update: plumber came this morning and the little pump inside the outside unit has been replaced and it's now working. unfortunately it was wife that was home to attend and i didn't had the chance to see how to replace and where to buy a new pump in case this happens again

yes, wife did yesterday but I just did it again after you mentioned and upstairs they all hissed and came out water which is good i guess. Downstairs they didn't hiss but water came off. I've done a reset once again but still same error code.

@JohnMo turn both valves and let pressure went up to 1.5 as you can see in pic and reset the system. still showing same error h20.

Both valves? okey dokey, will try tomorrow! Damn, I love this forum. People are so kind and helpful, unfortunately I'm not skilled enough in any of these topics as I would love to help people like this

Thank you for the quick reply, currently working a night shift. Will try tomorrow. Before I left home, i've turned the switch which i think it's the immersion for hot water but radiators were still very cold althought the live usage on octopus app was showing more than 4000w, so I told wife to turn it off since it's not warming up the house. When she turn the switch off, she said something sparked around the switch, so not sure. I am not sure which one I need to turn to top-up water, tomorrow will take a couple pictures. When saying "switch off power to heat pump" do I actually turn it off in the meter box or just turn it off in the thermostat?

I will tomorrow, currently doing a night shift. Thank you for the quick reply!

@JohnMo Hi everyone, I completely forgot about this topic as eventually I saw that many people were spending much more money than me, I'm only spending between £100 and £150 in this weather while I see people spending over £200/£300 which is crazy. I have a new issue, this H20 and H62 error came up yesterday and house has been cold and no hot water, I need to shower my son asap. I've cleaned the filter as seen in the picture but still not working. Radiators have been bleeded, some of them no hissing and no water coming off. What else should I do? Please help

@JohnMo this is my setup

@ProDave by using the weekly timer, i've stopped the hot water running between 4-7 before but eventually when having a shower the hot water would stop on the second/third shower

@Beelbeebub hi thanks for the input! i'm sure the hot water is at 2AM but still having showers at 6/7pm costs immensely! on the weekly timer do i turn off hot water between 4-7? i think i've done that before but when we were having a shower, hot water was gone after a while

@Marvin How this affects your energy bills An average household would need to spend £490 per year on heating, hot water and lighting in this property. These costs usually make up the majority of your energy bills. You could save £0 per year if you complete the suggested steps for improving this property’s energy rating. This is based on average costs in 2024 when this EPC was created. People living at the property may use different amounts of energy for heating, hot water and lighting. My doesn't show those kWh per year for heating and hot water for some reason

Hi, is that on the epc website as well? couldn't see that

@JohnMo working all day today, will try to have those pictures tomorrow morning and see if i can use the controller. my controller is not the same as the video one but should still be able to do it

@marshian i have no idea the temps of each single room, only have 1 thermostat in the lounge. It feels colder in our main room, baby bedroom ( which both are upstairs ) and i guess the lounge which has french doors and a view to a field

@ProDave yes! that's actually something i don't really understand why we spending so much when having showers if the water is already hot. how do i adjust the timer for the water heating? i think from what i remember, they set it up for 2am tho, so not sure how it's still working during shower times
