Default Oil filled radiator help please

We are moving to a new flat which has no central heating!!! only a fire in the lounge. I was looking at buying three of theses for the two bedrooms and the bathroom.

http://www.froogle.goshopdirect.co.u...f80a27915c5442

they are 2kw, does anyone know if that will keep us warm, there is single glazing for now but I will get thermal blinds (advice also gratefully received) and lined curtains at windows and doors.

Also the running costs of this, would they be silly high during the winter and is there a better way to heat the flat for now.

There is no more expensive way to heat; on maximum setting these will cost approx 20p an hour to run.

They are slow to heat up, but slow to cool down as the oil retains heat, which can be an advantage of disadvantage depending on how you use them. A fan heater will produce instant heat(at the same price to run) but of course when switched off there is no heat.

Be very careful about using any electrical device in a bathroom.

I would go a lot further than that - DON'T use ANY mains electrical equipment in a bathroom - except an electric razor plugged into a proper bathroom approved shaver socket.
If you want heat, get a qualified electrician to advise and fit for you.

I have a 1.5 kw heater like that and I love it. I am using it in the kitchen now because I do not want to heat the whole house (not cold enough yet). I plugged mine into a timer so that it comes on before I get up.

Default Heating Costs

I have today obtained heating costa from EDF Energy as follows

A 2KW Oil filled radiater 30 mins warmth for 1 unit

Fan heater 2KW 30 mins warmth for 1 unit

Covector heater 2KW 30 mins warmth for 1 unit

Infra red heater 1KW 1 hours warmth for 1 unit

Panel heater 1.5 W 40 mins warmth for 1 unit

Radiant heater 3KW 20 mins warmth for 1 unit

Find out what you are being charged per unit from your supplier and you can work out your running costs

The problem with those figures is they make the assumption that the heater is on maximum setting and the thermostat is not operating.

In practice they will be switching on and off as the set temperature is reached.

The point to make is that for the same running cost, all of them give out exactly the same amount of heat.

I think the OP was looking for a bit more than the obvious. The figures quoted are obvious...1 kw of warmth for 1 hour is 1 unit for any system so infers that costs of heating a space are the same no matter what heater you choose. We know this is not true. The REAL point to understand therefore is this...What heater most effectively heats the room for a given amount of power. I.E. Is a 1 kw electric bar fire as efficient at heating a room as say a fan heater, or an oil filled radiotor etc etc. The most efective heater for a given space can be used less or used at a lower setting for the same effect thus reducing running costs.

So having said that, I am also looking for a good single room solution and would love some advice on the most effective heating to use.

From personal experience I can say that not taking into account the cost Delonghi oil filled radiators are very effective in warming up rooms. We have a house in France with no heating except for the oil filled rads which actually enable us to stay in the house even with it being -9 outside.

There is not much difference in those, because it's all electric, and all 100% effective. They have other differences tho. Fan heaters give quick heat, but they heat air, just like call convector type heaters. Radiant heaters, like those free standing glowing heaters are heating objects(e.g. a person) rather than the air. Oil heaters heat up the oil slowly, and it retains heat for a while(I see no reason for this). But you get always the same amout of heat every time for certain amount of money.
Termostats can help you a bit by turning on/off the heat, so you don't get too cold/hot, and it's "kinda" saves you money.
Effectiveness can be increased by strategically placing these product to particular locations in the room, so there is air circulation, but I can't tell you much about it.
I prefer a cheap convector heater, because it's not glowing, quiet, safe, and relatively small. It heats the air, and in time air heats objects.

Sorry but what your saying isn't true. Firstly all heaters will heat up air, how can the heat not get to the air? Although it will heat up a person in close proximity more due to the low surface area of the heater.

The point of an oil heater retaining heat is, it doesn't require constant heating. Normal convective heaters heat up a heating element that gets hot (like a kettle) an then the air passes over the fins and warms up ... The heating elements lose heat quickly and therefore require constant heating. Oil however does not lose heat as fast and so the heating can be paused until the oil drops below a certain temperature therefore requiring less electricity per hour.

Hope this helps.

Hi, we bought a Swan 2kw Oil filled radiator last winter to supplement our horrendously expensive oil central heating. We love it, so much so that we have just bought another.

We have quite a decent sized lounge and the oil radiator heats it perfectly with the door closed. We didnt notice any particular increase in our electricity costs after using it and the thermostat clicks it on and off which saves a bit of money I suppose. It has a very low setting which is ideal as a bit of background heat. They do take a bit of time to get warmed up but this isnt a problem. Ours has a timer on it too which we never use but could be handy if its your only heating.

We also have a fan heater in our small study which is great for a quick blast of heat but its quite noisy. I would choose the oil radiator every time.

