Frequently Asked Questions

What is the typical cost savings experienced by

utilizing EnerGo?

WAVE Home Solutions guarantees a minimum annual reduction of 10% of your heating and cooling energy usage. Many customers experience additional savings up to 30%.

Where do these savings come from?

The savings from EnerGo products are derived from numerous sources. Each installation has its own unique characteristics that change the proportional contribution from each source. EnerGo products improve system efficiency by:

  • Compensating for the required over-sizing of the system.
  • Reducing the number of burner or compressor cycles, which reduces the quantity of inefficient “start-up” portions of each cycle. The reduction of compressor cycles also reduces the current surges associated with starting up a compressor (usually 8 – 10 times normal run amperage).
  • Reducing ex-filtration losses due to over-heating or over-cooling the space.
  • Increasing average BTU output per run cycle.
  • Compensating for solar and wind loading.
  • Improving the thermal transfer characteristics of the heating or cooling system.

Will my home or business be less comfortable once an EnerGo

unit is installed?

No. One of the benefits of the EnerGo technology is a more consistent comfort level.

How does EnerGo protect the environment?

Since burners and compressors run less often and for less time, proportionally fewer particulates are vented into the atmosphere either directly from burner exhaust, or indirectly from decreased electric power consumption/generation.

Has the performance of EnerGo products been validated?

Yes.

Product performance has been validating by performance testing at internationally recognized research facilities including Brookhaven National Laboratories, NYSERDA, Brooklyn Union (KeySpan) and ConEd Solutions. Our products are also UL and ETL listed as meeting the highest safety standards. For a complete details go to our Reports section.

Will EnerGo void my manufacturer’s warranty?

No.

EnerGo will not affect your warranty and will actually reduce the normal wear and tear on your equipment.

Is it difficult to install an EnerGo unit?

No. Installation of an EnerGo product should be completed by a qualified professional. Typical installation times may vary depending on model and application, but are usually between 15 – 90 minutes.

What is EnerGo?

EnerGo is a line of energy-saving products for commercial and residential heating systems, central air conditioning systems and commercial refrigeration.

How does EnerGo work?

Our patented technology reduces energy consumption by optimizing system performance through real-time ‘load-demand’ analysis and control. In general, all EnerGo products monitor the performance of the heating or cooling system and dynamically calculate the optimal performance for burner or compressor cycles. As the system load changes, EnerGo automatically recalculates the optimal performance characteristics on the fly, ensuring that the system is always saving fuel and energy dollars. In real time, our products delay the start of a cycle so that the comfort of the space is maintained and the heating or cooling system is fully utilized. This cycle modification results in a more efficient use of the heating or cooling system, with subsequent reductions of energy consumption, wear and tear on the equipment, maintenance requirements and pollution.

Why can’t my heating or cooling system perform this

optimization without the EnerGo?

If a heating or cooling system is to perform properly (that is, keep a space properly heated, cooled or refrigerated on the hottest or coldest days), those systems must be sized according to the highest or lowest ambient temperatures they are to encounter. These worst-case hottest or coldest days (Design Days) occur only a small fraction of the time. Usually, though, the system is relatively over-sized for the demand, which causes the system to run, or cycle, less optimally.

Does the EnerGo change the efficiency or operating

characteristics of a burner or compressor?

No.

The EnerGo product line does not increase a burner’s or compressor’s efficiency. We improve overall “System” efficiency by dynamically changing the way that the burner or compressor is reacting to the needs of the load placed upon it.

If the burner or compressor is held off from starting its cycle

longer, why doesn’t it run longer for the same amount of time?

The very nature of a heating or cooling system requires it to either generate heat or extract heat faster than the load (space) loses or gains heat. (If this were not the case, the heating or cooling system would not be able to keep up with the demand and maintain the temperature, and it would run continuously.) As a consequence, system run-time is increased by only a fraction of the time that it was held off, resulting in a net reduction of energy consumed with no change in space temperature.

