Question about mega flow

[vipin]

Hi, I hope someone will be kind enough to enlighten me on Mega flow. At present I have standard central heating system with a potterton boiler, with a hot water tank in the loft. I am considering Mega flow but have a question.
Do the central heating pipes need to be changed to 22mm?.

Hope someone can guide me on this.

a hot water tank in the loft.

Really!

I am considering Mega flow

Why?

Do the central heating pipes need to be changed to 22mm?.

I would imagine they're already 22 or 28mm flow and returns. These would need to go to the megaflo.

A Megaflow has to be installed by someone qualified in accordance with G3.

Your chosen installer will be able to advise you.
