I am currently working on an update to the Turtlerock Masonry Heat website (www.turtlerockheat.com).  Part of this project includes re-visiting projects from the last few years and taking photos of the heater inside the finished home. Often times the heaters have been in use for at least one winter. It's a great opportunity to get feedback on heater performance and see what the strengths and weaknesses are for each particular design.  I'm generally very happy with what I have seen in terms of heater performance, especially with heaters built inside modern, tight, well-insulated homes.  In these cases owners are getting as much as 100% of the required heat output for the home.  In older, less insulated, leakier homes heaters are still performing well but are sometimes not able to keep up with the heat loss, so on the coldest days supplemental systems are being used more often.  Sometimes these results are more or less predictable in project planning, but every time a project is revisited the overall knowledge base regarding performance takes another jump forward.