If the burner or compressor is held off, why doesn’t the space

temperature change?

The answer depends upon the type of system.

Hot Water and Steam Heating Systems
There is substantial energy stored in the heating medium (water / steam) that can be extracted and used during the hold-off period without any substantial loss of output. This heat extraction is possible since the boiler can generate heat faster than it can be extracted. It also generates more heat than what can be extracted. Those two facts taken together explain why the space temperature doesn’t change while the burner cycling is optimized.

Forced Air Heating Systems
The rate and quantity of heat that a forced air heating system can add during a given period of time is greater than the amount of heat that can be lost by the load (space) for the same period of time. More simply, the system can heat the space faster than the space itself can cool off. In response, the burner must be cycled in order to maintain the desired temperature, otherwise the space would be over-heated. Air is used to inject heat into the space. Air has a very low mass and thus a short time-constant (the change in temperature per unit of time). Comparatively, items in the heated space—for example, people, walls, furniture and so forth—have considerably more mass and, thus, a longer time-constant. These higher mass items have a much greater thermal inertia. Thermal inertia (time-constant) indicates how fast or slow an object can be intrinsically heated or cooled over time. Higher mass items generally take longer to heat up or cool off than air. Since the burner is held off for only a small percentage of time, relative to the time-constants of the higher mass items, temperature fluctuations are virtually non-existent, and the temperature of the space is maintained while using less energy.

Central Air Conditioning Systems
The rate and quantity of heat that a central air conditioning system can remove during a given period of time is greater than the amount of heat that can be gained by the load (space) for the same period of time. More simply, the system can cool the space faster than the space itself can warm up. In response, the compressor must be cycled in order to maintain the desired temperature, otherwise the space would be over-cooled. Air is used to extract heat from the space. Air has a very low mass, and thus a short time-constant (the change in temperature per unit of time). Comparatively, items in the cooled space—for example, people, walls, furniture and so forth—have considerably more mass, and, thus a longer time-constant. These higher mass items have a much greater thermal inertia. Thermal inertia (time-constant) indicates how fast or slow an object can be intrinsically heated or cooled over time. Higher mass items generally take longer to heat up or cool off than air. Since the compressor is held off for only a small percentage of time, relative to the time-constants of the higher mass items, temperature fluctuations are virtually, non-existent and the temperature of the space is maintained while using less energy.

I use a programmable, setback thermostat or a multi-zone

thermostat. Will EnerGo make any difference?

These more advanced thermostat controls provide more fine-grained control of the temperature limits that trigger a call for heating or cooling by changing the trigger limits for a particular room (zone) or at a particular time (setback). Other than making the call for heating or cooling, these controls do not monitor or optimize the operation of the burner or compressor. As a consequence, the burner or compressor is still subject to the frequent and inefficient on/off cycling that is inherent in the design of the system.

Implementing an EnerGo Economizer with a setback thermostat or a multi-zone control will still provide a minimum 10% reduction in energy consumed beyond what these controls might be providing already. These savings are derived from the dynamic, real-time burner or compressor cycle optimization that only the EnerGo Economizer provides.

Is it difficult to install an EnerGo unit?

No. Installation of an EnerGo product should be completed by a qualified professional. Typical installation times may vary depending on model and application, but are usually between 15 – 90 minutes.

Once the unit is installed, how do I operate it?

Once the unit is installed on your heating or cooling system, there is nothing else for you to do. The EnerGo control does its works automatically with no adjustments, reprogramming or resets.

What sort of maintenance or seasonal adjustment does the

EnerGo require?

None.

Once installed, the unit requires no maintenance, seasonal adjustment or reprogramming.

Will I have enough hot water when I am using the EnerGo with

my boiler?

Since many boilers also provide heat for domestic hot water, our design can accommodate that situation with no loss of domestic hot water. The unit also monitors the domestic hot water outflow pipe. If this sensor detects a demand for domestic hot water, it will override any burner firing delay, ensuring that hot water is always available for domestic use.
