ASHP - Freezing temperatures

[richo106]

Hi All

 

I have had my ASHP commissioned and had it running for a few weeks however since 1st Jan i have had to turn it off so my ground floor can be tiled. My ground floor will be finished tiling today but the tiler said to wait another 14 days before turning any heat on!

 

I haven't got any anti freeze in my ASHP system currently - I am panicking a bit with the freezing temperatures we have been having that it may cause damage to something

 

Is this something I should be worried about? Is there anything i can do over the next week or so to help negate any issues I may have?

 

Many Thanks

If you have no glycol you should have  anti freeze valves.

 

Is there another zone that isn’t getting tiled that can let the heat pump work?

 

Get  in writing what the process is for re introducing the heat, how many degree per day over what period might save a lot of grief later…

 

good luck

Spoken to my installer and tiler…hopefully all sorted now

 

Many Thanks

By off, do you mean standby or fully powered off?

Yes, was it off, or off off?

Some heat pumps have a special screed drying programme which increases the slab temperature slowly over a period of two weeks or so, this might be suitable if your tiler agrees.

Apologies for the terrible (rushed) first post - My ASHP was in stand-by (off at the controller but on at the isolators)

 

I have spoken to my installer and I have now turned on my ASHP on and left it to heat the buffer tank with the UFH re-circ pump off

 

Many Thanks for the quick replies
