	RE: Say hello and introduce yourself By cathodeRay, 3 weeks ago Forum Introductions, Forum Rules & Updates

	If you know what you need the maths is straightforward. Assume water in is at 10C and shower water at 40C. The heat capacity of water is 4.2kJ/lC So for each l of shower water you need 30*4.2kJ = 12...
