The diagram uses a blue colour on one horizontal tube from the residence and the right side of the horizontal U loop tubes in the ground to represent the heat transfer fluid flowing from the cwa pump in the residence.
Subscription pricing is determined by: This new legislation c4448 help to reduce the risks associated with encountering hazardous gas while drilling and constructing these types of earth energy systems. To help protect waters from discharges that may cause impairment, the Ministry of the Environment administers and enforces a sewage works environmental compliance approval program.
The reverse occurs during summer. An example of not meeting the purpose of the Act could be sca taking interferes with another person’s well. The regulated areas include hazardous lands such as unstable soils Leda clay, organic soils and unstable bedrock karstwetlands, areas adjacent to wetlands, shorelines and areas susceptible to flooding and associated allowances, i.
Notes accompanying clauses do not include requirements or alternative requirements; caa purpose of a note accompanying a clause is to separate from the text explanatory or informative material. An Energy Centre with short term thermal storage in tanks.
For the purposes of this technical bulletin, a ground source heat pump means the same thing as an earth energy system. Because of the environmental concern over methanol, the Ground Source Heat Pumps Regulation bans the use of methanol as a heat transfer fluid in new closed looped earth energy systems and those that were constructed, altered, extended or replaced after June 1, Ground source energy is designated under O.
Figure 4 shows tubing placed in a vertical hole that is part of a closed loop earth energy system. The heat transfer fluid does not flow into or mix with the surrounding rock, soil or groundwater in the borehole.
Any reference in this technical bulletin to an environmental compliance approval includes a certificate of approval or provisional certificate of approval issued under section 9 or 39 of the Environmental Protection Act before October 31, and an approval granted under section 53 of the Ontario Water Resources Act before October 31, Green tubing in the trench will be used to carry csz heat transfer fluid.
Under Section 28 of the Conservation Authorities Actconservation authorities also regulate activities that may change or interfere in any way with the existing channel of a watercourse or change or interfere in any way with a wetland. The retained professional engineer or professional geoscientist should, csq necessary, determine the type of drilling fluids with additives that need to be used during the re-drilling of the tubing to counterbalance formation pressure to prevent water from entering the hole prematurely.
We have no c448 or corrections for this standard. Persons designing earth energy systems should study:. This consolidated version of the C Xsa standard was reprinted in October to incorporate the update 2 dated October ca the original standard. Detailed documentation of the original installation is helpful in determining the best course of action to properly decommission an earth energy system including removing cssa heat transfer fluid and plugging the earth energy system.

x448 A designer can choose to follow the prescriptive requirements of the Building Code Regulation i. 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. Placement of a sealing material in the entire void space in the hole at the time of initial construction can also help the owner significantly reduce the cost of properly sealing the hole at the time of decommissioning i.
The bentonite forms a seal to prevent the hole from acting as a pathway for contaminants. Other circuits have two tubes that extend to a single modular csx tubing unit in the surface water See Figure 9. You may delete a document from your Alert Profile at any time. For further information about skilled trades, the Ontario College of Trades and the Ontario College of Trades and Apprenticeship Act,please refer to the website.
The blue coloured tubing represents the heat has been transferred by conduction csw the subsurface and is circulating back to the heat pump. There are two common types of thermal energy storage systems in Ontario: As the voice of the U. Visit Ministry of the Environment’s website. Proceed to Checkout Continue Shopping. The discharge well is represented as a vertical hole extending from the ground c48 into the ground.
Standards Council of Canada
The Building Code Regulation requires the construction or renovation of an earth energy system to conform to one of the following standards published by the Canadian Standards Association:. Need more than one copy? Figure 10 is a collection of three drawings showing directional, vertical and horizontal arrays of tubing loop arrays for a direct expansion geothermal system. In some scenarios, work permits and tenure are not required for activities that may be associated with the installation of an c44 energy system.
Already Subscribed to this document. This technical bulletin provides an overview c484 Ontario’s environmental legislative framework governing the outside loop components of an earth energy system. This edition introduces requirements for standing column well systems.

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.
An ATES system largely uses groundwater as the heat transfer fluid. C Geothermal Heat Pumps: Arrows show groundwater is pumped out of the supply well through the waterline into ccsa heat pump in the excavation located in front of the home.
The values given in the parentheses are for information only. Below a certain depth, ground temperature is relatively constant all year long.
