replace storage water heater with megaflo (discharge pipe Q)

[Narak]

Hi Guys,

I'm a bit of a novice when it comes to plumbing, but I'm trying here, so please bear with me.

I'm trying to get my old unvented storage water heater (direct) replaced. I've heard only good things about megaflo.

Given that my discharge pipe is horizontal, and I'm not 100% sure where it goes (I live in an apartment block), is it possible to have some sort of set up to allow me to have a megaflo installed?

I've read that the discharge pipe has to be of a certain length before the tundish, and a certain length after, based on the diameter of the pipe, and the restance etc. (this bit baffled me a bit).

Does anyone have a solution? Here's some pics of my current setup.

Also, if it's a lot easier to just get an updated version of the one I already have, could you guys recommend a good company to go with?

Range Tribune do some good ones, but the setup needed would be the same as the megaflo (tundish and all). Does anyone know any that aren't as complicated?

Cheers
