Insulating the studio was and still is big on the mandate. . . phase two is energy consumption!  I”ve long been looking at Solar and Geothermal options, but  right now upgrading the equipment is a much more reasonable option.  I was quite suprised to learn that the old furnace (30 years old now) could be operating at an efficiency as low as 50%!!!!!

I decided to go with this Marvel of the furnace world. . . a Lennox!  Where my old furnace produced very hot exhaust,  this one makes water and a warm steam. . . i’m not kidding when i tell you its a most pleasant exhaust!  This baby is 98% efficient. .  almost twice as efficient as the old unit.

this is the other unit,  a Bosch BWH C 800 Tankless hot water heater.   Hot water is now by on demand and unlimited. The efficiency is 92% compared with a tank around 60%.   Another advantage was getting rid of the big water tank and creating more room, the downside with these units however is a 20 second warm up time  for hot water and temperature fluctuations based on load, but all in all i think the savings are a good trade off.  I’m considering a solar preheat for the water which would raise the efficiency even further.

One pet peeve i want to share is that there were no incentive programs for any of my upgrades.  I will probably never see the payoff by the time i sell the building other than the satisfaction of leaving less impact on the world.  If you purchase the same furnace as a homeowner you get approx $700 back from bc hydro and the gov’t., but none of this applies if you own a commercial building!  No wonder so many buildings are still poorly insulated and running on outdated equipment.
