Okofen boiler replaced an oil system. After a year including one winter it has been great. Quieter than our old Burnham, easy to remove ash once a month or so and has probably saved us at least 30 to 40 percent in fuel.

- A winter-to-winter comparison is tricky (for us anyway) but we saved at least $2,000 during the first year of operation. We expect the OkoFen will have paid for itself in about six years.

OkoFen Boiler provides heat and hot water. There's a six-ton bin in the garage for premium pellets. An auger and vacuum system automatically feeds the pellets to the boiler. We have a guaranteed price of $249 a ton for premium pellets. Told for equivalent BTU that works out to $1.99 a gallon for oil. But we honestly don't know if that's true.
Quiet and low maintenance. We like the idea the pellets come from New England.
Once every few weeks or a month depending on how heavily it is being used we have to unlatch a small container to empty ashes. Once a year we have a cleaning/maintenance. Cost us $75. Pellets are delivered by a huge truck with an auto-fill. Not with bags.
Efficiency or Sustainability Improvements:
Green energy and cost savings.
Make sure the unit is big enough. Ours had three BTU settings. When it started routinely hitting -20F the smallest setting couldn't keep the house warm. The installers made an adjustment to the max setting (41,000 BTU) and that took care of it. In retrospect I might have purchased a larger system.
Experience with Installer:
We were very pleased.
