Hot Water Generator

Now Experience The Luxury Of 75% Power Savings.

EcoHot - The Hot Water Generator

How water is an essential requirement in hotels, hospitals and spas. However, most of them use either electric water heaters or boilers to heat water, both of which consume a lot of energy, resulting in very high running costs.

A new product from the leaders in airconditioning

Blue star has been a leader in the Indian commercial airconditioning business for 70 years now. Its newest innovation, EcoHot - the Hot Water Generator, is an air source heat pump which functions on a basic refrigeration cycle, common to all refrigeration and airconditioning systems. The unique advantage of this system is that it also utilises ambient heat energy to generate hot water, thereby, substantially saving on running costs. In conventional heaters, 1 KW of electrical energy provides 1 KW of heat output. These systems are not energy efficient as their COP is 1. In Blue Star's EcoHot, when 1 KW of electrical energy is given to the compressor, the system delivers 4 KW of heat output. In otherwords, EcoHot consumes only 25% of electrical energy as compared to conventional heaters. And the same principle applies for boilers, only in this case the savings can be as high as 66%.

Comparison With Other Systems

Operation cost is only

One-fourth of that of electric water heaters
One-third of that of boiler systems.


Blue Star's EcoHot consists of an air-side heat exchanger, water -side heat exchanger, compressor and an electronic valve. The high pressure and high temperature discharge gas goes to the water-side heat exchanger through a tube. This heats the circulating water. The liquid refrigerant then passes through the electronic expansion valve. The opening and closing of the valve depends on the set water temperature. The low temperature refrigerant then passes throug the air-side heat exchanger, becomes super-heated vapour, which is used for hot water generation.

Advantages of Blue Star EcoHot

• High COP hence low running cost.
• Low space requirement.
• Maintenance friendly
• Wide operating conditions.
• Highly reliable
• Easy and quick installation
• Accurate temperature control
• No pollution
• Simple to operate

Key Features

Scroll Compressor

Blue Star's EcoHot comes with a special series of scroll compressors meant for hot water applications. These scroll compressors have very few moving parts and are high in volumetric efficiency. They also have a better liquid handling capacity and hence are ideal for varying load conditions. What's more, they don't wear out, making the efficiency of the system consistent throughout its life.

Accurate Water Temperature

Blue Star's EcoHot is fitted with an electronic expansion valve which can operate from 0 to 480 steps. The opening and closing depends on the inlet and the outlet temperatures of the water. This enables the system to eliver water at the required temperature, to accuracy levels of +/- 1°C.

System for all Seasons

The system is designed to work in extreme conditions, which means that it can work at temperatures as low as -7°C and as high as 43°C
Advanced Controllers
Blue Star's EcoHot comes with the latest advanced controllers. This allows connectivity with 16 units as well as the setting of individual parameters separately.
The following are the key features:
• Temperature settings
• Error code display
• Lock options
• Daily programming
• Parameter settings

Scalable Option

The system comes with an advanced controller that can connect up to 16 units. The parameters of each unit can be set individually, making it convenient for the end user. This feature also helps install the system in a phased manner when additional rooms/areas are planned for future expansion. The controller will automatically control the number of units needed to run, based on the hot water demand.

User Convenience

Blue Star's EcoHot unit can be programmed to automatically switch on, based on the need and usage pattern. This avoids the hassle of the user turning the system on/off every time. There is no need of manual intervention like other systems.

Service Friendly

The system is very simple in principle.Moreover, the controllers are armed with some advanced features like error codes, enabling the technician to identify the problem and resolve it immediately. This reduces turnaround time and increases uptime of the system.

Safe and Reliable

Unlike electric water heaters, Blue Star's EcoHot completely isolates water from electricity. This totally eliminates the chance of an explosion caused by dry combustion and the risk inherent to a fuel storage tank, as in gas or diesel fired boilers. Making it the safest and the most reliable system compared to conventional hot water heaters.

Easy Installation

EcoHot is very easy and quick to install, unlike other systems. It is also very easy to operate. So you don't need a qualified technician to operate the system.

Space Saving

EcoHot is very compact and the space saved can be utilised for other purposes that can benefit the customer.


Blue Star's EcoHot models of 36KW and 65 KW capacities come with multiple compressors. The advantage of this is that in case of part load conditions one compressor remains off, saving substantial power. Even in the event of a compressor failure, the other compressor continues to function. Ensuring at least 50% of the output. The system can also be made modular by connecting multiple units, thereby avoiding the need of a standby system.


EcoHot is extremely hassle-free since it needs only a tank to be connected. It is very easy to use and operate. What's more, with this system there's no need for fuel storage tanks, big chimneys, standby and pollution control board clearance.

Retrofit Friendly

EcoHot is a simple system which can be installed easily and quickly. In existing establishments, it can replace old, conventional, power-gulping systems without much alteration work. Even hot water pipes can be retained as it is without any major modifications.

Advantage Blue Star

Blue Star's EcoHot is similar to most basic refrigeration and airconditioning systems. Blue Star is a pioneer in the airconditioning industry, with over seven decades of expertise. With a superior range of products, widely trained dealer network across the country and over a million TR in annual maintenance contracts, you can be assured of high service standards that result in high uptime and peak efficiencies.

Pollution Free

Boiler systems generally emit gas which pollutes the atmosphere. They also need chimneys which can disperse the gas at a stipulated height, as per the statutory norms. But in the case of EcoHot there is no emission of pollution causing gas. On the contrary, it releases cold air which helps in cooling the surrounding ambient.
