I have no hot water and no central heating. I have topped up the water pressure, which was low, but its still not working. I seem to recall that there might be a low pressure switch which needs resetting...

The boiler does not fire when hot water is selected although the red light is on. However the boiler fires ok when central heating is switched on and this does then heat the water. Is the problem in the...


Hi. and you are correct, if the boiler fires when the controller is set for central heating to come on, but does not fire when calling for hot water, the controller is either faulty, or not programmed properly. This is what tells the boiler to do on command, so, this is all that it could be.If you no anything about this controller as far as how it is set up, is it a programmable one, voltage on it, does it have wiring terminals on it that are labeled and can you get to them? If you can, and the wires are labeled, you can jumper them out to see if you can bypass the circuitry and get it to fire up on a call for hot water. This is the way to test it, very easy. You have to look at the wiring schematics to find the wires that are 1-hot and 2- hot water control. Jump across the 2 wires and if it fires, the controller is faulty. Careful if this is a high voltage controller as 120/208/230 volt. Check this out first. It can still be done, you just have to be careful not to ground yourself out. It maybe 24 volts. If it is higher voltage, you can kill power and get a insulated lead/jumper wire with clips on each end. Clip them to the terminals you want to jump out and turn on power. This way you are not touching anything. Please let me know the outcome on this and please when rating me as being helpful to you, be kind. I thank you. I will be here if you have more questions or need my help.

My heat unit will not blow hot air unless we go outside and hit a button on the back bottom of the unit. Once we do that it will blow hot air for that cycle. when it is time for it to come on it is cold...


If it does not have a furnace or heating elements for heating, then it is a heat pump, which is rare for a central AC system, but makes sense of the fact that it blows warm air when you reset the pressure switch, which may indicates freon pressure charge problem if your AC system has a reverse valve and uses freon to for heating (heat Pump).

Do you get heating when outside unit runs? if you do, check freon pressure levels and top up to required pressures. The button you depress is a pressure reset switch ... that is if your AC system is a heat pump ... which, as pointed above, it is not common for central ACs.

Central heating system boiling


more information required but if the boiler supplies the domestic hot water cylinder then the stat on the cylinder may be bringing on the boiler also the boiler stat may be up too high try turning it down.

Bosch greenstar 30 CDi - no central heating or hot water!


it sounds like the system was not cleaned properly when the new boiler was fitted. all new boilers need to have the pipework flushed to remove any debris scale sludge and flux from the system. this is now usually done by a power flush which is basically a big pump mounted on a big bucket and it washes the dirt out of the pipework and collects in the bucket. if this is not done the dirt will block up the small passages in the heat exchanger. i suggest the system is cleaned flush and the heat exchanger changed to help protect the boiler a filter should be fitted (for example a magna clean) if the company who installed the boiler is corgi registered then they are liable for the damages. call corgi for advice.

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.

Amana HTM (heat transfer module) system


I would check the house thermostat(and its wiring to the indoor unit), and if it's OK then check the heat transfer fluid diverter valve inside the indoor unit (should be sending the hot fluid through the big radiator (air exchanger)) until the surface temperature of the radiator is approximately 130 degrees F, then the fan control operates and the fan starts to blow hot air through your ductwork. My HTM is 26 years old and I've had many opportunities to "hone" its operation...
