  • Better alternative to heat tape for downspouts
    This year I fished two runs of roof melt heat tape through the downspout This works when the weather is not very cold, stops working bellow -10 deg C (14 F), which is where I need it to work It doesn’t put out enough heat to melt the ice, just enough to allow it to drain It is also a huge energy waste (~10 kWh day)
  • What type of tape can I use around pex pipe? - GreenBuildingAdvisor
    Hello, I am looking for tape that I can wrap around my pex pipe, where they go through the studs It get's a bit chilly in the winters and want to protect from any potential condensation on the wood Pipe insulation is the obvious, but I would prefer to stay with smaller holes hence the tape I have read from several sources saying that heat tape should not be used on pex pipe, although I am
  • Alternatives to Heat Tape for Preventing Ice Dams

  • Insulated well covers that won’t need aux heat for zone 4?
    Are they buried or in conduit? If the are in conduit it is probably large enough to accommodate another 2-12 wires Just pull a couple more wires and place an outlet for heat tape Just build a very small doghouse like structure with lots insulation and the heat tape will probably come one very rarely if at all Insulate the pipes themselves as
  • Minisplit Heat Pumps and Blizzards - GreenBuildingAdvisor
    A blizzard (a severe snowstorm and sustained winds of over 35 mph) is a challenging weather condition for a minisplit heat pump Recall how an air-source heat pump works: the outdoor unit has a compressor and a fan that blows air across a coil with refrigerant In heating mode, the coil is colder than the outdoor air As air is drawn through the coil, it gives up heat to the coil and leaves
