• We have had our Keystoker 90,000 btu stoker stove for about 10 years. It is one of the best investments that I have ever made. We have a ranch house with a full finished basement and this stove keeps the main floor and basement at 72 degrees all winter. We usually burn about 2 tons of rice coal per heating season. The support by phone and email are outstanding. Great company.

  • Best investment I’ve made to our home, yet nice even heat and economical, too.

  • Best investment I ever made in our home! Heats our 2025 sq ft home all winter at 72 degrees on just 3 tons of rice coal which equates to about $100.00 per month.

  • K6 older style radiant floor in garage…and pumping 110 feet underground into house to heat 3600 ft house….. garage is roughly 1200 square feet surprisingly the k6 throttles away and heats it all…. house is also on 6 zones

  • Ka-6 boiler from the 80’s. Installed it this past summer, it’s 150ft from the main house. It heats the shop it’s in with a water to air coil, and the house with cast iron radiators and a water to air coil in the basement. Warmest my house has ever been for less money.
