Home Electrification: There's not a lot to do, and it doesn't have to be hard (Part 1)

@TechConnectify My dad has been installing electric baseboard heating in all the trailers at the park as he goes through for renovation. The vast majority never order propane anyways and relied on plug in space heaters.

He figured if that was happening anyways it might as well be done more safely. It's a bit more expensive to heat with electricity here but people really value simple billing.

@TechConnectify My trailer doesn't even have the furnace anymore, I wasn't using it so I just pulled it out so I could have another closet.
@TechConnectify
How would Chinese restaurants operate without natural gas? Because they require something that heats up very fast in order to cook the food in that manner. Have they come up with any electric alternative to those large burners that can crank out the heat so quickly?
@Bringiton Yes, induction woks are a thing. They're expensive like any new technology, but they're here.
@TechConnectify
I actually saw a video where a woman was talking about induction heating and induction woks. But I have no idea it they would be practical in say a Chinese restaurant...
@Bringiton @TechConnectify if we get fossil fuel usage down to only Chinese restaurants I think we will be doing pretty good.
@jesses @Bringiton heh, that's also true! And they can always use bottled propane
@TechConnectify i am 4 major gas appliances. the biggest problem is they are all pretty new. so when i replace them, i’ll probably go electric. but that is probably 10-20 years out :(
@TechConnectify The problem is not rooftop solar but net metering. In Belgium, we have different meters for import/export and we pay "distribution costs" only for the energy we import form the grid. The mean reasoning is that the consumer pays the cost to get energy from point A to point B and not the generator. This solves the account problem and grid-upkeep cost. You need to have a look over the pond to see how it is done there. TL;DR, rooftop PV is not the problem, but net-metering is.
@TechConnectify Gas powered clothes dryers? 🤯 😱
@wolfensteijn Yep! Though, they still use electricity to spin the drum and run the blowers and stuff. The gas is just to generate heat.

@TechConnectify The idea of having a flame close to fabric and lint seems so stupidly dangerous.

But I guess that is just my European upbringing 🤣

@wolfensteijn Well, there is a heat exchange so it's not like there are open flames, but there definitely is a risk of fire from lint buildup in the vent pipe.

I'm not actually sure if the risk is any greater than with a conventional electric dryer, though. I'd need to look for data on that.

@TechConnectify The way forward for dryers would be heat pump dryers anyway.

I am reading some interesting bits about "mechanical steam compression dryers" which apparantly are another efficiency step up.

And I hadn't said it before, but interesting video. Cool to see what the options for full electric living are on the other side of the pond.

@TechConnectify @wolfensteijn Is there a heat exchanger? I believe they're just direct fired, which doesn't matter because the the air in the dryer is vented outside the home. (Not that people with gas stoves seem to care about direct fired appliances in their living space).
@wolfensteijn @TechConnectify I don't think it's any more or less dangerous than having a hot heating element (which is the alternative).

@TechConnectify @wolfensteijn That's the bit I thought was weird too.

We almost never use a clothes drier. In summer there's an outdoor washing line, in winter there's one of these:

@TimWardCam @TechConnectify I know me, and using a drying rack or outside lines will mean I won't have dry clothes when I need them.

So I did go the easy route, and got myself a second hand condenser dryer, and that has been game changing for me.

@wolfensteijn @TechConnectify Yeah, you do need all of (1) enough space for the rack, and (2) enough money to own an extra couple of days' clothes, and (3) a tiny (but it is only tiny) amount of planning.

Edit to add: actually (2) probably costs less than the fuel for running a clothes drier.

@TimWardCam @TechConnectify @wolfensteijn That may be a possibility but there's something to be said about the convenience of just taking your wad of laundry and tossing it in the dryer. Costs more, but much faster and easier. It's a trade-off

@wolfensteijn @TechConnectify Just purchased a gas dryer a couple of years ago. $100 USD premium for the gas model, but worth it for the cost savings in running the dryer.

We have replacement homes being built in the area, they all have clearly labeled gas exhausts. Gas isn’t going away.

@russes @TechConnectify Gas should go away! Though the timeline on which it does that will depend on location and other factors.

New housing and building developments in my country are without a gas line by default. And there are lot of projects for replacing existing gas lines with alternatives. Mostly for heating, since cooking can be done quite efficiently on induction stoves.

