Potterton Netaheat Electronic 16/22

[TomP]

Boiler is just under 20 years old. In the last 3 or 4 years have had fan and PCB replaced.

The boiler itself is now getting noisier, banging noises for about first 10-15 minutes after firing up. then it quietens down. Reading advice, suggests it may need de-scale, especially as we live in a hard water area.

Any thoughts on:

Is it worth doing this on a boiler 20 year old?
What is best product to use for de-scale?...I've been reading about Sentinel X200 noise reducer which remains in the system.
Is this likely to be the cause of a VERY hot boiler casing (bottom half especially)?

Many thanks.

time to change the boiler mate. parts are getting sparse and there are safety issues with this boiler. when was it last serviced and have you got a co detector.

X200 wouldn't do any harm.
System probably getting sludgy, a flush would help.
The pump may be getting blocked or tired.
The boilers have asbestos panels which drop down, and some parts are obsolete. If the case rusts, which happens, they're killers.

I've been meaning to retire mine for the last 2 summers.

cant take yer work home though eh

Thanks for replies.

Last serviced abot 2-3 years ago. Noise sounds like it's coming from the bolier (thupin/canking every 20-30 secs for about 10 mins).

Anyone recommend someone to replace the bolier from my area (Basingstoke, Hants)?...hope to leave till spring. British Gas quoted 3.5K which seems a bit excessive.

Mine was replaced with a Potterton Profile e60. Was almost a straight change, only the hole for the vent needed to be made round as the Netaheat was square.

Please excuse my ignornace, but presumably a Potterton Profile e60 is one of the new type of condensing boilers? In replacement for my Netaheat, I would have to have a condensing boiler now wouldn't I?

When Mr. British Gas gave me the quote for £3.5K he said I would have to change to a 22mm supply which would have to be routed round the outside of the house and in through the back of the kitchen. I'm keen to have as less upheaval as possible, so perhaps a Potterton Profile e60 may avoid all this?

 

[gavinda]

hope that profile wasnt fitted lately as its not a condensor and has been out of production for at least 5-6 years i reckon.

op if you're on a 15mm gas supply then yes the supply will need enlarging
