Review of Ecoboiler 16 HE

Poor output to water - not what's wanted from a boiler stove

Nick Rogers 11 years ago

Installed 16HE boiler in November and have tried everything to get a decent output to water. Regardless of burning wood or "superheat" smokeless coal, this boiler will only output a maximum water temp of 60c.

Testing at boiler input and output pipes, when the input is about 35c the output can be 52c, then when the accumulator is returning 52c to the boiler input the max output is only 60c. And nothing will get it to output hotter than 60c, which for radiators is useless. Cold water in the rads mixes with the flow from the accumulators bringing the temp down to 50s and quickly to 40s.

A boiler stove should output 80c and this one doesn't.

    Hey did you ever find a solution for this? I have just had my open fire replaced with an eb12 and cant get the water hotter than approx 58 degrees even when burning flat out!

    We have finally got a conclusive measurement of the output of this boiler, having fitted a water flow control and flue stabiliser. The output at 7 litres a minute and 17Pa flue draught is 5kw to water. This is using a mixture of wood and "superheat" smokeless coal.
