POWERMAX 155 BOILER

[pz865]

I have a powermax 155 boiler and I have removed 2 radiators from upstairs. I have been reading the book on how to refill the system and what is in the book bears no relation to my boiler! As there are no obvious ways to refill the the system I was wondering if anyone out there could help. How do I know when the correct pressure has been reached as there doesn't appear to be a gauge. Further more, the burner light has now gone out and I'm starting to shiver! Could this be due to low system pressure? [email protected][/url][/wiki]

Range or Potterton HE Powermax?
It could be low pressure, the boiler has a cut-out.
There should be a filling loop installed on the system, usually a braided silver-coloured hose about 300mm long.
There should be a pressure gauge on the top left of the boiler control panel.

is there a pressure guage on the front of your powermax 155 ?

What's the serial number?

It dones not seem that she is very interested in getting your help.

This demonstrates just how important it is to ensure that you know how to refill your system before you start draining any part of it.

or even wheather your system is sealed or open vented

Hi there,

There is no pressure guage on the front of the boiler. In fact I can't see one any where on the unit.

Hi there,

The serial number on the top of the boiler is V114791. Sorry for my late reply.

Thanks

It's an open vented model. Check the tanks in the above the boiler normally in the roof space.

Okay, I've checked the tank in the loft above the boiler and it all appears fine. Water isn't frozen, tank all intact, ball cock working as it should. Does an open vented system still need to be manually refilled because I've looked and looked and can't find anything that looks as though it is meant for refilling the system.

Thanks,

What did you shut off to prevent the water from pouring out when you took the rads off?

Hi,

The taps either side of the radiator. Unfortunately one of the taps leaks so i've put the radiator back on as a temporary fit to "catch the drips." The down side obviously is that the system pressure has dropped which has tripped the switch in the boiler and shut it down.
