@@corymac By the way, the added benefit of using a heat pump is that in summer I can reverse it and cool the water. That water can then be circulated in the floor heating pipes to do radiant cooling.

[@NotoriousPyro]

I wish all engineers took such pride in their work. I bought a house where the gas installer seemed to be the most lazy half-assed engineer in the world: leaky and damaged radiator bleed valves causing pressure loss (previous homeowner thought it was normal), terrible soldering (really sloppy and all down the copper, far too much used), uninsulated pipes, pipes too thin & bent instead of using corner joints, pipes too close to floorboards causing creaky floors. Then I had an install of a heat pump to turn it into a hybrid system, and they decided to neglect insulating the pipes on the lower floor, just because they couldn't access them - but they didn't tell me this, they just threw the insulation in the loft... Not only this but the heat pump installer said pressure loss is normal also!!! I've been slowly correcting the mistakes...

[@corymac]

Ahh thank you! And sorry to here that!!! Yes, unfortunately I find sloppy work on the regular 😔. A lot of people take no pride

Just commenting about the A1 and A2 going through the thermostat and overload (16:45). As you know because you literally pointed it out in the video- You only need to run either the wire going to A1 or A2 to break the circuit to the coil in the contactor through the switches. I always break A1 which is the phase the systems I build and connect the neutral to A2 or if it is 24v it is G to A1 and G0 to A2 or 24v+ A1 and 24v- A2 depending on the coil voltage on the contactor/relay.

As long as it is a stranded wire you have to put ferrules on it when its a screwed connection

[@alt3241]

You often do not need to involve a inverter to take power from solar panels for powering a resistance load for heating as only a duty cycle limit to keep the resistance element from overheating ( melting ) and a thermostat to limit heated material ( in this case water ) from overheating ( in this case water from boiling and then causing a steam explosion ) . A bimetallic thermostat switch may have a maximum current but no minimum current and its lifespan is enhanced by use of low voltage and current through transistor controlling ( with snubber protection) the power to a relay ( usually called a contacter ? ) multipole single throw relay ) ) thus no need for the exorbitant expense of inverters for heating .

[@corymac]

These aren’t inverters, they’re diverters. They have the inverters on the home anyways, these just track the excess power and send it to the heating rather than exporting ( wasting ) it

[@Andy100ElectricAndy]

I’ve since worked out the relay function is next to useless on the Eddi. Relay had very limited control and its logic of treating surplus and 3rd party divert is different to EDDI and Zappi. Maybe that why the customer paid for 3 eddis.

It really is easier than it looks! Eddi’s are great

[@mistermartin82]

whats the difference between a contactor and a relay? they sound like they are very much the same, except maybe the contactor latches

[@corymac]

Very similar, relays are used to control circuit contacts due to set parameters or conditions. Contactors are used more to interrupt or establish connections repeatedly under various conditions. More common in 3 phase

[@Chillielectrical]

Not always, but generally off-the-shelf contactors have AC coils and relays have DC coils.

Normal 13A single phase immersion heater timers just use a relay instead of a contactor. Is that immersion heater > 13A per phase?

[@Chillielectrical]

Yeah, this immersion element is somewhere between 14-16A per phase. Eddi can control the output current to a maximum of 16A / 3.68kW 😅
