Testimonials
"The guide was super informative to reference to determine the right kind and size of water heater for our basement conversion ADU project. We learned so much from reading through the section on hot water heaters. We are excited to see what else we can learn from the guide on future projects!"
-Jen Agius, Studio M MERGE
"This guide is a must have for builders and designers in the ADU space, and everywhere else for that matter. There is always something new to learn, and this guide will help you up your energy game A LOT! It would be malpractice to not own this guide and reference it regularly."
