Hi supdood,
----------------------------------------a friend of mine installed a thermodynamic water heater in his condo (see https://www.dedietrich-heating.com/news2/thermodynamic_water_heater). It is really efficient. Since I have a solar water heater, I do not have the needs for it, otherwise I would put all my machines in a small room in the basement beside such a thermodynamic heater. Cheers, Yves |

Adding 'code'-tags improves the lot a bit:

@KerSampson Thanks for sharing that. I looked into getting a heat pump or hybrid water heater (as we call them in the US) but am waiting a few years in the hopes of installing a whole house heat pump system that will include indirect hot water heating. The GHG reduction incentive scheme in my state is also a bit skewed; there are no incentives for switching from gas to heat pump for hot water.
----------------------------------------I'm curious if anyone has thought of integrating this into some cyclical living: Solar PV electricity --> WCG computations --> waste heat collected by water heater --> grey water diverted to vegetable garden --> food scraps to compost --> compost as garden fertilizer. |

Thank you Adri. I learned something, so the next time I need to do this I can do it better.

As they say in Dutch: 'Graag gedaan' (= You're welcome / My pleasure), Sgt.Joe.

Why not a pre heater tank in front of the water heater to dump system heat into?
----------------------------------------I think that would compliment solar water heating by taking the "chill" out of the water before it goes to the solar heated system. [Edit 1 times, last edit by Former Member at Aug 26, 2020 2:56:49 AM] |

Hi gta198,
----------------------------------------it is exactly what I am considering to implement. Maybe with a switching: 1/ Summer: pre-heating with computer heat, final heating with solar 2/ Winter: pre-heating with solar, final heating with computer heat. I do even consider to "recycle" the computer heat into the central heating system during winter time. It shall be exactly calculated since the investment is not really cheap. Cheers, Yves |

In the winter wind is more cost efficient than solar in most places. In summer which is best is a toss up depending where you live. A plus with wind is that you can use a water heater element as the shunt or dummy load when the batteries are fully charged.

A user posted about his costs of today and why he is stopping crunching.
https://www.worldcommunitygrid.org/forums/wcg/viewpostinthread?post=674165 Here is an update for where I am in Quebec Canada where all electricity is hydro. The 1st 40 kWh: 0.06319 CAD --> 0.0481 EUR, 0.0487 USD, 0.0411 GBP The rest kWh: 0.09749 CAD --> 0.7417 EUR, 0.0749 USD, 0.0630 GBP |
