1. Quick and easy to install   One of our partners at Solar Hitech, timed the solar water heater assembly process over a four year period. Here are the statistics for a 100LPD system (suitable for a family of 2):   • 2016 – 30 minutes • 2017 – 20 minutes • 2018 – 18 minutes • 2019 – 16 minutes Even at 20-30 minutes, a solar water heating assembly is pretty,darn fast. Larger capacity systems do take slightly longer.   If the water heating system is to be integrated into an existing plumbing line, a 100LPD system can be completely commissioned within 1-1.5hours.   2. Have a long life   A lot of this depends on the water quality. In areas with moderate to good water quality, solar water heaters can last more than 15 years. Even in areas with bad water quality, these systems last atleast 7-10 years. This is still much cheaper than owning an electric water heater or gas geyser which have comparable life spans but with substantial operating costs during ...

1. SWHs offer a near instantaneous source of hot water   Of course, this, to an extent, also depends on how good your plumbing line is. With modern composite pipes, heat loss from plumbing lines is minimal. It is safe to say that solar water heater storage tanks can deliver 90% of the hot water output at their outlet, to the bathrooms.   2. They work during continuous periods of no sunshine   Solar water heaters have large, insulated storage tanks. There is a main tank which stores the water. This is followed by a layer of Insulation, usually PUF or Rockwool, and then a final layer of a PPGI/SS/Aluminium outer cladding to cover the insulation. These layers of insulation are often 50-75mm thick, thick enough to hold the heat within the water for 3-4 days. Overnight heat losses are minor, making them ideal for regions with continuous periods of heavy rainfall.   3. Highly suitable for varying water conditions   With the degrading and highly variable quali...

1. Solar Water Heating Systems are a better choice for your terrace space than Solar Power systems.   I am sure most of you reading this are surprised. But honestly, your terrace doesn’t care much for Solar Thermal or PV. All it cares about is how well the space is being utilized.   Solar Thermal technology, specifically solar water heating technology works at 80-90% efficiency whereas Solar PV technology (PV is Photovoltaic- a fancy word for Solar Power) works at 15-20% efficiency.   What this means is that a solar water heater system generates the same amount of energy in a 1m2 area which a solar power pack system takes 4-5m2 to generate.   Well you might be wondering if this is a fair comparison. Solar thermal systems are used to heat water whereas solar power systems are used to generate electricity. Fair point. But in terms of energy conversion all that matters is what goes in and how much comes out  – the overall usefulness of the system.   ...

All hot water storage tanks must be well insulated to keep the water hot during the night. Heat loss depends on many factors (ambient temperature, wind, season, etc.) and will be approximately 0.5 to 1 Centigrade per hour during the night. Experience shows that a minimum thickness of insulation of 100 mm should be maintained. There are several different sizes of tanks available. All tanks must have connections for cold water inlet and hot water outlet as well as two connections for circulation pipes. These hot water storage tanks can easily be fitted to a stand. An electric element can be inserted, even after the installation, as there is a flange for this purpose. The flange at the bottom serves also for cleaning and maintenance of the tank. These hot water storage tanks are made for low pressure use only. They can withstand a pressure of approx. 30 meters head. It is important to select correct connections to guarantee trouble-free functioning (as shown in the drawings). Shape -tw...

Basics -the plumbing for hot water is in principle the same as for cold, but there are certain additional factors that apply to hot water systems, and these must be taken in account (e.g. Iength and diameter of pipes, insulation, safety devices, etc.). Layout of pipelines -connection of hot water storage tank and collectors to be of shortest possible distance. -Pipes should not be exposed to the weather if possible. (keep pipes inside the house where possible). -All connections must be of good quality. -Adequate spacing must be left for insulation (insulation thickness: 30 to 50 mm). -Air valves and drainage valves must be in accessible places. -Layout must allow complete drainage of the entire system. Diameter-pipe diameter depends on different factors, such as: - Consumption/time unit - Total quantity/time - Length,  Materials, etc. To ensure trouble-free functioning there must be a safety device for the release of over-pressure due to the increase of volume by heati...

