It’s been a while since I updated expenses. Note that the rocket mass heater expenses included approximately $1,500.00 for CSA approved chimney materials. There’s a bit of debate about whether insulated pipe is required for the exit flue, since temperatures are ususally no more than 200 degrees F. However, as previously mentioned by Chris, we wanted to make the design as easy as possible and to meet with as little resistance as we could. The time for innovation may be on the next one! Also note that we were charged for a permit. It was actually $150, but I messed up and wrote the cheque from the Christmas account instead of the earthship account…boing! I don’t do that very often….
We are now about $6,000 over our anticipated budget as we weren’t budgeting for a rocket mass heater. We are not too worried about this as our contingency fund is fairly healthy. I expect that as we get into more of the systems (Chris and the electrician have started that component and we are next moving into plumbing) that our budget will continue to experience over runs, simply because we haven’t anticipated every detail. C’est la vie!
