 kW, 55 kW, and 65 kW capacity options, the WT-S DHW Series provides high domestic hot water comfort thanks to its internal hot water storage tank, while contributing to energy savings with its stainless steel heat exchanger structure and 5:1 modulation technology. In addition, it stands out as an environmentally friendly heating system thanks to its low NOx and CO emission values. In the rest of this article, we explained all the features of the boiler in detail.
The WT-S DHW Series condensing boiler models attract attention with their high-efficiency heating performance, domestic hot water comfort, and safe operating principle. The series includes models with heating capacities of 45, 55, and 65 kW. Depending on usage requirements, internal hot water storage tank options of 60 liters, 90 liters, and 120 liters are available.
The large-diameter stainless steel heat exchanger used in the units ensures long service life and high thermal efficiency. In addition, the high-efficiency circulation pump with PWM drive, illuminated LCD control panel, and highly insulated body design are among the other prominent technical advantages of the product.
Condensing boiler systems with internal hot water storage tanks ensure fast and stable domestic hot water supply. Thanks to the internal hot water storage tank in the WT-S DHW Series, user comfort is significantly improved, especially in buildings with high domestic hot water demand.
Thanks to the 60 L, 90 L, and 120 L tank options, solutions suitable for different usage intensities can be provided. The system delivers high-flow domestic hot water continuously, creating a comfortable hot water experience at multiple usage points simultaneously.
The heat exchanger structure used in condensing boilers is one of the most important components directly affecting the efficiency and service life of the unit. The stainless steel heat exchanger with enlarged pipe diameters used in the WT-S DHW Series increases system efficiency by providing high heat transfer performance.
The stainless steel structure also offers long-term and safe operation thanks to its resistance to corrosion. With this structure, the high efficiency provided by condensing technology can be maintained more consistently.
The 5:1 modulation technology used in the WT-S DHW Series allows the unit to automatically adjust its operating power according to the required capacity. Thus, instead of continuously operating at full capacity, the system consumes only the amount of energy needed.
Thanks to this technology, unnecessary fuel consumption is reduced while energy savings are achieved. At the same time, frequent start-stop cycles are prevented, resulting in quieter operation and extended equipment life.
The WT-S DHW Series offers three different capacity options: 45 kW, 55 kW, and 65 kW. Each capacity group includes different tank volume options referred to as L, H, and XH.
The internal hot water storage tank options in the series are available in 60 liters, 90 liters, and 120 liters. This allows solutions suitable for a wide range of applications, from small-scale buildings to commercial projects with high domestic hot water demand.
The WT-S DHW Series condensing boiler models operate at low noise levels thanks to their body design with high thermal and acoustic insulation. The quiet operation feature provides a significant advantage, especially in projects where installation is close to living spaces.
The high-efficiency fan and circulation pump used inside the unit also contribute to reducing vibration and noise levels. As a result, users can experience a more comfortable heating environment.
The WT-S DHW Series is equipped with many advanced safety systems for safe operation. The units include an ionization-controlled flame safety system. Thanks to this system, flame control is continuously monitored.
In addition, safety measures such as flue gas temperature control, overheat protection, frost protection system, and low water pressure safety contribute to the safe operation of the unit. These systems support both user safety and equipment protection.
The WT-S DHW Series is designed to operate with both natural gas and LPG. This provides flexibility of use in projects with different infrastructure conditions.
In regions where natural gas is unavailable, the system can also operate efficiently with LPG as an alternative energy source. Thus, a wider range of applications can be achieved for different building types.
WT-S DHW Series condensing boilers feature low NOx and CO emission values. Thanks to their low-emission operating principle, the amount of harmful gases released into the environment is reduced.
Especially today, when energy efficiency and environmental sustainability are becoming increasingly important, low-emission systems provide an environmentally friendly approach while also complying with modern building standards.
Regular maintenance is of great importance for long-lasting and highly efficient operation in condensing boiler systems. Elements such as sludge, metal particles, and limescale that may form inside the installation can negatively affect system performance.
For this reason, periodic maintenance is recommended every 6 months to 1 year in the heating installation circuit. Especially in old systems, installation cleaning should be carried out with a flushing application before commissioning the condensing boiler. In addition, the application of organic protective solutions helps prevent corrosion on metal surfaces.
The WT-S DHW Series is preferred in many different application areas such as villas, apartment buildings, commercial buildings, hotels, restaurants, and social facilities where high domestic hot water demand exists.
Thanks to its high domestic hot water capacity and strong heating performance, it also offers effective solutions for central heating system applications. Different capacity options allow product selection according to project requirements.
For condensing boiler systems to operate safely, the unit must be installed in compliance with regulations. It is important that the boiler room has adequate ventilation and that combustion air inlets are not blocked.
In addition, flammable and explosive materials should not be kept near the unit. If a gas smell is detected, electrical devices should not be used, gas valves should be closed, and the relevant gas supplier should be informed. Preventing unauthorized intervention outside authorized service providers is also important for safe operation.
WT-S DHW Series condensing boiler models are covered by a 2-year warranty, provided that commissioning is carried out by an authorized service provider. Within the warranty scope, maintenance and service operations must also be performed by authorized services.
Improper use contrary to installation instructions, incorrect electrical connections, use of unsuitable fuel, or unauthorized interventions are considered outside the warranty scope. Regular maintenance applications contribute to longer service life and higher performance of the unit.
