SOLAR WATER HEATERS IN PAKISTAN
Enerquip is Pakistan’s largest solar water heater importer, stockiest and service provider with thousands of installations throughout Pakistan.
WHAT IS A SOLAR WATER HEATER?
Solar water heater (SWH) is the conversion of sunlight into heat for water heating using a solar thermal collector. A variety of configurations is available at varying costs to provide solutions in different climates and latitudes. SWHs are widely used for residential and industrial applications. A sun-facing collector heats a working fluid that passes into a storage system for later use. The warming impact of radiation is clear and it’s standard that a container of cold water, left exposed to the sun are raised in temperature, Enerquip’s solar water heater uses the latest technologies to efficiently absorb the heat of the sun and transfer it to heat water. The Insulated Solar water heater tank will store hot water over night. Solar water heater are popular worldwide and are being used on mass scale in countries such as China and Turkey best alternative energy solution at Enerquip.

HOW DO SOLAR WATER HEATING SYSTEMS WORK?
Solar Water heater includes two main components;
First: Evacuated Tube: Absorbs solar energy and converts it to usable heat. A vacuum between the two glass layers insulates against heat loss. Within each solar evacuated tube, 3 systems are used to ensure the most effective heat absorption. This included a AL-N/AI (aluminum nitrate) layer but also a second aluminum layer as well as a third copper layer. The added layers conduct heat better and also stabilize the coating allowing for a much longer lifespan of 20 year or greater.
Second: Water Tank: Consists of 3 layers; 1. Inner Tank: made up of stainless steel 2. A 60 mm Poly Urethane gun filled insulation. 3. Outer Tank: made up of painted steel. Water tank stores & retains water temperature overnight A home solar water heater is a very simple and maintenance free way to immediately reduce your monthly energy transformation cost. In a solar water heater, cold water flows into the bottom of the solar vacuum tubes & convection drives the movement of the water around the system. When the water gets heated through vacuum tubes, it rises to the top of the tank. The colder water falls back down the evacuated tube where the process can start again. The evacuated tubes are very efficient at trapping heat from the sun and transferring it to the water.
A Digital Controller electronically controls electric element & Water pump by intelligently monitoring water level and water temperature. It has three working modes i) Manual ii) Timing & iii) Intelligence Manual Mode: the device will neither automatically start water filling nor automatically start heating. On the basis of need, the user can press buttons to open or cancel water filling or heating. Timing Mode: Users can set three times for motor or valve controller water filling and three times for electric heating. Intelligent Mode: In this mode, controllers intelligently controls water inlet and electric heater.
EnerQuip’s Solar Electric Hybrid Water Heater
EnerQuip’s digitally controlled solar water heater is the most efficient water heater available in the market today. Utilizing solar (primary) and electric power (as back up) to heat your water. Water is heated throughout the year through the sun and the system automatically shifts to electric power in case of cloudy and/or low sun radiation days. EnerQuip’s solar water heater tank is insulated by a thick 60mm layer of polyurethane which helps it to hold temperature over night with minimum temperature loss. Our Smart Digital controller has two major functions that improve the system’s efficiency;
1) It governs the electric heating element and manages the temperature within the tank on its own.
2) It manages water inlet and fills cold water intelligently so that the overall temperature in the water tank does not drop.
EnerQuip’s Solar Electric Hybrid Water Heater vs Stand Alone Electric water Heaters
Stand alone electric heaters are readily available in the market today, however, as they rely 100% on electric power and with sky rocketing electricity prices, they are extremely expensive to operate. Another major drawback of conventional electric water heaters is that they loose heat rapidly as they tanks are mostly not efficiently insulated. Compare that to the features available with the EnerQuip’s water heater and you will not regret your decision of installing EnerQuip’s Solar Electric Hybrid Water Heater.
EnerQuip’s Solar Electric Hybrid Water Heater vs Natural Gas water Heaters or Geysers
Natural Gas Fired Water geysers or heaters have been the most widely used water geysers in the country since the past many decades. However natural gas is no longer a widely available resource and natural gas reservoirs of the country are fast depleting, which is why natural gas is seldom available in the winters and on top of that the government of Pakistan has banned new natural gas connections for domestic use. Apart from this, the gas geysers available in the market today are highly in-efficient as they run on the same 50-year-old technology with no provisions of tank insulation to retain water temperature and they heat water through a gas burner with burns gas on a non-stop basis which is not free.
