You should leave the heating on all day, rather than turning it on and off. Turning the thermostat up will heat the house up faster. Will this cactus protect you from damp? Find out below It takes more electricity to turn lights off and on again than to leave them on.
Dishwashers use a lot of energy. Cavity wall insulation will make my house damp. The cavity is there to let the walls breathe. The stuff stored in my loft is providing a layer of insulation. With warm air heating systems, you should put a bowl of water in front of the vents to stop the air getting too dry. Getting double glazing is the best thing I can do to keep the heat in. Getting solar panels will mean I never have to pay for electricity again.
LED lights can cause blindness This myth has been in the newspapers, but light from LEDs is not intense enough to damage your eyes. Energy suppliers are all the same so there's no point switching. I have been with my energy supplier for years, so they are probably rewarding my loyalty by giving me a good deal. Getting a cactus will make your house less damp. We heard this one once.

If you heat water with an electric immersion element only, you should consider installing NightSaver electricity and heat the water during off peak hours night saver meters are free to install, but will cost you money if you decide to revert to a regular meter.

In the Summer we have lovely hot showers but in the Winter when the heating is on the showers are Luke warm! I have to manually turn the boiler on as the control panel has broken so I am therefore unable to set it to come on early in the morning. Would it be more cost efficient to leave the boiler on all night but turn the heating off or put the emmersion heater on when I go to bed.
Thank you! I have to switch it off from the circuit breaker. How can I correct this does it have to do with the thermostat on top of the immersion element , if so what should I do to correct it thanks. Marcia the light you are referring to on the switch on the wall adjacent to the immersion heater, if it is then it sounds as though your switchfuse is faulty and will need replacing. I would suggest you contact a competent electrician to get it tested and if necessary replaced.
Hi Good post with logically flown thoughts on using immersion heater! I have 2 kw solar panels and with the summer setting in I will have output from them more enough to run other devices probably another immersion heating tank itself! Now we have switching devices in the market that can manage the excess power. Does anyone have it and how is it performing? You will need something like what John below is using. This is normally measured and switched much faster than the individual half cycle length of the mains supply which is 10mS, so we are talking around every uS!
Power is switched for a fraction of a half cycle at a time in order to manage a 3kW load!! I too have 2kW of solar panels and had them for over three years now. I recently came across articles about automatic switching devices. There is a wireless transmitter fitted adjacent to your electric meter that sends information to the Solar iBoost. It then switches on the immersion whenever the generated solar power is over watts, so all excess power goes to the immersion.
It is great, even on a resonable sunnny day I get a tank full of hot water. I still leave on my hot water cycle on the gas fired boiler, but this now comes on early morning but as most days the tank is hot from the previous days solar input, it rarely stays on for long. My one bedroom flat only has an immersion heater, no boiler. I work full time Monday to Friday and only need hot water for a couple of hours after work each day pm.
I had it on for two weeks straight without realising the potential cost so have now turned it off and will only switch it on for a couple of hours when I get home each night so I can wash etc. Another query which is linked to the above is that my flat has storage heaters which i think must run from the immersion heater?
If so is there no way of having the flat warm when u get home without leaving the immersion on all day? Thanks in advance. From what I can tell, you have an immersion heater to produce your hot water and then storage heaters to provide your heating. They charge during this cheap period — and the electricity is used to heat bricks and the theory is that this heat is retained until it is needed within the heater — hence the output dial on the storage heater, this sets the rate at which the heaters give up their heat once charged.
The main issue with the older storage heaters is that by the time you want the heat, it tends to have leaked out, which means you need to recharge them. In terms of the immersion, again this runs off electricity. Based on the fact you are on economy 7 am I assuming that based on the storage heaters , you should definitely heat the hot water during the night — maybe from 4am — 6am. This means that it will cost less to charge because the electricity is cheaper.
This should provide all the hot water you need for the day to be honest if the hot water tank is in anyway insulated.
If you then need more hot water, just flick the immersion on for an hour or so. Hi, I just moved into a property and amount of electricity my boiler is consuming is huge.
Am spending about 10 pounds a day. Is there any way you can help me to save a bit. This is not a great idea! Find the plug for the immersion and switch it off! You only need this on for an hour or so to heat a full tank of water. Keeping it on all the time is like continuously boiling a kettle. After that you are going to need to give us a bit more detail — electric boilers are very unusual.
You normally get gas boilers with hot water tanks that have electric immersion backup. If you have no electricity in your home then yes — the immersion is going to be producing your hot water but ideally this should be put on a timer so it comes on for just a couple of hours a day to help minimise your energy bills!
The tank our builder put into our new house about 10 years ago only seems to be very poor only having about 25 mm of insulation on it and the inside of our airing cupboard was always very warm. Firstly I have covered all the hot pipes with foam pipe insuation cut with a sharp kitchen knife and mitre the corners on pipe bends for a neat job occasionaly held in place with insulation tape. I then bought a 75 mm tie on foam jacket from screwfix — it is in six panels so that you can allow for pipes.
