Had this happen to me before, if you have hot water from the boiler going in and out of the boiler mate and the temps are not rising within the hot water means more than likely you may need to remove exchanger and clean sediment off element, basically sediment creates a blanket over the heat source causing poor thermal conductivity. Things to check before removing heat exchanger
- outlet temp of boiler water to aquamate -inlet temp of boiler water to aqua mate= 20-30'F if low then bad thermal transfer or poor water movement
-make sure sensor is reading properly
- get boiler temp higher to speed up thermal gain in water heater
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.
If you check for power at the tank, (the black and white wires) you should read voltage, either 24 vac, or 120 vac, depending on how it is wired. If there is no power there, then you will have to chase power back to where you do have it. There is no fuse or reset button on this model.
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 am not familiar with this brand, but have worked on many others and they share common components. Here's my best guess: There should be two metal covers vertically mounted on the outside of the water heater, one about chest high, the other knee high. Behind each cover is a thermostat with a red reset button in the plate. In most cases, there is a white plastic snap on cover over the thermostat and wiring. Caution, the wiring is hot. Each wire will have 110 volts on it, and can electrocute you. Use insulated tools, and press the resets with the insulated tools, not with your fingers.
Best regards, --W/D--
Most likely either a bad controller (which is the little display you use to reset) or the temperature probe which is accessible on the underside of your tank. Sensor is a 2 wire probe in center of underside and easily replaced.
