Hi all, we seem to be possibly the only trialists with a Daikin Altherma 3 and Sunamp combination and although the system is functioning and supplying all our needs my question is has anyone received their yearly service / maintainance yet regarding the indoor and outdoor units and if they have what did it consist of? as i have had mine and the engineer was at a loss to identify any part of the system that needed servicing! any help or guidance would be greatly appreciated, Dave.

Hi, has anyone managed to use charge anytime with their Polestar 2. It doesn’t seem to be a choice for me?

Noticed this morning that the blue flame was showing about 0.08p per kWh. We haven’t used any hot water for at least 45 mins yet still shows usage, dropping down to 0.02p now. At a loss what’s happening. It has been off and then back on again after using some hot water. Not radiators as they’re definitely off

I have just had solar panels fitted what do i need to do next, I have yet to contact OVO . My meter readings are going backwards

Hi, I’m having trouble differentiating which switch is which with my Quantum storage heaters. I know they one is on peak and one is off-peak, but only one switch lights up and turns on the digital display, while the other switch seems to do nothing when switched on its own. Any advice?? I don’t want to be paying for on peak 24/7 by mistake 😖

I reported my Smart Meter was not working in July last year. Nothing has been done about it, though every month I get an email message about the need to supply readings, which is kind of annoying. The screen on the meter is dead so not even manual readings are possible. When chasing some action on this I received a reply in November saying there was a queue for meters to be fixed, but I would be notified as soon as an engineer was available. As it is now April, it must be some long queue.

I have underfloor heating in my flat which had night rate settings on the old meter. Which means the heating comes on between 12 midnight to 7.30 am. I have a smart meter now but being 63 and feeling the cold i need the underfloor heating coming on during the day. I need OVO to change my settings or explain to me the situation, do i need a new tariff etcBUT after 2 long conversations with OVO staff who couldn't help at the time but promised to get back to me(they haven't) with information.Anybody else had the same problems as i need to sort this out before winter

Hi I was wondering if anyone could help me. I have bought one of these meters on ebay but cannot find out how to connect it. No wifi menu in the settings.

When i have to put the heating on with my combi boiler is it cheaper to have the boiler set at 70 eco with less radiators on, or at 50 with more radiators on? My boiler man has serviced the boiler and set it to 70 eco for when i need the heating on. Any ideas welcome please! 

Good morning, I moved into our new home about a year ago and have really struggled with finding meter readings from the solar panels.I don’t really k ow which box I should be looking at and what numbers they need. Any advice would be greatly received.

Hi so I have has solar panels fitted last October 2022. I have 2 tariffs a day time tariff and an economy tariff that kicks in from midnight until 7am. This is when my battery recharged ready to work from 7pm until the solar panels take over. However I take a reading every night before I go to bed and one again as soon as I wake up. My economy rate goes up in the night by about 4/5kw but my problem is every night my day time rate moves up 10kw. Nobody knows the answer as to why and the electricity company do not seem interested. Can anybody help me I now have about 6 months of data and can’t get a resolution. Can anybody please help me 

HI,I’ve got an old stone house and we’ve been looking at getting an ASHP installed, we have a quote for a dual 22kw ASHP arrangement. Just wanting to know if anyone else has any experience in running a larger setup? We have an 11kw turbine on-site so this should hopefully take some of the load and will perhaps look to install 5-10kw of solar to supplement. On a good day we can generate ~200kw of wind power.. 

Does anyone know roughly how much electricity is used annually if the gas central heating boiler is left on permanently, thermostatically controlled? Is there a saving to be made by switching off completely during the warmer months?  

I was reading this thread and all my lights flash once every 1 second. My HID shows old supplier for electric ( moved last week) gas shows current, is this normal while the electric meter gets picked up with new supplier?  

After my smart meters installation, My OVO payment site tells me that there is no meter found for electricity. But it is logging the usage . So I need advice if you need meter reading or not.

I have solar panels and a battery, and a smart meter. I don’t have an EV. I’m on a simpler energy tariff with OVO which costs 25.86p a kwh. I’ve seen tariffs elsewhere which offer a cheaper rate to allow me to recharge my battery for a few hours a night; and thereby maximise use of my battery, and increase my savings. Does OVO provide such a tariff? If not, then why not? Especially since they appear to offer such a tariff for ev owners. I’d rather stay with OVO but if there is a better deal elsewhere, then I’ll jump! 

Hi.  I am trying to see the ‘Energy to User’ data so that I can download it together with the ‘Energy from Grid’ data and then can calculate the energy provided by the panels and inverter.   Does anyone know why I can’t see the Energy to user data please?thank you in advance for the help.    

Recently tried installing Tado v3+ wireless starter kit but left me with no power to boiler worked out the cable asked to replace in instructions was power to boiler so put both Tado and boiler L and N cables in the relivant ports in boiler and had powerhowever when it came to test, boiler didn’t fire. was previously using Salus RT520 thermostat, unsure whether this is wired or wireless to boiler tried the Tado support with no luck, they didn’t seem to understand.

Where to find serial number. On edmi es 10 b

Hi, I’m hoping for some help in finding a system that allows me to monitor and adjust house temperature remotely. The house is heated via an Ecodan air source heat pump with underfloor heating downstairs and radiators upstairs. Currently we have one wireless thermostat which allows us to set programmes as well as measure the temperature for a target in whichever room we leave it.  I don’t think we need anything complicated, but want to be able to adjust the target temperature and programmes remotely. Even being able to initiate a hold temperature remotely and then cancel it again to engage the programmed settings would be fine.  I’ve had a look at various smart thermostats but compatibility seems to be an issue and the in-house app by Mitsubishi gets aweful reviews.  Any help or advice very gratefully received! Thanks in advance!

Hi , I wondered if anyone else had come across this problem. I’ve repeatedly contacted customer service to ask for a smart meter as the online booking won’t let me. Each time they have told me there is an issue. But they can’t tell me what the issue is. They first asked if I’d ordered one before then not allowed access or something - I pointed out no,  I’d only just bought the house and never had an account with them before. Next time they told me it was a problem with all smart meter installations. Next time when pressed and pressed they admitted it was just mine. But each time they say they don’t know what the problem is and will pass it on to be sorted  and someone willget back to me - which they never do. Last time they told me that the request for it to be sorted had simply been cancelled. Do I need to change suppliers to get a smart meter? 

HiThe FIT meter for my solar panels have stopped working. It is showing the same reading since June 2023 which is 3 months ago.Who do you contact? Is it OVO or do I need to get in touch with an electrician?ThanksB Burnett

Hi,The electricity readings on the OVO website have started to look funny. Here are July and August. July looks fine. August looks wrong. (Half of May and June is also wrong)Any ideas? Thanks. Mike  

Over the last few years I’ve had more and more electrical stuff installed - outside room power, electric oven, EV charger and heat pump. To accommodate these my consumer unit (new 20 years ago) has spawned baby consumer units, three to date. Now I’d like to get solar and battery so I’ve been advised to get a new larger consumer unit which will supply all these, plus some spare ways for the future. The electrician has given me a quote for this but also given the option of an Arc Fault Detection version which is considerably more expensive. I’ve read that this is required for multi occupancy residences (which we are not) but also guards against arcing due to rodent damage etc. Would it be a good investment or is it a bit unnecessary? Any advice would be welcome.
