I justed moved to a flat. The shower was very poor with a pump shower, and noisy. The tank looks very old. I want to change them and get a good shower (more flow/pressure). The old one is vented cylinder. People tell me to change the Megaflow unvented cylinder (125L). One guy mesure the main cold water pressure, it's only 1.2 bar, he think it's not enough for unvented cylinder working. But another guy told me 1bar of pressure is enough for megaflow. Can I change to unvented cylinder? any one in the market can work at 1 bar pressure?
If can't work at this pressure, it mean I have to use vented cylinder + pump? Ohter solution? One guy told me about silent pump, any one use it? it's really silent?
My flat is 1 bedroom flat on the second floor of an old building. I jsut want to have good shower. Welcome for any idea.
