I am buying a wood pellet boiler and want to have mains pressure hot
water. I have been told that with type of boiler you need a buffer
tank so that the boiler will not cycle.

Wood burners do not run at a constant temperature and cannot be
turned off in an instant like a gas boiler, thus there needs to be
something able to absorb the variable heat it produces. It is gas
and oil boilers that cycle and this is a problem as it wears the
boiler out more quickly.

I am also putting in
underfloor heating and solar panels.

A heat bank is ideal for this application. It will absorb the heat
from the wood burner and solar panels, which it will convert into
instant hot water at mains pressure and water at the best
temperature for underfloor heating. It will also provide water at
the best temperature for radiators if you have any rooms where
underfloor heating is not the best option.
