YOUR HEATING SYSTEM OUTSIDE THE HOME
The heating for your dwelling is supplied from the Wellheads District Heating Network, which currently supplies heat to the 283 dwellings contained in the four blocks of flats built as part of Aberdeen City Council’s Wellheads Housing Development.
The heat for the Network is generated in the Energy Centre situated on the North East Corner of the development. The heat is produced by a combination of a Gas Combined Heat and Power (CHP) engine and Gas boilers. The CHP Engine uses a gas generator to produce electricity, and the heat from this process is captured, to provide heat and on demand hot water to the properties connected to the heat network, including your home. The electricity produced is exported to the electricity grid. The Gas Boilers provide additional heat for the Network when required.
The heat produced in the Energy centre is circulated through the pipe network to your home as hot water, so there is no gas present in the blocks of flats.
YOUR HEATING SYSTEM INSIDE YOUR HOME
Within your property, your heating system parts are very similar to that of a typical individual gas central heating system, and include the following:
Heat Interface Unit (HIU)
This is the box on the wall, which looks similar to a gas boiler, and is where the heat from the Network is transferred to your home.
Digital Thermostatic Programmer
This is the main control for your heating, and is the small unit fixed to the wall in the hallway. The programmer allows you to set the heating so it automatically heats your home to the temperature you need.
Thermostatic Radiator Valve (TRV)
Allows you to control the temperature in each room, by adjusting the position of the valve between zero and five.
The TRV controls the amount of heat (hot water) that comes into each radiator by sensing the temperature of the air in the room and switches on and off automatically to keep the room temperature constant, based on your setting. Will only work if the main heating system control, the Digital Programmer, is on and asking for heat.
The meter is fitted beneath the flap on the HIU and measures the units of heat used to heat your home. Automated meter readings are taken from each unit, but you can check on your heat usage at any time by reading the heat meter.
