I will, good idea !

Thank you for you insight - Probably best is to act locally and or use charity association to be more efficient for other countries. It is sad sometime some people use charity or assiociation to push things that makes the work of the good one even more difficult

Thank you for the answer - I think one the biggest trap is to bring more problem than solution. I am afraid that a some laptops or smartphone that I gave a second life will have almost no value on the second hand market. I will keep offering them locally on market place or charity shops

I have old electronics, including macbook that I would like to give is there a way or an assiociation to know how ?

My two cents, I just tried to show this free course on my site, because heat pumps are an interesting topic. There is also others courses like this : https://hvac-learning.com/courses/air-handling-units-technol...

Heat pump as every heating or cooling devices, have pro and cons. This is where HVAC knowledge is nice to have, in order to have the best solutions. For example, the maintenance / obsolescence are an under estimated point when it comes to environment and savings

As others comments said, it depends on the climate : The problem is that the power/performance of the heat pumps decreases with the cold weather and the necessary increase in the temperature of the heating water, which obliges to keep the boiler for the cold weather. This is a problem for the heat pumps without probable solution and little progress to wait. The solution is to insulate the house very well so that its needs can be covered by the heat pump with less hot water. Divide the losses by 2 at least.

For the record, I am only trying to make my elearning website more known. There is plenty of other HVAC subject that I would like to share. It's just that Heat Pump where for me an interesting topics to get into the subject but you can have a look at other free courses.

I am sorry for the inconvenience. I am still learning how to build a nice and efficient website. I will analyze what happened and try to fix and enhance !

If you have advice for me, I'll take it ;) can exchange with HVAC courses

The website is new and not fit yet for such numbers of visit, so sometimes it does not render well pages. I(admin) still in the process of understanding how to build a nice website. I will analyze what happened and enhance it. I'm sorry for the inconvenience !

I think this is possible. I will ask to a teacher of hvac-learning and come back to you asap. But basically you can heat water instead of air with a heat pump.

The site is pretty new, I(admin) am not used to have lots of traffic. I will analyze what happened and chose better solution. I am sorry for the inconvenience !

The site is pretty new, I am the webmaster, maybe I should analyze the log and choose better hosting. I am sorry about the inconvenience!

The heat pumps are one of the means of heating (and air conditioning) in the heart of the news. What is their principle of operation. You can ask questions here if there are points to clarify in the course
