Fantastic boiler
I love this boiler! Runs my pm research #3 engine for 30+ minutes and takes 1minute to start boiling and creating pressure

Great boiler for the price
Great boiler for the price, i used it on my PM research 3 engine and it runs perfectly. Only cons: burners run out of fuel quickly, and no valve to adjust steam flow.
