Although gas is a lot cheaper, your combi-fed shower will be delivering a lot more heated water, so overall the costs will be similar. It's just that the combi shower will be a LOT more pleasant
And, yes, it'll also use around three times more water.
Of course, you can counter this by turning down the water flow to match that of the old leccy shower, and THEN you'd have savings. But, man, is it worth it?
If ALL you want to achieve is 'savings', then I'd have to recommendvsticking with your leccy shower, 'cos you SHOULD factor in the cost of any change; fitting a thermo mixer will cost £100's, and that would pay for a few year's worth of showering energy.0 -
I fully agree @Bendy_House - it's used more gas than I had guessed it might - well, largely because I had no idea how it would work, hence starting the other thread.
It definitely didn't use three times more water - my rough measuring of my foot (plug in, looked where on legs the water came to) would suggest about 25% more and I was in there a bit longer today. I probably could have increased the flow more, but it would have splashed off me more and made a mess.
I was largely curious to see if there was a genuine saving to be made - but even after one day, it would suggest not. It would take a long time at 12p per day to recoup the installation cost.
But I still have my daft hose, so will do a bit more experimenting for a few days and I still have the option to use it when I want. I think I'll restrict my investment to a few quid for some suction hooks to hold the hose out if the way.
There is a strange phenomenon though. I'm also monitoring my electricity usage, as I'm switching my computer off overnight, which I never have. So taking my meter reading this morning, I'd used more than I was expecting. But I had switched the electric shower on, just in case of mishap when I was all lathered up. So that might have added some to the electric use, or the hot water pump in the boiler uses more than you think. This appears to have negated any heating water saving I might have made. It'll take more than one methodology-flawed day to come to a definitive conclusion.1 -
Your electric shower - as you'll know - will be the single biggest consumer of leccy in your house, by a country mile. So even LOOKING at it will consume more than a PC left on standby overnight.0
