Electrical Resistance Heating
ERH vs. TCH: How to Choose Your Thermal Remediation Technology (and Why)?
“How do I choose between ERH and TCH?”
It’s one of the most commonly asked questions when considering thermal remediation, and in this webinar one of the industry’s leading experts will answer it. Join TerraTherm, a Cascade Company’s Vice President John LaChance as he introduces the basic operational theory and concepts for both technologies. He’ll discuss their application to a set of typical site conditions (e.g., low and high permeability zones in unconsolidated and bedrock formations) and contaminants (e.g., CVOCs), and highlight typical design approaches, assumptions, and the pros and cons of each.
John will share real-life examples of full-scale projects involving electric resistance heating (ERH) and thermal conductive heating (TCH), including detailed breakdowns and comparisons of costs. He’ll also touch on ETDSPTM, a form of ERH that employs active injection and extraction of water. If you have burning questions about how ERH and TCH stack up, this is your chance to get them answered.

ISTR Challenges Part 2: Electrical Resistance Heating and Steam Enhanced Extraction
Thermal Conduction Heating (TCH), Electrical Resistance Heating (ERH) and Steam Enhanced Extraction (SEE) are widely used thermal technologies capable of effectively remediating a variety of chemicals in various varying subsurface settings, yet sometimes operations do not perform as planned. An experienced thermal remediation contractor can help you anticipate and address site-specific challenges during full-scale thermal projects.
Presented by Vice President of Development, John LaChance and Vice President of Technology, Steffen Griepke, ISTR Challenges Part 2 covers some of the common issues that can arise at ERH and SEE sites, and discuss how they should be addressed. You’ll hear about scenarios involving
- significantly different soil electrical resistivities than planned
- slower than expected heat-up
- stray voltages and currents
- poor steam quality
- higher than expected mass removal rates
- lack of hydraulic control
- non-uniform steam delivery and heating
Join the discussion for insight to help avoid costly project delays in your next thermal project.
What is Electrical Resistance Heating (ERH) and How is it Applied?
New to thermal remediation? If so, understanding how the technologies work and how to choose the best one for your project can be overwhelming and confusing. Each heating technology has its own strengths and weaknesses depending on the site conditions and contaminants of concern.
In this 30-minute flash webinar, our VP of Development, John LaChance, and Senior Technologist, Erin Hauber, will give you an overview of Electrical Resistance Heating (ERH). You will learn:
- How ERH works,
- What geologic conditions it is best suited for,
- What contaminants it can treat,
- Design considerations to ensure a successful ERH project, and
- ERH sweet spots.
Which is Better? Electric Resistance Heating (ERH) or Thermal Conduction Heating (TCH)?
Electric resistance heating (ERH) and thermal conduction heating (TCH) have many similarities, and it can be hard to figure out which one is best suited for a specific project site. It’s critical to know the pros, cons, and differences of each because making the wrong call on technology selection can have expensive repercussions.
In this 30-min webinar VP of Development, John LaChance and Senior Technologist, Erin Hauber will give you a quick overview of the basic operational theory and concepts for both technologies and discuss their application to a set of typical site conditions. The webinar will focus on the pros and cons for each technology combined with real-life examples of full-scale TCH and ERH projects, including detailed breakdowns and comparisons of costs.
