I'm looking for a pump to boost hy HW pressure and I don't really want to
spend more than £100. These two on ebay look interesting.

One has a pressure vessel and one hasn't. The former is rated at 47ft
(which I guess means 1.5 bar), the latter 1.5-2 bar.

The pump would probably go beneath the floor so size isn't too much of an
issue. Anyone got any experience of either type of pump?
