  • In my view Joe this is the best summary I have ever seen of the future of electricity as a energy source to heat our homes. The recent increase in the gas prices of 75% per kwh and 33% for electricity shows a competitive move away from gas for the first time in decades. Please take a look at my all electric heating video. I have had an all electric system for more than 25 years. My bill for the next 12 months including 33% increase in April 2022: £1950. About the UK average dual fuel bill for a typical 3 bed semi. And I enjoy whole house 19-21c warmth and no repair bills. And if you take a look at the figures at the end of the video, there is the proof. Can anyone show me performance figures, not just cost, for a gas central heating system?

  • Fine in principle, but even at maximum efficiency, electric heating is way too expensive to run unless electricity prices fall by a huge amount. I'm in the country, gas is not an option, my only realistic method ( it's an old house with wet central heating) is oil, which I hate. Looked at GSHP as well, but they can't deliver water at high enough temperature. Stuck with oil for now...

    @phildxyz@phildxyz3 жыл бұрын
    • Why not just combine GSHP with a tank and element for the last bit of heating up to the usual hot water temperature? Yes the resistive element isn't as efficient as the heat pump but the heavy lifting would've already been done so it would have less heating to do. Meanwhile the GSHP can be heating your house as well. Or if you don't have a bath in the house, instantaneous (or small tanked) water heaters are fine for sinks, and then a normal electric shower.

  • I put in an electric system in 2016 and it is horrendous. Noisy (gushing water runs through system), costs absolute fortune to run (on economy tariff), needs two meters, therefore, no smart meter possible, thermostat is useless and always needs manually boosted, ugly copper pipes everywhere, roof fell in as seals perished after 2 years, do not hold heat, I could go on. To me, electric heating has always been useless and expensive to run. I need convincing! Because something is labelled as eco does not necessarily make it good! I am £160 per month for small, modern 2-bed flat. No gas. My bills nearly tripled when I put in the new “economy” heating on my “economy” tariff! Still trying to figure out where the economy comes in!

  • We're going to get electric radiators which can be controlled by an app on a smart phone. I'll also be able to monitor how much electricity were generating from our PV, so can switch the heaters on remotely if it's a cold sunny day in the shoulder season, say mid/late afternoon, instead of drawing from the grid once the sun has set. It'll be interesting to see if we can use enough of our free electricity in the shoulder season, and selling excess in the summer, to offset the cost of grid electricity during the winter months. Should say that it's a new build very well insulated home, EPC 92, wall u value of 0.13. I'm not sure I would want to rely on them in an older home.

Which with my dodgy maths is double. We were already paying close to £3k annually on the old rate with electric heating (storage heaters) in our 1990 built 2 bed semi which were never any good. Luckily we bit the bullet and had a gas supply installed and gas central heating last Autumn. Wish I had done it years ago. 👍

How much would electricity suppliers charge occupiers in the future when the whole property will be powered by electricity? Also how much is the UK actually going to grow the renewable energy industry for all this to happen? We're quite far behind a good amount of countries in this area.

  • Infrared ( far or middle) room heating is available now and is more cost effective than convection electric. The new generation of these look to be a better choice than oil filled convection radiators. Partly because convection is less efficient at warming a room than widespread radiation. Radiation warms all the objects in the room, which then retain and radiate that heat themselves. So it is also less affected by drafts, opening doors etc than convection heaters which rely on warm air circulation. Also because the heating units are flat and thin and can be made of glass or aluminium and hung from walls or ceilings. With gas at 0.03p per unit and electricity around 15p unit during daytime, people are not going to switch to electrical heating unless there is no other choice. However, electrical systems can now be powered by stored energy which is acquired overnight from a renewable energy surplus. When the new offshore wind farms now being built are complete, the surplus overnight energy can be sold at low cost, typically 5p unit, and stored in house or in Electric Vehicle to heat your house at a similar cost to gas.

