No. The same loop works for both. All that happens when changing from heating to cooling, or vice versa, is that the flow of heat is reversed. The buried pipe, or "ground loop," is the most recent technical advancement in heat pump technology. The idea to bury pipe in the ground to gather heat energy began in the 1940's.

We are familiar with many manufactures of different types of heating and cooling systems. Whether you are looking for gas, oil or electric, we can help you find the best suppliers around. Top

Yes. Just use the recommended mountings and, if noted in the instructions, leave a small air gap around equipment. Most products are rated to operate from -40oF to +149oF

You may need the UFAN if you are using the Ultra in particularly stressful situations: near the ceiling with the model lights on full all day, with warm temperatures in the studio, or if the light is enclosed in a soft box or other similar apparatus. Basically, the light should not get so warm that its uncomfortable to hold your hand on the case just behind the head area where the reflector mounts.

Many heating and cooling professionals are not aware of the benefits of Powerzoning because they're not trained to understand how your home's indoor environment works. Most HVAC professionals are trained to install a properly sized (BTU) system and run ducts appropriately, and they do a very good job of this, but their understanding of how the system can get the best results for a homeowner can be limited.

The most common complaint we hear, is that one area of a house is hotter or cooler than another area. This is usually caused by poorly sized ductwork. This can only solved by costly heat load calculations and redoing your entire duct system. A more simple solution is to take advantage of two-stage heating and cooling. When you have single stage heating and cooling you are getting 100% of the heating or cooling every time the thermostat calls for it.

One of the things that makes a heat pump so versatile is its ability to be both a heating and cooling system in one. You can change from one mode to another with a simple flick of a switch on your indoor thermostat. In the cooling mode, a geothermal heat pump takes heat from indoors and transfers it to the cooler earth through a closed loop underground system or groundwater wells.

In winter, the system extracts heat from the ground, which is converted to warm air (or water) for space heating, water heating or radiant floor heating. In summer, the compressor puts heat from the building into the loop fluid, and this heat is 'rejected' into the ground outside to provide cooling for the structure.

The Airomax system will deliberately cause "air turbulence" to occur in your shop. The turbulence is required to keep smoke, dust, and over-spray particles suspended until they are captured in the filters. The turbulence prevents stratification of heated or cooled air and equalizes the air temperature at the floor and ceiling. Usually, the heating and cooling system will cycle less frequently when an Airomax system is in operation. This reduces the cost of heating and cooling air.

Geothermal is a version of electric heating and cooling pulling heat from the mass of earth surrounding your house in the winter and moving heat from your house back to the earth in summer. Tapping hot water and using geothermal systems for air conditioning can make economic sense. We will be happy to explore use of geothermal energy with you in our Improvement Analysis.

Sizing your system is very important. In today’s economy of high fuel costs, it is especially important to make sure you are getting the most efficient system for your square footage – not over, not under. We can help you pick the right size heating or cooling system for your situation. Our knowledgeable staff will assist you in comparing gas furnaces and air conditioning systems. They know the furnace ratings and everything you need to know to make a well-informed decisions.

Because RenewAire recovers most of the heat energy in the exhaust air (in the winter), this is the least expensive kind of ventilation system to operate. RenewAire is also much less expensive to operate than a dehumidifier sized to accomplish a similar amount of wintertime moisture removal. In fact, most people report little or no impact on their heating or cooling bill, but this can vary depending on many factors.

Look for contractors that are N.A.T.E. certified, and factory trained and certified. They should do a ???Manual J??? heat load analysis to properly size any new equipment. Make sure they are licensed, bonded and insured, and ask for proof of this. Be sure they permit all applicable work. Check their record with the state Attorney General???s office, Better Business Bureau and referral services like ???Angie???s List???.

With the system set to heat, when the set point temperature is raised or lowered past the room temperature, the thermostat will make a soft click sound within about 5 seconds. Usually the sound indicates correct thermostat operation. If the heat does not come on after raising the temperature and hearing the click, check the fuses or breakers, make sure the furnace is switched on, and verify the blower compartment door is closed properly.

The affect on your climate control bill is minimal, based on the fact that the E·Z Breathe® draws air from the very lowest part of the home. This air is always the coldest air in the home to begin with, and due to its damp nature it is also the hardest to heat. Once in operation the E·Z Breathe® moves the colder air out, and since dry air is easier to heat than damp air, your heating system does not work as hard to maintain the desired temperature.

Yes. A GSHP 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 GSHPs can save you up to 50% on your water-heating bill by preheating tank water.

YES! the NFPA (National Fire Protection Association) 211 states that each heating appliance MUST have its own flue. It is illegal to "share" flues.

What engineers refer to as 'ground loops' are caused by several factors. A 'ground loop' is a noise that is often created when two pieces of electrically charged equipment are connected together and their differing ground reference voltages interact. This is often unpredictable, whereby the system noise may be 'acceptable' in one venue and be absolutely horrendous in another. Transformers isolate the two devices by converting the electrical current into a magnetic field and then back to current.

One of the most difficult troubleshooting tasks for the audio practitioner is finding the source of hum, buzz and other interfering signals in the audio signal. Often these are caused by "ground loops." This unfortunate and inaccurate term (it need not be in the "ground" path, and the "loop" is not what causes the problem) is poorly understood by most users of audio equipment.

A Ground source heat pump (GSHP) is a low energy system using the near constant temperature of soil or surface water, captured by a network of underground pipes and boosted via a pump and compressor to provide heating to a building ideally through an underfloor system. As an addition if the system flow is reversed, the underground pipe work works as a heat sink providing cooling for the buildings interior.

Both Ground Source and Air source heat pumps can be linked into existing heating and hot water systems and will work well and efficiently. However they work even better well with underfloor heating.

NCI-certified contractor will first ask you questions about the system, what you like and don't like about it, problem areas, air quality concerns, health issues, etc. He should then perform some preliminary testing to determine the condition of your system, the biggest problem areas, and so forth. This is generally performed using several instruments including a manometer which measures your systems pressure, much like a doctor checks blood pressure.

Adjustments in temperature may take up to several hours to be felt. In many instances, the systems are working for an entire building, not just a single office or classroom. Changing the thermostat does not cause an instantaneous change in temperature. If you do call in with a complaint of being too hot or too cold, please be patient while the adjustment takes effect. For temperature problems affecting critical research and/or animal welfare, please call 8-7208.

The fan in the heating/cooling system should be set in the 'always on' position, instead of the auto mode. The EnviroSept can't clean the air and reduce dust if the fan is not running. Circulating the air constantly provides the added benefit of elininating hot and cold spots inside the home.
