Today the temperature has risen to around 7 degrees outside. The new setpoint of 43 dgrees is being achieved. The room thermostat is set to 17 degrees now, but only acieving 16 degrees, which is more comfortable than the 13 degrees yesterday. Electricity used in the last 24 hours is down to 67 kWh, which is an improvement. Maybe the setpoint was too low. Should i increase it again to see what happens? Attached are imaghes of the sensor menu. Best wishe. Tog 🙂

Aroound 1800 ltrs. The boiler was a condensing type

I used to spend around £1,400 a year on oil, but I had control over it, being able to set a timer for 4 times a day, and override manually when needed. With the ASHP I have no control. I just have to let it run continuously. How can I tell if a backup heater is being used?

Hello. No error codes shown, and we did have a Daikin sales engineer visit with the installer to check in December because I complained that the cost went up and the temperature went down. He said the system was set up OK and left the setpoint at 39 degrees. Now the installer and Daikin are not responding to my emails. Maybe I am just being a pest, but they told me it would save money, and it isn't. The heat pump is 11KW ( EBLA 11 DAV 3) All rooms except for kitchen and bathroom have insulation on external walls Plasterboard with polyurethane. Floor area is 158 m2 and the output on the project form is stated as 12785. The unit is fixed setpoint, not weather dependent. The unit is on all the time and the thermostat is also on all the time (no timer) I now have the thermostat set to 17 degrees, but it won't get there (13.5 right now) The unit often makes loud noise, like car with choke on. Unit does reach 39 degrees sometimes, but fluctates between 34 and 39 (I don't understand why this is) Unit has auto defrost. Sometimes it dumps water to prevent freezing, and this requires radiators bleeding and topping up pressure to around 1.4 bar. I have increased the setpoint to 43 degrees, but if it can't achieve 39, it doesn't seem logical that it will achieve 43. Flow rate shows 21, and the flow switch (whatever that is) is marked as "off". Heating is using around 100kw a day, but rooms are cold with thermostat only reaching 13.5 degrees. Best wishes. Tog 🙂

Helo. I am not a professional, just a householder. My hpouise is an old barn with very thick stone walls. I had a Daikin Altherma 3 ystem fitted in the summer under the ECO4 system. The installer has created 2 zones (upstairs and downstairs). They also fitted new radiators , solar panels, and wall insulation throughout the house. I previously had oil fired heating and changed because the installer said an ASHP system would save me money. Now we have snow and freezing temperatures outside, it seems that we have serious heating problems. The setpoint is set to 39 degress, but the Daikin control panel shows an actual temperature of only 34 degrees. Does this indicate a fault with the system? I have emailed the installer and Daikin, but not redceived an answer. The third party thermostats (one for each zone) are set to 15.5 degrees, but only 13.5 degrees is being achieved. The actual room temperatures are down as low as 11 degrees, whereas before the cold weather they were reaching a comfortable 17+ degrees. The radiators have been bled and the pressure is fine at 1.4 bar. So, our heating is not reaching comfortable levels any more, yet the cost has jumped astronomically to £29 a day (equivalent to over £800 a month) I am a pensioner (71) and cannot afford to pay that kind of money, and for a cold house to boot. Can anyone advise on what action, if any, I should take? If the tank temperature will not reach the setpoint, I am wondering if the unit may be the wrong size for my house. How can I tell? Many thnaks and best wishes. Tog 🙂
