Do you have a separate or built in programmer? if itis separate ISOLATE MAINS undo the screws on the bottom of programmr and checkthat ther are no loose wires ( make a note of where they go for future ref. ). If wires OK check that the valves are working switchoff HW and Heating switch one on at a time and check that each valve is opening and closing and that the boiler and pump fires up ( it could b the micro-switch in the valve is broke! )

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.

No central heating back boiler


back boiler run from a gas fire? check the instructions to operate the gas heat to the back boiler not just the fire
I presume that this a fully pumped system - air lock doubtful There maybe on/off valves on the pipes to and from the back boiler [situate close to cylinder] make sure they are on - anticlockwise turn
or there could be a blockage in the outlet from header tank usually in the loft. or If there is no water in it maybe the mains cold feed it is off.
Note if no water in it DO NOT USE the back boiler

Boiler keeps losing pressure when the heatings off


Hi Leehardcast,

Yes the problems are related. The system is low on water. So now instead of water you have air in radiators which is easily compressed when it heats up. Then pressure loss when it cools down.

Add some water to your system until you have 15lb pressure and bleed out upstairs radiators at the same time.

Please rate this response and Good luck, Phil

Sounds likes you have a hot water system. Some where you have an expanion tank that is full of water and it should be half full. It will a round tank above the boiler and may even have a site glass on the end off it. It will have a special valve on it to lower the water level in the tank. The tank is to absorb the expanding water as it gets hot, and releases it when it cools down therefore preventing your relief valve from popping off.
