The main advantage of having an immersion heater is that it’s separate from your boiler. This means if your boiler breaks down you can still generate hot water for your home.This means that when the water reaches the desired temperature, the immersion tank will automatically turn off, so you aren’t wasting money.
How does a boiler and immersion work?
A gas heated water tank is fitted with a burner underneath that helps it to heat water. Conversely, an immersion heater heats water directly inside it. Here, there is a heating element immersed in the water, and a strong electric current is passed through it which causes it to heat the water in contact with it.
Why do I have a combi boiler and a water tank?
One of the many benefits of a combi boiler is that you don’t need a separate water tank to store hot water. A combi will only heat water as and when it’s needed, making it an efficient and practical solution.Both of these options allow hot water to be stored and used later.
What is the difference between a boiler and immersion heater?
Boilers: they can be natural gas or fuel oil. They serve both for heating the house and for hot water.They provide hot water only. Immersion heaters: they work with electricity and provide hot water only.
What does immersion mean on a boiler?
Immersion heaters mean you can still get hot water
On top of the hot water tank is an immersion heater. This is nothing to do with the boiler; instead it runs on electricity directly and essentially acts as a huge kettle.
Does an immersion heater use a lot of electricity?
Heating water using electricity is more expensive than heating water with gas. A typical immersion heater uses three kilowatts of electricity an hour, so it will cost the average house about 50p an hour to run.
Should you leave immersion heater on all the time?
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.
Can you have a combi boiler and an immersion heater?
A combi boiler will provide hot water, as well as heating and will save you money in the long run. It will also take up less space than a traditional regular boiler and you can always install an immersion heater as a backup.
Do you still need a water tank with a combi boiler?
Combi Boilers
A combination or ‘combi’ boiler is both a high efficiency water heater and a central heating boiler in a single compact unit. Combi boilers heat water directly from the mains when you turn on a tap, so you won’t need a hot water storage cylinder or a cold water storage tank in the roof space.
Are combi boilers being phased out?
There are no plans to phase out gas boilers in existing homes. That said, the government may encourage more of us to ditch gas in favour of alternatives. Using grants or incentives for insulating our homes or installing low-carbon heating.In time, it’s possible there could be a complete gas boiler ban.
What happens if you leave the immersion on?
The main problem with leaving an immersion on constantly is that the immersion thermostat will be constantly switching on and off. After so many hours the thermostat will give up, causing one of two problems. Problem one is that the immersion will not work.
Is it cheaper to leave the immersion on all the time?
1. Switch on as required. This topic comes up in discussion forums all the time, but it is not cheaper to leave the immersion on all of the time, rather than to switch it on and off as required. Even with a good lagging jacket, the cylinder will lose heat and cost more to reheat the water to the optimum temperature.
Will my immersion heater heat my radiators?
Immersion heaters will only work to provide your home or property with warm water.One of the biggest advantages of immersion heaters is the fact that they are separate from your boiler. This is why they cannot heat up radiators on their own, but they do give you some backup power should your boiler stop working.
How expensive is it to run an immersion heater?
Immersion heaters use electricity to heat water, which is considerably more expensive than gas. For example, 1 kW of gas will cost you around 4p, while 1 kW of electricity will cost around 15p. That means a 6 kW immersion heater would cost 90p an hour to operate, substantially more than operating a gas combi boiler.
Are immersion heaters thermostatically controlled?
Whether the water from an electric immersion water heater is too hot or too cold, it can be easily adjusted as it is thermostatically controlled.
How long does an immersion heater last?
between two and three years
An immersion heater may last for between two and three years before it burns out and needs to be changed.
When should the heating be turned off UK?

Why is my electric bill so high?
One of the main reasons your electric bill may be high is that you leave your appliances or electronics plugged in whether you’re using them or not.The problem is, these devices are sitting idle, sucking electricity out of your home while waiting for a command from you, or waiting for a scheduled task to run.
Why is my immersion heater overheating?
If the hot water is too hot, there’s a likelihood the cylinder is overheating, most probably as a result of the immersion heater thermostat not shutting down.For direct cylinders where the water’s ‘scorchio’, the unit may have been incorrectly wired. You’ll need to correct the wiring errors to fix the problem.
How long does it take for an immersion heater to heat a tank of water?
1-2 hours
The immersion heater is connected to the mains electric via a cable and has its own on/off switch. When the heater is turned on, electricity heats the metal element and this heat passes to the surrounding water. It can take 1-2 hours for the water in the cylinder to reach your desired temperature.
Should the immersion be on sink or bath?
How does an immersion switch work? To further reduce the costs of running the immersion, you should set it to the sink switch for quick showers. The immersion heater has two switches: an on-off switch and a sink-bath switch.
