  1. Well, the closer you run the water to room temperature the higher the COP, just like your frige will draw less power the hotter you set it to.

  2. To answer your question as short as possible, it is 800% efficient at turning electricity into heat, but it is 93.75% efficient at moving heat from the outside to the inside)

  3. ​ @lucbloom There are certain physical limits, you cannot cheat the laws of physics. But, I think for aircraft where cost is less of an issue, pressurized cooled hydrogen will probably be the answer.

  4. Ehm...no, weather compensation is ALWAYS needed, we run anywhere from 22 degrees flow temp to 32 degrees flow temp, and we have 30 cm rock wool in all of our walls, 80 cm in the roof and a well insulated concrete slabb, we have a average SCOP of 4.2 with hot water using a borehole heatpump (drilled to 200 meters), we live at 63.5 degrees North, winters are cold.

  5. Don Kruger is asking for you.

  6. Over 20 years? Hell yea, over 10 years, depends, over 5 years is very hard. Anyhow it will influcence the property price greatly, it is an IT factor that can make a property jump from old and neglected to the renovated and in demand category.

  7.  @123_1  Installing a heatpump properly is a fundamental investment, it is not as simple as you might think if you strive for high heating efficiency.

  8. In the Nordics we use 200 meter deep boreholes instead, costs 5,000 Euros to drill but the savings are INSANE, literally 50% cheaper to maintain and buy electricity compared to oil, which is the only alternative up here. (Heating oil is still close to tax free here, so it is not expensive)

  9. Gas plants are on the way out long term, so it is not a concern of the private house owners.

  10. Cold hands, runny nose, dry eyes, condensation on the walls, do I need to say more? Dropping the temperature inside is not good, anything below 19-20 C other than for bedtime is bad for you, especially elderly, children and sick people.

  11.  @matthiaswille8641  Can you though? The food would not last...neither would you be comfortable with 13-15 degree inside temp. realistic scenarios is the SCOP value, did you even watch the video or are you just commenting on the topic?

  12. @purpleblueunicorn  Probably saved something like 1-2 dollars, cycling it extremely wasteful.

  13. @matthiaswille8641  That is why you need to watch the video, they clearly said the realistic value over a year is 5.0 S.C.O.P...or 500%

  14.  @goncaloaraujo6644  Try sitting in a 15 C room with normal T-shirt and sweaters...

  15.  @goncaloaraujo6644  So reverting to old ages, why not invest in insulation instead and be comfortable?

  16.  @goncaloaraujo6644  Well, you save money in the long term, if you can't afford it you might have to think about downsizing until you have enough money to live comfortably in a large house.

  17. Here we do 32 degree flow temp (negative 10-20 C outside) with underfloor heating (Our houses are well insulated, 30 cm of rock wool in the walls, 80 cm in the roof and tripple pane glass windows.)

  18. Yea, technically the heat pump is 93.5% efficient at moving heat in that case, that is the real number.
    1
  19. @bringiton8989  That is in fall/summer when outside temps are above 19 Celsius, we have whole house floor heating. In winter we run on average 26-28 C

  20. True, gas and oil seems cheap, but it has other costs (dependent on fossil fuel sources, polluting your local enviroment, gas leaks are health hazard and fire hazard and explosion hazard, oil spills are enviromental hazards and health hazards if you have wells etc. not to mention global warming....)

  21. Ahaa, so my 23 degrees is not the same as your 23 degrees? Interesting.

  22. @Alex_441  Not a messurable amount, the sun radiates 500,000-1,000,000 kW per square kilometre, a heatpump moving 3-5 kW is not much compared to it.

  23.  @izalman  Naah, you will reduce your carbon footprint by a large factor AND save money in the long run, also be just as warm and comfortable as with any other system, to make it comfortable you need either more radiators or infloor heating.

  24. No, they can do it, they just want to hold you upside down and shake out every last penny you have to do it to your house ;)

  25. Because it is cheap, easy to do and costs little if you plan for it BEFORE you build, and even after the fact only the heavy weight options are expensive (adding more radiators or a larger pump)

  26. That is where UV lights in tanks comes in, big investment but pays off in lower tank temps.

  27.  @bibihunden  It is, but they last a long time, so for a new build it is recommended, having a huge tank with 42 degree water is perfect to get a high efficiency for the heating of it.

  28. Gas is is bad for global warming, explosion hazard, health hazard (leaks of the gas and exhaust pollution), another monthly bill for the connection AND not forever.... The investment not only is benefitial for heating costs...it also raises property prises AND quality of life.

  29. @stanleytolle416  No, you don't...better to have a generator if you are paranoid, gas is not good to have in a residential building period, cost to have it even if you never use it. Sure, but you never get rid of the health hazard, explosion hazard, pollution etc. by keeping the gas...

  30.  @katiegreene3960  No, the video is about air source I believe
