Selection of the right water heater is important so that you get reliable and safe performance for years. Compromising on certain aspects can prevent you from enjoying hot water when needed. Following aspects are important at the time of choosing a water heater:
Both have their plus points. Storage water heater will give hot water at the set temperature upto 750°C and store it for later use too. Instant water heater will give hot water in minutes with no waiting time. However, Instant water heater will not give piping hot water in cold climate areas. It is more suited for moderate climate areas.
Choose the water heater according to your application and the number of persons using the same. The climatic condition of your city will also influence the capacity of the water heater
Hard water will cause scale deposits on the tank and heating element corroding them and result in premature failure. Increased energy consumption will also be there.
Glass lined tanks and copper tanks can withstand hard water without failure for years. Water heater with glass lined or copper tanks will last longer in hard water. Incoloy elements will last longer than ordinary element in hard water. Glass lining on tank and heating element will reduce scale deposits and avoid premature failure.
There are a number of safety features to prevent excessive temperature or pressure inside the water heater Thermostat, Thermal cutout and Multi Function Valve. These are as per IS standard.
Energy consumption in water heaters is surprisingly much lower than other household appliances mainly because water heater work for a very short time as compared to other appliances (Air conditioner, Refrigerator, TV etc.) Our models have star rating by Bureau of Energy Efficiency. Most of the models are either 4 or 5 star rated the highest energy efficiency rating.
MFV refers to Multi Function Valve.During heating the water inside the water heater will expand due to thermal expansion. The expansion of the water is allowed by the return of water back through the inlet line to the overhead tank. The Multifunction valve provided with the water heater has an inbuilt mechanism to allow thermal expansion of the water inside the tank during heating. In this manner the pressure inside the tank remains constant without increasing during each heating cycle.Note: For thermal expansion to take place it is important that there be no prevention of back flow of waterthrough the inlet line.Important: The MFV is a safety device provided with every water heater. It should not be disconnected from the inlet line or tampered in any manner to prevent its original functioning. This will not be safe and the warranty on the unit will be void.
When the water heater is connected to a pressure pump there are some important things to be noted. If the pressure from the pressure pump is beyond the rated pressure of the water heater (8 bars/kg/cm2), then the MFV water will be released continuously from the MFV even in cold condition. In this case, reduce the pressure setting of the pressure pump to a lower level. Further, during the heating phase, the water inside the storage tank will expand and try to go back through the Inlet line due to thermal expansion. But the Pressure pump on the inlet line will not allow the water to expand. So the water pressure inside the tank will increase and in such condition the MFV will start dripping to release the pressure and protect the tank from damage. This dripping is slow and intermittent and will stop as soon as the heating stops (when the heater switches off). The dripping will restart once the heating starts again. This is quite normal as the MFV is working properly to release the excess pressure insider the tank. In this case, please provide a PVC tube from the MFV to the nearest drain point. This will allow the expanded water to drain without affecting any internal fittings.Important: The MFV is a safety device provided with every water heater. It should not be disconnected from the inlet line or tampered in any manner to prevent its original functioning. This will not be safe and the warranty on the unit will be void.
In high rise buildings (20 floors or more) supplied from an overhead tank on the rooftop, there can be incidence of very high water pressure at the lower level floors. To protect the taps and fittings from damage due to high pressure, there may be a Pressure Reducing Valve fitted on the cold water line to the water heater. When the water heater is connected to a pressure reducing valve on the inlet line, there are some important things to be noted.During the heating phase, the water inside the storage tank will expand and try to go back through the Inlet line due to thermal expansion. But the Pressure reducing valve on the inlet line will not allow the water to expand. The water pressure inside the tank will increase and in such condition the MFV will start dripping to release the pressure and protect the tank from damage. This dripping is slow and intermittent and will stop as soon as the heating stops (when the heater switches off). The dripping will restart once the heating starts again. This is quite normal as the MFV is working properly to release the excess pressure inside the tank.In this case, first check whether the pressure reducing valve can be removed; if the line pressure does not exceed 6-7 bars/kg/cm2 it may be removed without affecting the water heater. If it is not possible to remove the pressure reducing valve due to technical reasons, then provide a PVC tube from the MFV to the nearest drain point. This will allow the expanded water to drain without affecting any internal fittings. Important: The MFV is a safety device provided with every water heater. It should not be disconnected from the inlet line or tampered in any manner to prevent its original functioning. This will not be safe and the warranty on the unit will be void.

