Thanks for sharing the stats - having seen one of your previous videos and learning about R290 I bought the 3.5kW ElectriQ - I’ve yet to install it but the idea is to use is to cool over the summer using my PV which I have in excess and the same to heat in spring and autumn - had it not been for the low price (£600) and the ability to DIY due to not being f-gas I’d probably not have bothered 👍
@@HEATSEEKER1428 thanks for the tip - 65mm looks like the closest one, though it does feel a bit annoying spending £45 on the bit and extension just to cut one hole, so I'm trying to find someone who might have one to borrow nearby!
Hi I have this unit the 12000, mine had a leak and was repaired it’s been regased, but when running it doesn’t get hot, would know what the standing and running PSI should be to determine if we have too much or too less gas thanks
Hi unfortunately I don't have the the pressures . You must follow manufacturers instructions but I would say if your indoor unit and your out door unit are running and you have the correct mode selected and your filter in the indoor unit is clean then you have very low refrigerant levels . if this is the case then I would check for possible leaks , Using either a vacuum pump or air pump of some description . Obviously not R290 . Thank you and good luck 👍
Possibly a silly question but does the internal unit have to be up high on the wall? I want to go this route but don't think it enhances the look of a room in an older `rustic' cottage. Thanks for the informative videos on fitting.
Hi Not a silly question at all .I have had thoughts on this my self. I think as long as you fulfil the clearance criteria in the manufacturers instructions and the proposed fitting location is safe you should be ok. Appliances direct sell an all in one unit that can be installed at high or low level . Thank you and good luck 👍
@@HEATSEEKER1428 Thanks for the swift response. I perhaps should have said that my prime objective is heating not cooling. We all know about radiant heat & convection currents etc that affect how comfortable a room might feel, but I wonder if these systems have the room unit high up because of how the heat provided circulates around the room. I'm guessing here, & need to further research the science behind the best positioning of the indoor unit. Maybe it would be draughty if positioned nearer the floor. Anyway, I have another question. What is the maximum temperature rise the unit can provide between the air surrounding the heat pump outside & the unit inside? For example, if on a frosty night the outside air temp' was (say) -7 deg C, what is the highest temperature of the air produced by the unit inside the house? Your energy usage notes were taken in some winter months - did you have any particularly cold nights to assess this?
Hi The manufactures instructions state that the unit is efficient to -5c. the units are designed to heat spaces no larger than a given size. so my understanding is that for every degree below -5 then the targeted inside temp will coincide. i.e If your target temp inside is 24c and the outside air temp is -7c. then inside temp will only reach 22c.. Of course this all depends on insulation levels and if your heat pump is correctly sized. Regarding my experience of heat pumps performance in very cold weather I don't think the COP went much below 4 if at all. I will see if I can find some info. Thank you
Hi, thanks for the update. I am considering buying one of these and fitting it myself as I'm a competent DIY'r. I had a few questions if that's ok? 1. I believe these can be installed without a vacuum. Is this done by purging the system and essentially removing any air by ejecting some R290 out the exit pipe? 2. I will mainly be using it for air conditioning. Does it produce really cold air? What's been your experience with it? Thanks, Keith
Hi You are right there is no need to vacuum down the pipe set . The instructions go through this procedure. Regarding the cooling capability's I have only tried it briefly . According to the manufacturers in the unit is more efficient in cooling mode , so I don't think you will have any problems . Thank you and good luck 👍
Thanks for the update on the outside unit. The video would have been better if you wasn’t speaking over the top as it’s covering up the sound of the unit - which is what you was showing. Otherwise great update

Hi I don.t think you will be disappointed you have purchased great product. Good luck👍
Hi You won't be disappointed these heat pumps are reasonably priced ,easy to install and very economical to run . thank you and good luck 👍
@@HEATSEEKER1428 yep it’s on my job list- only daunting bit is core drilling the 63mm hole through the wall 😵💫
@@Umski Hi good luck . I have to say I found 6 3mm a bit tight if you are buying the core bit especially you could go a bit larger . Thank you 👍

Ok Thank you I take your point but there really ws not a lot to hear . Just the sound of air flowing over obsticals . Thank You
