Phantom Energy - is a phenomenon which is beginning to be talked about more and more but it’s not all that well known or maybe understood.All electrical appliances generally use power if they are left plugged in, even if they are not switched on. The TV is off via the remote but it’s actually on standby, ready for your next command so what power is used while it does this?Many other devices which respond to a button push are also on standby .. it is the typical way of designing modern devices to have a quick wake up routine. Even low voltage devices operated via a power supply from the mains, use electricity when they are off. The transformer in these devices is connected even when the item is switched off. But what does this mean and how can we do something about it?If you have a smart meter and an in home display (IHD), you will be able to see what power is being used via the ‘Usage Now’ screen so last thing when you think everything is off it will show what power is being used at th
Thermal survey or use an infrared (IR) camera? - what's the best way to see how to improve insulation and reduce heat loss?
I've been considering getting a company to do a thermal survey of our house, to see where we could improve insulation and reduce heat loss. But having seen the photos that @hambrook took with his IR camera I'm wondering if it might be better to buy one and do it myself.Has anyone had a thermal survey done? Was it worth the money? Does anyone else have an IR camera and have used it to improve their home? Are there any other views on which is best?
I have seen that a number of users have storage batteries installed. Given that winter often brings minimal charging via solar PV and most batteries have a cut off level (Li-ion around 10%) how do you manage your system over the winter months?I began by raising the lower threshold above 10% but have recently been charging overnight about once every week but we’re still trying to understand the best way to make use of and maintain it all.
Just wondered how everyone who has signed up to the PowerMove trial is getting on?Just had our mid month statement and we are at 24% electricity usuage during the times of 4-7pm. Clearly some way off the 12.5% target. We have moved dishwasher, tumble dryer and washing machine usage outside of these times (bar a couple of lapses!). Still need to eat during these times so suspect the air fryer is pulling us in the wrong direction! How are others getting on??
I have MELCloud linked to my Mitubishi Ecodan air source heat pump.Recently I lost the internet connection and cannot establish a reconnection.My connection is via Access mode as my router does not have a WPS button.I am able to complete the process for reconnection correctly but it does not connect.I have previously been successful and there are no changes to my home network settings.I am wondering if;the MELCoud server is down?or if I have a non standard password to my home wifi network - it includes a ’ and has a space in it?Any help with reconnecting to the internet would be useful.
I put together a guide to a few of the 3rd party data feeds which are now accessible with a smart meter to view your energy use.I also have been looking at a few other things to explore a little more as, has been pointed out in the Power Move trial, it is mainly with more information that users can make more informed choices.One thing on the Bright energy app is a comparison chart which allows you to see power use during the day. It also allows you to look deeper across days of the week and for the same day over a number of weeks Bright Energy app comparison viewOne thing which isn’t very well explained but shown in the 2 images above is that you can zoom into the image to see the time frame required in more detail. This is simply done by ‘pinching’ the image as often used on smartphones these days.Now that ivie bud is working more consistently alongside the ivie app, you can get an instantaneous electricity use reading together with low and high readings for the day. ivie app feed via
It’s interested what you find when you look .. as well as the Loop initiative, I now see that Hugo are also participating in the National Grid event. Hugo offer a similar service to Loop, remotely gathering data from your smart meter but here you can add your own tariff rather than having to use a default as Loop use. You can only take part in one of these schemes.
Hi all,We built a house and it was finished in 2019. Its to the latest build spec regards to insulation and the likes. Its over 3 levels, ground, first and second floors. Its 5 bedroom, two main baths, a downstairs WC and one en-suite. Downstairs the layout is a kitchen diner, utility with downstairs WC, living room and office. The two bedrooms and one bathroom on the top floor have their radiators all on frost stat upstairs so never come on. The first floor has radiators and 1 thermostat for the entire floor. Its set at 17C in the height of winter and I put it in the bathroom - which the temperature barely can reach. This floor is fully carpeted except the bathrooms which are Amtico vinyl. The ground floor is all UFH, with Amtico vinyl flooring. Each room with a Heatmiser thermostat. Last year (2021) was a mild year. I had the thermostats in the rooms we use (dining/kitchen the living room and the utility set at 18C. The hallway was set at 15C so was the office as we dont us
Hello everyone,I’ve had a new Mitsubishi Ecodan air source heat pump installed very recently.I’ve been looking through the MELCloud app and noticed that if I run the Energy Usage report its not showing any charts - just blank where the charts should be.I’m a software dev, and was able to look at the request it’s making to get the data and I can see that the response has zero/null values for everything - so it appears that the data is not there as opposed to some bug in the app.Is this normal for a new install - maybe it has to run for a while before collecting energy data, or does it perhaps indicate something not working on the ASHP?Many thanks for any help,
I am considering buying a house which has an ashp half installed. a huge amount of work/insulation has been done but not completed. The 3-layer radiators have been bought but not fitted. My question is whether the existing 15mm diameter pipework will be adequate? I read somewhere today that ideally it should be 22mm diameter or more.

