Product Description

Nowadays, due to the constant rise in oil prices, there is an increasing need for energy efficient products that provide greater savings to users. The hotel industry is among the most energy-intensive sectors of the economy, meaning soaring costs for operating the facilities. Most of the hotels use conventional and energy-inefficient systems such as conventional boilers in order to produce domestic hot water. The need to find more economical energy upgrading solutions for existing installations is imperative. The attention of interested parties is mostly directed towards the use of heat pumps or solar energy.
These and many advantages prove that the use of a heat pump is the best solution for the needs of a hotel.
Main advantages of using a heat pump compared to a boiler:
• Energy upgrading of buildings
• Energy efficiency and operating cost reductions up to 70%
• Return on investment approximately within 3 years
Main advantages of using a heat pump compared to a central solar field:
• Faster return of investment
• Less space required
• Less need for maintenance
• Smaller volume of hot water storage tanks and hence less space for boiler rooms

Powerful Heat Pumps for Commercial Hot Water
Energy consumption of hot water accounts for a considerable percentage in commercial buildings. According to some investigation, this percentage can even be as high as 40% in some hotels, nursing homes, hospitals etc. Heat pumps, however, generate hot water mostly with renewable energy are especially suitable for commercial hot water project. Using KOLANT heat pumps as the heating devices or replacing those existed boilers in commercial buildings makes great benefits in economic and environmental prospects. With large capacity range from 10kW to 250kW, KOLANT commercial heat pumps provides various choices for users to get the most cost-effective solution for hot water projects.
