Central Heating - Lack of hot water

[harry1234]

Any suggestions on what could be wrong with my central heating. A leaking raditor ws replaced with a new one, working perfectly - hot. Since this raditor has been replaced my hot water is not as hot as it was, i.e. not enough to fill a bath, the hot water runs out once 1/3 is filled. Everything appears to working correctly, just lack of hot water, before it was hot and always enought water. Any advice?

It could be the heating coil in the cylinder is not vented properly causing the water in it to flow slowly. Look for an air vent at the cylinder to let out air when the boiler is off. Failing that, switch on only the hotwater to clear the air by switching on and off several times or call back the installer. Check the cylinder thermostat is set at around 60C.

Thank you Stanley man, I forgot to mention that the tank which holds the water is hot at the top and cold at the bottom when you fellthe outside of it -

It is obviously not heating properly as mentioned before. Check that the timer has not been altered, it's sometimes the simple things that get missed.