Do NOT cover the immersion heater but take the insulation round it. So my tank now has mm insulation and now only a warm, but not hot airing cuboard. A well insulated storage tank will loose about 2kw per day, or about 30p although perhaps poor plumbing might increase this.
Then there is the question of thermostat settings. My advice would be to set the thermostat so that the water is actually a little too hot. That way you can start to collect the initially cold water, knowing that the following hot water will bring it up to the temperature you actually want.
And one final point. When comparing relative costs, I assume we are talking about town gas because LPG is considerably more expensive. Hi I have recently put my electricity metre readings into my energy account and had a massive shock with the amount I have been charged for my electricity. I live in a rented flat and there is no boiler only an immersion heater. We had it on continuously for six months without knowing how much it costs.
I have read the information provided here and I understand putting a timer on the heater, is there a timer already fitted to the heater or do I have to purchase on?
Also how long does the water in the tank stay hot for if I let it heat up for an hour or so? Me, and a couple with an 8 months baby have just moved into a property which has both boiler and immersion. Also, the master bedroom is en suite and the shower has a pump which gives a really good flow of water. The problem is when we use the boiler to heat up water, hot water is available everywhere else, but not so in the en suite.
The second issue is that in order for the central heating to operate, we have to switch on the hot water as well. Does this make any sense, because in all other properties i have been the hot water and central heating were operating independently. Hi, my flat which is privately rented has an electric immersion heater only as no gas supply.
The pipe overflow? Our rented house has a hot water tank with an immersion heater.. We have no gas in the house. There is a back boiler connected to the old solid fuel Rayburn range, which. We do not use the stove the rest of the year. Is there any way we can reduce the price of our hot water?
Hi, Am looking at moving into a flat with an immersion heater no gas and what I thought would be a storage heater but now believe it is not storage and economy 7 would not be useful.
In fact E7 is not installed. What is the best way to use these? Would we need to request a Plummer to come and look at it? Any help would be good. It is so annoying that everything in my flat is electric including the immersion to heat hot water.
Hi David, have you tried insulating your tank? In addition you need to put your immersion on a timer — a 3kW immersion element will cost about 40p to run each hour and 1 hour should be sufficient to heat a cold tank up to temperature. I would therefore suggest running this just for an hour in the morning and an hour in the evening — bringing the cost down to just 80p.
Getting a basic timer on the immersion would allow you to set this up rather than having it running all day unless you are happy to do this manually. I only have an immersion heater, no boiler. So I use it to provide my hot water for baths and hand washing.
We have an electric shower so this works independently. Our immersion is thermostatically controlled so it will never boil all night. When it reaches its temperature it turns off. I am adding solar panels, giving me free electric in the day. I have a standard gas boiler and an insulated HW cylinder with top immersion heater.
I prefer a combi boiler, but plumber has said the standard is more efficient to run underfloor heating, and if I get a new cylinder with bottom immersion, I can heat water free in the day. I think this is a waste, and am thinking of localised hw heaters at sink and shower. Is this a good idea? If I keep the existing inefficient cylinder and boiler, both only 4 years old, then I have saved a lot of money in new equipment. I put my immersion on last nite as ran out of credit on my metre 3 hours later the water is freezing anything i could check myself before I call someone.
Hi Kelly, Do you mean you ran out of gas credit? The immersion should produce a tank full of hot water in hours depending on the size of the tank and how big the immersion unit was. My son lives in a rented flat with night storage heaters and an immersion heater, he is a single lad out at work all day but with everything being electric his bills are very high, he has a shower which required the immersion heater to be put on every time, would an electric shower installed be cheaper to run.
It has a timer on it but i have no idea how to use it.. The switch is on if it is in at the bottom. The heater is on if the light on the switch is on. The heater is on if there is a noise coming from the tank. There is also an expansion pipe because as water heats up it expands and needs to be returned to the cold water tank. There is either a switch which when you turn on turns the immersion on or they are sometimes on a timer — if this is the case there should be clock somewhere near the immersion unit that you can then use to dictate when the immersion heater comes on.
I have just moved into a property which only has electric. Is this necessary or is there another way? This tends to be for when you are on an Economy 7 meter — i. What happens is that the two immersion elements are using the two different rates.
I would also empty your fresh water tanks as well. Should I leave my immersion heater on all the time? Category: home and garden home appliances. It's better to leave the hot water heater on all the time , rather than turning it on and off.
Your immersion heater or boiler will heat up hot water which is stored in a tank. As long as the tank has a good insulating jacket, it will keep the water hot all day, without needing to be constantly reheated. Is my immersion heater on? Is it cheaper to keep your hot water on all the time? How long does water stay hot in immersion heater? What temperature should I set my immersion heater? Are immersion heaters safe? How much does it cost to run a watt heater for 24 hours?
