When it comes to heating and cooling your home, one of the most energy-efficient options is a heat pump. Heat pumps provide both heating and air conditioning in one system by moving heat rather than generating it.
This makes them much more efficient than furnaces or air conditioners. Two of the top brands for heat pumps are Mitsubishi and Bosch. But which one is right for your home?
In this comprehensive guide, we’ll compare Mitsubishi and Bosch heat pump models on key factors like efficiency, features, noise levels, and warranties.
We’ll also provide pros and cons for each brand and a FAQ on heat pump basics. Read on to learn which brand is the best choice for heating and cooling your home.
| Feature | Mitsubishi | Bosch |
| Efficiency (SEER/HSPF) | Up to 24/12.5 | Up to 19/10 |
| Compressor Warranty | 10 years | 5 years |
| Noise Levels | As low as 44 dB | Around 63 dB |
| Zoning Capabilities | More size options | Limited options |
| Smart Controls | Third party compatible | bosch-climate.com platform |
Key Takeaways:
- Both Mitsubishi and Bosch offer premium heat pumps with excellent efficiency ratings and features.
- Mitsubishi tends to edge out Bosch in peak efficiency, zoning capabilities, noise levels, and compressor warranty coverage.
- Bosch counters with renowned German engineering, integrated smart controls, and environmentally friendly options.
- There is no universally “best” brand. The right heat pump depends on your home’s needs and which features are most important.
- Work with an experienced contractor to evaluate your climate control requirements and recommend the optimal system for your home.
- With proper installation and maintenance, Mitsubishi and Bosch heat pumps can provide 15-20 years or more of reliable performance.
Key Differences Between Mitsubishi And Bosch Heat Pumps
Efficiency Ratings: SEER and HSPF
One of the most important factors to compare is efficiency ratings. For cooling, heat pumps are rated by Seasonal Energy Efficiency Ratio (SEER). For heating, they are rated by Heating Seasonal Performance Factor (HSPF).
The higher these numbers, the more efficient the system.
Both Mitsubishi and Bosch offer options with excellent efficiency ratings. Mitsubishi’s highest ratings are up to 24 SEER and 12.5 HSPF. Bosch offers up to 19 SEER and 10 HSPF.
However, Mitsubishi tends to have more size options that meet the highest tier levels. So for maximum efficiency, Mitsubishi edges out Bosch.
Available Features
When choosing a heat pump, you’ll also want to consider features and functionality. Key features to compare include:
- Variable speed inverter compressors – Ramp up or down based on demand for more consistent temperatures
- Zoned systems – Control temperatures in different areas of your home
- Smart/Wi-Fi controls – Remote access and automation through your smartphone
- Silent modes – Reduce outdoor unit noise during certain hours
For variable speed compressors, both Mitsubishi and Bosch offer excellent inverter-driven options across all models. For zoning, Mitsubishi offers more size options for multi-zone systems. Bosch’s zoning options are more limited.
For smart controls, Mitsubishi works with third party smart home platforms. Bosch has its own integrated solution called bosch-climate.com. So for controls, it’s a matter of whether you want an open-platform or single-brand experience.
Both brands also offer silent modes to reduce outdoor noise during early morning/late evening hours. Overall there are some differences in features, but both brands offer robust options to customize your system.
Noise Levels
A major concern with any heat pump is outdoor unit noise disrupting your home life.
Both Bosch and Mitsubishi use advanced fan designs and insulated compressors to reduce noise.
However, independent testing shows Mitsubishi units operate quieter on average.
For example, Consumer Reports testing found the Mitsubishi MUZ-FH15NAH had noise levels as low as 44 decibels in cooling mode.
Comparable Bosch unit BST1500XN was louder at 63 decibels.
Mitsubishi also offers a “silent mode” to further reduce noise during key hours. So for the quietest outdoor unit, Mitsubishi is the winner.
Warranties
The warranty terms give a good indication of the expected reliability and lifespan of these systems. Both brands offer strong coverage that reflects their premium status:
- Mitsubishi: Parts and compressor 10 years, other components 5 years
- Bosch: Parts 10 years, compressor 5 years
Mitsubishi offers a longer warranty on the compressor, which is the heart of the heat pump system. The longer 10 year coverage suggests great faith in the reliability of their compressors.
Bosch still offers strong coverage at 5 years. Overall warranty terms are a bit stronger with Mitsubishi.
Pros of Mitsubishi Heat Pumps
Now that we’ve compared some key factors, let’s summarize the main advantages of choosing Mitsubishi:
- Exceptional efficiency ratings – Up to 24 SEER and 12.5 SEER across multiple model lines
- Ultra-quiet performance – As low as 44 decibels based on third party testing
- Zoning capabilities – More size options for custom whole-home comfort
- Strong warranties – 10 years on parts and compressor
- Smart controls integration – Compatible with third party automation systems
Mitsubishi is clearly positioned as a premium offering with great energy savings potential, quiet operation, and robust warranty coverage. If you want best-in-class efficiency and noise levels, Mitsubishi is likely the better choice.
Pros of Bosch Heat Pumps
What are the key benefits of choosing Bosch? Here are some of the brand’s strengths:
- German engineering and quality – Bosch is known for outstanding engineering and rigorous testing in HVAC equipment. You can expect great durability and performance.
- Integrated smart controls – bosch-climate.com provides control through an elegant single-brand platform.
- Flexible maintenance plans – Options like parts coverage and labor discounts provide budget stability.
- Optional Greensource® models – These use an ozone-safe R410A refrigerant with lower global warming potential.
- Bosch reputation – The Bosch brand commands respect for quality AC systems. You’ll get great product support.
In summary, Bosch is a premium HVAC brand that offers time-tested reliability, integrated smart controls, and environmentally friendly options. For some homeowners, the Bosch name provides great peace of mind.
