Questions & Answers
How much can we save with Geothermal?
Savings depends on your current heating system and type of fuel used. Geothermal typically produces savings of:
- 70% to 80% savings when converting from propane gas
- 40% to 60% savings when converting from natural gas
- 25% to 30% savings when converting from Air Source heat pumps
Can you guarantee the system will perform as planned?
We guarantee the system will perform as designed. Each design is based off 30 years average temperatures for your area. Plus, we typically design our systems on the conservative side planning for 1 additional future heater.
What is the difference between a Water Source and Air Source Heat Pumps?
Water Source uses the heat stored in water from lakes, wells, cooling towers and even the ocean and the heaters runs irregardless of the outside temperatures and weather conditions.
Air Source uses the surrounding air. However, these type of heaters shut down when the air temperature reaches about 45 degrees leaving your pool cold by morning.
If the source water temperature is 72 degrees, how can we heat the pool to 85 degrees?
Think of it like your air conditioner in your home only in reverse. Each heating unit strips about 8 degrees from the source water and that heat is absorbed into the Freon in the source side heat exchanger. The Freon is then compressed via a scroll compressor which super heats the Freon to 140 degrees just prior to its passing through the pool side heat exchanger.
How do you keep the wells from being in the way or an eyesore?
The well heads and electrical takes up a small footprint – typically 12 inches in diameter and 15 inches in height. We make every effort to place the wells in locations away from any foot traffic or parking lots. We can landscape around the well head if desired to minimize their visibility.
How much space does the installation take up?
Each installation is unique, but each heater requires about 42″ wide x 48″ deep x 36 high. We can stack them if space is tight as well. There is always a solution.
With the relative high system cost, are there alternatives to afford a geothermal system?
The only disadvantage to converting to Geothermal is the capital investment required by the community. We solved this problem by offering our systems under our Rental Agreement which requires No out-of-pocket investment as the installation costs and maintenance are rolled into one fixed monthly payment.
Can a spa be heated using Geothermal?
We use the Aquacal WS03 water source heat pump for spas under 2,000 gallons and WS05 heat pump for spas over 2,000 gallons. They are able to maintain 104 degrees without any issues.
Gas heaters stain the pool interior green ... Will Geothermal Heaters stain our pool?
Gas heaters use copper for their heat exchangers. Imbalanced pool water erodes the copper on a molecular level where it eventually deposits itself on the pools interior surface. Geothermal heat pumps use titanium heat exchangers which for all intensive purposes is impervious to chemical erosion.