Welcome to another exciting edition of Inspector Pumphead’s Classroom! In this feature, we’ll be talking about various small, simple pump “How-To’s” that any homeowner or facilities manager can tackle. How to Replace the Cartridge on a  Taco 007 Circulator Pump. As the name suggests, circulator pumps are used to keep hot water circulating throughout your water system so that it is immediately available at point of use. For those of us who live in colder climates, the coming winter months are a particularly annoying time to have to wait for water at the sink or tub to heat up. The presence of a circulator pump ensures that hot water is always readily available. The Taco 007 is built for quiet operation in hydronic heating, radiant heating, hydro-air fan coils, indirect water heaters, chilled fresh water and domestic water circulating systems. The cartridge style design means the actual circulating mechanism is contained in an easily serviceable or replaceable single unit....

What are flanges? Flanges are used to connect pipes to pumps, valves, and other components. They come in a variety of shapes and sizes to specifically suit different applications. Flanges can be made of such materials as bronze, cast-iron, stainless steel, and brass. Below you will find a brief description of some of the more common types of flanges. Types of flanges Slip On Flange Slip on flanges are slipped over a pipe and fillet welded from both the inside and the outside to strengthen the connection. These flanges are suitable for low temperature and pressure applications. Slip on flanges come at a low cost and require less accuracy when cutting a pipe to length. Threaded Flanges Threaded flanges are fast and simple to attach. Threaded flanges are similar to slip on flanges however the bore is threaded which allows for assembly without welding. This type of flange is not suitable for high pressure and high temperature applications. Lap Joint Flange Lap joint flanges are ...

Selecting the right replacement pump can truly be a daunting task. Numerous classifications and scores of different models all built to different specifications and applications can leave some people overwhelmed. That’s why our experts are here to help. Below you will find five general things to know before you pick out a new pump including some questions our experts might even ask. What Are You Pumping? The first and perhaps most obvious thing to keep in mind when selecting a new pump is of course knowing what you need to pump. Having a pump that is not suited for a certain type of fluid can lead to corrosion or unnecessary wear and tear. There are pumps designed to pump all sorts of materials including oil and chemicals while others can only pump water. Some pumps can also handle solids such as slurry and waste while others are designed to only handle liquid. Knowing if you require a pump that is designed to handle certain fluids and solids is essential. Where Are You Pumping? T...

Believe it or not,  Jet Pumps  are not associated with the awful New York football team. They are referred to as such because they work similarly to a jet engine in the way they create large amounts of pressure. Jet Pumps  are mounted above ground and are non-submersible. They are typically used to draw water from a well through a suction pipe in order to provide potable water or domestic water pressure. Other common applications (though certainly not limited to) include light commercial or residential irrigation and supplying water for sprinkler systems.  Jet Pumps  are typically more popular in warmer climates or areas with high water tables. Jet pumps  come in two variations: deep well and shallow well. The type of  jet pump  most suitable for your application will be dependent on the depth of your well.  Shallow well jet pumps  are used to transport water from wells as deep as 25 feet.  Deep well jet pumps  are gene...

In domestic, industrial, commercial and agricultural sectors, pumps are used to extract water from the water table under the soil. While in some places getting portable water is simple, in other places, where the water table is at a lower level, powerful pumps are required to extract water. These pumps operate under pressure to extract water to your home. There are an array of water pumps that can be used to extract water, from mechanical to jet and solar to submersible water pumps. The right water pumps for your use are usually sized by experts. This basically depends on the gallons of water that will be required for use during the peak usage time. Based on this, the right pump that can ensure your water needs is selected. Water pumps selected rightly for the job are durable and last several years. For residential use, the two common types of water pumps used are submersible pumps and jet pumps. Submersible pumps Submersible pumps are long cylindrical pumps that are about 2-4 ...
