Heating system

[Mr. Escort]

Darren, I would recommend that you get a Plumber in to do a full power flush on the system, as you know that used to be my job in the Uk for the last 24 yrs. If you do it yourself and you have a problem you will probably struggle to fix it, you could blow a joint as its under alot of pressure.
The Glowworm Ultimate is a good boiler with a cast iron heat exchanger so you shouldnt have a problem there.
The chemicals are all much a muchness....sentinal is the cheapest, it will take about 6 hrs to do it propery and make sure they flush one rad at a time not all of them togeather...

dont let him sell you a new boiler.

The heating has struggeld through the winter. I want to change the pump as it sounds like it is straining a bit.

Are these screws isolators so I can shut off the water and just un screw or is it alot more complicated than that



Many thanks, Darren.

yes the screws are isolaters turn then 1/4 turn so they are at 90 degrees to pipe but you might find they don't want to turn and if they do they might leek abit they can be sh#te but you won't know until you try.
If they turn then it is just a question of unscrewing the big brass nuts that connect to the pump and change.
If you system is quite big or you have lots of drops to down stairs rads then i would put a 15/60 pump in it has abit more grunt than the 15/50 you have now, good luck

Dont forget the arrow on side off pump make sure you make a note off which way its facing, and fit pump the same way if valves fail you could bung the f&e tank in loft, saves draining system tho also have some spare towels available to wrap under pump

[ModenaRS2]

Thats great, thanks very much. I will get a 15/50 and do it before the new flooring goes in.

I will make sure it goes back as per the photo.

Top tip, cheers.

[Mr. Escort]

Or you could move out here where you dont need heating

[ModenaRS2]

Would love to Wayne but I love this damp, rubbish cold weather too much

I ment 15/60 loads of rads, drop, twist and turns.


Cheers

Darren, your better off draining the system down before you attempt to put a screwdriver to isolate those pump valves...there bown to leak mate then you will have a problem on your hands..

I guess the pump is upstairs in the airing cupboard....jump up into the loft and tie up the ball valve in the small header tank and then go to the boiler and hopefully you find a drain off point on the pipe work above it...put a hose pipe on it and open the drain point with a small adjustable to drain the water down, if there isnt a drain point on the boiler there should be one on a rad... then disconnect the pump and change..

Then refill the system by jumping back up in the loft and open the ball valve up, you may need to bleed the upstairs rad...

Also change the pump valves as well to gate valve type....

[marky4]

any luck ????

[ModenaRS2]

Not attempted it yet.

I have bought the valve and the room it is in is my downstairs utility room.

I have stripped the room ready for decorating so will try and fit it next weekend.

I would have done it this weekend but the weather is soooooooooooo nice I spent all day yesterday in my new RS

Today will be the same
