I’ve recently bought the Lay-z Spa Vegas which is very good for the price. My only problem is the cost of heating it, it’s costing about £6 per day. Is there a more economical way to heat them? Just recently I tried keeping it on 35 degrees constantly and then boosting it to 40 degrees 4 or 5 hours before I wanted to use it but that didn’t really change the cost much. Any help appreciated!