  • I'm late to the party as I just stumbled on your channel from the other side of the pond. Interesting Europe energy efficiency standards are focused on electrical resistive heating. By its nature resistive heating is 100% efficient from a consumer perspective. Electronic controls will improve set point accuracy, but I wonder what the increase in overall efficiency will be. My guess is pretty minor. Here in the US heat pumps are the rage, basically a reversible air conditioner. Modern refrigerants are able to extract usable heat down to amazing low temperatures providing over unity efficiency compared to resistive heating since the heat pump is simply moving heat not creating it. This compensates for electrical grid losses compared to burning fuel locally.

  • Fascinating! I'm curious if this smart tech can combine w/ "old school" methods underneath housing; Such as Bricks laid out as a "Heatsink", to retain heat & pass+warm air through. I believe the combination of the 2 would be Highly efficient & effective w/ a little added insulation? Especially during the colder hours & months. Adding some fancy "zig-zagging" in the stone & various other tweaks can be made if using something like concrete, or a better type of stone can be used if produced before-hand in a factory setting. 🤔Thanks for posting.🙏

    • If this is the case, it could be as simple as using some "crawl space" and building a relatively small "underground" box beneath housing; In the dirt, for Natural insulative properties, would also have to make sure it's accessible from the top (or side I guess) for maintenance. Then running metal through sections of the brick & applying a current to heat them, along with timers, sensors, fans to move the heat, etc. IIRC: Metal heats up when current runs through it & doesn't waste much electricity if circulated. Not my field, just ideas.🤷‍♂️

      @Rinnittle@Rinnittle3 жыл бұрын
    • Thinking of, this could easily double for and/or help keep hot water warm too, if the usual tank & tech is built on top. Heat both conducts & travels upward so, as the box below warms, it'd naturally share off 1 "source." Oh, depending on the square footage of the house, or a configurable setting by the user, the smart tech can get the stone to optimal temperatures. There's several ways to go about controlling things with a little added tech. For example: Getting the stone Hotter may retain heat longer, but then comes the issue of the vents possibly putting out heat which scalds. I believe this could be remedied with 2 fans, instead of 1. By using 1 fan to move & "buffer" the air, another sensor & fan could then mix cooler air from under the house with the flow going to the interior, thus decreasing it & adding "control." Or by positioning a single fan in the proper position, it would naturally pull cool air from under the house but also from inside the "box" simultaneously, which would eliminate the need for 2 filters. Also, for safety, multiple sensors acting as "backups" & basic alerts on the owners Displays can prevent failure & misfortunes of encountering mentioned "scalding air." Couple other ways you could go about all this, such as using shutters or passing it through/around the hot water heater; Which could save some duct (piping) and/or allow for larger hot water capacities. 🤷‍♂️ Many options.

Meanwhile gas was contributing 52% It makes no sense to turn gas into electricity, and then use that for heating when you can use that gas directly for heating. Making gas into electricity, then using it for heating will just overload the grid, and is a completely ridiculous at the current time. Resistive heating is 100% efficient and always has been.

    • So true. It also will need every street of every town to be rewired probably to 30kW 3 phase and many times that on main roads. Why? Because as well as the unpredictable switched loads from the heaters described here EV charging will change to require huge electrical sources for superfast home charging. Then there will be a new need for two source energy for backup. Now that could be electrical so we'll need to dig up the roads again. Then we might all press for more solar panels but these cannot be turned off by the generator companies in order to maintain frequency and voltage. That's no problem at the moment but it soon could be.

But, don't forget the maintenance costs of servicing a boiler, then the cost of replacing the parts of the boiler or the boiler itself after 10 / 15 years. A well installed electrical installation should last 30 / 40 years. Not sure how long these radiators will last but I think the cost overall will be less long term. And also you don't have pipes underfloor boards that could spring a leak!

    • @@efixx Sadly, renewable doesn't mean cheaper and it probably never will. In my view, the only way electricity can be used efficiently for heating is with underfloor heating using an air or preferably ground source heat pump and even then that's with new installations. The gas fields where we currently get our gas from are good for 100 years so i think gas will still be with us for the foreseeable future despite the government making noises about banning gas boilers. I also think going down the hydrogen path will be nothing more than a fad. Obviously we should be developing new sources of energy that relies less on fossil fuels and that doesn't necessarily mean renewable energy. As a comparison, I'll be shortly paying around 14 pence per kwh (up from 11 at the moment) for electricity and around 3 pence per kwh for gas.

