We have big wind farms all around us and solar is growing very rapidly, in spite of continued interference from the fossil fuel industry and their allies.
    Eddie and I counted them there's only 9,999 lakes.

    Do your heat pumps utilize the tubing that is buried in the ground that the air circulates through to heat and cool? A friend was going to install this type system in his house, many years ago. We lost contact so I don't know if he did it and/or how it worked out for him.
    Heat pump or geothermal or same thing? Science, maaaan.

    Some have piping in the ground specially new build homes, where ground works have to be done anyway.
    Existing build homes have a specialised drilling company sink a pipe 80 meters deep or deeper ( 240 feet) and use that as heat source, te deeper you go the warmer the underground is.
    Drilling is more expensive as just put piping in the ground, but in the end it still is cheaper, though the roi is longer.
    Some new systems have just an outdoor unit that uses the outdoor air as source, even when it freezes it seems to be able to supply heat.
    Seen one of those installed in a neighborhood near me last year, asked the peeps what it was, thought it was a newfangled airco....

    Our old electric hot water heater decided to go tits up on us a couple weeks ago during college finals. One option we had available was a hot water heater that works like a heat pump but for heating just water. Looked like a great idea till I realized all the retrofitting of the area would be way out of budget even though the unit itself would've only run about $550 after incentives. So the old style went back in and since this technically isn't my house I gave it no more thought except that I thought it a good technology to implement. Next house....yeah.

    Like that post was...
    Moving on, my posts are not helpful

    Investment only pays off if it is your own home, and you will keep living there for some time.
    Selling a house here comes with a energy certificate, depending on how well the house is insulated, and other stuff installed to keep energy costs and use down.

    With solar panels, hat pump and some warm water panels on the roof most here can be close to 0 energy users, depending on the solar panels and number of them they even deliver energy back into the mains.

    My energy use cost me 100 euro a month, gas and electricity, so my r.o.i. would be too long, and the house is rented as well.
    So i save in other means, getting as AA++ energy efficient stuff - see plasma out, UHD LCD in, and next is the washing machine when it goes tits up.
    Looking at the weekly use i got the electricity use back from 4000 KW/H to 2500 KW/H a year.

    We have a few people using geothermal here. Most installations involve drilling multiple wells, which is obviously not inexpensive. The ground freezes here to a depth of 8 feet, which makes shallow buried systems unusable. But one friend of mine who has geothermal brags about how small his energy bills are, with solar providing nearly all the required energy, even in our very cold winters.

    You mean this thing, Cor? (Kinda hard to see from 18,000 feet). But they stretch out in large patches.


    Edit: A bit off topic, but the vertical climb of the Airbus 330-300 is impressive.

    Look near the engine, and off in the distance too.
