Megaflow

[vishal]

I have receently put in a potteron conventional boiler (80,000) but the heaters take forever to heat up and the hot water cylinder is too inefficient as it's 20 years old.

I friend recommended upgrading to a megaflow system.

What is a megaflow system?
What are the advantages and disadvantages?
What do I need to change and roughly what are we talking about...hundreds or thousands.

Cheers

Megaflow is an unvented cylinder too complex for diy as you need a licence to work on them or install. You need a quote from a good htg eng (not a plumber)
