The home of Don & Marilyn Ambrose is a 2200 sq. ft. home located close to Orillia. The heating & air conditioning costs for this home are just over $ 500 a year.
The 4.5 Ton Polar Bear Water Source Heat Pump System derives almost 70% of its heat output from a "Vertical Closed Loop", basically located in and around the rock garden in the forefront of the picture.
This particular system is comprised up of 9 vertical drilled bore holes 90 feet deep, each hole 10 ft. from the other. Two plastic pipes made of H.D.P.E. with U-bends filled with a 25% ethanol water solution are in each hole and then connected via a header system to the Polar Bear Heat Pump.
Typically, vertically bored hole systems require 180 ft. of bore hole and 360 feet of pipe per ton of equipment on a properly sized installation.
The Heat Pump through the loop system is either absorbing heat from the vertical earth loop network or discharging heat in Air Conditioning mode, the reverse of heating.
The Ambrose's basement was done in ceramic, utilizing the "Domestic Hot Water Option", infloor heating tubing was installed for added comfort. Back-up "Duct Heater" heat is installed, but set at 50F. as in all Polar Bear installations.

Bill & Carol Gregg's 3800 sq. ft. home, 6000 sq. ft. in total space, heated at 72F. for just over $ 800 this last winter. Although "catastrophic back-up duct heaters" were installed, not once, not even with the wind chill at - 43C. did they ever come on to help heat the home.
Their 6 Ton Polar Bear Water Source Heat Pump absorbs its free energy from a "Horizontal Closed Loop". These systems are trenched in with a back-hoe, pipes are laid on either side of the trench, and a 25% solution of ethanol and water is pumped continuously around the circuit when the thermostat calls. On the heating cycle, the solution absorbs heat from the ground and the heat pump removes it as it discharges warm air into the home.
The reverse happens in air conditioning mode, the unit removes the heat from the home and the loop system discharges this heat back to the earth. On average, a minimum of 500 feet of 1inch H.D.P.E. plastic pipe is laid per Ton of Heat Pump installed.
Mr. Gregg before he made his decision to purchase from Polar Bear was concerned about reliability, service costs and longevity. In answer to Mr. Gregg's concern, Polar Bear Water Source Heat Pump Mfg. Design centers on SIMPLICITY.
First, all Polar Bear units are manufactured with Scroll Compressors that operate 18% more efficiently then Piston compressors. Scroll compressors, with only 6 moving parts as opposed to 20 or more in a piston unit, installed in a heat pump which has been properly sized to the heat loss of that home, will last up to and or exceed 25 years.

Mr. & Mrs. Bakers' 3000 sq. ft. bungalow with a full walkout basement is located near Huntsville. It has a 5.5 Ton Polar Bear Water Source Heat Pump located in the basement attached to normal ductwork. This installation utilizes the heat energy in the Water from their drilled water well.
Nearly 70% of the heating energy comes directly from the water for FREE.
The thermostat calls for heating, a valve opens, 7 to 8 gpm of water flows at 46 F. (8C.) through the Heat Pump. The Heat Pump drops the water temperature roughly 10F. or 6C. by extracting heat from it as the it passes through the unit.
To do this requires some electrical energy to power a "Compressor Motor", "Fan Motor", and "Water Pumps", which themselves produce the remaining 30% of the Heat Output. The "Electrical Cost" is the only operating cost to the homeowner which in almost all cases is less costly then High efficiency Natural Gas.
The electrical energy costs are tallied with the help of an "Hour Meter", permanently installed on all Polar Bear units. Open Loop Systems require approximately 10 Imp. Gallons of flow per minute while operating. The water leaving the unit is then discharged to a leaching trench, pond, or secondary return well.
Mr. Baker has been extremely pleased with the trouble free heating & air conditioning operation and so far an absolute $ 900 a year maximum operating cost. Additionally, the Bakers found the Polar Bear Heat Pump System in their home to be extremely quiet and the heating to be remarkably evenly throughout, including all of the basement.

Located near Baysville, Ontario, Ken & Judy Robinson's home is a raised 2400 sq. ft. bungalow with a walkout on two sides. Total heating & air conditioning costs are less than $ 600 a year.
Their system is a 4.5 Ton Polar Bear unit attached to a "Pond, River or Lake Closed Loop". These systems simply have the plastic loop pipe laid into the bottom of the water body and operate very similar to the other closed loops.
Living up in Cottage Country and deciding which heating system to go with, Mr. Robinson's was concerned with the possible delivery problems of Oil or Propane, problems he would not have with the Polar Bear system.
The reliability of the Polar Bear unit was also very important, and Mr. Robinson knew that if any components did fail after the 5 year warranty period, access to parts was locally available. Polar Bear units don't burn combustible fuels nor do they have an odour like most Oil furnace installations.
The evenness of heat, the very low operating costs, comfort and safety were major factors for Ken & Judy Robinson choosing a Polar Bear Water Source Heat Pump System.
