THE FUTURE OF HOME ENERGY is HERE - A GAME CHANGER FOR ELECTRICIANS
Переглядів 65,144
2 роки томуWhile world leaders gather at the COP26 conference to talk about decarbonising, a small housing development in Wales is already ahead of the curve. This development of 25 homes by Pobl includes all of the key low carbon technologies. Solar panels, ground source heating, Mixergy intelligent hot water cylinder and the three-phase EV charger.
The clever bit is how the Sero Group has integrated all these technologies to work together seamlessly. The result is an ultra-low energy home that is easy to use.

That's a show house? Really? The installation looks like it was cobbled together by a hobbyist, the fit and finish on the plaster is horrible, the paintjob got anywhere it shouldn't go, the installed controllers look like they were designed early last century (been ages since I've seen a digital room temperature controller that doesn't have a display and half-degree steps from 12 to 30°), the location for the battery is just a joke and its extending frame (seriously, it looks like it was designed to be mounted flush INTO a wall) is a major injury risk (perfect height to put holes into kids' heads on the lower corner there, too), that cable at 9:22 that's fixed at both ends but flapping in the breeze would be a major code violation here---that's dangerous, one little pull and you'll ripp a potentially live wire out of the wall. Especially in an area where you need to grouch because it's not high enough to stand and could easily grab wildly to stop falling...

It's ridiculous to see a 2-bedroom house cramped with so much technology that takes a lot of space. That big battery cabinet hanging off the wall in the kitchen is like a soar-eye, not to mention how much exposure to damages that is (hitting the unit with the kitchen door. And is that even a proper place for a battery unit to be in, a heated environment? Why not a garage or any other cool areas, a non-heated hallway? I also agree with those electricians that pointed to the cramped cupboards where you have all the distribution boards, meters and not enough space to work safely. I don't think German houses are built like that. They have 3-phase Distribution Boards, nicely done, placed in a well ventilated area with full access to them. They put great thought in designing smart homes, sorry UK!!! But I think the future houses would be at more potential fire hazard and safety risk with all these technologies cramped in and not enough space considered for such things.

@montystelevision3238 2 роки тому
I wouldn’t want all that gubbins in my house. I saw a newspaper article where a family ripped out a heat pump and shove it in a skip and installed a normal boiler due to the heat pump breaking down and not delivering enough heat and power. So that’s already one heat pump down the tip.
@paul756uk2 2 роки тому
Heat pumps are ok in high spec and one off builds where insulation levels are much higher than spec built houses. Also underfloor heating is an absolute must because of the lower temperatures required. Heating radiators and hot water with a heat pump is sometimes unachievable in cold weather. Just another example of imbecilic government ineptitude to bow down to the climate zealots and consign everyone to poverty.
@tlangdon12 2 роки тому
@@paul756uk2 There's no doubt that using a Heat Pump to heat domestic hot water is inefficient. It is generally much more cost effective to use the heat pump during the middle of the day (and overnight if you have a ground source for the heat) to collect water for heating, and to use the solar panels to run an immersion heater to heat the domestic hot water to a higher temperature. In theory, you can use one thermal store to store this water at two different temperatures, but I'd like to see research into using a direct cylinder for the domestic hot water, and a thermal store for the heating.

That’s very encouraging and should be mandated for all new builds. However, I think that developer must have decided on the GSHP and the associated kit late in the design phase as it has been shoehorned and cobbled together in a number of spaces that are not entirely suitable. If designing with a blank sheet of pump you would want all of this kit in one plant room (including the hot water cylinder).

Absolutely no developer under the sun will even consider such stuff unless forced and the inevitable poor installation and fabric quality will lead to very unhappy homeowners. We still have boilers being installed that pass building regs and SAP that aren't even designed to run at condensing temperature needed for efficiency... What hope do we have for correctly designed and installed ASHP? You'd be better off building a commercial size demand shifting storage battery for the whole estate underground or somewhere amicable rather then splitting it up between every house. At least then it could be properly regulated and has a chance of being done properly and buys you the time until the grid goes net zero.

