hi thanks for your answers.I am at work now so can't confirm make of boiler but yes i do have a water tank upstairs which is always making a noise like it is going to explode but they said it's normal.
.

If the water tank making noise is the hot one, AND the immersion is on 24/7 it may well be the internal thermostat on immersion heater is duff [the one under terminal cover, not readily accessible without tools]

Thus the noise like exploding is the water near boiling, like kettle on hob

If when you turn off the Hot water switch the tanks stops it's noise and water remains hot after few days, then faulty immersion heater thermostat is likely cause

Only cost a few pounds to replace, but as an electrician I can DIY without trouble, your landlord will probably have to pay someone to do it, but that is not your concern

OP, are you saying it's been like this for over a year? Yikes!

Would an easier indication be if the water coming out of the hot tap was extremely hot?
