[QUOTE="Huevos, post: 635367, member: 301161"] I was talking about what can be done in the home to save energy. It kind of goes hand-in-hand with your number one. Here I'll do anything to save energy but to be honest it is really related to money. If it doesn't save money I won't do it. For example to cook and heat water (on demand boiler) I use butane. I get through eight or nine 12.5kg cylinders a year. At 10.50€ that's about 90€ a year. To stop using that gas I could build my own solar cooker and water heating system, but even a DIY system would cost 1000€+ so I'd be looking at 10 years to break even. BTW people are talking about convection to circulate and a water tank etc. Some of they DIY ones I've seen here are a lot simpler. A bank of radiators in sealed insulated boxes all connected in series. The water in the radiators is mains water. The capacity is only about 25 litres and then the cold starts to flow but that's plenty to have a shower and the new load heats up in minutes. But we do get plenty of sun here. Even with no preheating (tap open condition) with 10m2 of radiator you are probably getting 3kW of energy into the water. [/QUOTE]
