How to save 30 to 40 % electrical energy

 

Solar Water heater

M/S PMM Smart Future solution – Ranipet – Supplying solar water heater Brand of Hi-Tech and Supreme make Quality product supplies our Aim

00) Why you need to install solar water heater?

In every home consumes ~ 30% electrical energy for heating purpose, this can be saved by using Solar water heater.

01) What is solar water heater?

A solar water heater is a device that captures sunlight to heat water. It can be an economical way to generate hot water for your family (for shower and bath). A solar heater not only enables substantial energy savings as solar power is free in non renewable energy of natural gas, wood, fuel oil etc.

02)   How it works?

The sun's thermal energy heats the fluid in the solar collectors. Then, this fluid passes through a heat exchanger in the storage tank, transferring the heat to the water. The non-freezing fluid then cycles back to the collectors. ... Direct systems circulate water through solar collectors where it is heated by the sun.

03)How many type of solar water heater available in Market?    

PMM Smart Future solution – Ranipet – Supplying 2 types of solar water heater

a)     Evacuated tube collector (ETC)

b)    Flat plate collector (FPC)

b) ETC Solar Water Heater

 

	b) PFC Solar Water  Heater

                                                

04) How to select the solar water Heater?

The thump rule is 25 Litre per person, If 4 people is available in home should select 100 LPD (Litre Per Day) and need to take consideration water loss will be 10 to 20% the hot water tank to tap based on the distance loss shall be calculated.

 05) PFC and ETC which one is more efficient?

S.No	Evacuated Tube Collector (ETC)	Flat Plate Collector (FPC)
1	Quickly heat water	Slowly heat water
2	The efficiency of the collector on higher temperature is high	The efficiency of the collector on higher temperature is low
3	Negligible heat loss in the tubes during the daytime (evacuated tube solar water heater)	Higher heat loss (due to convection) in the collector & tank during the day-time
4	Convection and Convecting losses are low	Convection and Convecting losses are high
5	Low emissivity	High emissivity
6	Satisfactory performance (-18 deg. C) even in extreme cold condition	Freezing of water will take place at high altitude can cause damage to the collector
7	Temperature range (heat water) from 60degrees to 120 degrees	Temperature range (heat water)from 60 degrees to 80 degrees
8	Easy to replace glass tube	Difficult as well as expensive to replace glass sheet
9	Negligible scaling of tubes which can be cleaned manually (inner tube dia. Is 37mm) hence, loss of efficiency consequently is minimal	Heavy scaling of the copper/aluminum tubes which cannot be cleaned manually as the bore dia. is 12.50 mm hence, giving rise to a substantial loss inefficiency of the system.
10	In locations with an average availability of solar energy over-sizing of the system glass tube collectors are not required	Higher system sizing is required to get the desired result and therefore added extra cost
11	Heat exchanger not required	Heat exchanger required
12	Advanced technology at competitive price	Old technology at higher prices
13	Provision of a hot water facility for 350 days a year	Provision of a hot water facility for 300 days in a year
14	System life above 5-15 years	System life over 25 years
15	Water quality does not affect the system	Water quality affects the heating system forming scale over a metal tube
16	Low maintenance	High maintenance
17	Grouting of Collectors not required	Grouting of collectors are required
18	The collector glass tube absorbers (being cylindrical the incident) absorbs the sun’s rays on the tubes is at 90 degrees throughout the day. Hence peak heat absorption as always	The collector fins & tubes (being flat the incident) absorbs sun’s rays is at 90 degrees at noon only for peak absorption
19	System hot water tank only is insulated using polyurethane insulation material, which does not absorb water or moisture	Collector & tank insulated with glass wool/ rock wool absorbs moisture & gets wet during monsoons reducing the efficiency of the system

 06) What are the Major parts of ETC solar water heater?

a)     Evacuated tube

b)    Water tank

c)     Stand

07) What is Evacuated tube?

Evacuated tube solar collectors convert energy from the sun. They have a vacuum between two glass layers and work similar to a thermos flask allowing it to retain up to 95% of the solar energy they capture!

08)   What is solar water tank?

The solar water tank contain two tank inside tank which is made Stainless steel or Mild steel tank and then heat exchanger which is work as insulator to avoid the heat loss and outer side tank which is made of Stainless steel or Mild steel , the Mild steel coated with power coating.

09) Solar water heater is ETC and PFC is coming in two type based on the application

a)     Solar water heater non pressure system , which is used for normal water where the water flows on gravity, the water flow less the 1.0 Kg/Cm² pressure maximum

b)    Another one is Solar water heater pressure system , which is used for pressurised  water where the water pressure pump installed or more pressure in the water flow, the water flow pressure found 2.0 Kg/CMm² to Maximum 7.0 Kg/Cm² pressure maximum.
