Residential Space Heating & Cooling

Hot water is essential for residential houses, ensuring comfort and convenience for homeowners and their families. To meet this need reliably, we have installed a robust hot water system designed specifically for residential use.

Our setup includes a 300-liter tank to store ample hot water for daily household needs. This will ensure consistent hot water availability throughout the day. This configuration guarantees that residents can enjoy hot water whenever they desire, maintaining a steady temperature for their comfort.

This upgrade prioritizes the comfort and satisfaction of residents, enhancing their overall living experience. It’s our commitment to ensuring that homes are equipped with top-notch amenities that stand out for all the right reasons.

Energy Efficiency:

Our hot water system operates with exceptional energy efficiency, boasting a coefficient of performance (COP) of 4.4 when heating water from 15°C to 55°C. With an electricity consumption rate of 10.6 kWh per ton of hot water produced, our system significantly reduces energy usage compared to traditional setups. By employing innovative technology, we can potentially slash annual operating costs by up to 40%.

Low Energy Consumption:

The pressurized hot water module maintains water outlet pressure equivalent to municipal water supply pressure, eliminating the need for additional boosting pumps. This reduces system energy consumption, ensures a balance between hot and cold water pressures at the end, and facilitates easier temperature adjustments.

Stable Water Temperature:

Whether in the process of using hot water or heating cold water, the system handles cold and hot water separately, maintaining a constant supply water temperature at the set value.

Easy Installation and Flexible Site Selection:

The system allows for flexible site selection, with water tanks capable of being connected in series without being limited by the site. This enhances the ease of installation and the effectiveness of usage.

Modular Combination:

The system supports modular combinations, where a subsystem failure does not impact subsequent water tank hot water storage. It operates efficiently in winter with slow frost accumulation, and main unit defrosting does not affect the supply water outlet temperature, ensuring constant water temperature.
