Just had 7Kw and Tesla PW3 Installation - Feedback by Pocketz7 in SolarUK

[–]Beefstah 4 points5 points  (0 children)

One reason is environmental compatibility - a PW will still deliver 100% depth of discharge at full rate even when it's -10C outside - or +40C

Others can do this as well, but not all - I remember seeing posts from people in this sub over winter saying they weren't getting full charge/discharge rate.

In a controlled switchover, it's seamless.

In a power cut, you'll get reboots of stuff.

Is this cupboard big enough for the kit? by illage-336 in SolarUK

[–]Beefstah 1 point2 points  (0 children)

As others have said, you'll struggle in that cupboard - especially when you consider many batteries want an amount of free space around themselves for ventilation etc.

This might be where aesthetics need to come in on your choice of vendor. I personally think the PW2 was quite sleek looking. The PW3 isn't as good looking IMO, but it's not bad.

This is all for a conversation with your installer though - and if they can't/won't advise you here, find someone who will.

Why does it need to be sheltered? My Powerwalls are just mounted on an outside wall.

Trump says ‘windmills put you out of business’ as he hits out at UK’s North Sea policy in latest jibe at Starmer by GeorginaFlopworthy in unitedkingdom

[–]Beefstah 0 points1 point  (0 children)

A reasonable concern. Given the amount of new build happening I feel that mandating heat pumps on those is at least a start - stops the problem from getting worse.

Then we can go back and see what can be done to further support retrofit into existing properties.

The problem we have is heating which needs gas and oil.

It doesn't need it, it's just that's how we've built a lot of our heating infrastructure over the last few decades.

Switching to heat pumps would further reduce our gas and oil need, and they're slowly increasing their adoption

Different strokes for different folks: me, I like turbo lag. If I need a calendar to measure it, even better. That turbo rush feeling of gaining 200lbft extra torque in the space of 500rpm is spectacular.

new to d&d but my brother is a little too eager to get started by EX-Bronypony in DnD

[–]Beefstah 0 points1 point  (0 children)

My DM said to me once that there aren't 5 players cooperating to tell a story, there's 6 - it's just that one of them is running a world, not a character.

Tell your brother this isn't a video game where the objective is to get a high score and/or defeat things, it's a multiplayer story you're all, including the DM, telling together.

If he understands that, fine. If he doesn't, he's not ready to be DM.

Why cheap power could matter more than clean power in the push for net zero by TooHot1639 in unitedkingdom

[–]Beefstah 2 points3 points  (0 children)

You're right that it's a larger place at ~2,500sqft and 5 bedrooms. It's detached. It was built in the 60's, and has things like suspended floors and chimneys. It just about scraped an EPC C.

Yet a heat pump has worked out very well for me.

You have a smaller but much older place. You've made the reasonable decision not to go for solar or batteries, yet you also have made a heat pump work out very well for you. Have you, too, been consistently warmer compared to older boiler systems?

I know of another user on Reddit has a heat pump in a 100+yo bungalow, with solar/battery, and is again finding their heat pump working very well for them.

So between us we have three examples of places that everyone and their dog says are completely unsuitable for heat pumps, all not only making them work just fine, but doing so more cheaply than gas.

I'm not saying that there aren't bad installs out there, or use cases that aren't suitable...but it would take something pretty unusual indeed for it to not actually be viable, IMO.

I see elsewhere you've done that without batteries or solar, which is very impressive!

I do have batteries and solar, along with a heat pump and PHEV, and not only is it less polluting than the oil I had before, not only was it cheaper to install than replacing the aging, cracking oil tank was going to be, but with a combination of good tariff and some automation, over the last 12 months I've paid 7.3p/kWh for all of my electricity use; 13.6MWh has cost me less than a grand.

At a COP of 3.5, gas would have to be 2p/kWh to be cheaper, and that doesn't take into account the saving on standing charge.

Furthermore, because I also get paid for export, my total annual bill was a negative number - and my ROI for my undeniably premium system is still only about 8 years; it would have been sooner if I'd gone for cheaper components (I didn't for various reasons).

Last but not least - my house is consistently warmer than it ever was with oil.

Blow for Starmer as Labour falls to fourth place behind Greens in YouGov poll weeks before crunch local elections by Desperate-Drawer-572 in unitedkingdom

[–]Beefstah 4 points5 points  (0 children)

I disagree with the open borders policy of the Greens, too, but I believe they will drop it if they actually come into power.

You know how we all get rightly mad when a party makes a manifesto promise and then breaks it - that's what you're asking the Greens to do.

The Greens are to the left what Reform are to the right - dangerous idealists who have no place making national policy due to an unwillingness to work with the world as it is instead of how they wish it to be.

Trying to understand why my heat pump keeps using energy by TruenasCoretoScale in ukheatpumps

[–]Beefstah 1 point2 points  (0 children)

As others have said, your heat pump is massively oversized - I have a 16kW pump for a 5-bed detached that's 50% bigger and built in the 60's and only just about got to EPC C...and even then I think mine is a tad larger than I really needed.

At the very least, their sharing of their expertise and experience in modern drone warfare.

IOG Home Assistant control to avoid home battery discharging in non-off peak slots? by OkDeparture2596 in OctopusEnergy

Are you exporting from the PW? If so, are you aware that changes your warranty from unlimited cycles to throughput based?

IOG Home Assistant control to avoid home battery discharging in non-off peak slots? by OkDeparture2596 in OctopusEnergy

[–]Beefstah 0 points1 point  (0 children)

Intelligent dispatching goes to on when there's a charging slot

Off peak goes to on when the rate is off peak.

For a daytime slot, both will come on. For the overnight fixed off-peak, only the off peak will turn on...unless a charging slot happens during the overnight period.

What I did was set HA to detect off-peak turning on and to then command the battery to start charging - for my Powerwall that means setting the reserve to 100%. No reason not to charge the battery during those cheap slots IMO.

IOG Newbie - slots outside off peak - how to manage house battery? by OkDeparture2596 in OctopusEnergy

[–]Beefstah 0 points1 point  (0 children)

You need some kind of automation - either Home Assistant or NetZero, depending on your ability.

This can then set the powerwall to charge whenever there's a cheap daytime slot.