@@acelectricalsecurity but that's the thing, everybody *won't* be charging their cars simultaneously. Very few people will drain their ev battery every day and when they do need to charge they might plug in when they get home but the charge will be timed, either by the car or by the system, for a few hours on cheap rate if they charge from the grid. Most people commute about 25-30 miles a day so even the least efficient ev will go three or four days without the need to charge, many will only charge weekly or even monthly. Not to mention the fact that more and more ev's have V2L. Charging whilst at work, charging whilst at the supermarket, sip charging I think they call it. So this simultaneous charging draining the grid is a total myth. As for the three phase, not my remit but I think it's something to do with keeping the high consumption devices separate from the rest of the everyday usage... I'm well aware of my limited knowledge on that though. I do know that the point of pv and battery storage is to relieve pressure on the grid at peak times. The system, being smart, decides when to switch to battery and when the grid can cope, I believe, its not expected to power the house twenty-four seven. However I'm sure if you take a look at the Fully Charged episode on this (sorry, no idea how to provide a link!) you'll see that the development is almost self sufficient. Not sure if I've imagined it but there might even be separate battery storage on sight, hence my idea that it was off grid. Disclaimer : I do have ME/CFS and the brain fog and lack of memory do rather cause problems with accuracy. Just on the really technical stuff on which I'm less educated though so I hope the rest of my points are valid.

The underlying system for control uses erlang at its core, the same language used in telecom systems, its designed to be remote debugged, can self heal, and like telecom systems is designed to maintain uptime... every device connected to the system sends a heart beat that alerts of any issues, and if a part is showing issues the system can restart that single piece of control code automatically. The config can also be upgraded over time with new device drivers using all the standard communication protocols for wired and Wifi over the air via a separate 4g modem so is not reliant on users wifi. It's been designed to avoid the need for callouts as much as humanly possible. The system was designed with minimum maintenance in mind, and can be debugged remotely. So beyond actual hardware failure the software was designed to be as flexible as possible. The system uses secure tokens that are rotated, and has security considerations at its heart to connect to googles cloud infrastructure. We also set schedules on the devices themselves so even when there is no cloud communication the devices will continue to function, the system can also restart itself to the last good known state automatically if issues arise. All the devices installed also can use their standard communication protocols so they can be controlled via their own native apps if required. So the technology is designed to be robust, secure, self healing, updatable, configurable and resilient and far as is possible.

@markellse 2 роки тому
It's horrifying to think how much all this stuff will cost. The 5 kWh battery store will be more than £2500. If you want it to last for 1000 cycles you mustn't charge it above 80%, nor discharge it below 30%, so it will really only store 2.5 kWh. Over its 1000 cycles that will store 2500 kWh. So that battery will add, IN STORAGE COSTS ALONE, £1 to every unit of electricity it handles. This is complete madness. As for the ground source heat pump, that 3 kW heat pump that you use to pull heat out and the extra costs of a low-temperature system cost in the order of £7500. If it lasts for 20 years, and it won't, that's £375 a year or about £1 day. If the system is on full power in winter and zero power in summer, its average power is 1.5 kW, ie 36 kWh per day. So that's 3p per kWh capital cost on top of the running cost of the system. In fact, the system won't last as long as that and in will need expensive maintenance. Call it 6p/unit capital cost. The heat pump will have a maximum coefficient of performance of around 3.5 (less when it is producing high temperature heat for the hot water cylinder). That means that it generates 3.5 kWh for every 1 kWh electricity supplied to it. At current electricity prices of around 20p/kWh, that means it produces 3.5 kWh for 20 p worth of electricity, ie about 6 p per unit. Add to that the capital cost of the heat pump heating system and you at around 12p/kWh. In fact you won't get a COP of 3.5 because the heat source will gradually get colder during the winter as you pump heat out, making it harder to pull more heat out, hence reduced efficiency. That will have have two consequences. The first is that you will need more energy from the supply to pump energy from the source, the second is that you will have to use on-peak electricity to make up the difference...and on those cold winter evenings, when there is no solar and there is high pressure over the whole country so the windmills are not working, your 5 kWh of battery storage (only charged to 4 kWh remember because you want it to last for 1000 cycles) will supply your heating needs for less than 2 hours, even if you run it dry. You will have to resort to the grid, which will be burning any fossil fuel it has, at an efficiency of 33% when you take into account distribution losses, so you will want the grid suppliers to burn 12 kWh every hour (that's 12 kW) to supply your measly 3 kW heating load. I'm sure that there will be mistakes in this analysis thrown together. Do correct me where they exist. And forgive me for my realism. By the way, just a couple of unit slips in your normally excellent dialogue. 5 minutes you say a storage of 10 kW. That should, of course, be 10 kWh and just after 8 minutes you refer to charging a car at 22 kW per hour. That should be simply 22 kW or, if you prefer, 22 kWh per hour.

