no hot water Mitsubsihi Ecodan, Emergency mode 

Hey @jayedgardyson1920, Yes absolutely ! when you press and hold the tap symbol on the wireless remote, this is a 1 hour boost function, so even if your hot water is set to a timer, and you reuqire hot water outside of the timed period, for example during peak times or when you have more usage, the tank will heat to the required temperature and automatically switch off. things will then revert back to normal :) . also thanks for your feedback, it is much appreciated.

also, just an afterthought, have you changed the settings as shown in this video because you've not been getting hot water ? this video is generally for emergencies only which may mean you have an issue with the heat pump?

Heya, make sure you press and hold the note pad button until it prompts you into the next menu then go to hot water and you should see the note pad button icon

Hi Stephen, is it the Mitsubishi wireless stat you are using or 3rd party controls such as honeywell etc ?

@@leshutch3166 heya, it sounds like your heat pump has an issue if it's bringing on the immersion during normal operation, after a certain amount of time during hot water, if the heat pump doesn't provide enough temperature to increase the tank temp, it will usually revert back to the immersion. I would get an installer to take a look for you !

No bother will do thanks for the help👍

sounds like your 3 port valve is faulty, if its working in heating but not hot water it means the flow rate isnt there when in hot water mode.

Hello. Today I've acquired the new valve. I'll replace it tomorrow

@@robertoleszek8361 let me know how you get on, hope all goes well

@@renewableheatingengineer8537 so the valve wasn't the issue, I've used a Central heating cleaner. After a treatment I've washed the system. There was a lot of black sediment. I mean a lot. Now system works as usual.

no,you need to change this back to standard once the heat pump is fixed

Hi Lisa, I would say this is your legionnaires cycle kicking in. Check out my video on setting legionnaires and turn it off if you wish .. this will stop that heating up when your not calling for it.

@@renewableheatingengineer8537 It was thank you! I’ve put it to every 15 days instead of 7. I was trying to work out how much it costs to heat water an hour everyday when it doesn’t get used ? And just over run it if I wanted a bath not electric shower. Cheers ! Heating not on yet…I find it very expensive even at 17 degrees 😕 Great videos !

Hi Matthew, based in Lincolnshire.

Hi David, Usually we see this comment when the customer has been let down by the installer, could you provide a brief description of your issues, experience, the technology and manufacturers take a pasting unfortunately usually down to the installers them selves...
