Can a combi boiler be installed in a cupboard under the sink?
In theory a boiler could be installed in a kitchen cupboard, but finding one small enough to fit inside a small cupboard could be difficult. In addition to comply with the latest regulations the cupboard would have to be on an outer wall of the property to enable a flue to be fitted and provide adequate ventilation.