I bought a small 2kw Delonghi oil filled radiator for my small office when I'm working at home during winter, I also use it in the attic over night when the temps really dip (have a fear of burst pipe running down over three floors ) may sound a little extravagant, rather pay a little more over cold periods!!

Oil filled rad is ideal for my applications, on/off when required via stat.

The original thread is almost 5 years old, so hopefully the OP has warmed up by now. But the facts dont really change much through the passage of time, although the bills probably have (upward)

Electricity is the most expensive form of heating there is, in real terms. As indicated on this website

http://www.biomassenergycentre.org.u...88&_dad=portal

I use a modern, Japanese made Paraffin fan heater. Has all of the latest safety features, probably more so than the average portable gas heater. It burns paraffin at 70p a litre, and I get around 10 KW/H of heat from 1 litre of paraffin - so 7p per KW/H - far cheaper than Electricity.

The manufacturers also claim a 99% efficiency rating, largely due to it being completely flueless (no heat to escape through the vent / flue) making it 'almost' as efficient at turning fuel to heat as Electricity.

Its fan assisted 3KW output heats a living room from cold very quickly, after which it falls back automatically to 800W output. Its extremely quiet in operation.

It only draws 22W from the mains, so around the cost to run in Electricity as a large energy saving bulb.

Ye gods, nows theres a blast from the past "paraffin heater" as kids we had one in the bathroom, was the only room up stair where you did not need to scrape inside of window to see outside during darkest winters!!

LOL, my Grandfather used to have one in the outside toilet as well, to stop it freezing up.

Fortunately technology has moved on a lot since those days, and these heaters are state of the art, very efficient and dont suffer from the same level of smells and water output as the old fashioned type.

Surprisingly, Paraffin / Kerosene is still the first choice of heating in many Japanese homes where central heating is virtually unheard of, hence where these heaters are designed and largely used.

http://en.wikipedia.org/wiki/Kerosene_heater
http://www.kt70.com/~jamesjpn/articles/heating-homes-japan.html

I reckon as Energy companies continue extracting urine from their reluctant to complain UK customers with similar regular rises to that which we have seen lately more people will have no choice but to resort to using the same methods of heating as our grandparents did.

At current rates. To run a 3KW electric heater in the daytime would cost me 57p per hour. To use the 3KW Paraffin Heater costs just 21p per hour. On a 5 hour evening thats 1.05 in Paraffin versus 2.85 in Electricity, and that 1.80 per night saving is much more at home in my Bank than Npowers!. The 1.80 saving per night, means that the cost of a heater is effectively recouped in 111 nights, thats around 1 Winter season!. If you find one second hand, it will probably pay for itself in fuel savings in less than 1 month.

In addition, If national demand for Paraffin rose to the point where it was 30 years ago, it could just be possible to buy Paraffin in bulk for as little as 30p a litre, and with these heaters that effectively means a 3p / KWH cost to heat rooms, which makes it less than the cost of Mains Gas, whilst at the same time being more efficient at producing heat than gas at 99% , and with lower servicing costs (just change the wick / catalyst every few years and clean the fuel filter every few months). Makes you wonder whether we can't learn a lot from the Japanese eh?

You surely cannot be paying 19p a kWh for tier 2 electricity?

Even British gas standard tariff is only about 12p/kWh and under 10p/kWh is obtainable.

No, it doesn't help.

You have said Soneyboy was incorrect when in fact what he said was 100% correct, and what you said was a load of nonsense.

Why do people do that?

Although it was 10 months ago, and it was the first and last post, many of these people either have a vested interest or have bought a radiator filled with a 'magic ingredient' and are just repeating the sales blurb!

Well E7 unfortunately!.

Check out Npowers E7 Prepayment rates for Midlands area. Currently 5.334p for E7 and 18.857p daytime rates.

Yes, it is E7, and yes I do have ancient storage heating, however its so inefficient in the old farmhouse i'm in, that I only class that as background heating, as last winter although warm enough to have breakfast in, they only managed to maintain a living room temp of 16c tops by mid evening in the living area, so some Daytime Electricity input was required for anything upto several hours in the evenings. At 17.52p (then) and 18.857p (now) its quite expensive, certainly more so than the 7p which I get from the Paraffin Inverter.

My bedroom is also over an open carport, effectively no room underneath and outside air circulating just inches below the floorboards. I dont have to tell you how inefficient the 2.55KW storage heater is at warming that room, and basically does nothing, fortunately I get up for work at a time where I can have a 3KW Fan heater on a timer and still take advantage of E7.

No storage heater in the bathroom, just one of those 750W heat 'n' light units which again, is totally inadequate. A quick blow through the door of the inverter and at least its warm enough to shower in.

Supplier and meter type is controlled by the landlord, i'm unable to change supplier or change to a credit meter. As I've said on other posts, I doubt he could have found a more expensive provider if he'd tried!
