More Benefits of Solar Thermal Systems

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 quality of water across the country, water heating systems need to be robust enough to survive atleast 7-10 years. Traditionally, solar water heating systems were made of Mild Steel with no coating. This led to these systems corroding within 3-4 years of use.

 

With advances in technology, solar water heating systems, these days, are largely made of Galvanised Iron (GI) or Stainless Steel (SS). The steel is covered with a corrosion protection coating such as enamel, epoxy, powder coating, etc to prevent salts, chlorides,  etc from corroding the metal.

 

Some companies also offer systems which are baked in an oven to ensure the coating adheres better to the tank, ensuring a long life. It is common to see these  heaters come with 5, 7 or 10 Year Warranties.

 

4. Solar Water Heating systems come in Multiple capacities

 

A family of four may need a much larger solar water heating system than a family of two. Similarly, if you have guests coming over often you may need to build some emergency capacity. If you are used to bathing twice in a day, this needs to be budgeted. Likewise, if your solar hot water system is to supply three bathrooms instead of one, the plumbing heat losses may be higher and must be compensated for.

 

Considering these needs, solar water heaters come in variable sizes – 100,125,150,200,250,300,400 and 500LPD are the common ones. If you are not sure what size of solar water heater you would need for your house, you can use this handy calculator which we have built for you.

 

5. Ideal for pressurized Applications such as Rainfall shower heads

 

If your home has a rainfall showerhead chances are you relish the idea of a hot water shower early in the morning or late in the evening after work.

 

Sometimes though, the absence of instantaneous hot water can be a real mood killer. Even worse is if your architect designed rainfall shower heads for your bathroom,but forgot to put a pressure boosting pump. Your water still trickles out from the shower, killing the experience of the bath.

 

Solar water heaters combine the world of high pressure with instantaneous hot water to give the ideal bathing experience for home owners. Some solar water heating systems are designed to operate at even upto 10 bar pressures and are often sold with booster pumps.

 

The company from whom you purchased the water heater can install the system on your terrace. Your plumber can then complete the installation of the system by integrating it with your home’s plumbing lines and you will have seamless delivery of hot water through your shower heads.
