    has anybody out there installed/ heard of neura heatpumps?
    seem like a really good pump, that use gas instead of liquid in the ground loop. have been told they have a cop of 5.5, which seems hard to believe when most other systems are around a cop of 4.
    any opinions?

    It has shill written on it but there may be a simple enough reason for posting here.

    Perhaps frankie2shoes could PM smashey with an explanation otherwise it stays locked.

    Don't worry Frankie. We might have been a bit over cautious earlier.

    Frankie these are Direct Expansion or D/X heatpumps.

    A COP of 4 is generally what you will get with a brine (anti freeze and water mix) or liquid as you call it, the DX will produce anything from 4.5 up to 6.5 depending on the heat pump and whether or not it is AIR, water, ground or vertical.

    Also a DX system does not need a circulating pump to push around the gas as the brines system does so you will get a higher performance.

    BTW - I have heard that the neura are a good heat pump, but also that the DX is available from other manufacturers also so keep that in mind when you are looking for quotes, specifically ask them to quote you for a brine and a direct expansion heatpump, if the provide them.

    Also get the COP figures off them for the brine and the DX
