If the document is revised or amended, you will be notified by email. The information and best management practices in Chapter 15 provide useful guidance to seal wells that are part of a properly abandoned earth energy system. In many cases, separators are placed between adjacent loops to prevent chafing wear. Source protection plans, which are approved by the Minister of the Environment, must set out policies to address activities that pose a risk to drinking water.

It is an offence under subsection 30 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. Surface water is pumped through the intake waterline out of the river into the vsa pump. The work for the development of this standard will commence late summer and is expected to be completed the spring of In addition to the above requirements in this section, if an earth energy system is cda being used or maintained for future use, then the owner should consider the following actions in this section of the technical bulletin.

For further information about Trades regulation and requirements can be obtained from the Ministry of Training, Colleges and Universities, Sca Branch, at or OCTAA and its regulations establish trades certification and training requirements for persons who work at the construction, alteration and maintenance of certain buildings and building HVAC heating, ventilation, and air conditioning systems, including earth energy systems.

The main drawing shows a DX closed loop system with multiple angled subsurface loops installed in boreholes that were drilled at various angles from one location under the lawn of the home. This Standard will be applicable for new and retrofit installations in industrial, commercial, institutional and residential applications and includes thermal energy storage systems.

The bottom of the vertical waterline is connected to a pump within the supply well below the c4448 level. After the heat transfer takes place, the water csz from the heat pump through the discharge waterline to the river.


A designer can choose to follow the prescriptive requirements of the Building Code Regulation i. All of the drawing show that the refrigerant flowing through the tubing from the ground to the house is at one temperature ground temperature while the refrigerant flowing through the tubing from the house flowing into the ground is a different f448.

The heat transfer fluid circulates back to the heat pump where the heat exchanges between the tube that contains the heat transfer fluid and the tube that contains the refrigerant in the heat pump unit.

Fas amended. Ontario Ministry of the Environment March For more information: CGC certified earth energy systems are thought to represent approximately twenty five percent of the systems being installed in Ontario.

The excavation extends away from the residence into the lawn from the centre and lower left side of the diagram. The refrigerant from the heat pump is circulated through a continuous loop of tubing that extends from the heat pump into the ground. The bottom of the sleeve contains perforations to allow the submersible pump to extract groundwater from the formation through the waterline, towards the heat pump.

Natural gases are found with depth in several parts of Ontario. The second drawing shows a cluster of DX vertical loops installed in a number of vertical bore holes located equidistant along the circumference of a circle around a central point.

The following definitions and clarifications of technical terms in the text of the technical bulletin are provided in this section, and are for the purpose of and use with this document.

Other practical information on cement is found in section 3 of the Provincial Operating Standards, Version 2. Furthermore, surface water bodies, such as a river, pond or lake, generally exhibit less temperature fluctuation than occurs with air temperatures.

This edition introduces requirements for standing column well systems. The void space around the green tubing in the hole has been filled to almost the ground surface with a bentonite css swelling clay product.

Shaping Industry

Before installing an earth energy system in a river or stream valley, a watercourse, a wetland, Great Lakes or a lake shoreline or in hazardous lands within conservation authority jurisdiction, you should check with the local conservation authority to determine if a permit is required under section 28 of the Conservation Authorities Act. A DX system is a type of closed looped system that eliminates the need for an antifreeze mixture heat transfer fluid.


Please first verify your email before subscribing to alerts. Your Alert Profile lists the documents that will be monitored. Capitalized initials used in the text and symbols of this technical bulletin are defined as follows:.

Lawrence River System, connecting channels or to inland lakes, river or stream valleys, including valleylands and watercourses as defined under the Act. For further information about earth energy systems, source water protection and spills the nearest Ministry of the Environment office listed in the blue pages of the telephone directory can be contacted.

Underground thermal energy storage systems formerly, contained within previous editions of this Standard under CSA C Sealing materials and the water that is mixed with those materials must not impair the quality of the groundwater.

This standard is also available to be included in Standards Subscriptions. It supersedes the previous editions published in and under the title, Design and installation of earth energy systems.

A directory of licensed well contractors is available online. The applicable environmental legislation, including the following, should be consulted. For all of these systems, the vertical holes are preferential flow pathways along which fluid and gas may migrate and pose an environmental risk.

Earth energy systems that use vertical or inclined holes can extend deeper than most drilled water wells. General information is also available at the Ministry of the Environment’s Public Information Centre at or In addition to meeting all of the legislative and regulatory requirements outlined in Section 2 the following should be considered to help reduce the risk of leaks, or other releases of these substances:.

As the diagram represents a late fall scenario, the fluid flowing from the residence does not contain heat. Both horizontal tubes will be buried beneath the ground surface to prevent freezing in winter. Persons installing earth energy systems should consult with the Petroleum Resources Centre of the Ministry of Natural Resources located in London, Ontario, telephone: A guide explaining the sewage works process is available at: A Permit To Take Water is generally not required for the operation of a closed loop, DX or BTES earth energy system used to heat or cool an industrial commercial building because, although tubing is installed into the hole or surface water body, no water is being taken.
