It's irrelevant, because you are not going to get any of that from whatever nonsense is being presented in this thread  :-//

No, but if we wanted to start a circus we now know where to find a clown  :-DD

And how is it for free if you have to, at first buy the contraption and then replace the blades every so often, and what other maintenance is needed. Nothing is for free these days.

Just as the lures for switching over to for instance a heat pump. It pays it self back in so many years they state. No it does not. After so many years you most likely have spent just as much money as you would have when you kept running your gas system. And after that so called payback period the system might need replacement because it wore out.

As it happens we are looking into another solution for heating our house, because the hassle with fire wood is becoming to much for me. For the wife it is also a bother and she finds the smell very irritating, so a solution with fuel oil or pellets is not an option. Fuel oil is also phased out, but both would be cheaper to install. Running cost would be on par with the fire wood we use now or in case of the pellets somewhat higher.

An air to water heat pomp is very uneconomical in this region due to the fact that it needs resistive heating to cope with low outside temperatures. Geo thermal is much better in performance but costs an arm and a leg to install.

We are waiting for the quotations from some companies to see the differences. We did get some insight in running cost for both types. Air to water would cost us about 2200 euro per year in electricity were as ground to water would do 970 euro per year.

Any way you turn it the comfort is going to cost us.

I'm not insisting that anything presented in this thread is practical ;) but I objected to the notion that continuous 3kW isn't worth bothering with. Yes, it won't power peak loads and you will need other sources or very restrictive scheduling, but I wouldn't be surprised if actually most consumption at most households is by loads of less than 3kW over long time.

   Not to rain on your picnic, there,....but;
   I'm wondering about regulatory stuff, boring and often unfair or unclear rules and all.

   Going into middle of stream might cause stresses on animal life nearby, like perhaps river otters, that sort of thing (that people often express that they care about.)
Pesky questions like this often get waved off.  But you could at least state that there aren't any regulatory concerns, for river beds and immediate surrounding property (even private lands).
   So, what is the waterway 'build-out' option, maybe for private lands and creeks ?   What about roads and ramps, or other access
points ?  I mean, is it simply "that's private land...don't worry." ?
   Oh yeah, (now that I got started), what about any occupational safety requirements ?  Any folks to be hired, to maintain the plant ?
Even drowning risks are taken into account when employees have to go wading, in a dynamic and possibly changing setting (seasonal rain overflows).

   I don't think a rational business and insurance person would feel 'safe and cozy' (with that 'energy' plant), without some defensive approach.
pcprogrammer:
Yes, very good points.

And what about if a tree branch gets into the water and blocks the device. By by power.

Or like the, by RJSV mentioned, seasonal effect of a sudden rain flood taking your "power plant" away because the shoring's were not good enough.
