Criteria for choosing the right brand of heat pump in Luxembourg
Renovation project, new build... To be sure of choosing the ideal brand for your new heat pump, you need to analyse a number of criteria. Here's what you need to compare:
The energy efficiency of the brand's heat pumps
Le coefficient of performance (COP) is a crucial indicator, and not all brands are equal in this respect. In Luxembourg, where winters can be harsh, give preference to a COP of at least 3.5 to ensure optimum performance even in cold weather.
Brands such as Daikin, Mitsubishi and Viessmann generally offer units that exceed a COP of 4 over the entire heating season.
Similarly, Premium brands can offer better performance at low temperatures. (below 0°C). Generally speaking, economical heat pumps offer an efficiency of 1:1 at very low temperatures (1 kWh of electricity consumed for 1 kWh of heating).
Matching the brand to the local climate
Your heat pump must be designed to operate efficiently even when the thermometer falls below zero (this is not the case for all heat pumps). Some brands are more specialised in southern European markets, others in northern European markets.
Noise level
In Luxembourg, you cannot exceed a certain decibel level at the property boundary. Opt for silent models to make sure you comply with the law.
Choose models below 40 dB(A) for the outdoor unit. Heat pumps from Saunier Duval or Mitsubishi even offer models with less than 30 dB(A).
The guarantee on different models
Like any boiler, heat pumps can break down. Compare the warranty levels offered by different manufacturers. Some offer a 2 or 3 year guarantee. Others even offer up to 10 years on their flagship models!
Availability of after-sales service
Make sure that the brand has a network of qualified technicians in Luxembourg for servicing and any repairs. This is the case for most well-known manufacturers.
Major brands such as Daikin, Atlantic and Viessmann generally have a responsive after-sales service. in Luxembourg. This is a considerable advantage in the event of a breakdown. They often have well-established dealers and repairers in the Grand Duchy.
Price range
Some brands are reputed to be expensive (premium quality materials, local production), while others are more competitive (but less well finished). A heat pump can cost anything from €6,000-8,000 to over €20,000. Choose the price range that suits your budget. (Find out more about prices)
