Talking Points

Recent interactions between the hosts and their guests.

The OG Heat Pump YouTuber | Emilie Romain
Q: What was the intention behind EcoBubl's training and showroom components, and how did COVID affect those plans?
We aimed to be a renewables distributor and training center, but COVID disrupted hands-on training; we pivoted to manufacturer trainings and eventually built a showroom and a training setup that still offered value to the public and professionals.
Smart Heat Pump Control with Havenwise
Q: Can Havenwise fix a crap system?
It can optimize performance and extract the best possible costs from a system, but it cannot physically fix hardware faults or bad install; that requires remediation by a technician, though Havenwise can surface the issues and support remote troubleshooting.
Heat Loss with Steph Willis from Spruce
Q: What should homeowners look for when vetting an installer on heat loss work?
Homeowners should ask how the installer determines heat loss, whether they use a whole-home infiltration approach, and whether they consider room-by-room emitters. A good installer will discuss tradeoffs between upfront costs and running costs and tailor solutions to the home and homeowner priorities.
Heat Loss with Steph Willis from Spruce
Q: How has Spruce changed the approach to heat loss calculations?
Spruce moved away from per-room ACH guesses to a whole-home infiltration model, distributing a more accurate value across rooms, and encouraging use of tests like blower door or pulse testing when possible to reduce uncertainty.
Heat Loss with Steph Willis from Spruce
Q: Why did the old ACH-based guidance cause problems for heat pump sizing?
The old guidance used fixed ventilation change values that were often unrealistically high, leading to inflated heat loss estimates and oversized heat pumps, plus unnecessary radiator changes and higher costs.
