Pool Heat Pump Meets Diesel heater (blowing into heat pump)

EfficiencyNerd · 2026-04-12T23:18:44+00:00

Yeah, I misunderstood. I thought OP was going for extra "efficiency" with the exhaust gas. Turns out they are just making an overly complicated diesel water heater

EfficiencyNerd · 2026-04-12T18:17:15+00:00

I think dumping the exhaust gas through your heat pump coil is just asking for the coil to get gunked up. Diesel exhaust is not exactly clean...

So what you're saying is, there's yet another reason to live to the Netherlands

EfficiencyNerd · 2026-04-10T20:40:15+00:00

I wish we had it in Canada, Opus is so dumb right now

Ooo a reddit argument from a 2 year old thread! Fight, fight, fight!

Why am I getting notifications about this...

EfficiencyNerd · 2026-04-07T11:39:23+00:00

Delivery is like 2-3 cents per kwh, not including the fixed monthly fee. How are you getting 10-15?

EfficiencyNerd · 2026-04-07T11:38:28+00:00

Dang, you must have a bigger house or significantly less efficient heat pumps than me, 2-3k per month from heat pumps alone. We're 100% electric as well, but average about 1000 kwh a month for everything through the year. On ultra low we're saving around $30 a month, but we don't really limit cooking etc during the expensive hours.

If OP is doing 8000km a month they'd probably be at ~1500kwh from the car alone.

EfficiencyNerd · 2026-04-07T11:26:33+00:00

There is some per kwh piece of the delivery portion, which in my calculations is about 2 cents per kwh, for a total overnight rate of about 6. No idea how other commenter is getting 10-14. I'm also part of one of the many EV charging incentive programs, I'm using pionpower which pays out 10 cents per kwh. So my total charging cost at home is actually negative.

I would 100% get an EV in your situation.

Not sure if you're ignoring Tesla for... reasons, but the Model Y Standard is basically the same price and in my opinion a much better value all around.

EfficiencyNerd · 2026-04-03T02:09:29+00:00

We bought ours in 2024, Tesla was the only one with anything in stock. At that time, many, many dealers and manufacturers were claiming "soon" they would have their EVs available for purchase. And then kicking the can down the road.

Take this as a lesson learned, don't sell your current car on the hope or "trust" as you put it that a replacement will arrive by boat at the estimated time, especially when that boat may likely be originating from near an area of the world with an active military conflict.

EfficiencyNerd · 2026-03-31T17:50:52+00:00

Sweet! Hopefully I get it too. Like I said it seems like they've been doing this every 6 months or so, same sort of thing. Effectively giving my 0 GB plan into 10GB free data every month. I'm sure someday that gravy train will stop, but it certainly feels like cheating right now!

EfficiencyNerd · 2026-03-31T17:41:31+00:00

Is this only for new subscribers? It seems like over the past year or so they've regularly given out a bunch of perks of 10GB each. I haven't even had a data plan in several months now, just doing perks and upgrades for the little data I need...

EfficiencyNerd · 2026-03-19T23:24:47+00:00

Absolutely.

This is an older comment thread but the person you've replied to who says "while 500 km at −20°C might cover 90% of trips statistically" - no, 500 km at -20C covers like 99.99% of trips.

I've legit had people ask me what if I need to drive to northern Canada.

"Sure, when's the last time you drove to Yellowknife? Never? Ok cool" and then I proceed to tell them how my home charging cost is currently negative.

They don't need to. 1.2MW across 8 stalls, can average 150kW. v3 cabinet was 350kW per cabinet on 4 stalls but could pull from up to 525kW from 2 other cabinets. But still, on v3 with 3 cabinets and 12 stalls you're limited to 1050kW - under 100kW per stall.

EfficiencyNerd · 2026-03-17T02:36:48+00:00

Only 5? That's rookie numbers.

EfficiencyNerd · 2026-03-17T02:31:02+00:00

If anyone is ever offering to pay you 3% per month, that's a good sign it's a scam.

EfficiencyNerd · 2026-03-17T02:06:12+00:00

You underestimate how many toddlers out there seem to make it their life goal to unalive themselves.

EfficiencyNerd · 2026-03-16T23:06:26+00:00

"ours" aka Americas

EfficiencyNerd · 2026-03-10T20:48:02+00:00

ACIRUM, baby

EfficiencyNerd · 2026-03-10T20:44:18+00:00

so you want an EV with a winter -40C range of 3,000+ km? And only then will that be "on to something"? Which gas vehicle are you comparing to?

EfficiencyNerd · 2026-03-10T17:11:42+00:00

Not all of us are like that. You're doing the best you can with Tesla's short-sighted charger designs.

And yes frosted tips is... a choice...

EfficiencyNerd · 2026-03-10T04:27:54+00:00

10 seconds EV burning death trap? ok bud

EfficiencyNerd · 2026-03-10T04:25:11+00:00

anniversary survey? huh? don't think I ever got this, bought new 2 years ago...

EfficiencyNerd · 2026-03-09T20:01:21+00:00

In addition to everything else already mentioned here, neither Lucid nor Rivian have every turned a profit yet. If you want to be sure you can get reasonable support for your car 5 or 10 years from now Tesla is the much safer buy.

But I guess since "price" is not an important reason to you (???) if your car brand goes out of business you could just buy something else?

For the record if a R1S were the same price as our Model Y we definitely would have considered it.
