ProDave Posted October 5, 2018 Share Posted October 5, 2018 It's a split system so will probably need re gassing. Link to comment Share on other sites More sharing options...
Triassic Posted October 5, 2018 Share Posted October 5, 2018 Oh, I missed that, I'm sure I read is monobloc? Link to comment Share on other sites More sharing options...
ProDave Posted October 5, 2018 Share Posted October 5, 2018 Viessmann Air Source Heat Pump complete with Indoor Unit & 200L Viessmann Buffer Tank. Buffer Tank Model - VC100-ESWV 200L. Air Source Model - Vitocal 200 - S/222/S/242/S Removed from a new build property due to gas boiler installations. Products have been used for approximately 4months. £500.00 If it's monoblock, then what is the "inside unit" looks like a split system to me. Why was it only used 4 months?

Why was it only used 4 months? Could be a hydronic unit, perhaps? That's an option for the monoblock we have. Essentially it's just a heat exchanger arrangement that keeps the DHW and heating circuits separate in the house, I think (not bothered to look at it closely).

Triassic Posted October 5, 2018 Share Posted October 5, 2018 Found this image online. The indoor box is a heat exchanger and controls . Its only four months old because the owner wanted an old-fashioned gas combi. Link to comment Share on other sites More sharing options...
Jeremy Harris Posted October 5, 2018 Share Posted October 5, 2018 That looks like the optional hydronic unit for our unit that I mentioned, I think. Link to comment Share on other sites More sharing options...
Triassic Posted October 5, 2018 Share Posted October 5, 2018 The seller tells me the heat pump is 4.5kw power consumption, heating output is 7.7kw. Does that sound right? Link to comment Share on other sites More sharing options...

Jeremy Harris Posted October 5, 2018 Share Posted October 5, 2018 Looking at that data it's a split, with the refrigerant circuit coming indoors to the heat exchanger, so it needs gassing after install, which means getting an F gas qualified person to vacuum it out, fill it and leak test it. I think I'd be very concerned about how the refrigerant pipes have been capped off and sealed when the unit was taken out. If they have been left open then the unit may well just be scrap, as it only takes a small amount of moisture to get into the refrigerant circuit on the heat pump itself to do damage. If the pipes have been left open then the oil in the pump may well have absorbed moisture, or even been contaminated by dirt and dust during removal, so there's no telling how reliable it may be.

ProDave Posted October 5, 2018 Share Posted October 5, 2018 I would love to know the back story. Is this a new house or was it fitted to an older house? Who paid for it and why was it ripped out in preference for a gas boiler just 4 months later? Link to comment Share on other sites More sharing options...

Phah, cup half-empty kind-a-guy. but seriousl, i guess you could ask the seller for some proper pics of the pipes. You could possibly take a punt if they look ok. 1 minute ago, ProDave said: I would love to know the back story. Is this a new house or was it fitted to an older house?

Gav_P Posted October 5, 2018 Share Posted October 5, 2018 (edited) Isn’t it a brine system. So gas shouldn’t be an issue? Edited October 5, 2018 by Gav_P Link to comment Share on other sites More sharing options...

No, it's definitely a split - see pages 34/35 of the pdf that you linked to above. The refrigerant pipes come inside the house to the indoor unit, with its refrigerant to water heat exchanger.

Gav_P Posted October 5, 2018 Share Posted October 5, 2018 Ah yes. The selling point of not needing frost protection on the connection pipes should have also made that clear to me! Link to comment Share on other sites More sharing options...

This is the IVT that a few have - @readiescards has one. Let’s just say that’s about double though on price to what others have paid ..! They are a 9 year old unit that is split from a tank system - no longer sold but under the covers they are a Mitsubishi unit. Link to comment Share on other sites More sharing options...
Onoff Posted November 24, 2018 Share Posted November 24, 2018 This one's near me. Guessing English isn't the lads first language. Have to wonder what heating etc he'll have when it goes! https://www.gumtree.com/p/plumbing-central-heating/air-source-heat-pump/1321518960 Maybe he's renting the house!

vfrdave Posted November 24, 2018 Share Posted November 24, 2018 It escaped me that it was 9 years old I'm guessing not as efficient as a newer one. As you say @PeterW wouldn't want to pay that much, they are open to offers it seems. Link to comment Share on other sites More sharing options...
