Will increasing the pressure on a condensing boiler give an increase in output temperature at the radiators?

My Vaillant condensing boiler manual says the pressure should be between 1 and 1.5 bar but my gauge is reading .75 bar. However, I can only turn one of the filling loop valves on - the one at the pressure relief valve. Will increasing the pressure give an increase in output temperature at the...

I am at work now and so can't look at the boiler. The valve handles are just a bit of plastic pressed onto a pin with two flats and in good condition. I suppose I could take that off and use a small shifting spanner? The valve handles are long triangular in shape so are they shut when this long...

I have a Vaillant ecoMAX 828/2E condensing boiler. The pressure gauge at the boiler is .75 bar and I want to increase it to 1-1.5 per the manual. The reason I noticed the low pressure was I turned the heating up at the boiler with no change in heat at the radiators. There is a built in...
