Efficient mekanism boiler/turbine? I've been watching videos on how to set these up and i have the basic grasp of it, however it seems like i'm not making much power for the effort it takes. My boiler was 19 years old and replaced by british gas - quotes from other local engineers were 500£ more expensive here in the highlands - and my gas bill went down massively. It highly depends on what is that boiler made for, how and most importantly: For how much?
1/ to increase temperature stability? Preheat-coils probably cheaper and more effective 2/ to.