There are a number of third party data sets now available gathering info from smart meters so I thought I’d give a few a go to see what they offer. As has been mentioned, the OVO info screens are useful but could be enhanced but what about the others. Loop HomesLoop - a useful and quick series of data which are updated during each day keeping track quite efficiently. This offers not much more than that apart from a solar PV and battery storage simulator but always a go-to for quick info. For some reason, gas always lags electricity by half a day or so. Loop are also running a peak hours reduction trial at present (2022-2023) (example screens)Loop does also have a solar PV and battery storage simulator which can give an idea of possible energy savings with these technologies. You can switch these on and off and also view a calculated kWh saving - however, if you already have solar panels or batteries you will get a false picture as the app doesn’t currently allow you to indicate this
I'm fairly hands on and i want to change the settings in my flow temp controller for my Mitisbushi ecodan PUHZ-HW140VHA2 unit for my 3000 square foot reasonably energy efficient bungalow, it's all underfloor heating. It also has a stove back boiler which helps heats the 300l buffer tank for heating.installer company went bust years ago and im struggling to get anyone that knows what they are talking about. I'm trying to make it run more efficiently so. I had the ASHP installed in 2014. This july i changed a few settings and i think it has been running more efficiently. (my electricity usage would agree with me however it's hard to properly compare in 5 months.It recently it has been giving me a P8 error(See error table below.) i just reset the error and then it goes off about a week later. Maybe something to do with temperature of return water or something. See questions 1 and 2 below as they explain what settings i changed. 1) i switched off freeze protection as it seemed overkill. D
Here’s everything you need to know about what happens to your charger, the V2G app, and more once your trial ends. It’s been a fantastic few years for our V2G trial and we’ve learned so much about both the technology and the part it'll play in the future of energy.If you’ve been involved in the trial, we want to say a big thank you – we couldn’t have done it without you! And, remember, the charger is yours to keep once the trial ends. After all, you’ve helped both us and the world of V2G tech a whole lot! Since it’s yours, you decide who powers it. So while we hope you’ll stay with us, if your trial has ended, you’re welcome to change who supplies your home. We’re proud to power your home and EV We hope you’ll stay when your trial ends, but if you did decide to leave OVO Energy, while you’ll keep your charger, you won’t be able to log into the V2G app powered by Kaluza. This means your charger will lose its smart features and you won’t earn OVO V2G credits. We’ll also have to delete
We have this year installed solar panels and storage batteries to supply an alternative 240 volt circuit to part of the house to reduce our electricity cost. This has worked out well and our electricty supplied by OVO has dramatically reduced. Now OVO on entering the latest meter reading is questioning our low meter readings.Any advice on how we proceed with this? We have no issue with the company inspecting our meter or checking out our solar system.
I have an outstanding problem concerning FIT payments for several periods whilst my smart meter was faulty and subsequently replaced. Despite sending numerous emails and trying to make contact by phone, I am getting no answers or response. Is there a problem at OVO
What's the most cost effective way to heat your home with an air source heat pump (ASHP)?SHARE YOUR EXPERIENCE
Updated on 19/04/22 by Jess_OVO Heating strategies with an air source heat pump Air Source Heat Pumps (ASHP for short) offer a great chance for us to decarbonise how we heat our homes, as they’re designed to heat your home efficiently using electricity rather than fossil fuels like gas boilers. We’re lucky to have lots of heat pump owners here on the OVO online community. They’ve already been sharing some great insight into life with a heat pump for those who might be considering making the ASHP leap. We heard from two of them, @hydrosam and @hambrook, in our most recent online event on the 2nd of March (we’re hoping to publish a summary of themes and insights soon). That event has inspired the topic of our next ‘Share your experience’: heating strategies. After you’ve made the decision, accessed any relevant grants and the excitement of installation day has been and gone - you might be wondering exactly how this new heating system works best.