And that in a country that had cheap gas, because we had our own supply. Which is being shut down now.

@wolfensteijn @russes @TechConnectify I’ll keep my Gas, thank you. The nice thing about Gas is the furnace/water/dryer are an open solution. I can obtain service & replacements easily.

I’m replying from an all-electric home. In cold weather, the heat pump is useless & I run the fireplace to offset the “auxiliary” heat. I’m also at the mercy of a proprietary heating system & my HVAC contractor.

@TechConnectify re: net metering. Germany: Subsidies already close to zero, grid prices through the roof (0,40€+/kWh), so very big incentive to consume your own energy and store the rest in a smallish battery for overnight usage.

@TechConnectify Just about to move to a house that needs a deep retrofit, so this is relevant to my interests.

Thanks for focussing on these kind of techs, it really helps reduce intimidation for people who are willing but otherwise ignorant. Plus highly interesting and entertaining in general!

@TechConnectify I was looking into it. The issue I found (and the reason I'll likely update the gas boiler) is that heat pump requires a really good insulation, which I currently don't have and adds a lot to the retrofit bill, and also since it heats water at lower temperature I should upsize all the radiators which isn't cheap. I agree it is great if you are either building a new house or doing some serious upgrade, but it is really difficult to do it incrementally when money gets available.
@TechConnectify man I wish I could but it’s too damn expensive to buy a house here and it’s really a bummer. :(
@TechConnectify It was pretty easy to switch to all electric here in TLV, most homes already use electricity for everything except cooking (most have detached gas ranges), many homes already have heat pumps as that is the standard HVAC solution here, and water heating is a hybrid solar/electric system (there is a law put in place in the 80s that requires all new homes built to have solar water heating, example in the photo.)
@TechConnectify my flat is all electric, there isn't even gas to the building. Now if only I had something better than storage heaters
@TechConnectify Drying your clothes with GAS HEAT????

@TechConnectify I'm still surprised to see so much of the US homes are heated by gas. I grew up in a place where electricity is really cheap and houses have been full electric for a while. I have literally never seen a gas cooktop in my life except in restaurants. They're really just a luxury, something that only rich people have over here.

Great video though

@TechConnectify Wow! In the uk we pay the equivalent of 40 cents / kwh. 10kw for 15 hours a day would cost us $1800 a month. Gas is about a third of the cost of electricity, so the uk isn't going to switch to electricity any time soon. Alas, the heat pump option requires a big capital outlay. Same problem.

@paulrudman I'm not gonna deny that gas is still cheaper, but just keep in mind it would only cost that much with 30 straight days of not-breaking 0°F/-18°C.

With our rates, that day cost about $30. But the rest of the month averaged closer to $10/day. It was still a frightful power bill for them, and they absolutely should have a heat pump. (edit - did the math wrong)

@TechConnectify @paulrudman This is on point. 10 kW is the maximum. And that's for a large and inefficient American home in cold American winters. The average UK home only has a peak heat loss of between 6-8 kW. So...on the coldest hour of the coldest day of the year the average home still use less than 10kW.

And that's before you consider a heat pump which will use only on average a 1/3 the energy.

@TechConnectify Great video. My house has a 200A service but no insulation 😂 Redoing our attic with cellulose but it’s true, non-framed, brick construction with no furring and plaster on said brick so it’s hyper inefficient. With an electric car, range, dryer, heat pump and a gas water heater / furnace we spent $250 on gas and $210 on electricity last month. And that’s at $1.11/therm and 12c/kWh. 😬
@snazzyq eek! that's... that's a lot.
@TechConnectify Yeah, not great, Bob! Redoing attic insulation should help a bunch (I hope). On the flip side, it’s quite cheap in the summer because the brick stays cool and breathes well into the late PM before we need to go crazy with A/C. Really only run A/C 24/7 a few weeks in August. Except last year 🥵 💀
@snazzyq @TechConnectify we (Massachusetts) just converted from fuel oil in our 1860s house, to air source heat pumps. MA has very expensive electricity, our electric bill this winter was $1,000-$1,300 a month this winter. It’s still cheaper than oil (and now I have heat zones unlike previous steam radiator system).

@JoeRodricks @snazzyq @TechConnectify I remember you. You were running an overnight test with your heating system around Christmas.

