today derik and i moved the point of use hot water heater closer to the kitchen sink. this decreased the time to hot water from about 30 seconds to about 25 seconds. more importantly, the installation is now far neater than it was before.
unfortunately, i did not take a before picture but both the plumbing tubes and the electrical lines were an aesthetic disaster. now they look great. it was a bit of a chore as it is difficult to get insulated pex tubes to look presentable.
the ecosmart point of use hot water heater is now neatly installed

today the house might have passed the blower door test. this test determines the air leakage in the house. although the house has a very small leakage, it is more than passive house will allow. so i have been trying hard to find leaks and patch them. today the measured leakage was
339 cfm. the requirement is 345 cfm. i have my hopes up that the passive house institute of the united states will say this is a pass.
michael’s computer shows the leakage to be 339 cfm at 50 Pa
