With enough PV and fudging definitions to mean COP = heat output / grid input it's doable
EU Type 2 connector uses SAE J1772 signaling which has no means for the car to communicate its state of charge, so yeah, the only way to implement "ch...
Was looking for a way to measure flow and return temperatures on manifolds. Introducing the aliexpress stainless steel underfloor heating manifold, ...
Nice! I'm definitely subscribing to this 😉 I'm going to do something similar, but since I'm repiping everything, I will use manifolds with temper...
GSHP are quite similar to ASHP, differences being mostly the heat exchanger on the air or loop side, the fan, and software. In fact GSHP should be c...

LG ThermaV: It speaks Modbus, so it can be hooked up to Home Assistant with a cheap USB-RS485 dongle, local, no cloud. Besides all the reporting d...
If you tweak the lockshields you'll unbalance the rads so nope. Just TRVs open. It's a simple sanity check. If I read correctly you used to have 30l...
The tank used as volumizer behaves like a portion of extra large diameter pipe, it has negligible flow resistance and pressure drop, no worries about ...
I think recent versions of the Yonos Pico can display both pressure drop and flow rate in m3/h, if yours does that, you can check the flow will be suf...
The heat pump is humming along, I talked to the neighbors, they said they saw it but didn't hear it, asked if this thing is even on? Not even in silen...
Yeah that's the idea, it's dead simple. Personally I'd put it on return instead of flow, as the lower temperature minimizes heat loss from the tank ...
