Hot water solutions

Current scenerio

• Majority of a building energy needs are required for airconditioning,lighting,water heating and other electrical appliances

• Considerable efforts are on for energy saving in airconditioning ,lighting and other electrical appliances.

• Hot water is one area were significant energy is consumed and has strong need for saving energy and its cost.

Hot water –current scenerio

• Large commercial buildings are using Electric resistance (geyser) water heater, with some having oil/gas/Wood fired boilers.

• Electric geysers at its best efficiency gives 0.9KW of heat energy for every 1 KW of Electricity consumed.

• Oil/Gas/Wood fired Hot water systems are also expensive and energy intensive.

The Challenge

• Heating water for everyday use is typically one of the largest use of energy .

• Nationwide large numbers of water heaters are sold in a typical year, including electric and Diesel/gas/Wood boilers.

• Given the need to reduce our Energy use and reduce CO2 emissions, the challenge is to find a better source for Hot Water.

Energy Cost

• Electricity costs are around Rs.6.00 / kw in major cities for residential, and Rs. 8.00 -10.00 / kw (including demand charges) for commercial establishments like hotels.

• Current Diesel costs are around 43/ LTR

• These costs are proving to be a major burden on consumers.

• Availability of electric power at will is also a problem in almost all parts of India

• Provision of backup DG sets involving higher costs of DG based power Rs.12.00 - Rs15 / Kw has become a normal.

Energy Conservation

• Bridge the Electricity demand – supply gap

• Efforts are required not only on the supply side but also on the demand side

• There is a need to use energy more efficiently and achieve higher level of energy and cost savings

• Heat pump water heating technology is one of the means

of achieving this.

What is Heat Pump

• The technology inside an air source heat pump water heater works on similar principles to the way a domestic fridge works.

• A device which extracts energy from air and uses it to heat water is called air to water Heap pump

Heat Pump Advantages

•Heat Pump is that it is capable of delivering energy up to 4

times of the energy it consumes.

•Heat Pump is more efficient and has upto 70 % less

running cost compared to other hot water generator.

•It will gradually substitute traditional heating facilities of fuel,

gas and electric boiler and solar heating water equipment.

•Another advantage of using Heat Pump is that it can reduce

CO2 emissions which are considered as the major cause of

global warming.

Advantage

- Heat Pumps used for heating water are highly

efficient because they tap into a limitless supply of

clean, pollution-free heat from the surrounding air.

– All you pay for is the energy to transport that heat,

unlike generation of heat by electrical resistance such

as in Geysers.

- Reserves of conventional fossil fuels are finite and

emissions of Carbon Dioxide and other greenhouse

gases add increasingly to the effects of climate change

Heat pump water Heater Principle

This principle can be hard to grasp, since it is not an immediately

obvious process. The diagram below may help to understand.

Extracted heat (2.5kW) + Power input (1kW) = The useful heat output (3.5kW)

You Gain

Geyser Principle

Available output (0.9 KW) = Electrical input (1KW )- Losses (0.1KW)

You Lose

Efficiency

• The efficiency of heat pump Water heater is measured as Coefficient of Performance (CoP).

• It is the amount of energy the heat pump produces compared to the amount of electricity needed to run the pump.

• For example, a heat pump

which uses 1kW of electricity to produce

4kW of usable energy has a CoP of 4 and

is therefore 400% efficient.

Klima vs Diesel Boiler

KLIMA Water Heating v/s Diesel Boiler

Features KLIMA Water Heating Diesel Bolier

Capacity 5000 litres per Day 5000 litres per Day

Amount of KWH/fuel requires

per day to heat water from 20 C

to 50C 54 KWH per day 25 liters of diesel per day

Approx. cost of fuel used per

day Rs 324/- @Rs 6/KWH Rs. 1075.00 for 25 liters diesel @Rs 43/-

Approx. cost of fuel used per

annum Rs 1,18,260/- 365 days X Rs. 1075.00=Rs. 3,92,375.00

Indicative system price Rs. 7,00,000.00 Rs. 4,00,000,00

Effective cost after 1st year Rs. 8,18,260.00 Rs. (4,00,000,00 + 3,92,375)= Rs. 7,92,375.00

Effective cost after 2st year Rs. 9,36,520.00 Rs. (7,92,375.00 +3,92,375)= Rs. 11,84,750.00

Total annual Savings after 2nd

year if KLIMA water heater is

installed against Diesel Boiler

392375 – 118260=

Rs. 2,74,115.00

Pay Back

• Significant increase the cost of electrical

power. That would reduce cost recovery

periods.

• Pay back can be less than 2 - 3 years

depending on the hot water usage.
