The Honeywell AM-1 series accurately adjusts, maintains and limits the hot water temperature to a desired setting selected by the user. In domestic water applications it offers scalding protection and bacteria growth control. By installing a Honeywell AM-1 mixing valve and raising water heater storage temperature setting and limiting mixed outlet water temperature to safe temperature more usable hot water is available. In heating applications it provides comfort and protects the equipment.

Honeywell-Sparco AM-1
About eight years ago I installed an AM-1 mixing valve in my home's radiant floor heating system (after a competitive valve's failure), and it has worked flawlessly since then, holds temperature well. Also installed one in my daughter's system five years ago with the same result. Excellent product, highly recommended.

Item sent not the same as the item shown
Just a heads up, the item that they shipped is not the same as the item pictured, the flanges are different, they're larger. The item shipped is even different than what's on the manufacturers website. See attached photo.

Worked exactly as specified
Used it as a diverter on return of 2 zone radiant slab with air source hydronic heat pump with 50 gallon buffer tank. Previously would over run for a day overheating slab then cool for a day. Now can set slab temperature and heating is very steady, with heat pump cycling once an hour or so depending on heat load. This works great even with a few degree temp differences

boiler helps heat pump
I intentionally undersized an GSHP that heats a radiant floor. This mixing valve now keeps the primary side of a flat-plate heat exchanger at about 105 deg so the floor side will not fall below that. On very cold days when the heat pump is too small to maintain the normally supplied 110 the valve adds enough heat and still allows the heat pump to be the main source of heating to save oil.

Valve wouldn't make name plate.
My HVAC contractor installed one of these valves on a zone that needed the published 180 degree temperature. The valve would only supply about 140 degree water. He swapped out with ANOTHER new valve. Same model - same result. To get the required 180 degree water, he finally had to swap over one of the existing valves, and put the new, under-performing valve on a less demanding zone. These valves are fine if you need only 140 degree water. They apparently cannot supply the published water temperature.

Q: Can this valve be installed with the inputs aligned on either a horizontal or vertical axis? Does it matter, or can it be installed either way?

Q: do you pull up on it or do you push down on it to turn up the heat thank you

Q: I have one of these feeding a radiant floor loop - but despite having primary loop temp of 170 or so, the most this seems to kick out is about 100. However, I am speculating that my flow rate is not adequate (1 3/8" pex loop). I don't know what that flow rate is. I have two other valves on air handlers where they appear to work just fine.

Joe: We had a similar problem, check the following: 1. Look for obstructions, debris in the line. The opening is extremely small in the valve. Almost anything can clog it, reducing flow and loop temp. 2. Do you have a leak somewhere down line? Are you making up water? 3. Do you have a Y-strainer, is it clean. Do not rely on just opening up the drain on the bottom, the screen could be clogged and not allow flow past. Hope this helps. Tim

Hi, It is very possible that the flow rate is too small to adequately mix and control the temperature, also usually there is a possibility that the internal cartridge may not be good any longer.

Q: Would this work for DHW or is it just used for radiant flooring? If not what's the difference between the valves for DHW and radiant mixing valves? Thank you
Asked by salv 13 years ago

Verified Reply- PexSupply StaffMixing valves that are designed for heating systems generally have higher temperature ranges than ones designed for domestic hot water plumbing. Since heating mixing valves also do not carry the necessary approval codes for use with potable water, we would not recommend using them in such applications.
