We moved in in July and the house had been empty for some months, we've managed to keep the heating and hot water going but now the pressure is struggling to reach 0.5 bars. We need to increase it (so we've been told) to about 2 bars but we don't know how. It was going upto 1.5 or 2 when we were using hot water or heating now it only goes to 0.5. Please help.

My pressure dropped to 0, when i bled the radiators. There is a solid pipe from the DHW inlet to CH return (called a filling loop), open these valves and the system will re pressurise from the mains. shut valves off when 1 bar is reached. If your boiler is on, it should restart when 1 bar is reached..

hi ,, i just need a bit more detial on your last answer of above question,, you say there should be a silver flexible hose going from your mains cold water to the return pipe on your heating
this has a valve on it ,((((is this valve actually on the silver pipe))) you will need a flat blade screwdriver turn the valve till the pressure reaches 1.5bar then shut the valve off. hope this helps (((also about the bar,,does each little notch ad as a bar or do i take it to the 1 bar simble and a half)))) as there is no diagrame even in my instruction booklet given thank you
