The Internet provides us with more information at our fingertips than any previous generation of humanity would have thought possible. This is great, but sometimes the flood of data can be overwhelming. This is particularly true on a lot of HVAC websites that give you a lot of technical data, then fall short when it comes to explaining it all. Don’t worry. We started our geothermal heat pump review series exactly for that reason.
Let’s talk about the Bosch Greensource CDi Series TW Model Geothermal Heat Pump.
You’ll probably like….
The CDi Series TW uses a scroll compressor for high efficiency operation, and was built for radiant floor heating applications.
The system meets current Energy Star and Department of Energy Residential US operating requirements.
The unit features R-410A refrigerant, dual density compressor blankets to cut operating noise, and is available in different capacities to meet different operating needs.
You can find more efficient and more durable geothermal heat pumps on the market. If you’re willing to spend a little more money, you can get a lot better annual utility savings.
The CDi Series was built with a compact footprint in mind, but that design consideration limited the available components. The compressor is, unfortunately, only single-stage, and the support systems built into the CDi Series TW could be much better.
Despite the negatives, this is not a bad geosource unit. Actually, if you’re interesting in using a geothermal heat pump in a radiant floor heating application, this is a superb choice. However, if you’re interested in a more general usage, you can find a better tool for the job.
