Air source heat pump

woodbeast

Really need help. My air source heat pump is broken. It is still under warranty. I have contacted Daikin UK multiple times to arrange for engineer to repair. They are completely ignoring me. Meanwhile, heating system has gone into emergency mode and has run up £700.00 over the last 3 weeks. Any help much appreciated I can't sleep for worrying about electric bill.

I presume "emergency mode" means it is using an internal resistance heater.  You would be better off switching off the heat pump and using fan heater to heat the rooms you occupy and the immersion heater to heat your hot water as necessary.

I don't know what to suggest regarding your impasse with Daiken.  Is it their responsibility to fix the ASHP or should your installer be taking action?

My air source heat pump is broken.  It is still under warranty. It has cost me over £700 for the last 3 weeks. It has gone into "emergency mode". I am disabled and Daikin UK are not arranging for it to be repaired. Has anyone else had any issues with Daikin UK. Worried about not being able to pay electricity bill .

The installer says its Daikin as the system is still under warranty. The installer was an accredited installer but basically a plumber. He has no knowledge about repairing. I don't understand how the system works but I think if we switch off at the mains we will have not have hot water for showering. Even if they phoned and told us what to do it would help. But nothing. Utterly disgusted with them . We have had to turn down all the radiators to zero as the house was roasting, but obviously its still using all the power...hence the £700.00 deficit on my electricity account. Honestly worried to death about stacking up huge bill.

Hi woodbeast, do you have a controller on the ASHP where you can turn off the heating.

Did your installer complete the warranty info with Daikin when it was installed or did you have to do this manually after?

The installer completed the warranty. We have turned the digital thermometer down to off. But it is still "on". There is a big white unit in the cupboard which should have a blue light on..but it's red at the moment cos it's broken.  The fan outside is not turning around at all. Sorry I'm not technical.

How have you contacted Daikin and what has been said if anything?

If you can provide more details.such as make and model and type of controller (module). Also do you have any manuals and troubleshooting guides to read about the fault you are experiencing.

It's not pretty reading on trustpilot to be honest

It's a Daikin R32 inverter. With honeywell control clock. I have phoned them multiple times. I have a job number but I am waiting for engineer to call me to book home visit for repairs. Installer thinks the pcb board has gone in the main unit outside. So the outside unit is not "talking " to the inside unit and has gone into emergency mode. I am also waiting for Daikin technical depth to call to see what will happen if we shut the unit down completely outside due to increase in running costs. We are based in North East Scotland. Thank you for your interest..honestly feel like I am hitting my head off a brick wall with Daikin.

Heat pumps should be able to handle power cut incidents so if it is costing you a fortune you could flip the heatpump switch on your fuse.board.

It is probably best to wait for the temperatures to not be freezing though as no frost protection will kick in.

Alternatively The Honeywell controller (I presume you mean a programmer where you can set times of heating and temps and not just a temperature sensor) should allow.you to turn heating off completely if it is costing you a fortune and also program the hot water if required to run off the backup electric heater.

How long has it been since you contacted Daikin?

@woodbeast

if you join https://renewableheatinghub.co.uk/forums and post there, there are some folks with Daikin ASHPs who can help with specifics.  There are also people who may be able to influence manufacturers if all else fails.