I just paid the electric bill where I’m house sitting in the Midwest. The heat rate, on a separate meter, is 0.065 per kWh.

Total bill this month was $280. This bill was low & took work to keep low.

I just looked at the Massachusetts electric rate. If I were you, I’d trench a gas line to the house.

@snazzyq @TechConnectify fam, I wish I had $0.12/kWh. Here, it's $0.20/kWh off peak and $0.40/kWh on peak. A $400 power (gas and electric) bill is considered low.
@snazzyq @TechConnectify I enjoyed it also. I have Span system but sadly it’s my secondary panel because the Ford Home Integration system doesn’t like the span panel (and apparently now my truck, too).
@Aminorjourney that's a bummer! I think Ford's idea there is really cool.
Relatedly, I'll be arranging a longevity test on my Ioniq 5's V2L function soon. I want to see how much of the pack using it to power my fridge, freezer, modem, laptop, and the appliances needed to cook meals for the day (like a portable cooktop, toaster oven, microwave) uses. Very curious to find out!
@TechConnectify given the size, at least 3 days.
@Aminorjourney My math makes it close to a week! But I want to know what the standby losses are, so I'll hook everything up through the kill-a-watt and compare what left to what SOC loss was
@TechConnectify @Aminorjourney I ran mine for a week last May powering a couple fridges, Wi-Fi, some LED lights. Used around 10% of the battery but didn’t cook with it (used a BBQ instead) so was only drawing 200W when the fridge was running. The rest of the stuff was less than 100W so didn’t even register on the car.

@rebelpeasant @TechConnectify Before the (now broken) Ford system was installed, we ran the entire house electrical system (including a couple of resistive heaters and the server room) for a few days just by running extension cables to our truck. Still had 1/2 the power left when done.

@TechConnectify I cannot wit. Also, I’d LOVE a price comparison to alternatives. I suspect mine is the most expensive and useless.
@Aminorjourney @TechConnectify Can't wait for the Enphase V2H system to go with my Enphase solar panels!
@TechConnectify made me check my fuse box: Germany, new semi detached house: 35A x 3 phases x 240V = 25kW. Next size up appears to be 63A.
@timo @TechConnectify the sizes comon in gemany are (25A) 35A (40A) in older homes and 50A, 63A (80A) in newer ones. Mostly 3 phase sometimes 1phase 230/400V
Luckily no HiLeg-Delta

@TechConnectify re:rooftop solar, there's been active work on the policy side for how to fairly compensate for the benefits the resource contributes to the grid. As more solar comes online, the value increasingly depends where exactly the rooftop solar is located so it can substitute for new transmission and distribution infrastructure. This article is a good primer

https://www.greentechmedia.com/articles/read/distributed-energy-value-properly

Distributed Energy Still Isn’t Valued Properly, Report Finds

The result is underpaying on some small-scale projects and overpaying for others, with billions of dollars on the line.

@jasserole Thanks for that!
@TechConnectify I used to work in this space so I'd be happy to help if you could use some more direction

@jasserole Frankly, I don't intend on making content specifically about DER and all that.

But it does irk me that folks I otherwise admire seemingly aren't getting this issue. Rooftop solar is just really hard to manage well, and it's not too surprising to me that some utilities are saying "hold on, we need to figure this out." I think we should figure it out, yeah, but I wouldn't paint it as malice as some do.

@TechConnectify very well done. Looking forward to part deux.
@TechConnectify how did you come up with that order of priority? It seems like you would actually want the heat to be one of the lowest prioritys since it's on for the longest and it only heats while the other things heat and do something else.
@rimpull It's my midwestern "if the heat shuts off the pipes could freeze!" paranoia coming out.
In hindsight, it's absolutely fine to shut it off, especially for cooking since that heat's getting into the building anyway. But you can do whatever you like, really!
@TechConnectify While the SPAN load center are interesting, I was able to get a service upgrade (above ground wiring) for $2200. Way cheaper than a SPAN service panel.

@tebrown @TechConnectify I similarly went from 60A to 200A for $5200 (Bay Area, CA).

Turns out that the cable from the pole to the weather head was already 200A capable and upgraded at some point, but everything else was original 1941 service (going to a subpanel that is modern, so no knob and tube anymore).

The cost was mostly because PG&E made us relocate the panel since its original location in 1941 was under the house in an access hatch.
