Yes, my project is an edge case. It will be in an unheated solarium, except for the sun and losses from the spa. But it will be used year-round.
Not titanium??? I went with it for my spa project. I had good dealings with Bowman in the UK; it costs far less to phone them than you'd think.
Here's an update. We have the Bowman HX on hand. It took 3X as long to get the check to Toronto as it took to get the HX to Seattle. We'll use a...
So an update... I asked the engineering dean of my alma mater for a referral. She sent me to the retired Chair of the ME department, who turns...
Also: Worrying about that flow rate, I asked EJW about upsizing to the next larger HX. His surprising response was that it would need more than...
Chatted with E.J. Bowman. [Side note: it now costs me 1¢ per minute to call them. I know I'm old, as I recall $5-10/minute!] Their response is...
FWIW: The above Ti line of exchangers seem to be from https://ejbowman.co.uk
That 1.2E6 BTUH/ rating is only when you have the spec's deltaT and flow rate. I found the enclosed spec sheet somewhere on their site. It says:...
Yes, that was obvious, but the HX input temp will vary over time. Not a big deal; we plan to have multiple 1-Wire DS18B20 sensors on the whole...
But that ~26KW available power will be limited by the spa heat exchanger's capacity, and is shared with the floors. One question TBD is: do we...
I'll look at this; I have a longer post to get out today with more questions.
I concur. In my field I see the same issue/outcome. You must be your own champion.
Thank you. We differ on this point. He's already made a major error buying a stainless vs titanium HX. Plus I interceded during the well...
It's not by choice. The 5 GSHP's are already installed and running. (The HVAC contractor seems to be of the 'back of an envelope' MO.) 1 - DHW...
Ahh, I know of such but not the term. Thanks... On the URL you provided, I see they have a newer MF-350PT. I'm looking into its usability for...
