Forgive me if this is in the wrong section but this is my first post.

My Daikin Alterma seems to be working but I don't have much heat coming through the radiators.

Please can someone tell me if the figures in the attached photo are correct and if not tell me how I can fix this?

Many thanks in advance :)

Are you maintaining the desired indoor temperature?

During milder weather the heat loss from your home will be much lower, so your radiators do not need to be very warm.

Hi @uffda. Would you like me to put you in touch with Daikin and their engineer to help sort this out?

@uffda I’ve just received a message from Daikin who have kindly offered to send out an engineer to you to see if they can resolve the issue. Please let me know if this is of interest.

That’s a daikin hybrid system which uses an intergas boiler as the gas fired bit.

looks like it’s firing at 31 degrees flow temp, which is probably about right depending on your radiator sizing and the outside temp when you took that photo.

I prefer to spend a bit more on running costs and have my weather comp bottom out at 38.5 degree flow, as you can at least feel that temp flowing through the rads.

@uffda welcome to the forums. Is this something that has started recently and the rads were fine up until now?
