Jäspi Tupla is a combination boiler that can use wood and bio-oil as an energy source, depending on the situation, and electricity as a backup heat source.
Good insulation and modern combustion technology guarantee high efficiency. The efficient domestic water coil gives a good hot domestic water yield even with heavy consumption.
In Jäspi Tupla, the bio-oil nest and the wood nest are completely separate, but only one flue is still needed to connect to the chimney.
USING BIO OIL: The boiler works with high efficiency. The boiler is serviceable from the front and easy to maintain. With modern burner technology, if properly adjusted, the boiler needs to be cleaned 1-2 times a year. The delivery of the boiler includes a pre-installed burner thermostat.
USING WOOD: The spacious wooden nest allows the use of trees of 0.3 meters (Double 1) or 0.5 meters (Double 2), depending on the model. The new wood-side burning technology enables cleaner, more environmentally friendly and more efficient burning. When heating with wood, we recommend always connecting an energy accumulator to the system. In this case, the boiler can work at full power and combustion is cleaner. The storage tank has enough heat for both hot water and heating, even for several days in the summer.
