I have done some reading on here and followed advice from other posters but I wanted to check to see if I have things setup right.

 

  • Goals
    • Be economical, not wasteful
    • Keep temperature in the house at 22-23 degrees C
    • Have hot water in the morning for showers and in the evening for bath for children
  • Heating Setup
    • I have it set to Compensation Curve, at 14 degrees external or below the temp is at 46 degrees for the rads (at least that’s how I understand it works)
    • Thermostats are Heatmister Slimline, they are set at 23 degrees to knock off the rads if it gets too warm
    • This setting is 24/7, I read that its better to keep the house at the same temp all the time. Plus we work from home all the time so don’t want it cooling during the day.
  • Hot Water Setup
    • I had it to warm the 200L tank up to 50 degrees between 2am and 4am, and to come on once the temp dropped 10 degrees but only during this time.
    • I noticed that this was perfect for morning showers - temp had dropped to 47 degrees by 8am which was fine but it meant in the evening it was down to 27 degrees, too cold for a bath.
    • I changed the setup so that it comes on at 2am and will keep it at 45 degrees (again only turning on once it drops to 35 degrees or below) until 9pm.
    • I was working off the same theory on the Heating, that keeping it ticking over all day between 35 and 45 is using less energy than letting it go down to 24/25 and heating back up to 50 degrees at night.  
    • The reason for 2am - 4am is that is the cheapest window to use electricity

 

So, just trying to see if I should be doing something differently?  I live in Ireland, new build house this year and we have a plug-in hybrid car.  Our 2 monthly bill is around 370euro - this includes heating, hot water, cooking, dishwasher (almost every night at the cheap hours), washing machine (every night at the cheap hours), and charging the car (at cheap night hours), and the usual lights, kettle, TV, computers, etc.  As we are home we probably run the kettle and electric hobs a lot more than normal.

 

I want to help keep down the bills as much as I can and previous to this we had a gas burner which was basically instant hot water so I am trying to shed the old way of doing things and learn the new and become good at it.

 

I have read people say once they get this setup right for themselves they can essentially walk away and thats done and dusted.

 

Thanks,

Hmmmm

 

Well, Ecodan is supposed to be smart😅 and regulate this based upon max temp and temp drop for DHW.

There are some settings for timer as well that I haven't set up, but I can look into that as well. Not sure if I will run out of DHW if I have it on restricted runs...


I have mine set to ‘schedule and reheat’ which means if the tank temp drops below a given setting (30 deg in my case) it will reheat to 40 deg. For a scheduled heat the tank temp is 49 deg, actually it very rarely triggers a reheat. The tank is 210 litres, it loses very little heat as is well insulated.


Hi there!

I have been looking at my hourly temps with the Home Assistant integration and it looks like there is a constant swing in temps, almost 10 degrees ever 30 minutes. Then overnight it settles.

I have WC set to 45 @ 0 and 25 @ 20 home heats well and energy usage seems OK. Just trying to understand if this is a problem or if there is something I can do to increase efficiency? Also why the flattening of the curve over night?

 


Hey @razor 

 

Really great question on the flow temperatures.

 

We’ve had some really good conversations from other users previously on flow temperatures on heat pumps, and even specifically on the Ecodan itself. I’ve linked below to some of those helpful topics:

 

 

There’s also lots of community members who may be able to give their own perspective of things, @M.isterW @amanda1 @Ecodanwarrior, any thoughts would be appreciated.

 

Hopefully some of the topics are helpful to you, I know it’s been a fairly common question on the Forum.
