How does the system work?
Apartments in Block 3&4 in Killiney Hill Park are supplied with heating and hot water from a centralised District Heating System. The central boiler plant is fueled by Natural Gas. Hot water from the central plant is pumped around the building as required to supply each apartment with their ability to generate local heating and domestic hot water. Local controls in each apartment enables customers to easily set their time schedules and temperatures to match their own requirements.

Who is responsible for the system?
Hill Park Management Company Ltd (the owner’s management company) are the owners of the community heating system and they contract Kaizen Energy Ltd to manage the system on their behalf. Kaizen Energy Ltd are responsible for operation & maintenance of the main heat system up to your apartment (including boilers, pumps, pipework and meters) that provides the energy you need to generate hot water in your tank and space heating from your radiators. Individual apartment owners are responsible for maintaining and repairing any heating, hot-water and cold water equipment within the apartment including but not limited to the: hot water storage tank, pipework, radiators, taps/showers and controls (programmer, thermostats and motorised valves).

How do I operate the heating system?
The heating system is operable via the controller located on the wall inside your apartment. The operating instructions for this unit should be provided to you by the owner of the apartment or their agent. We recommend that your heating and hot-water are timed on for the periods that you need it in order to minimise your heat bills.

Do I need to program my Hot water?
Yes. You have a hot water storage tank in your hot press that must be preheated in order for you to have hot water. This can be programmed through your controller. You also have the option of using an electric immersion to heat the water however this is ~50% more expensive than using the central system.

How do I control the temperature?
The space heating temperature is controlled via the thermostat located on the wall inside the apartment and you may also have thermostatic valves on your radiators to control local temperatures in each room. The temperature of the water stored in your hot water tank is controlled via the thermostat located on the side of the tank. In order to minimise your heat bills we recommend that the space heating temperature is set as low as you are comfortable with and the hot water storage temperature is set ~ 60ºC (to protect against bacterial growth).

How are meter readings taken?
Meter readings are recorded for individual apartments via a central processing unit located within the central plant of the apartment complex; therefore, access to apartments is not required to take individual meter readings. Readings will be based on actual recordings of units consumed and not on estimated units of energy consumption.

What is involved in the billing process?
Bills will be issued bi-monthly based on your kWh energy consumption and a daily standing charge. Payment terms are 14 days.

What is the standing charge?
The standing charge is similar to the supply charge operated by any utility provider and relates to the basic costs of providing the service regardless of usage.
