LANDLORDS!!
ServicePlus service interval programmers have proved very popular with residential property landlords, ensuring full compliance with the Gas Safety (Installation and Use) Regulations 1998 and with Part L of the Building Regulations. To comply with mandatory annual servicing requirements, the control automatically shuts down the central heating or hot water system once the boiler service period is overdue.
However, a new feature to the programmer permits only partial shutdown of the system, enabling a 15 minute period of water and central heating every hour but never consecutively from one hour to the next.
The installer still has the option to set the Service Plus so that a full shutdown can occur after a 28 day 'service overdue' warning period. But, if programmed on installation, the 15 minute 'On' period option will reduce the effectiveness of the heating system so that it becomes uncomfortable for the occupier without it providing no heat at all.
This should have the effect of encouraging the householder to call the service engineer to check/service the boiler.
