Leaving the immersion on

lazygal

Just realised I left it on this morning. How much will it cost me for the day?

Not that much.

Once the water heats up, the immersion should auto cut off, and then only turn on to keep the water warm every so often.

Edit:
Unless you live in a dive with an ancient immersion.

Very little as long as nobody is using the hot water.
Works on a thermostat so will only cut in and out to maintain a temperature...
Some people I know leave it on the whole time...... thinking is it takes a LOT of electricity to heat water from cold, but less to maintain a constant heat

Will anyone be using any hot water while you're gone? If so ask them to turn it off.

Otherwise I would say approx. €1per hour for the first couple of hours until the water heats up then approx 20c per hour thereafter.

No one home until tonight. At least I know I can have a bath with the hot water. Have the immersion fear in me though, thanks Irish parents.

I've often wondered why they call it an immersion. It's basically just a giant kettle wearing a coat.


(It's probably something simple like "because the heating element is immersed in the water".)

Mr Benevolent

The pressure will build up when the immersion is left on, eventually leading to a mini Fukishima. Get the radiation suit out, OP.

Phew, tank is well insulated (thanks dodgy builder who owned the house before me). So not too much. Why are people so fearful of leaving it on then?

I'm a married woman. My husband will take it out of my housekeeping money.

PM me and I'll fit a push button timer for you. Push once, wait. have shower and don't worry about turning it off again.

Also might give your plumbing a good service if you're good looking.

Ring the neighbour and tell him to kick the back door in and turn it off. The cost of the door repair can be off set with the 3 euro cost saved on the immersion.

If you do live with a crap immersion, be prepared to pay for the walls to be stripped and re-painted. We left ours on before resulting in steam coming out somewhere in the attic and it coming down over the walls.

Not only did I grow up with the immersion & lights left on in rooms fear - we also had the OVEN one - she'd actually knock up a few cakes, tarts, bread to bake if a roast was being done to make full use of that heat?????

That sounds fcuking awesome. Why are you questioning it?

yeppydeppy

I used to leave my emersion on the whole time and it only added slightly to the ESB bill. I stopped doing it - I'm not really sure why. I have an electric shower and I live alone so there isn't much need for a tank full of hot water. I suppose if I had someone coming to visit I'd leave it on.

I do that too-no point in having the oven on for one roast joint when you could have an apple tart or scones and roast spuds cooking as well.

Because of a racial memory of a time before thermostats!

Even for the hour alone, that's about 15 quid a month.

thejournal.ie have repeated this advice today. i've asked plumbers about this before, and have been told it's an old wive's tale.

if you leave the immersion on constantly, it's constantly losing heat to the surroundings (albeit much reduced with a modern well lagged tank); so in that scenario, if the immersion is operating in 'top up' mode with no water being drawn, you're basically just paying to pump heat into the surroundings, as well as then for the water you use.
but if you turn it on as needed, you're just heating the water you intend to use.

kneemos

We have small water heaters which hold about four or five gallons,not enough for a bath but plenty for a shower and the taps and doesn't cost much to leave on.
