Net zero is the ultimate goal for housing. ( A home that consumes no more energy than it can produce. ) Net zero does not mean zero co2, however zero co2 emissions from heating and cooling is relatively easy to achieve, for any existing mid and southern Alberta home.
Most of the pollution we emit from our Alberta homes comes from burning 120 or so gigajoules of natural gas. Fortunately, it is well within our capability to get rid of this entirely. The value of a geothermal system is the environmental and economic benefits it can provide, heating and cooling a home for a year using less than 8 gigajoules of energy.
The enormous reservoir of heat from the sun stored deep below the surface of the ground can be tapped into by constructing a vertical heat exchange system that reaches hundreds of feet down into the earth.
The most practical way to deliver this natural heat into a home is by use of a heat pump. The most efficient working source temperature for a heat pump, is within just a few degrees of the desired room temperature, this will deliver the most efficient heating and cooling possible.
A vertical earth exchange loop can obtain a 10 C. + constant working temperature. A vertical earth loop is very different to other earth loop configurations, which typically operate at around 2 C. and lower. The difference between 2 and 10 degrees may seem little until the consideration that a volume of water at 10 C contains five times the heat as the same volume of water, at 2 C. and it follows that delivering heat using the cooler temperature will consume five times the electricity.
The efficiency of a heat pump using a source temperature of 10 c. is extremely high in both heating and cooling modes, it will provide year round comfort and supply winter / summer domestic hot water to the average home, consuming just 6 to 8 Gigajoules of electricity.
We supply residential packages which include a vertical earth loop plumbed into the building, purged and pressurized, ready for inside equipment. These packages come with or without a heat pump, depending on customer preference.
This service is available to HVAC professionals, as well as homeowners and builders, and any home in any location can be retro-fitted with a vertical geothermal system.
Our packages come with full equipment manufacturer warranty, and we provide a 10 year warranty on the earth loop. The earth loop / heat pump package is designed to make the process of Geothermal installation available and affordable to anyone, while ensuring the quality of the earth loop and highest system efficiency is obtained.
