How to decide which boiler to buy

[Blue Nose]

Is anyone able to advise me on which of the following tboilers to buy? Listed
from cheapest to most expensive.

1) a Baxi Potterton Assure 25
2)a Baxi Potterton Assure 30

What are the differences between the two?

3) a Worcester Greenstar 25 HE boiler (10 year warranty)
4) a Worcester Greenstar 30 HE boiler (10 year warrenty)

What are the differences between the two?

Which is the most energy efficient?. Is anyone able to direct me to a source that will help me decide which to buy?

Thanks folks.

The plumber pros on here rate intergas boilers highly -you could put one of those on your shortlist.

And they dont like Worcester!

I like my Johnson and Starley boiler. Low cost, reliable and seems to be very efficient.

Many other makes are available.

The J&S boilers are re-badged.

The J&S boilers are re-badged

So who does make them ?

I forget now, n J&S as they do not have the manufacturing capacity or capability to make boilers. J&S specialise in forced air.
