    Cheapest way to use the immersion heater

    Cheapest way to use the immersion heater 12th May 05 at 11:04 AM
    We have a temporary problem with the gas powered hot water and heating. In the short term we are using the electric immersion for hot water.

    Does anyone know if it is more economical to

    leave it on all the time
    switch it on as needed
    switch it on for a fixed period each day?

    There are three of us with the usual needs for baths and a washing machine.

    Years ago a plumber told me it was cheapest to leave it on all the time so the thermostat only kicked in occasionally to keep it hot. He said it used MORE fuel to heat up water from cold every time. I don't know about these things so does anyone have any ideas? Thanks :confused:

    I initiated my own #126 thread, you have now wasted hours stalking me in my own threads because we differ.

    If you have the view that differs from mine or indeed any other person feel free to post it in your own hash number, its your view and its a free world.

    I could trying to explain the sequence of events starting with post #124. However I don't think you would understand that either - or indeed how a thread cannot be initiated after 125 posts

    The hot water cylinder should be Part L of the Building Regulations spec : ?
    Hi All

    Regarding: "The hot water cylinder should be Part L of the Building Regulations spec : ...", my question is why ?. My understanding is that hot water cylinders in existing dwellings are not required to conform to either Part L1B or Part L, it is only new work which needs to be compliant ..... am I actually missing something here, or is there some confusion on where/when Part L1B/L actually applies .....

    Perhaps this looks like an example of why public sector expenditure is so high , me, I've got a copper tank with no factory foam insulation and therefore not effectively part L compliant, however, it's double quilt insulated and sits in an insulated cupboard, total heatloss from the cylinder on a replacement heat fuel consumption basis (gas condensing boiler) is <2kWh/day (measured) which seems to exceed part L requirements on heat loss.

    You are correct - it doesn't. Upgrades to Bldg Regs are not retrospective to existing installations. New and replacement installations must, however, comply with Bldg Regs in force at the time of the installation.

    You could be correct.

    immersion heaters
    I have electricity only, thus have a water tank with electric immersion heater. am getting quite frustrated as it seems my water tank immersion heater is having to change every year!!! how long should this immersion heater's last? what is the best quality to purchase? I have never purchased one, as when I call for a plumber they come with the parts but its costing me too much.. The damn thing needs changing again!! I have been using the booster the last few days which I have only changed once in the last 5yrs but its not cost effective as electricity is expensive in the day time .. any suggestions please? need to sought this ASAP. - thanks

    Immersion heater elements should last at the very least 10 years. You shouldn't need to be replacing them every year. Make sure you buy a hard water type if you live in a hard water area. Also make sure the plumber is not ripping you off as newer immersion heater elements have a small trip switch/reset button on them which could just need resetting rather than having to replace the whole thing.

    Immersion Heater Boost
    Hi,

    This is a long thread so sorry if I am going over old ground. I live in a small flat which runs electricity only. I am very frugal with my electricty using Bye Bye Standy etc and also turn on the storage heaters when needed. (They spend the rest of the time off at the wall).

    However despite my best efforts I received a massive bill for some 600. Having previously paid 33 per month from September to March Incl. They say it's a catch up bill, but it seems a hell of alot.

    I am trying to find out what's drawing so much power. I looked at the boiler and found that both immersions heaters were on set to on.

    My question is what happens when you leave the top immersion element on all day (is it constantly on or just when the temp drops and water is used) and how much does this add to the bill a week.

    The boiler never sounded like it was blaring away all the time. Water used 2 - 3 showers a day, washing machine (though not everyday) and washing up.

    Thanks.

    Gustav - you will only have the amount of hot water that your tank can hold. Therefore, you either need to get a bigger tank installed (expensive), get a different way of heating the water (combi boiler, instant electric water heater - both expensive) or reduce the amount of water you use/ separate your periods of use so you can reheat the water between uses (i.e. one of you take a shower, then leave it 60 minutes with the immersion on before the second person has a shower). One compromise that seems to work is to get a new showerhead which uses less water. These are available on-line (we have one made by Mira) and work by introducing air bubbles into the water stream. In this way, you use less water and are more likely to get 2 showers from 1 tank of hot water. If you have a power shower, these use a massive amount of water, so you are unlikely to get 2 decent showers from one tank of hot water. We replaced our power shower because of this.
    Hope this helps
