Lee get on ebay and get an 1 Kw aquarium heater would be better for you needs as L5 heater is more for an on demand usage . Mike
Thanks Mike.
Trouble is my ro-setup ia at my parents garage.
I suppose i could set up and put heater on timer plug.
How much is 1KW an hour Mike 10p.
How long do you have your heater on for.
Just add: I fill up barrels from 625 ltr tank at my parents has submersible pump.
I have 16 barrels; last 2 days usually; I dont have garden but do have garage en-bloc about 50 yards away.
Reason for barrels is parents don't have off street parking.
Sorry to waffle on Mike.
I will look into that.
My dad helps with my system, but he and my mum are in there 60's and can be a bit funny at times.
Did have a bust up with em few yrs ago just before setting up my system
So I do like to keep things simple at that end; "THEY FEAR CHANGE
