Hot Tub and Octopus IOG

[Ste-EVo]

Ok, ok... i'm aware of the 'council sex pond' jokes etc but still considering getting one. However, I feel I may regret this topic

Looking at getting a Layzspa Helsinki, tbh we have for a while, but the running costs have put us off. However, I've been reading a little but about running it to keep hot during the 'cheap hours' on our Octopus Intelligent Go EV tariff (2330-0530 7p pkw) and it would appear at least, that people are saving a a fair chunk as opposed to running one on a normal tariff.

So my questions:
Have any PHers done the same and you thoughts on it?
What are your monthly running costs for similar?
Are you able to provide an example of previous/pre EV tariff against running it on an EV tariff?

If there is a thread on this then please point me in the direction, I searched but couldn't find one.

TIA.

I do exactly that.

Heat it every night during the cheap hours. If I then want to go in it turn it on a couple of hours before going in as it has typically lost a degree or so.

Used twice a week average £35-£40 a month.

ETA - ours is a proper one not a LazySpa. LazySpa in my experience are nowhere near insulated as well so it could lose 5-6 degrees through the day.

I have an older lay-z-spa Paris and pretty much do what you suggest. I don't really notice the additional electricity because I only run it from about March to October and lose around 3-4 degrees a day with a thermal cover. That works out at about 28p a day running costs if I keep it at 40 degrees plus maybe an hour or two to top it up on the days I'm going to use it.

As the Paris isn't WiFi enabled, I bought a module off eBay which I connected inside the heater egg. This allows me to set schedules to only heat during cheap hours and as I only use it at weekends, i also turn the temperature down to 30 between Sunday and Wednesday which gives further savings.

I reckon in total I am heating for about 20 hours a week at most which works out less than £15 a month including the pre use top ups. Much more economical than a standard tariff.

I've a foam walled one, heats up to 40deg overnight, at 5pkwh, only looses 1 or 2 deg in the day, comes on for 2 hours overnight, 2kw heater so about 20-30pence per day to run, under £5 a month.

When in put my lazy spa up I put a board of kingspan or celotex insulation under it - I think this makes it lose less heat .

[RotorRambler]

I was thinking of getting one of the foam walled ones also. IOG tariff.

In my head I was going to use normal tapi plug schedule, hadn’t realised that this isn’t always possible. So will ensure that the times can be controlled in the LazySpa own system.

Thanks for the replies so far.

Ive been reading that kingspan underneath is a good idea for preventing thermal losses. Im presuming 100mm?

Ive also bought some foil bubble wrap for the lid
