  • Q&A: Soundproofing a Through-Wall Air Conditioner

    Q. My neighbor has a noisy through-the-wall air conditioner that runs day and night. So that I could get a better night's sleep, I thought I would offer to build him a soundproof box he could place around the AC unit, before I resort to more drastic measu

Air Conditioning

  • Heat pumps are refrigeration- cycle devices that use electricity to move and concentrate heat energy, and can be used for both heating and cooling. Although electricity is required to run a compressor,the energy needed to deliver a given quantity of heat with a heat pump is typically a fraction of what it would take to provide the same amount of heat with resistance baseboard heaters or wall-hung units.

    Staff Report: Blackout Power Solutions

    The small, gasoline-powered portable generator is the classic ad hoc response to a major power outage. Yet it may be the homeowner's worst possible choice. Able to provide only enough output for a few lights and a refrigerator, gas-powered generators need frequent refueling and make a lot of noise...

  • Rinnai. The RH360 solar reheat kit provides efficient, consistent tankless backup for solar water heating. Previous other solar tankless backup solutions fed the hot line from the solar tank directly to the tankless backup unit, which would heat water when the temperature started to drop, which could lead to temperature fluctuations, the firm says. The RH360 kicks in only when the water temperature in the solar storage tank drops below a pre-set point, drawing the coldest water from the bottom of the solar storage tank to the tankless unit and returning it to the top of the tank, helping to maintain consistent-temperature hot water delivery, the maker says; minimal tank mixing allows for optimization of solar gain, and the elimination of off-cycle thermal circulation decreases heat loss. 866.746.6241. www.rinnai.us.
