A FASCINATING New Power Generation / Water Heating Solution w/ Enginuity

Jacques Beaudry-Losique, the CEO of Enginuity Power Systems, joins Nathan Orr live at AHR 2022. Enginuity manufactures energy-efficient engines that produce more power than traditional engines and recover waste heat to act as water heaters. Enginuity engines can run on propane and natural gas to help you run almost entirely off the grid and participate in electricity buyback programs. These units operate independently of the electrical grid and can act as generators during power outages and have a small footprint. However, a backup battery system is recommended for these units to maximize efficiency.

Enginuity has a residential and commercial line. The E | ONE is best suited for residential applications, and the E | TWO is better for heavier commercial applications. The U.S. Army has been one of the most prominent supporters of Enginuity, which also manufactures its units exclusively in America.

Distribution is done through a third party, including business owners and technicians; Enginuity doesn’t deal directly with homeowners or building staff. As a result, A/C service technicians, installers, plumbers, and refrigeration technicians may end up being the people in the middle who do maintenance on Enginuity generators.

After this conversation with Jacques, we are very interested in seeing what the future holds for Enginuity and combined appliances.

Jacques and Nathan also discuss:

The electrical grid’s stability
Enginuity’s revolutionary piston design
Ease of startup and commissioning
Pricing questions
Enginuity’s target market and training resources for that target market
Engine life expectancy
Enginuity’s projected rollout timeline and expansion plans
Decentralizing power dependence
Solar vs. fossil fuel energy
The problem with power plants

HVAC School – For Techs, By Techs

Real training for HVAC ( Heating, Ventilation, Air Conditioning and Refrigeration) Technicians. Including recorded tech training, interviews, diagnostics and general conversations about the trade.

Chris Hughes and Steve Rogers from The Energy Conservatory discuss TEC’s TrueFlow technology and its crucial role in predicting airflow issues in the sales process, particularly for heat pump retrofits. They explain how the TrueFlow app helps contractors accurately measure both static pressure and airflow in existing systems, enabling them to predict whether proposed equipment changes will work effectively. This is especially vital when considering the growing trend of replacing gas furnaces with heat pumps, as the airflow requirements can differ significantly.

The conversation delves into a detailed example of replacing an 80% efficient 48,000 BTU furnace with a heat pump. They demonstrate how the airflow requirement would nearly double from 652 CFM to 1,200 CFM, potentially causing the static pressure to quadruple due to Fan Law 2 principles. This dramatic increase could lead to significant performance issues if not properly addressed during the system design phase. The experts emphasize that using TrueFlow during the sales process allows contractors to identify potential problems and necessary modifications before installation rather than discovering issues during callbacks.

The discussion also covers the ideal workflow for system assessment and sales, starting with customer comfort evaluation and proper load calculations. It’s important to reduce loads through envelope improvements when possible, particularly in cold climates where heat pump retrofits are becoming more common. Proper system sizing often means going smaller rather than larger, contrary to common industry practices, and the worst HVAC systems are often found in expensive custom homes rather than tract housing.
