Replacing Baxi Solo 2 with Combi via npower or northern gas?

[mateus]

Hi,
Can anyone give any suggestions on how much more efficient say a
Glow Worm Ultracom 30kw sxi or Potterton Promax 24 HE Plus would be over an old Baxi Solo 2 50RS??

From looking at various websites it looks like the Baxi is/was 70% and the newer 2 are 90%?

Thinking of getting a combi installed by npower/northern gas or someone else - any experience of how good these companies are??
Was thinking it would be in region of £2k-2.5k is that about right?

Thanks for any advice

Get a quote from an independant installer and I would expect them to be considerably cheaper.

Problem is who can you trust?
At least with a big company you can usual get any problems sorted?
Smaller one man firms can just dissapear after doing the work - good job or not!

Seen lots of Northern Gas installs...........hmmm. Depends on who your fitter is....some good, some not so.

Thats the idea i got from some mixed reviews on tinternet - not much about npower though?

Id avoid the potty promax like the plague, every one ive seen has had multiple problems

I,ll second that. Anyway whats wrong with yer Solo 2,why do you want a Combi

The main hot water cylinder has quite a lot of corrosion around it - been leaking for years before we moved in. (cost to replace according to 3 quotes is £1000+)
Also the water never seems to get really hot - or takes an age due to tank size.

So was thinking rather than spending on new/smaller tank to get combi and get hot water too, maybe save a little on the gas too??

The boiler seems to be running ok at present - fingers crossed!

F*** me i'd come from southampton, change the cylinder and still only charge you 2/3rd's of that!!

lol!

All i need is someone a bit closer then!

Even with larger companies the installation is only as good as he engineers that fits it. My advice would be to ask around for recommendations for installers in your area.

i think the promax is quite a decent boiler

I'm trying to find some decent ones - but not having much luck!

Mark Br is right, take his advice, also ask for a boiler with a three/five year warrentee, and one that has weather compensation built in.

Just got first quote - Veismann 35kw - £3080 (includes 2 replacement rads - approx £200)
Is this about right??
Seems top end - was thinking nearer £2k ??
