Which one should I go for?
The current condensor boiler and cylinder are sighted in the garage.

Atmos Multi 24/80+
The best of both worlds.

The Atmos looks interesting.
Would you say this brings much benefit over a megaflow apart from the central heating side of things.
I am due to move house soon and will possibly be having up to 3 showers. We currently have two showers powered by a Worcester Bosch Highflow Combi which just about works with 2 showers but isn't great, so I Know I need to go down a different route.
Do these Megaflow/Atmos Multi Boilers really power 3 showers at the same time without any noticeable difference.
I'd love to be able to have 2 (occasionally 3) showers that could be on at the same time but thinking this might be un-realistic.
Thinking of using something like a 200mm Rainshower or similar.
Appreciate the advice as most people I know just have combi's and aren't that interested in this type of system.
Cheers

The Ethos looks very good and cost effective too. It can have a secondary DHW circulation kit added giving instant DHW at the taps. It has a very high flowrate.
At 23 litres/min DHW, that is about 6.5 litres/min to three showers and then cold added taking it over 6.5 to a decent shower rate. Obviously more flow with only two showers and bang on with one - similar with any mains pressure system. Have mixers with pressure equalisation valves in them.
The Ethos outperforms the W-B Highflow.
How about two suitable combis. Have one do upstairs CH and one down. Zoned so cheaper to run as upstairs can be off all day. The two combis will do the showers OK.
Look at this thread.

Avoid an unvented cylinder. An unnecessary expense, and potential bomb requiring an annual service, when excellent quality combis are around.

Thanks for the reply. Sorry to ask a stupid question but what is a secondary DHW circulation kit?
I did think about having two combi's but hadn't seen much on it. Obvioulsy haven't looked hard enough.
I'll have a read through the thread and no doubt come back with even more questions
Appreciate the help.

The DHW draw-off pipe that the hot taps are off loops back to the combi (or cylinder) and is permanently heated and lagged. DHW is available in 2 secs at the taps and no cold dead-legs.
Thanks for the advice DD. So do you think that the Ethos would power 2-3 showers just as well as a Megaflow or the Atmos then.
Or would you need two Ethos Combi's to do this?
Cheers again
