A short self-regulating cable with a thermostat, for one gutter run or a few pipes. Buy clips separately for roof use.
Amazon $62.99Under $150 covers longer cables and complete kits, enough for a long eave, a long water-line or a full gutter and downspout run. This is where you find self-regulating cable with a thermostat and a power cord ready to plug in.
Work out the total length before comparing prices, since cost per foot is the fairest measure. Check the circuit load against the cable’s wattage, whether the cable is rated for roofs or only for pipes, and whether replacement lengths or end kits are sold. A plug-in cable needs a nearby outlet, and a hardwired one needs an electrician.
