Electrify Everything Course Everything BUT HVAC

[@simply-meenal]

We’re happy with the Bosch heat pump dryer.

[@steveschmidt6866]

Great course! We opted for a combined LG washer dryer (condensing) because our panel was very constrained and it only needs a normal 120V outlet. It works great and uses very little energy. It takes a while to dry large loads, but as you noted you can run it overnight, and because it's so simple (no need to move clothes from washer to dryer) we end up doing smaller loads more often.

Soooo cool my friend 🙏🏼🖤

I tried talking to my wife about induction stoves last week, and she was vehemently opposed to even considering one. I even suggested getting a hotplate and trying it out, and she wasn't on board. Do you have any recommendations for successfully selling someone on induction stovetops? Your pollution argument is a compelling one.

[@TedKidd]

That amount of vehement closed-mindedness suggest that she's a laggard on the adopter curve. This means no amount of logic is going to change her mind. Buy an induction hot plate for yourself, and don't force her to use it.

[@sudeepyegnashankaran7583]

Had no idea about fireplaces taking out more heat than they give back!

How much of an efficiency penalty is there for heating water to 140 say vs 120?

[@nateadams8475]

Not exactly sure, but in my understanding it's in the 10-20% range, translating to 100-250 kwh/year extra or $10-$35. You likely spend more at a meal out...

A couple of things from this video: 1. If you are in a cold climate, venting the HP water heater into an unconditional space just means you will be pulling colder air into the building somewhere else. It's more efficient to vent in the house. If you need to put it in a confined space, cut holes and use vent covers to allow air in and out. 2. If you have to use resistance heating for any reason, switch the water heater to resistance to maximize its COP - using 4 kWh to heat the space and 1 kWh to pull that into the water is less efficient than just using the 4 kWh resistance in the water heater. 3. I have a full size Whirlpool HybridCare ventless HP dryer. I believe based on its specs it's a 1300W appliance. Works well enough but does take a while to dry. Needs to be taken apart once or twice a year to clean out so that it operates properly (and I mean fully taken apart - you need to be handy to care for it properly). The nice thing is it works well with my HP water heater - any waste heat from the dryer is used by the water heater since they are right near each other.

The fact that a conventional dryer heats up and vapourizes moisture then blows it outside on a cold winter day is why I am prone to get a heat pump or condensing dryer. Seems like that can be added to the inefficiency. Am I wrong?

Thanks, Nate, for sharing your passion and expertise! Regarding heat pump water heaters: (1) Please remind: What do you recommend for size of HPWH water tank -- smaller vs bigger capacity and relationship to electrical use; (2) Do you recommend a surge suppressor add-on to protect the HPWH compressor motor? (3) Do you recommend installing a better-than-original-equipment air filter on air intake ductwork? Thanks.

[@NatetheHouseWhisperer]

Good questions. 1) I've always found that a 50 gallon tank suffices, I turn the temp up and use a mixing valve. 2) Honestly hadn't thought about it, not a bad idea though. 3) Probably not, the odds of reducing airflow and equipment life are too high, it's warranted with the crummy filter.

[@peterbrown6610]

Does the induction stove still use resistance heat for the oven portion?

[@NatetheHouseWhisperer]

Yes.

[@michaelpolsinelli2345]

There are some now that also have convection and air-frying capabilities.

[@mariongehlker2618]

I see the advantages of induction cooktops/stoves (turns on & off fast, you don't burn yourself etal) but do they actually use less energy than your regular electric cooktop/stove?

[@NatetheHouseWhisperer]

Missed this, yes, about half the energy of electric resistance and less still than gas.

[@elinlic]

Great video! What portion of your customers opt to electrify their other appliances at the same time they are moving to heat pump? Also same question as Marion about induction cooktops. Do they also use less energy or is it just a superior product than regular electric cooktops?

[@NatetheHouseWhisperer]

It depends, but if HVAC and water heat are on the table, it often makes sense to tackle the dryer and stove too while the electrician is there. And yes, induction uses a lot less energy, about half of electric resistance and about 1/4 of gas iirc. Overall it's not that big of a deal though, while they are large power pulls, they don't run that often or long.
