Hello. There is a hard freeze warning for the Palm Beach, Florida area tonight. Temperatures are expected to drop below 32F. I have a AquaCal heat pump and I noted that it has a winterizing plug allowing you to drain the water. I read the manual and they suggest that light freeze can be controlled by just circulating the water through the pump but they suggest draining the system in any long term or hard freeze conditions. Any thoughts or true to life experiences would be appreciated. Personally I rather not touch any plumbing. I seem to have gremlins that cause leaks and such whenever I tinker with plumbing.
Thanks guys / gals.
