How to Save Money
Free or Inexpensive Steps to do Right Away
Costlier Steps to Consider
- Turn the thermostat down three more degrees in the winter, up three more degrees in the summer.
- Tighten up your building envelope:
- Seal carefully around windows and doors so they close tightly.
- Use less hot water.
- Wash only full loads.
- Wash more loads with cold water
- Shorter showers
- Low flow shower heads
- Low flow or aerating faucets.
- Insulate your hot water tank. Add an insulation blanket around it.
- Energy efficient windows.
- Better insulation in your attic.
Less importantly, in the exterior walls.
- Call in consultants:
- An Infrared camera will show your heat losses
- A cost/savings analysis of various options based on
latitude & weather, site & roof orientation, foliage cover,
your energy bills, etc.
- Photovoltaics, Ground Source Heat Pumps, etc., etc. (Poor economic returns)
- Solar heat every swimming pool. An S-connected rack of black ABS
pipes on the roof connecting from the pre-existing pump output and
back to the pool. Simple, inexpensive, effective. Extends the
swimming pool season into fall and spring. This is the strongest
solar heating application of all.
- Solar Water Heating In Seattle:
- use Evacuated Tube (heat pipe) systems.
- Washington State has a sales tax exemption for CRCC rated
solar water heaters, purchase, installation, and service.
So that's around 9% cost reduction, valid between 7/1/2006
- US Federal Income Tax provides for a tax credit (much better
than a deduction!) to individuals adding solar water heating
systems to their principal residence, amounting to 30% of
the first $6667 of cost (i.e., a maximum credit of $2000),
valid from 2005 to 2008 (recently extended to 2016), IRS Form 5695.