  • The future will be in heat pumps, as that is an electrically powered solution that provides 300% efficiency on average today. Any form of resistive heating is only 100% efficient - so go ahead and buy a cheap unit if you take that route. As a plus, a heat pump run backwards is an air conditioner - something more UK homes will likely want going forward.

    • Heat pumps are very common here in the U.S., especially here in the south. I'm in Central Florida and last month I used 745 kWh to cool a roughly 111 square meter home in 33 dgree weather. This place is relatively new so it's got decent insulation and I live alone, but everything is electric. (If you are wondering what I am doing here, I found the channel last week while researching ferrule installation,)

    • Can you use the correct term, coefficient of performance, and not efficiency when referring to heat pumps? It should also be recognised that the quoted values of COP are invariably achieved under ideal lab conditions. An air source heat pump in a cold damp British winter is going consume energy just to keep the evaporator free of ice.

  • Written by the American grid lobbyists looking to sell in Europe. - electric heating cost a fortune to run 1 for 1 ratio an average og 600 a month, hence the promotion of heat pumps which reduces to a 3rd in ideal conditions . Sustained heat are a broken idea especially when pricing to run outstrip most people’s budgets, let alone pension weekly budget for the retirees, the grid are determined to introduce peak rate super charging or 3 their to replace economy 7 or 10 as they stand . Both the infostructures and grid are not ready let alone the public If we are not careful one bad winter and we’re end up like Texas, there’s a big difference between heating your electric shower and heating a home , you’ve only got to look at the demise of the traditional 2 bar electric heaters to see this idea of heating electricity is just impractical to expensive for the majority of U.K. housing

  • I understand the desire to get away from fossil fuels, however renewables are never going to be providing 100% of the grid. So you have to look at nuclear for the base load, and the next cleanest fossil fuel, which is gas (of which the UK has an abundant supply). Where this is just silly, is using gas to make electricity (eg CCGT at 60% efficiency), transforming it, supplying it into domestic properties, to then create heat. When a domestic property can take the gas in directly, and burn it at >85% efficiency for heating. A heat pump will help with the efficiency, but still nowhere near the efficiency of burning the gas directly.

    • I think there is something wrong with your maths; modern heat pumps can easily achieve 300% efficiency, actually the best ones are now 400-500% So for a heat pump it's 3 x 0.6 = 1.8 i.e 180% worst case end-to-end efficiency, which is at least twice better than the paltry 85-90% achieved by a gas boiler. The direct electric heater at 0.6 x 1 is only a little worse, and since gas now accounts for less than 50% of UK generation it's still better than a boiler in terms of emissions. SAP 10 recognizes end-to-end efficiency and carbon intensity of different sources, so gas will effectively be ruled out by it's introduction. Clever, no boiler ban needed.

  • Let me burst the bubble....golden age for electricians....we will see there is also disruptive technology on the horizon that could help it go the other way such as the use of POwer over Ethernet (Poe) devices and a large move over to low voltage light, switches even heating and cooling devices as efficiencies resulting in much greater smart integration. None of it would require the kind of electrical expertise needed to work on mains voltages (not that it stops DIYers) However my bet is that electricians are going to need to be even better trained and able to look at network hardware, software issues and cyber security aspects to protect and safeguard all these smart devices. More than that testing will need to cover in much greater detail power quality issues not just safety testing with the growth of semiconductor devices, mix of Dc power and AC mixing. There are opportunities but also disruption will older sparkys be keen to learn.... will younger sparkys be able to learn at higher more academic and trained levels for longer possibly incurring more debt before they can make money that will be the true test. If they do yes the opportunities would be great and hopefully better pay for electricians.

"Now is not the time" - I disagree, now is the absolute best time to be doing this, as the need to get rid of GHG-creating gas and oil is only going to get stronger over time, and the later we leave the transition, the faster, more abrupt and more difficult the transition will be.
