cause

Hi, I'm a landlady and my tenant is worried his Ravenheat combi-boiler will explode because it made strange noises, then steam shot out and water came running down the wall. This same thing happened back in March - so it's happened twice in 5 months. A gas safety registered engineer visited on...

Hi all, when you sense there is only a little gas left in your mapp or propane bottles, is it best to just let the gas burn off, or can this cause light back down the nozzle and cause the cylinder to explode? Or do you just wait until the pressure is low and replace the cylinder? many thanks

Just read installation manual for an electric shower and it says "minimum static pressure 0.5 for flow valve to stay closed" if the pressure was 0.5 bar or below why would this cause the flow valve to open? Thank you.