When compared to an electric heater the Venus solar heater may sound slightly expensive. But a solar heater will pay back its investment in 2-3 years, through recurring energy savings.You may also be eligible for rebates on your electricity bills in some States.
Incase cold water supply is interrupted during the day , the heating of water by the solar system may not be affected significantly, although hot water cannot be drawn for use till the water supply is restored.
No, Solar hot water panels only heat water. They do not generate electricity from sunlight. As the sun hits the glass tubes in the panel, water gets heated and flows back into the tank. Solar electric panels are made of silicon and convert sunlight directly into electricity. They are different from solar hot water panels.
The VTC model solar water heater will continue to function even on cloudy days due to heat absorption from the infrared rays of sunlight. Efficiency would be affected, however, on rainy days.
Hot water produced by the solar system during the day is stored in an insulated storage tank. The insulation of the tank is such that the water remains hot without significant drop in temperature for around 24 hrs. Thus water heated during the previous day is available for use the next morning.
Venus VTC solar water heating systems do not need significance maintenance. The collector tubes may need annual cleaning to remove accumulated scale and sediment deposits at the bottom. The system is resistant to adverse effects of weather as it is made of stainless steel.
Using the Hot water in the evening or night will result in hot water being unavailable the next morning as the system will not heat water overnight. If you wish to use hot water in the evening too, then choose a larger capacity of solar water heater that meets your needs.
Venus VTC solar water heaters can last for 15-20 years depending upon the general upkeep.

Heat pump water heaters are engineered to use renewable energy heat sources from the ambient air to heat water. They work like a refrigerator but in reverse. They are highly energy efficient as most of the energy for heating comes from the external environment and only a fraction comes from electricity. Thus for 1KW electricity consumed the heat transferred will be 3KW. The amount of electrical energy needed to heat water is greatly reduced thus saving energy.
A heat pump water heater can operate between -7°c to 43°c with highest efficiency.
The maximum temperature it can provide is 60°c.
It can be conveniently installed in a clean, dry room including basements, attics and utility rooms. It should be placed at a practical location to prevent long un-insulated hot water lines to be installed that waste energy and water. The room should be at least 700 cubic feet and be well ventilated. Commercial heat pump models can be installed on rooftops open to atmosphere.
First, the amount of water required has to be calculated and accordingly a suitable size has to be selected. For further professional assistance please contact our sales consultant.
No, most modern heat pumps are very quiet. The source of noise in a typical heat pump is the air passing over the grill, as it is blown through the unit. This sound is usually only marginally higher than ambient room noise.
While solar water heating systems do produce free hot water, they can only operate when there is sufficient sunshine. Therefore they have to rely on an electrical backup on cloudy/rainy days & in winter which adds to the electricity cost. The heat pump water heaters on the other hand can work in any weather, day or night without the use of a backup system right down to -7°c. The volume & temperature of hot water from a solar system will vary with weather; in a heat pump water heater this is constant & irrespective of weather conditions.
Major energy savings upto 75% compared to electric water heaters. Households or commercial enterprises with large hot water usage can get huge savings from a heat pump water heater. Convenience of always available hot water. Environment friendly, green technology. No electric heating elements; safer & more reliable system.
The salient features of the VENUS heat pump water heaters are: Wide range of working temperature from -7°c to 43°C. Heavy duty compressor which is durable and energy efficient. Microprocessor based control system for precise & convenient operation. Multiple safety features for protection against overheating, high current, etc that ensures stable operation. Compact size and ease of installation. Can be installed in any convenient location. Can be scaled to meet requirements from individual villas to large commercial installations. High energy efficiency- Coefficient of performance (ratio of output power to input power) can be as high as 4.
There are no subsidies, however, any commercial or industrial enterprise can avail of accelerated 80% Depreciation on their investment in Heat Pump Water heaters which are classified as œEnergy saving Devices under Income Tax Act. Additional depreciation benefits will reduce the payback time for these enterprises.
