What is the warranty period on these boilers?

I want a boiler where I don't even need to know such things. Even if
they come and fix it for free afterwards, I still don't want a boiler
that fails and leaves me in the lurch.

So long as you do read up on the brand reputations and don't buy on
the basis of sticker price alone, you can get a reliable boiler
without spending excessively.
