EcoHeat Compact Heat Pump System
​
Air-source systems are the most commonly installed heat pumps. They have two parts: compressor (heat pump) and water storage tank. A refrigerant, which circulates between the two units through condenser, absorbs and releases heat as it moves back and forth.
​
New air-source heat pumps can reduce your heating costs by about 75 percent over electric heaters.
​
The Advantages of Air Source Heat Pumps
​
-
Heat pumps are much cheaper to run than direct electric heating systems. .
-
Heat pumps save space. There are no fuel storage requirements.
-
Heat pumps are safe. There is no combustion involved and no emission of potentially dangerous gases. No flues are required.
-
Require less maintenance than combustion based heating systems. They also have a longer life than combustion boilers.
How does a Heat Pump Works?
-
Heat is absorbed from the surrounding environment by evaporator. Refrigerant will completely change phase fro liquid to gaseous form.
-
The superheated gas will then be compressred further by the compressor to raise it to usable temperature and pressure before entering to the condenser.
-
Water picks up the heat and store in the calorifier tank.
-
Refrigerant liquid will travel through the thermal expansion valve and pressure will be reduced to super-cooled temperature.

Air Source Heat Pump Electricity Savings
For example - 300 liters of hot water storage tank required electricity to heat from 30°C to 60°C​:-
​
Q = cp m dT - 4.186kJ/kg°C x 300 kg x (60-30) / 3600 = 10.465 kWh
​
Given newest TNB tariff per month as follows:
​
TARIFF CATEGORY UNIT CURRENT RATE (1 JAN 2018)
Tariff A - Domestic Tariff
For the first 200 kWh (1 - 200 kWh) per monthsen/kWh21.80
For the next 100 kWh (201 - 300 kWh) per monthsen/kWh33.40
For the next 300 kWh (301 - 600 kWh) per monthsen/kWh51.60
For the next 300 kWh (601 - 900 kWh) per monthsen/kWh54.60
For the next kWh (901 kWh onwards) per monthsen/kWh57.10
​
10.465 kWh x 30 days = 313.95 kWh = 0.516 x 313.95 kWh = RM 162.00 x 12 months
= RM 1,944.00 (for water heating only)
​
EcoHeat Compact Heat Pump required power input of 0.6 kWh only and with Coefficient of Performance (COP) of 4.15 thus heating capacity is 0.6 kWh x 4.15 COP = 2.49 kWh
​
To heat 300 liters of water required 10.465 kWh and the heating time for EcoHeat Compact Heat Pump is 252 minutes therefore electric consumption is 2.52 kWh only
​
2.52 kWh x 30 days = 75.6 kWh = 0.516 x 75.6 kWh = RM 39.00 x 12 months
= RM 468.00 (for water heating only)
​
Based on above calculation, the electric saving is 75 percent.
