Hi Guy's just finishing putting in a new outside spa/ hot tub.
I am almost ready to fill it up.
My question is do I fill it up cold garden tap and let the spa heater heat up the water?
or do I
Fill it up hot from the instant gas hot water service?
any help would be great
I have seen professional pool installers use a fire hydrant. In theory it will work for a spa too? Wouldn't it be cheaper for your water bill? However you may need to treat and circulate the water until it clears up and has a safe ph level.
You can't just use fire hydrant water. IF you're filling up a pool you have to pay for the water that goes in it.
Yeah they probably have a permit to do it. Still might be cheaper than the garden tap.
cost of the water isn't a big concern its more the cost of heating the water up.
Are you on off peak rates overnight?
You could fill it up cold, turn it on at night and let it heat up - may take a couple of nights actually if you use this method
only single rate..
I am thinking of putting in a small solar system later on and having it only heat during the day
Your neighbours will prefer this option as outdoor spas can make a lot of noise.
Using gas will be cheaper and faster than heating with the electric spa heater. IT will take a long time to get to spa water up to temperature using that method.
Have a nice warm bath instead. Allot cheaper!
The Ozbargain method: wait for it to rain and redirect a down pipe to fill the spa and find a way to heat it with a fire
