Thermodynamic panels are said to be one of the free sources of clean water with unlimited energy supply used to heat water. But its first independent test proves that they are not as efficient as thought.
Thermodynamic panels have similar panels to air-source heat pumps and they also work like refrigerators in reverse.
These panels are used to convert refrigerant into gas by making use of the heat absorbed from the atmosphere. It then passes this heat through a compressor which in turn boosts its temperature and is thereby used to heat up water. At temperatures between -20 and -30 degrees, the refrigerant enters the panel. This makes it possible for the panels to absorb warmth from the air on cold days. Claims of free hot water are false as the compressor works on electricity.
The coefficient of performance (COP) is the key metric to this kind of technology, as this measures the exact amount of heat generated per unit of electrical supply in the system.
This system was tested using a cycle that mimics the hot water usage of major family household for 7 months. The maximum monthly average COP obtained from its thermodynamic was 1.6, or 2. Bradley, the head of researchers for this project opined that initially people could say what they liked as there were no independent information. But the demand from producers became realistic right after our test went online.
A distributor of thermodynamics system also challenged how important Narec DE’s conclusions were for the industry. According to him, these conclusions were only genuine for the organization they were setup for and may have had particular problems. Llyod Hester opined that most early adopters had failed to be satisfied fully as a result of some suppliers estimating too high for these panels.
Lately, thermodynamics panels were not worthy of being chosen for the renewable heat incentive. These Renewable Heat Incentives are government bodies with the responsibility of proffering financial encouragement for low carbon heating technologies which is liable to change.
The main requirement and standard for RHI is that the product must be approved by an organization known as Micro generation Certification Scheme. Late last year November, the MCS gave additional information in terms of its requirement as regards thermodynamics panels for hot water.
Many producers are still in the process to meet up with the certification, as none has been able to. According to the Department of Energy and Climate Change any change as regards the RHI will be determined depending on the reassessment in November and panels will have to attain at least lowest seasonal evaluation where the average COP over the complete heating season is 2.5 to be qualified. Property owners will certainly want to confirm that these panels are part of the scheme
According to Bradley, “thermodynamics is a technology which is still in development and in subsequent time, the result will be amazing”. In the meantime, he recommends some sustainable choices for domestic heating, like solar water heating, which makes use of well tested technology known by the installers.
