do you have a pressure tank as part of your water heater and water pipes? if yes, check to make sure tank pressure matches your incoming water pressure from your municipal hook up

Why the hot water temperature couldn't reach the set temperature (130 degree) in Amtrol WHS80Z indirect water heater?


I have a couple of thoughts. You may have air in the boiler water circuit at the loop that feeds the tank. You'll have to find the vent in the loop to get it out. Second, the automatic valve that opens for hot water may not be opening fully. Have you felt both the boiler water lines that go in and out of the tank? If the water going in is hot and the line out is very cold you have very little boiler water going through the loop. Make sure the isolation valves on the loop are open. Is your boiler full of water? If the boiler loop lines are hot going in and coming out, the tank is full of rust or debris and no water can get to the fins on the internal tubing to pick up heat. If that's the case there is no repair and its time to get a new tank. Hope this helps good luck.

AMTROL Boiler Mate no hot water


You might have bad faucet cartridge or check valve.
Possibly a clogged line.
Contact amtrol info@amtrol.com to hear them suggest calling local technician
Otherwise Amtrol does not post service information or service manuals.
Post question on pro water heater forum to hear them suggest a few things before you call local service technician.

Use search feature on forum above, before calling local service technician
Read suggested answers at fixya before calling local plumber.
Call amtrol and ask why they do not post service manuals or service information when so many promoters are selling the product.

Wh 9L amtrol water heater..the water temp is too hot.. the heater is 10 yrs old is it possible to remove the temp probe and clean?


Amdrol makes indirect-fired water heater that gets heat from a boiler
http://www.amtrol.com/boilermate.htm

1) Pdf manual on amdrol website show a mixing valve that mixes cold water with the hot water so water temperature going to faucet stays the same:
http://www.amtrol.com/pdf/MC10169%20BMconstantempflyer.pdf
You set the temperature of the mixing valve.
You can also set up 2 sets of pipes ... one is connected to mixing valve that goes to sinks and tubs. The other pipe bypasses mixing valve sends hotter water to washing machine.

2) The manual for Amdrol:
http://www.amtrol.com/pdf/9040-586%2001_09%20BoilerMate%20Indirect%20IO.pdf
The new models has a temperature sensor that plugs into digital readout.
This is a thermistor sensor wire that can be ordered as repair part

3) Amdrol has e-mail address:
info@amtrol.com

4) You can post your question on a water heater forum

Beeping noise


E2 means hot water over shot, make sure to check boiler hot water system to make sure zone valve or control is staying closed when the call for boiler hot water to the water heater is isolated. Sometimes a zone valve will fail open or not close properly causing hot boiler water to constantly feed the water heater.

Amtrol water heater WH-7P gets barely warm water


From what you are saying it sounds like an issue with either a circulator pump or a zone valve. It depends on what type of system you have ... if you have a circulator pump that only runs the Amtrol then that is probably bad. If you have a zone valve system then it is probably the zone valve if you still have heat for the rest of the house. If you have no space heating then it is probably the circulator pump.

I have an Amtrol 109 tank on my boiler mounted horizontally (all the literature shows the tank mounted vertically). Lately, the pressure on the boiler slowly bleeds off. I've been told the Amtrol tank may...


If you are losing boiler pressure, it is probably not the expansion tank. Most of the time when these go bad they fill with water and cause a increase in boiler pressure, especially when the boiler is running. If you put a tire gauge on the end of the tank it should read between 10 and 15 psi. If this is the case then the expansion tank is fine. If the tank is fine then you may have a leak somewhere in the system. The perculating that you refer to could also be from the boiler being under filled. Make sure all zones are purged of air and the boiler pressure reads around 12 psi on the gauge. Hope this helps
