The heat-shrink can be heated with a heat gun or a simple lighter. Just heat it until it shrinks around the wire (you will see the sealer ooze out) then stop. Over-heating may cause any heat-shrink to become brittle and crack.
The #1 culprit in any wiring connection is corrosion. The heat-shrink on these connectors have a low temp solder that seals the connection completely and does not allow any moisture or air to get to the connection. The second culprit with other connections is vibration. These connectors work well in securing the insulation to the wire to eliminate vibration.
As stated by PopBeavers, soldering and heat-shrink is probably the best way to achieve a proper wire splice. Any crimp connection should be done properly and
traditional crimp connectors are not my 1st choice, especially in outdoor applications. They are subject to corrosion and vibration. However, these particular "heat-shrink" crimp connectors make a very adequate seal and I have used them in marine applications for 15 years (including a complete re-wire on a, very complicated, 45' yacht) and have never had an issue.
BTW........these heat-shrink connectors are also available for wire
end terminals. I wouldn't use anything else for wire 10G or smaller. Anything larger than 10g should definitely be soldered.