In fact you won't get 360,000 miles if you charge it fully and drive it 360 miles every day because the capacity of a battery reduces rapidly when charged and discharged fully.

@steveb1739 2 роки тому
@@efixx Hello Mr. eFIXX. For starters, simple high-school physics. If you burn gas in a domestic boiler, it is cheap and efficient. Running a heat pump (inter alia) is not. So, you take gas, and run a gas turbine to generate electricity. Then you step up the voltage to transmission levels. You transmit it. You step down (in several steps) to LV levels. You then run your heat pump. At every step, there are considerable losses. So best just take that gas and burn it in your boiler. You might argue renewables. Well, they are not reliable. Great whilst the wind is blowing, or the sun is shining, but that does not happen constantly. The only way would be nuclear, but those plants do not get built over a weekend. Plus the (misplaced in my view) public resistance to nuclear. Never mind the French have relied on it for decades without too many issues. Same story with motor vehicles. Rather just fill them with petrol or diesel, treat the exhaust, and just get going. Let's not get into the whole global warming / CO2 bunkum, but remember every living entity from a Corona virus to a Blue Whale is carbon based. As for physical CO2 emissions, has anyone ever calculated how much CO2 a living human exhales in a day and decided to action that? I didn't think so... Every autotrophic and photosynthetic organism requires CO2 to function. Optimal levels on earth would be around 800ppm. We are at around half of that. Reduce CO2 any more, and we will see massive desertification, and rain forest destruction that will make logging / jungle clearing look like a child's picnic. Whilst I am absolutely in favour of mankind cleaning up its act, take the money out of this "Green" nonsense, and it will disappear as the darkness disappears at dawn. As I have said before, make these new technologies cheaper, and more efficient to run (forget about the initial capital cost), and there will be an immediate and unreserved uptake.

@@efixx single phase control circuit with 3 phase contactor? Then you don’t need an ugly 45A DP switch either.

3 phase No mention that I heard about what size solar array was fitted to take advantage of feed in . Again with the battery what size how is it being utilised what is the overall controlling strategy . Ground source heat pump nice but why go to radiators in the bedrooms when these could be underfloor. This is a new build ? This idea of new build estate with no gas. All high tech ? Fine. But why not go for a district heat system that provides hot and cold water to each of the houses. To run under floor heating and or fan coil type units providing both heat and cooling in the property. And meter this heat / cooling energy and bill for it. Then the local common heating / cooling source can be built to a larger scale and more efficacy . Then all these small package units. More redundancy and maintained by external company . And why no rain harvesting ? To reduce the demand for expensive treated water .

How much is a ground source heat pump, the electronics and the central heating system. I’ve heard you may need two bores to keep a larger house, 4 bed, at £20,000. Not a cheap system and not very green considering the amount of new electronics.

The key is to make sure your property is well insulated first - that reduces install costs and running costs. The houses in this project have a shared bore hole (170 metres)

I have an older property, which I have insulated below the timber floors it also has external insulated render. My house although insulated to a high degree would not benefit from this type of heating. The problem with older properties is they’re draughty, manly from the lath and plaster. In order to get an older house up to the specification, insulation and draught proof, wold be to rip out and start again. This is not practical nor financially viable. This system works well in a modern build well insulated and sealed house and not for the majority of properties in the UK.

By the time this video was published the "being paid to top up your battery from excess green electricity" boat had already sailed - and it seems unlikely to return. The Octopusagile tariff, which had dropped prices below zero on occasion, has barely dropped below 25p per unit for days (or weeks), and were it not for the max price per unit at present being 35p, it would spend a lot of the time above that, instead of being maxxed out at 35p as it is presently. The cost of EV charging is under pressure to rise too, as more vehicles come online, and the overnight consumption of electricity rises as a consequence. When the price cap is raised (in April, I believe) I suspect that both on peak and off peak tariffs will see significant increases. So, unfortunately the batteries and smart appliances those home are equipped with are soon going to become much less of a useful feature. It's not unlikely that within a few years electricity will be charged at two rates, with vastly different times to the present day: low rate from say 20:00in the evening until 16:00 the next afternoon, and then peak rate from 16:00 to 20:00 daily.
