Is a Combi Suitable for Two Bathrooms?
It depends on simultaneous hot-water demand and available mains water flow. A household using multiple outlets at once may need a different arrangement.
Will a Bigger Combi Improve Water Pressure?
A higher-output combi may provide greater hot-water capacity. It cannot create adequate mains pressure or flow where the incoming supply is insufficient.
Incoming flow and pressure should be checked before a boiler is selected.
