Interesting read.. sounds good matthew goodluck i'd be keen to see the work in progress
matthew i'd recommend a good heatpump, they can cool and heat rooms. a fan heater runs at 100% efficiency, whereas heatpumps can run up to 400% efficiency! that is a huge cost over time esp as power prices will likely slowly climb year to year.
oh one question, i've observed in a lot of areas now you have to pay for water as a seperate bill, how are people finding this cost in running fishrooms/big tanks in those areas? i assume this would substantially affect the quantity of water changed. for example in Tauranga there's water meters but in Hamilton there isn't; and I believe the price of the rates are similar. In Hamilton I was changing 200L of water a day for my discus. anyone know what that would cost?
