Legislative Assembly for the ACT: 2009 Week 15 Hansard (10 December) . . Page.. 5811..
(1) What criteria are used to determine whether a solar hot water system is appropriate for installation in an ACT Housing house.
(2) Is a solar hot water system the first option considered.
(3) What criteria are used to determine whether a gas hot water system is appropriate for installation in an ACT Housing house.
(4) If a house is deemed inappropriate for a gas hot water system due to not having gas installed, is there consideration of having gas installed so that water and space heating can also be converted to gas, lowering energy costs for the resident.
(5) Can the Minister provide a table of (a) how many of each type of hot water system has been installed in the last few years, (b) what type of system they replaced and (c) the age of the system.
Ms Burch: The answer to the member's question is as follows:
(1) Housing ACT installs solar hot water units when the property has a peaked roof with one side facing 45 degrees East or West of North and the maximum pipe run (flow and return) must be no more than 30 metres to allow the system to be efficient.
(2) No, if gas is connected to the property a five star gas hot water unit is installed as first preference. Solar hot water units are second preference with heat pump hot water systems the third preference.
(3) The property must be a class 1 dwelling with gas connected or the option of having gas connected.
(4) Yes. Although due to a $51.88 per quarter fixed supply charge ($207.52 per annum) clients may not necessarily save money when gas is connected to their property.
(a) 1 July 2007 - 31 October 2009:
292 Gas Hot Water Systems
90 Solar Hot Water Systems
856 Heat Pump Hot Water Systems
527 Electric Hot Water Systems
(b) The majority of systems replaced were electric resistive, however information concerning the replaced system is not recorded.
