Baxi Megaflo Vs Baxi Ecoblue?

[ChrisPlumb]

Hi Guys,

Making a choice between buying Baxi Megaflow 32KW System or Baxi EcoBlue 32KW System.

Will be supplying Megaflo 210L cylinder.

Baxi themselves don't seem to be able to give any answer on the differences other than one has an LCD screen, the other is just LED screen with turn knobs.

What would you experts recommend or advise? Not looking for persuasion on other brand as can get discount on Baxi. What's the difference!

Thanks in advance.

How many rads is the boiler feeding?

Either will do the job fine Chris the megaflow 32kw has the stainless steel heat exchanger and the eco blue 32kw is the next generation of boilers with the aluminium heat exchanger I fitted both and as I said each will do the job. Kop

I haven't installed many baxi's, but their website claims the mega flow system boiler is perfect for households with high hot water usage. Do you know why they would claim that?

16 Rads in total

That’s brilliant, thanks for help... would you have a preference over the two on which was “better”.
The EcoBlue looks cheaper in its design but also a more newer model with its LCD display which reviews advise difficult to use and fault find.
Mega flow appears to have been around longer and originally built to accompany “megaflo” type cylinders.

Tech data looks near comparible across the two which isn’t helpful and response from Baxi no help.

Stainless steel or aluminium HX... would you have a preference over the two?

Appreciate advise thank you

Boilers way oversized

Boilers way oversized

Many of rads are doubles and quite a few double tall radiators with high output.
Also want to ensure quick heat recovery in the cylinder when CH turned on?
Any issues with a oversized boiler.
Surely better for future proofing and ensuring max outputs achieved on rads?

Yes but unless it’s correctly set up you’ll never get the proper efficiency benefits of condensing

I maybe jumped to conclusions while replying to that, and without knowing the size of the radiators in the system that was a little stupid of me so I apologise.

I will give you an example though. We've just finished a new build which has a 210ltr unvented cylinder, around 90 - 100 sqm of underfloor heating and 13 radiators upstairs. This system is ran of a 24kw ecoblue and the system runs sweet and has room for expansion in the future if necessary. I recommend you get your system sized correctly before you spend excess money on a boiler you don't need.

No problem, thanks anyway very helpful. The previous was a 28kw and have now added 2 bedrooms and 2 bathrooms so working on a considerable increase hence the 32kw selection. Will work out all outputs of rads and get it sized correctly.
Many thanks

Baxi megaflow 32kw would be a good choice I like the stainless heat exchangers this boiler was designed to supply the primary heated water for a megaflow cylinder and heat for the radiators . Kop

Decided on the Megaflo based on your two replies… Thanks very much king of pipes.
Reading about some of the issues with aluminium heat exchangers against stainless steel, its a no brainer (to me anyway).
Also the megaflo being primarily designed for unvented cylinders when they started to become popular etc.

Cheers

Ensure the system is thoroughly cleaned and a mag filter fitted you have made a good choice. regards kop
