Can anyone recommend a good mixing valve for my hot water system?
I have a Crown Boiler (Cayman 3, CWI103 -
http://www.crownboiler.com/products/res_gas/cayman_prn.asp) that provides
my heat and hot water. Installed is a Honeywell mixing valve (AM-1 Series
1/2" NPT - http://customer.honeywell.com/honeywell/ProductInfo.aspx/AM100-1that
might be it. It's ASSE 1016T & 1017 but there are no other markings).
The water is only hot for the first minute or so and then it's just warm or
luke-warm. That's with the mixing valve set to 4. That should be good for
140 degrees and even if it's a "C" model that should be 120 degrees. The
minimum water temperature on the boiler is set to 170 degrees and the
boiler's thermometer confirms it. I don't know the cold water temperature
orthe mixed water temperature. I might pick up some thermal temperature
indicator strips.
Honeywell's site says it's good for 80 gal. water tanks. My boiler is only
10 gal. and flows at 2.5 gal/min (according to the site).
Maybe I need to restrict the flow rate. I also make sure I turn down the
house's thermostat so that the heater doesn't kick on. The hot water supply
is a lot better in the summer.
Thanks,
Justin
