performance coefficient<\/a>). <\/strong>Or in other publications written by competent specialists.<\/p>\nIn short:<\/p>\n
\u201cTest results for the best systems are around 4.5. When measuring units installed over a full season and taking into account the energy required to pump water through the piping systems, seasonal COPs for heating are around 3.5 or less. This indicates that there is room for further improvement.\u201d<\/span>.<\/p>\n13 kW heating power with 0.23 kW consumption? A dangerous joke<\/h2>\n
According to the data sheet:<\/p>\n
\n- \n
The heating power is 13 kW.<\/p>\n<\/li>\n
- \n
The electrical power absorbed is between 0.23 and 1.81 kW (!)<\/p>\n<\/li>\n<\/ul>\n
This is mathematically impossible<\/strong>:<\/p>\n\n- \n
13 kW divided by 0.23 kW = COP of 56.5 (!) \u2013 which goes against the laws of thermodynamics.<\/p>\n<\/li>\n
- \n
In reality, a 13 kW pump needs at least 2.5 \u2013 3.5 kW<\/strong> to operate efficiently at a PREMIUM class. Real is 4 kW consumption.<\/p>\n<\/li>\n<\/ul>\nMarketing exaggerations that hide reality<\/h3>\n
These unrealistic data are designed to attract naive customers<\/strong>, who don't understand how a heat pump works:<\/p>\n\n- \n
The actual COP depends on the temperature difference between air and water.<\/p>\n<\/li>\n
- \n
At 26\u00b0C air \/ 26\u00b0C water, there is almost no significant heat transfer, so the data is irrelevant.<\/p>\n<\/li>\n
- \n
No one uses a heat pump to keep water at air temperature.<\/p>\n<\/li>\n<\/ul>\n
Who is affected by these marketing exaggerations?<\/h2>\n\n- \n
End customers<\/strong> \u2014 who may be disappointed after installation, noticing that electricity bills are higher than the technical data sheet promises.<\/p>\n<\/li>\n- \n
Serious installers and distributors<\/strong> \u2014 which must explain why the "miracle" in the brochure doesn't happen in reality.<\/p>\n<\/li>\n- \n
The entire industry<\/strong> \u2014 because such marketing exaggerations undermine confidence in heat pump technology.<\/p>\n<\/li>\n<\/ol>\n
\nWhat to check before buying a pool heat pump?<\/h2>\n
\u2705 Real date to test<\/strong> \u2013 independent certificate (e.g. EN14511)
\u2705 COP at real external temperatures<\/strong> \u2013 for example: air 15\u00b0C, water 26\u00b0C
\u2705 Electrical power absorbed<\/strong> \u2013 not to differ by 1000% from what is delivered
\u2705 Manufacturer transparency<\/strong> \u2013 does it provide real technical reports?<\/p>\n
\nConclusion: Be careful of impossible promises<\/h2>\n
The Model NNN pump may perform well under some conditions, but the data in the specifications is misleading and exaggerated<\/strong>. COPs of 10+ in air-water are marketing hype, fantasy, but not technical reality. Don't be fooled by spectacular numbers \u2014 always ask real evidence<\/strong>.<\/p>\n
