I have been reading various threads about the pro's and cons of installing vented vs unvented systems, and it seems clear that unvented is the way to go if you have a decent water pressure and flow (>20 l/m).
But what if you don't have decent flow coming through and it is not viable/desirable to install a new supply pipe from the road? Would the next best option be to install a vented cylinder with a pump? I have read about accumulators, but if I don't have the right pressure to start off with then it sounds a bit hit and miss whether it would work.
Assuming noise and space aren't an issue, could you tell me the advantages / disadvantages of installing a vented cylinder and pump set? I am thinking of a water tank in the loft (with byelaw kit) + boiler and cylinder in a shed at side of house. The pump would be something like a stuart turner twin pump to supply the whole house, and WC's would have a direct feed from the loft water tank.
Advantages I can see are lower cost, ability to control water flow, and less annual maintenance for the cylinder (vs an unvented cylinder)
It would be great if this thread didn't turn into a accumulator/thermal store/combi argument, although any relevant comments appreciated.
thanks!
