Automatic Ventilation Control with Broan-Nutone's Overture: Customizable, Modular Fresh Air System

Corbett Lunsford

Places are different, homes are different, families are different. There IS NO SINGLE SOLUTION for ventilation, and that's the way it's likely to stay- so the more modular, customizable components we have access to, the better.

In addition to having some of the most advanced ERVs in the world (stay tuned for more on that), Broan has now made customized, modular ventilation systems much more practical with this lineup of Overture controls: room sensor, wall control, and smart plug- all linked to the algorithms in an app.

The Overture system can control exhaust fans, supply fans, make up air dampers, and ERVs/HRVs- we hope they will continue to push forward into controlling air handlers, dehumidifiers, humidifiers, and more.

Tweaking our Home's Water System with Chronomite Point-of-Use Water Heaters

Corbett Lunsford

I've heard lots of myths and misinformation about water heating, and lots of 'silver bullet' products that don't actually do what they claim. Here's a refresher on a bunch of things that you might not have ever seen or considered before, and the testing to prove they work. Featuring Chronomite instantaneous tankless water heaters with a low flow activation down to 0.2 gpm, microprocessor control, and self-cleaning features, along with our system’s efficient PEX one-pipe plumbing, and even ventilation location selection.

Unboxing our Instantaneous Tankless Water Heaters

Corbett Lunsford

At the suggestion of a YouTube fan, we did a bunch of research on point-of-use instantaneous water heating, and discovered Chronomite. See what we're installing on our performance-tuned house, and hear why we're going a completely different direction than most of our fellow Americans.
