It would seem a sensor was out of reach. "way out" he told me.
Part ordered so hopefully will be sorted by next week.
Thanks for the help.0 -

Oh this is good... Glad it is something simple.
Let us know how u get on when the part is replaced. Do you know which sensor?If you found my post helpful, please remember to press the THANKS button! --->0 -
I have an ASHP installed in our newly built house here in Austria. Up a mountain! So all through the winter months it was very very cold.
The system is a Hoval Belaria . and seems to work well.
Our house is mega insulated and has under floor heating, which I gather is the correct heating system. We were told radiators are not efficient for ASHP. The house is always cosy and warm, and we were advised it would work more efficiently if we kept it on all the time. It also supplies our DHW.
Any questions ??0 -

Even if it was 50mm above the ice would still build up.
Sensors I agree can and do go wrong I just wouldnt expect it on a new unit but if they still cant find the fault after checking the sensors etc then given the unit is new they need to replace it.
No problem. The 50mm is the minimum level as with most specifications. Higher is better for airflow.
Sensors even on new units can go faulty. If the installation company cannot trace the fault, then they may not be competant enough. We will spend hours trying to find a fault and if it is totaly unresolved the unit is replaced under the 5 year guarantee. All costs are paid by us, including if the client has to go to electrical backup heating during the downtime.
Does this happen in the UK?As Manuel says in Fawlty Towers: " I Know Nothing"0 -

No questions. You should let it run 24/7 as that is the design criteria. You can reduce flow temps overnight for sleeping and if you have a DHW tank, then use the timer, so not keeping the water hot overnight.As Manuel says in Fawlty Towers: " I Know Nothing"0 -

Yes, I have. Would not touch it and we do not have a system on sale here anything like it.
12 years of purely Geothermal heating systems and IVT who we use does not make a similar unit ........... wonder why?As Manuel says in Fawlty Towers: " I Know Nothing"0 -
Well
Just read through thge entire thread over the last few days
It was interesting to see the change in positivity over the years with some users and at one point I was as one poster said , thinking it has to be a no brainer.
I am in Bulgaria and was looking into air to air , but it seems the cold winters here may be a problem as sometimes we get down to -20 - 25
At the same time in december the temperature can also be 19 degrees in the sun with snow on the ground and an air temp of around 7
I have a 34kw wood burning stove that runs 13 radiators, insulation middling, and size of house 300sq metres on two floors
I am thinking of using a few air con type units that they sell in our equivalent to B&Q for around 750 pounds
Electric here is 11 stotinki per kwh which is around 5p and night time rate is around half that
Obviously wood is cheaper but we get some very mild days in november, december , jan and feb mixed in with the cold
I was thinking that maybe this would be ideal for the air con units
It is a complex area though having read through this thread0 -
I reckon that's the right way to go;
Buy cheap air/air units as a supplement to another heating source (wood in your case).
Use them intelligently to get the best out of mild weather, and don't run them hard when it's very cold.
I paid 800 Euros each all in for 3 x 5kW units. I don't think they're especially reliable, but by my calculations they only have to last 2 years to have paid for themselves.0 -
