Earth energy systems that ccsa identified in the local assessment report as posing a significant threat to water quality or quantity may be subject to policies to manage the threat or that prohibit the earth energy system from being located in a particular area. To reduce corrosion and increase lubrication, additives such as corrosion inhibitors or mineral oils are added to the heat transfer fluid.
Legislation and regulations change from time to time so it is essential that the most current versions be used. Earth Energy Systems – Legislative Overview 2 This section outlines the current pertinent legislative and regulatory framework in place to protect the environment and human health, and to address safety during the installation and use of earth energy system technology.
An ATES system largely uses groundwater as the heat transfer fluid. Certain installation and maintenance work pertaining to or associated with earth energy systems may be subject to additional legislative and regulatory controls.
Does not apply for individual household Applies and Must be Obtained Before Installation for all other cases. Site conditions and system design should be carefully considered when choosing a sealant. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the dsa explanatory or informative material.
C448 Geothermal Heat Pumps: Bi-National American–Canadian Standard
There are three basic types of outside loops for earth energy systems. All figures in this technical bulletin are not to scale and are for illustrative purposes only. Parks Canada should also be contacted if the project is located within its jurisdiction including the Trent Severn Waterway and the Rideau Canal.
For the design of a surface water or submerged closed loop system, the standards Section 6. An example of not meeting the purpose of the Act could be the taking interferes with another person’s well. There are potential environmental risks associated with earth energy systems. The diagram depicts a summer setting and represents heat taken from the residence into the water in the heat pump to cool the xsa. Figure 9 shows an example cza two tubes extending out to a single coiled unit in the water.
Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. This standard is also available to be included in Standards Subscriptions.
If the document is revised or amended, you will be notified by email. Commonly used refrigerants and banned refrigerants are discussed in sections 2. You may delete a document from your Alert Profile at any time.
CSA Group will manage the standards development process through the establishment of a Technical Committee that will have full responsibility for the content development of the standard. Heat from inside the building is extracted sca the building’s heating or cooling circuit. Under this legislation, local source protection committees have completed science based assessment reports identifying areas where sources of drinking water are most vulnerable, and the activities that have the highest potential to impair the quality or quantity of these drinking water sources.
It is an offence under subsection c4448 1 of the Ontario Water Resources Act for a person to cause or permit the discharge of any material of any kind into the natural environment that may impair the quality of any waters.

Standing column well components and heat transfer processes. The diagram uses a blue colour on the right side of the vertical U loops and the other horizontal tube in the ground to the heat pump in the residence. Water is moved from the heat pump through the second waterline and discharged in the upper portion of the well below the water table. Artesian flow of water onto the ground surface is difficult to control and can result when zones where groundwater is under pressure are c48 in overburden or bedrock formations.
Groundwater examples include the following:.
Table 1 is a three part table designed to provide Ontario’s Environmental legislative framework for earth energy system outside heat exchange loops. Two waterlines extend from the heat pump into the excavation. Earth Energy Systems in Ontario.
CAN/CSA-C Series (R) | Standards Council of Canada – Conseil canadien des normes
The bentonite forms a seal to prevent the hole from acting as a pathway for contaminants. There is an excavation in front of the house that exposes a heat pump attached to the basement of the house. Circumstances where a person could take more than 50, litres of water or cause interference with any private or public interest in the water include:. These systems are sometimes called submerged closed loop earth energy systems.
There are a number of related standards, guidelines and best practices available but stakeholders have identified the need for standardization through a neutral third party accredited process for the design and installation of geothermal heat pump systems as a priority.
To reduce the risk of oil, mineralized water or flowing groundwater problems, an owner should retain a professional engineer or professional geoscientist experienced in hydrogeology, earth energy systems and, where warranted, petroleum resources before proceeding with the decommissioning of an earth energy system. The schematic traces the movement of heat as follows:.
When constructing an open loop or aquifer thermal cea storage ATES system with vertical holes, the person constructing the hole should consider the following:. Below a certain depth, ground temperature is relatively constant all year long. The work for the development of this standard will commence late c4448 and is expected to be completed the spring of This standard is not included in any packages. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.
Generally, the outside loops for a closed loop system are installed in one of two configurations: Earth Energy Systems and How They Work 1 Earth energy comes mainly from absorbed solar energy and conducted heat c484 the earth’s molten interior, both stored in the overburden, rock and water of the earth.
