1 Introduction

• 1.1 What is a Solar Powered Hot Water ?

– Solar hot water systems consist of solar collector

panels on the roof of a building and a storage tank The sun's rays heat the water much the same as

water in a hose left on the lawn on a hot day

Because they only generate hot water when the sun

is shining, they are generally equipped with a gas or

electric or heat pump booster to ensure you don't

run out

– Some systems have the storage tank and the solar

collector panels on the roof However, if you don't like the look of the storage tank on the roof or if your roof can't support the weight - you can choose a

pumped system that has only the collector panels on the roof, while the tank is at ground level

• 1.1 What is a Solar Powered Hot Water ?

– A Solar Hot Water System requires only daylight to generate heat so can still generate hot water on a

cloudy day There are three main components in a

Solar Hot Water system for domestic applications:

• Solar Panels – that collect heat from ambient daylight

and transfer it to a solar fluid (a glycol/water solution).

• Plumbing System – which includes simple piping and a

pump, to pump the solar fluid around the system to heat the water

• Hot Water Cylinder – which stores the hot water for

– Hot water accounts for around a quarter of household energy costs and around 20 per cent of its greenhouse gas emissions

– Solar hot water systems use the power of the sun,

collected from solar panels mounted on the roof of a house to heat water for use in the bathroom, laundry, kitchen and swimming pool

Compliant?

– Solar hot water systems must achieve a minimum

energy performance of 60 per cent solar gain as

measured by the Australian Standard for solar hot

water systems AS 4234-1994 "Solar water heaters -

Domestic and heat pump - Calculation of energy

consumption"

– It is worth looking at the electric and gas-boosted

solar water heaters that achieve the performance set

down in the standard

– History on the World

• In the late 1800’s, the practice of exposing black metal water tanks to the sun was combined with

the scientific principle of the hot box, thereby

increasing the tanks' ability to collect and retain solar heat

• Clarence Kemp patented this method in 1891, and applied its principle as a means of heating water The result – the Climax – came to be known as the world's first commercial solar water heater

• 1.5 How the used of Solar Powered Hot Water?

– Domestic solar hot water systems are probably familiar

to most readers They depend on solar collectors

typically mounted on the roofs of homes The solar

collectors capture solar energy to heat water for use inside the home

– Most domestic solar hot water systems are designed to provide 40 percent to 80 percent of a household’s

annual hot water needs, although 100 percent is

possible (This requires using the most efficient solar

panels and is typically achieved in the sunniest

– Although this chapter deals with systems for

domestic hot water, these systems can also be

designed to provide space heat for homes Solar hot water systems can also be designed to heat

greenhouses and swimming pools

– They can even provide hot water for hot tubs, saving homeowners tons of money and dramatically

reducing the environmental impact of using

conventional heat sources

2.1 Save Money, Energy and Protect

Against Rising Energy Costs?

• Because domestic hot water is something we use year-round, its production is the number two energy hog in most households, behind only space heating.

• From the very first day a solar hot water system is installed, you will save money that was previously spent on fossil fuel energy.

2.2 Solar Water Heating is Green ?

• Average to produce 1 kWh of energy in a thermal

power machine used materials coal will evacuate 1kg (2.2 pounds) CO2 gas Burning natural gas and gas to produce electricity or hot water heater will be born

450 grams of CO2 gas per 1 kWh of energy generated

• For each individual household to heat hot water for

living and the average about 30% of the total amount

of CO2 Gas in households created Through equipment installed hot water heater using solar energy, devices can provide about 80% of energy needs necessary to our hot water heater, we can reduce 25% of the total CO2 Gas.

2.2 Solar Water Heating is Green ?

2.2 Solar Water Heating is Green ?

• There is no bigger long-term question facing the

global community than the threat of climate change

• Surprising as it may seem, analysts believe that the

annual total CO2 produced by residential water heaters throughout North America is roughly equal to that

produced by all of the cars and light trucks driving

around the continent.

• Another way of looking at it is: If half of all households

used solar water heaters, the reduction in CO2

emissions would be the same as doubling the

fuel-efficiency of all cars!

2.2 Solar Water Heating is Green ?

2.2 Solar Water Heating is Green ?

2.2 Solar Water Heating is Green ?

• Another important advantage of solar water heating is the fact that solar water heating produces no harmful greenhouse gas emissions.

• No carbon dioxide is ever released into the

atmosphere from a zero-carbon solar water heating system which makes it one of the cleanest energy

sources available

• Installing a solar water heater can reduce harmful

carbon dioxide emissions by 250 kg or even more,

every year Solar water heating allows you to

contribute to a much safer and healthier environment.

2.2 Solar Water Heating is Green ?

• 100% solar electric pumping eliminates the

typical 20% environmental penalty associated

with using mains electricity to run solar heating pumps and controls This means it can be

classified as a zero-carbon water heating system.

• SolartWin’s environment-centred “zero carbon”

solar water heating system design specifies a

solar electric pump So your CO2 savings won’t

retreat two steps after advancing ten That's one reason why people buy solar products from

SolartWin (And the prices are good!)

2.2 Solar Water Heating is Green ?

• To protect the earth from the global warming,

we are trying to reduce CO2 by exploiting

hydrogen energy and renewable energy like wind power, or Solar Energy which is typical Solar Hot Water.

2.3 Solar Water Heating is Reliable

• You will always have hot water even if the sun

is not shining A solar system uses your

conventional water heating system as a

backup You can use solar hot water whether you use electricity, propane, oil, or another

fuel to heat your water now

2.3 Solar Water Heating is Reliable

2.4 How to Afford SHW ?

• Using the sun's free energy to heat water helps lower your home energy bills Water heating is the second

highest energy cost in a typical household In Vermont,

a solar system can cut hot water fuel bills by two-thirds

or more.

• Depending on how much hot water you use, and your current water heating fuel, these savings can be

hundreds of dollars a year If you have a swimming

pool, solar is the most economical way to heat your

pool and extend your swimming season A solar pool heating system can pay for itself in four years or less

2.4 How to Afford SHW ?

2.5 More Hot Water …

• Because they often use two hot water tanks, solar hot water systems can increase your

household's supply of hot water, providing

you with more comfort and longer hot

showers

3 Applicatons of SHW

• Overview :

Solar energy can heat water for at least four

different applications:

1 Potable (drinking) and service use (washing) use in

homes - Solar Domestic Hot Water

2 Potable and service use in commercial, and

institutional and industrial facilities

3 Radiant Floor Heating (Space Heating)

4 Swimming pools (indoor or outdoor).

Solar Domestic Hot Water (App.)

• Solar hot water systems are most commonly used to heat water for basic household needs such as laundry, bathing, dishwashing and

cooking These systems are commonly

referred to as "domestic hot water systems

• Domestic hot water systems typically use solar energy to pre-heat the water that is incoming

to a conventionally fueled heating tank.

Solar Domestic Hot Water (App.)

Solar Domestic Hot Water (App.)

• The warmer the water from the solar heater, the less conventional fuel will be needed to provide the household's hot water needs

• During the summer months in Vermont, a

properly sized solar hot water system will

provide almost 100% of a household's needs.

• In the winter, or during extended cloudy

periods, the amount of hot water provided by the sun may be 30% or less

Solar Domestic Hot Water (App.)

• Vermont's solar hot water professionals tend

to install systems that meet between 60% and 70% of the annual load
