Geothermal FAQ

1. What is a geothermal heat pump?

A geothermal heat pump is an electrically-powered device that uses the natural heat storage ability of the earth and/or the earth’s groundwater to heat and cool your home or business.

2. How does a geothermal heat pump work?

Also known as GeoExchange, earth energy, or ground source heat pumps, is a method of heating and cooling buildings, and providing domestic hot water. The earth’s natural heat is collected using a series of pipes in the ground, called a loop. The loop carries a fluid that picks up the heat from the ground and transfers it into the house where a heat pump raises the temperature and transfers it into an air or water stream for distribution throughout the building. In the summer the system is reversed. Heat is taken out of the building and transferred to the ground where it is stored until required for heating.

3. How efficient is a geothermal heat pump?

A geothermal heat pump is the most efficient residential heating and cooling systems available today. With heating efficiencies 50 to 70% higher than other heating systems and cooling efficiencies 20 to 40% higher than available air conditioners. That directly translates into savings for you on your utility bills.

4. Are geothermal heat pump reliable?

Geothermal heat pumps have been used in Europe for well over 50 years and in North America for approximately 30 years. Heat pumps have an expected life of approximately 20 years. Properly designed and installed systems can be expected to run trouble-free for decades. The only real requirement is changing the filters and conducting periodic checks, just like a furnace.

5. Can one system provide both space heating and cooling for my building? And what about heating hot water?

Yes. A geothermal heat pump can be a combination heating/cooling and hot water heating system. You can change from one mode to another with a simple flick on your indoor thermostat. Using a desuperheater, some geothermal heat pumps can save you up to 50% on your water-heating bill by preheating tank water.

6. Does it cost more to install a geothermal heat pump?

A geothermal heat pump will cost more than a conventional heating and air conditioning system, but in most cases the homeowner will save money from the first day they move into their new home. By including the cost of the geothermal heat pump in their mortgage, monthly payments will increase but their monthly utility payments will decrease by an even bigger margin. The result is that the homeowner will be saving money from their very first month in their new home. And as the price of energy increases, so will the savings.

7. Are there governments provide grant and incentives for installing a geothermal heat pump?

Yes. Government incentive programs are available in North America and provide up-front grants to homeowners and installing geothermal heat pumps. Check with the local government official in your area or contact toy local Tili representative for guidance.

8. Can a geothermal heat pump be added to my fossil fuel furnace?

Yes. Split systems can easily be added to existing furnaces for those wishing to have a dual-fuel heating system. Dual-fuel systems use the heat pump as the main heating source and a fossil fuel furnace as a supplement in extremely cold weather if additional heat is needed.

9. What about comfort?

Geothermal heat pump system moves warm air (90-105 deg F) throughout your home or building via standard ductwork. An even comfort level is created because the warm air is moved in slightly higher volumes and saturates the building with warmth more evenly. This helps even out hot or colds spots and eliminates the cold air blasts common with fossil fuel furnaces.

10. Are geothermal heat pumps guaranteed?

Nearly all geothermal heat pump manufacturers offer a warranty for major components that is equivalent to the warranties for conventional heating and cooling systems. Manufacturers of plastic pipe used for ground loops warrant their products for 50 years. Contact a Tili representative for warranties details for their TE series geothermal heat pump product line.

Mini Speed Ductless Air Conditioning Systems FAQ

1. How do I determine what size of air-conditioner to get?

Selecting the right size of A/C is important because over-sized and under-sized systems can reduce your comfort and increase your utility bill.

A system too large will cool your home too quickly and will cause the product to start and stop more, which will shorten the life of the air conditioner. If the size is too small, then the A/C will continually run more which will increase energy costs and may not even cool the room down to a satisfactory level.

Air conditioning systems sizes are determined by a number of considerations such as home size, type of foundation, building materials, insulation, weather stripping, attic ventilation, and other factors. However, you can get a good sense of what size of air-conditioner you will need based on the following room area chart:

Room Area(sq.Ft) Recommended BTU
250~300 7,000
350~400 9,000
450~550 12,000
600~700 16,000
700~1000 18,000
1000~1400 24,000

2. What is a heat pump?

A heat pump is a feature added to a conventional air conditioner that can also provide heat when needed. In summer, the air conditioner absorbs heat from the dwelling and expels it outside. In winter, a heat pump will extract heat from the outside unit and circulates it inside the dwelling. A heat pump can use 30 to 60 percent less energy to supply the same heat when compared to an electric furnace with a resistance-heating element.

3. How does a ductless air conditioning system work?

A ductless air conditioner, also called a mini-split system, has two major components: a unit mounted on an inside wall that delivers cool air to the room and a condenser unit mounted on the outside of the dwelling. The ductless system is easy to install because there is only need of a 3 inch hole to be drilled through the wall, which connects the refrigeration lines to the outside unit. There are also electrical and condensation (water) drainage lines running through this outlet as well.

Tili’s ductless system also has a thermostat, which maintains good temperature control and will keep the room at a constant, comfortable temperature instead of blasting on and off. Not only are Tili’s ductless systems very quiet, they also have an automatic airflow design that you can adjust with a remote control. You can set the airflow in different sweeping directions as well as how strong you want the flow.

In addition, unlike a window air conditioner, you don’t have to move a mini-spilt system in and out of the window as the seasons change. You also have much more security because you don’t have the “open window” invitation for an intruder, which makes it much easier to install an efficient alarm system as well.

5. What is a portable air-conditioner?

Portable air-conditioners were developed to provide cooling when a window unit or other types of A/Cs are not suitable. They can also be used to supply extra cooling to temperature sensitive areas during extreme weather conditions.

Portables are very practical can set up very easily with minimum effort. Usually, a plastic panel is placed in a window and then the window is closed to seal it. This frame is only 6 inches wide making it safe from intruders. Then, the exhaust hose is hooked up from the air conditioner to the window frame and then the unit is ready for use.

Another benefit with a portable you can move it around your home. For example, you can watch TV with it in the den, then take it to bed with you at night.

6. Why choose a Tili portable air-conditioner?

Putting Tili’s quality aside, we also have superior design characteristics. In traditional air conditioner designs, condensate water collects in a tank, which must be dumped periodically. Tili’s advanced design, however, will continuously burn off this troublesome condensate through the exhaust system, which is vented out through the window vent. This process eliminates the hassle of periodically dumping a collection tank.

Tili also has one of the best warranties in the business with a one-year on labor and parts, a five-year compressor warranty.
