Ranking of Air-to-Water Heat Pumps
In this section, the speaker provides a ranking of air-to-water heat pumps with 11 to 14 kW power. The speaker also includes additional brands requested by viewers and explains how he selected the models for the ranking.
Brands Included in the Ranking
- The ranking includes brands such as Blaupunkt, Panasonic, Aquarea T-Cap, Rotex, Brötje, Alpha Innotec, and Nobelan.
- Teccalor, Bosch, and Dimplex were not included in the ranking because they did not provide COP values.
Results of the Ranking
- The Polish brand Blaupunkt had a consumption rate of 6,807 kWh per year.
- Panasonic had a consumption rate of 6,928 kWh per year.
- Rotex had a consumption rate of 6,963 kWh per year.
- Brötje's BLW Neo 12 was found to be equivalent to Heliotherm's model but was seven decibels louder.
- All models ranked above consumed more than 6,750 kWh per year.
Additional Brands Requested by Viewers
In this section, the speaker discusses additional brands that viewers have requested but were not included in the previous ranking due to lack of COP values.
Ochsner Erhard 518
- Ochsner is an Austrian company that has achieved €100 million in revenue.
- Their Erhard 518 model was mentioned but no further details were provided.
Comparison Between Different Models from Same Manufacturer
In this section, the speaker compares different models from Heliotherm and shows how their efficiency can vary significantly even within one manufacturer's product line.
Heliotherm Models
- The speaker compares Heliotherm's 14 kW S14L-Cover, 10 kW HP12L-BC, and 12 kW S12L-CC models.
- The HP12L-BC was found to be particularly quiet.
- The S14L-Cover had poor efficiency compared to the other two models.
Importance of Choosing the Right Model
In this section, the speaker emphasizes the importance of choosing the right model for your needs and highlights how even small differences in model numbers can lead to significant differences in performance.
Alpha Innotec LW 161 HL-V vs. Nobelan LI 16.1 HLV
- The Alpha Innotec LW 161 HL-V is a better fit for this category than the Nobelan LI 16.1 HLV despite having similar names.
- It is important to pay attention to individual model numbers when selecting a heat pump.
Conclusion and Call-to-Action
In this section, the speaker concludes by thanking viewers for their support and encourages them to subscribe to his channel. He also introduces his new heat pump calculator based on EU-Norm EN14825 and invites viewers to test it out as beta users.
Heat Pump Calculator
- The new calculator is based on EU-Norm EN14825.
- Viewers are invited to test it out as beta users.
Call-to-action
- Viewers are encouraged to subscribe to the channel in order to help it reach decision-makers in the industry.
Overview of Heat Pumps
The speaker discusses three companies that manufacture heat pumps and compares their products. He also introduces the concept of COP (Coefficient of Performance) and explains how it is used to measure efficiency.
Companies that Manufacture Heat Pumps
- Solar Focus, a company in Steyr, Austria
- Kronotherm, a Slovenian company
- M-Tech, a small company located near Linz, Austria
Comparison of Heat Pump Efficiency
- Ochsner's heat pump is comparable to Daikin's.
- Windhager's heat pump is slightly more efficient and quieter than Ochsner's.
- Waterkotte's heat pump is relatively loud.
- Solar Focus' Vampir heat pump is significantly quieter than Waterkotte's.
- M-Tech uses r452b as its refrigerant and has similar efficiency to Chronotherm.
COP and Efficiency Measurements
- COP (Coefficient of Performance) measures the efficiency of a heat pump under laboratory conditions for specific operating points. It does not take into account the use of auxiliary heating elements in winter.
- The new norm EN14825 measures seasonal COP values divided by primary energy factors to determine energy efficiency.
- The speaker created an algorithm using these values for his simplified heat pump calculator.
Ranking Heat Pumps by Efficiency
- The speaker ranked 15 different heat pumps based on their COP values according to EN14511 and ETA values according to EN14825.
- Three pumps moved up in rank when considering ETA values instead of just COP values.
Overview of Wärmepumpenbetrieb
In this section, the speaker discusses the importance of experience and the type of refrigerant used in heat pumps. They also mention that R410A will be banned from 2025 and will receive a deduction of 10 points. The use of R290 is supported with an additional subsidy in Germany, which earns it 10 extra points.
Kältemittel
- R410A will be banned from 2025 and will receive a deduction of 10 points.
- The use of R290 is supported with an additional subsidy in Germany, which earns it 10 extra points.
- Refrigerants with high greenhouse gas potential receive a deduction of five points.
- R454c is neutral.
Champions League for Luft Wasserwärmepumpen
In this section, the speaker presents their evaluation of air-water heat pumps ranging from 7 to 24 kW. They focus on efficiency and highlight that smaller innovative manufacturers outperform larger corporations.
Top Air-Water Heat Pumps
- Smaller innovative manufacturers outperform larger corporations in terms of efficiency.
- When weighting ETA55 more heavily and including criteria such as noise emissions and refrigerant used, nine out of ten companies remain in the top rankings. Only Vaillant drops to tenth place.
- Top companies are not only efficient but also quiet, many have already switched to propane.
New Rechner
In this section, the speaker introduces their new computer program based on new standards. They invite viewers to help test the program and provide feedback.
New Rechner
- The new computer program is based on new standards and is still undergoing testing.
- Viewers can help test the program by emailing youtube@bonotos.com to receive a pre-release version of the software. However, there are limited copies available.
- The speaker sees storage technology and hydraulics as the biggest challenges in this area.
Conclusion
The speaker concludes by thanking viewers for watching and encourages them to subscribe. They also mention that they will be working on a new video about storage technology and hydraulics.
