fitting a whole house water pump

[Crock]

Hi.

owing to the fact our hot water pressure is rubbish, I have just purchased a pump (salamandar 2bar hot water only).
However, after reading the blogs on the screwfix site, it appears there is more to fitting these than meets the eye.
has anyone out there fitted one? if so can you explain how to fit it? (does it matter where in the hot water system you site it?)

thanks

Site it neat to the cylinder with good access for future repair.

follow the destructions with the pump.
