Go for the 15-60. After all most houses in the UK use pumps with 15mm ports, even though the pipes are 22mm; and I haven't found any explanation for this.
Hi
No, bought an alpha2 L 15-60 from the local supplier for £88 + vat. Its been fitted today. Same inlet/outlet, direct swap. Looks to be working fine.
Their 25-60 is not quite the right pump. The alpha's modulate flow. I am very happy with the alpha2 L , price was as good as I could find anywhere and I needed it quickly. Its also very energy efficient.
You are showing your lack of knowledge and experience here.
Not everything is as it appears on the internet. Have another read through things and this time read the correct stuff. There is also a simple way to get a 130 to fit as a replacement for a 180. Costs under a fiver
Snb already answered part of it and i never noticed
