이번엔 다른분들의 아이디어를 얻고자 올려봅니다. 점심시간 각 반별로 급식을 배식하여 식사시간을 갖는데 음식물을 반별로 남겨 오다 보니 모이면 꽤 많은 양을 버리게 됩니다. 음식물을 남기지 않는
좋을 방법이 없을까요? 좋은 아이디어가 있으시다면 알려주세요, 실천하여 음식물을 줄여보겠습니다.

Low Cost Home Projects:

Install a Tankless Water Heater

pledge i've done it

Description

On demand water heaters heat water only when it is needed at the source. These could be costly retrofits, but should seriously be considered if you are renovating or adding an extension.

I have a boiler type furnace... it heats my tap hot water. Relative to conventional water heaters (electric or fossil fuel driven), it is only a small internal tank that stores the 'continuous' hot water. However the T-stat setting on these furnaces allows only for continuous hot water so the furnace comes on whenever the internal water temperature drops below the low setting choice. Even though it is a small tank of water that is kept continuously hot, over time this really adds up : the furnace will come on EVERY hour depending on how high the low setting is. At the start of spring 2009 I began shutting my furnace of at the power switch -the red switch that says emergency. Many houses have 2 of these switches, one near the furnace, one in the stairwell. For 6 -8 months of the year, I do not need heat in my house due to wonderful solar heating through my large south-facing windows. Thus for 6-8 months this year I have turned the power on to my hot water heater ONLY for as long as I wanted hot water. I have saved at least a half a tank of furnace oil - so not only am I dramatically reducing my carbon footprint, I'm sawing a lot of money... A person living alone can find this inconvenience very easy to live with. A family that is committed to being green can also achieve this kind of saving with a bit of learning : everyone just needs to turn the red power switch on about 8 minutes before they want hot water to shower and then off when he/she is done. It is possible that for a family or someone unwilling to reach for the switch but willing to be set to a predictable time for their showers, dish washing, etc., a "programmable thermostat" could be wired into one of these red switches and the timer set to turn the power to the furnace 'on' for morning &amp; evening showers. An electrician who understands furnaces can recommend for or against this... ??? However, I'd like to see the thermostat on the HBO to have a setting for 'tap hot water on demand only' not just continuous hot. I would think this would involve little more than a valve to measure a drop in water pressure when a hot water tap is turned on which would then send electricity to the boiler- type furnace. If such a product is not made, are there any plumbers out there with a desire to invent something green?
