Chiltrix Units

Hi,
Anyone care to share there experience with Chiltrix. Its for a home in New England (region 5). Does this have any advantages over conventional heat pumps or mini splits? This house will perform at approx. one (1) ACH or less and is under construction now, so making a decision is necessary shortly. Do we need any special arrangement using this brand of heat pump..? Here is a link http://www.chiltrix.com/documents/price-list.html

    I have no experence with them.

    There claim to fame seems to be that you can run longer line lengths because your pumping water instead of refrigerant. I would think they would be more expensive to purchase

    Serviceability could be an issue, there got to be a lot of stuff packed into the condensing unit.
    water pump
    refrigerant to water heat exchanger etc. etc

    I am sure that their are some applications where they could be better than a traditional ductless split

    Sounds reasonable....thanks very much! That's exactly what we were looking to find out, also should a plumbing contractor be responsible for installing all major components including ERV distribution sys..?

    LOL. I got in trouble a few weeks ago because some on this site thought I was disparaging plumbers.

    All I can say is you need a qualified installer. Maybe the manufacturer can point you in the right direction.

    I'll just say this at the risk of incoming flack.

    A typical plumber that only does sinks, toilets etc. would not be a good choice. You need someone with HVAC experience it may or may not be a plumber, or an HVAC service company etc Qualified and competent is most important regardless of their title or license

    I want to compliment you on your exceptional insights and wisdom, as you are spot on with this assessment. We come from 27 years of inspecting homes and can always (w/ lots of class room training) uncover work by those seeking to bend corners and take out extra wood for a pipe, regardless of what it supports. Sorry in advance to offend any plumbers out there.

    I am not familiar at all with the Chiltrix system. That said... I have two concerns. One is the same as @EBEBRATT-Ed -- he has a very good point. The other, however, is that it appears to use chilled water as the primary heat transfer cooling medium, and to be using a heat pump for heating. Both of these aspects worry me in New England; unless you have standby electric generation, you stand a very real risk of freezing in the event of a winter power failure. Also, I'd be interested to see just how well it does at design low temperatures. Some heat pumps seem to manage, albeit at somewhat lower efficiencies. Some, however, seem to use electric resistance heating at low temperatures -- with resulting high power costs (and, I might add, demand on that standby electric generator!).

    @Jamie Hall I looked this thing up on line (rather quickly). It looks like a ductless split heat pump. The difference (if I am thinking about this right) is that the indoor unit is basically a fan coil unit and the "line set" carries chilled or hot water instead of refrigerant. So inside the outdoor unit would be a compressor , air cooled condenser, chiller barrel (refrig. to water HX), and a water pump & expansion tank.

    obviously would need to be glycol

    After thinking about I I wouldn't want to open the covers on this one. Could be a little busy inside
