Talk:Direct exchange geothermal heat pump

Direct expansion heat pumps
Direct exchange heat pumps are also known as direct expansion heat pumps (Phetteplace 2007, Geothermal Heat Pumps, 'Journal of Energy and Engineering') 121.45.1.189 (talk) 12:22, 31 August 2008 (UTC)

Made page into redirect
I feel that it is unnecessary to have a separate article from geothermal heat pump. A direct exchange geothermal heat pump is just a rather small variation on the concept. In addition, direct systems are mentioned in the geothermal heat pump article. Finally, I did not move any content to the main article because most of it was not sourced. While a source was listed at the bottom of the article, most of the article's content could not be traced back to it. If someone wants to salvage material that they can find a source for, I have no objections. -- Kjkolb (talk) 07:02, 28 December 2008 (UTC)

Restored page
The article geothermal heat pump does not appreciably cover DX systems. DX is a considerably different technology and either the geothermal heat pump article would need to be extensively rewritten from the beginning to give a balanced view of the differences, or there needs to be a separate article for DX geothermal. Additionally, there is plenty of unsourced material in the geothermal heat pump article that were not removed and the redirect was not done cleanly. I will work to expand the DX article and add references, but I would appreciate it if it were left there. If someone has spare time, it would be helpful to correct the grammatical errors that have been introduced in the beginning of the geothermal heat pump article -- Jaywilson (talk) 01:34, 6 January 2009 (UTC)

Geothermal Energy category
Gorthian is absolutely right when he removed this article from "Category:Geothermal energy" and saying that "heat pumps are not considered geothermal energy, which uses deep drill holes to generate electricity". However the "Geothermal energy" category currently still lists the articles "Geothermal heat pump" and "Geothermal heating" which - following the same logic - don't belong there. Either we put "Direct exchange geothermal heat pump" back in the "Geothermal energy" category or we remove "Geothermal heat pump" and "Geothermal heating" as well. Anyone ? — Preceding unsigned comment added by Ettelaiv (talk • contribs) 17:07, 3 November 2015 (UTC)
 * The Geothermal Heat pump article has recently been renamed as Ground source heat pump after agreement that the new name avoided confusion with genuine geothermal heating system. I have just removed it, and also this article, from the Geothermal Energy category. PeterEastern (talk) 18:38, 14 June 2021 (UTC)

Merge into Ground source heat pump article?
Would it now make sense to merge this article into the main ground source heat pump article given that I it is my understanding and DX systems are now far less commonly installed due to concerns about the release of refrigerants to the atmosphere. And if these are actually more commonly installed now than I am aware of, I don't think it would over-burden the Ground source heat pump article to also cover this approach appropriately as well. Thoughts? Esp from. PeterEastern (talk) 18:31, 14 June 2021 (UTC)


 * Since ordinary GSHPs and DX GSHPs have a refrigerant side there should be no additional risk for atmospheric release. In fact one might observe that with 95+% of the refrigerant exchanger buried safely in the deep ground, there are fewer risks w DX. (Consider the longer predicted life of buried electric power versus aerial.) ChemE-EE-PE (talk) 02:31, 9 July 2023 (UTC)

Balance
I have added a 'balance' banner template to this article because much of it reads as an advocacy piece for this type of ground source heat pump without giving enough attention to the environmental concerns related to this products use of large quantise of refrigerants with the associated high global warming potential.
