NEW COMPLETE SYSTEM INSTALLATIONS:

 When carrying out a completely new heating system installation in a new build

property or a first time installation in an existing property, then the heating system must conform to current building regulations Part
L1a. All new domestic heating systems must have a minimum of two heating zones. Each of these zones should be controlled by a
thermostat and zone valve. Alternatively individual electronically controlled Thermostatic Radiator Valves may be fitted. If domestic
hot water is provided by a storage system then the storage system or cylinder will require separate time and temperature control.

All radiators must have TRV's fitted in all rooms except bathrooms and any rooms where a thermostat is located. The exception to this
are single storey, open plan dwellings where the living area is more than 70% of the total usable floor area. Then this type of dwelling
can be controlled as one zone.

EXISTING INSTALLATIONS:

 When carrying out boiler replacements on an existing system, the regulations do not require separate

zoning of the upstairs and downstairs and compliance with the regulations can be achieved by a single room thermostat or
programmable room thermostat. It is however recommended that 

TRV's

 are fitted to all rooms except the bathrooms and the room

where a thermostat is located.

The appliance must be installed in accordance with, and comply to, the current: IEE Regulations, Building Regulations, Building
Standards (Scotland) (Consolidation), Building Regulations (Northern Ireland), local water by-laws, Health & Safety Document
635 (The Electricity at Work Regulations 1989) and any other local requirements.
