How safe is it to use a SSR to control power to a spa? Or use a relay?

These guys know how to play hard ball so make sure you know what you are doing.

I know exactly what I am doing.  I live in California where earthquake insurance is very expensive.  That's why I keep a gallon of gas on top of my natural gas hot water heater.  Should their ever be a large earthquake that would damage my house the fire insurance will cover it.

maybe, or the isurance will say the fire was caused by the earthquake and not covered.

Louis Rossmann has told several times about his business insurance refusing to covers loss from not having electricity,
because they didn't cover flooding and the missing electricity was caused by a flood at the powerstation

California law is if the fire happens after the earthquake you are covered by fire insurance.  If the fire happens before the earthquake you are not covered.

Really?  Can you tell me where I find that law?

You can intercept the low voltage signals that control those, or you might look at upgrading the control, I'd expect there are models available that can be programmed to run during certain hours. Mine has an "eco mode" that only heats during the scheduled filter cycle and that can be programmed to run at a specific time and it's pushing up on 30 years old so nothing new there.

James_s  - Thanks, I gave that some thought.  All of the relays are mounted on a circuit board and there are four different clean, heat, filter programs.  Just way to complicated.  Far easier to just install a high current relay after the GFCI and interrupt the mains power to the spa.  The spa's circuits have memory so the temp and other settings will all remain the same.  (I had another spa where the settings were not retained on power loss.)

In looking at posts in other forums getting others are doing exactly the same thing I am doing for AC units, electric heaters, pool pumps, electric hot water heaters etc.

Not sure if you read my other post, but the power company will change the amount of money they charge for a kWhr 5 times today for $0.12 to $0.54.
This $10 relay will save me over $1,000 in just 1 year.

Why would you think fire insurance would not be valid after and earthquake.
Why yes I can.  Goes back to the San Francisco earthquake and fire in 1906.  And was again re-affirmed with the 1989 earthquake and fires.

I wouldn't buy any electronic part that matters from Amazon.  Heck, I recently received Energizer CR2032 lithium cells from them that measured 2.7-2.9V across the board, pack of 20!  I discovered this after they went dead within a month when they should last 6-8 months.  Garbage.  Ordered Panasonic ones from Mouser; a touch over 3.2V across the board, priced $.23 per cell, qty 1. The Energizers were probably counterfit since any legit lithium cell should have a shelf life well over 10 years.  My best guess is they were really alkalines.  Just avoid.
