Normally, sensible people would get air-to-water heatpump to heat both the house, and DHW. For hot water only, quite obviously it will not make any sense, unless you are running a public bath.

Wood for cooking is often for a specific flavor, that factor alone makes the specific kind of wood far more expensive than general purpose firewood.

For just hot water, a much smaller and cheaper heat pump will do.

We already talked about that. That starts at 12K for the equipment, new floor, new paint + finish for the walls, several months installation time, entirely new heating system. That ballpark 50K, not 3.5K. The one for 3.5K doesn't even support heating.

This is one weird discussion. One can easily miss the fact that you are here just trolling, and accidentally take you seriously, like I did. It is unfruitful to discuss a case where a product which is completely unsuitable for your use case and just throw around ridiculous numbers when you force-fit it. Why stop at 50k, why not ten thousand million trillion billion? In reality, you just should do something else and not even consider air-to-water heatpump for your case.

People usually assume you are being sensible and honest, and don't want to read tens of pages of wall-of-text to find something that shows you were not. From now on, you are ignored by me on this thread so the mistake won't happen again.

This can be true, but it often feels like they are using the most bizarre wood for no good reason. Like the use of mesquite for barbeques in Arizona. Mesquite is a tree that grows in the desert, and has very dense hard wood. Growing in the desert, you can imagine how long it takes to grow big enough to be harvested, and tossed on the fire.
