[QUOTE="Rob_the_rich, post: 394752, member: 8419"] We need to know the exact boiler model. For buildings with 2 bathrooms and a cylinder, it is common to replace an existing regular boiler with a combi. the combi can run one bathroom/shower from mains pressure, and the second bathroom can be run from the tank/cylinder. So that both can be run at the same time without loss of pressure. If only one bathroom is used, the cylinder need not be heated. If the boiler breaks down, you still have the immersion as a backup. Makes good sense. [/QUOTE]
