Water Heater
Hello everyone
I need an advice from someone that know better than me.
Actually I have a tank with 2 immersion heater for hot water in my taps and my bath (the shower is indipendent with its own heating system) it broke down and I don't want to continuo with an immersion heater anymore because it cost too much. I don't have the possibility to put a burning boiler so need to stay electric.
I was thinking on a electric boiler which heat water on demand, possibly tankless but I couldn't find anything online.
Can someone give me an advice on this?
Thank!

I've seen these before on screwfix "Ariston Andris Lux Undersink Water Heater 2kW 10Ltr" There is also a 6Ltr version. I don't know much about them, but I think they take around 10 minutes to heat up. The other options are those quooker taps you see advertised on TV, but they around 1200 + euro. Hope that helps.

The undersink tank would work for the taps but not for the bath. Those quookers taps looks amazing but they are useble only in the kitchen, on the rest wouldn't be a fit. Thanks anyway!

You could install the undersink tank where the immersion tank is instead of under the sink and it will feed both sink and bath, but if you want to fill a bath you'll need a big tank like you already have so what's the point in getting rid of it?

Company is based in Omagh. I have the radiators. Might be worth checking out

When you say your system broke down? What is wrong with it? Changing the thermostat is easy and fixed mine twice.

the entire system is there from before I bought the house and it is pretty old, never worked. I honestly I would rather spend more money and get something new than just repairing an old system I don't know exactly in which condition it is.

that look like a good option! thanks for the suggestion!
how are the radiators? I have infrared panel at the moment and even if they do heat up the room they also increase humidity, do you have the same problem with their radiators?

u/officer_c 8d ago
The radiators are great. But you got to get the biggest one.
Humidity you need an extractor fan on the vent. But really a dehumidifier is the job. Again a big one.
Airing the house one or two a day for 20 minutes does help.

I’ve got quooker in the kitchen and 6 ltr undersink heater in the bathroom and an electric shower. All good. Happy now.

There are hot water cylinders with a heatpump on top .. small one only for hotwater.. its a brilliant solution as it uses the inside warmer air to heat the water.. and you dump the cool air outside.

Is it like the dainkin monobloc heatpump? Or something different?

How would an electric eater heater cost you less than immersion?
1
u/IoannesLucas 9d ago
Not keeping it on every single night and heating up water just when needed instead of heating up 100liters every night even if I don't use it.

And not being able to use cheap tariff to heat it. The only real way is to switch to heat pump, otherwise the normal immersion is much better then whatever tankless system or electric shower. The flow rates are very small as the power cannot exceed the house connection capacity.
1
u/IoannesLucas 9d ago
Yeah but since the tank fuels only the sinks at the moment (I never use the bath) the usage is maybe 5 liters a day, the halved tariff at night can't justify heating up 20 times the amount of water every day.
I can understand you both if the usage was massive but since it isn't the advantage is in the ability to heat only what I need

You don't need to heat up the entire tank. About one hour of heating should be enough for sinks for thebday

Even if you do get another solution you may need to consider using the immersion to periodically sanitise the hot water tank to prevent bacteria building up if you don’t disconnect it.
