Most efficient electric heaters?

I was looking for similar solutions and sadly found out that the only thing to reduce energy bill is to insulate as much as possible. So went for the cheap option of plastic layer on windows and garage door insulation and after comparing the figures, I've used about 40% less energy for the past few months compared to last year. So I guess with proper insulation could be even better.

Storage heaters are pretty efficient. Those little 3kw blower heaters cost a bomb to run. 

Again, it's not as simple as that.  They're both as efficient as each other.  Storage heaters can be cheaper to run if they can capitalise on a cheap, overnight tariff, but otherwise they cost the same to heat a room to a desired temperature as those little 3kW blower heaters.

Indeed. This is the only long-term way out of the cost of expensive, finite fuel sources.  I feel for the many people who have done everything they can to keep warm and simply can't afford any more measures, but there are also a lot of people complaining about the cost of energy that have their houses warmer and more illuminated than they need to, who have things like hot tubs, waterfall showers and patio heaters, make lots of unnecessary journeys in large, inefficient vehicles and so on.  Rising fuel prices are going to make a good number of people reconsider their lifestyles.

Aircon with heat should do that space very well, £1500-2000 installed, its an air to air heat pump That really gets 3kw of heat for every 1 kw in, you could easily spend more than that installing night storage heaters and then still have higher bills.

Sadly, it will probably be pensioners who don't make a fuss and simply die from the cold.

I fear so.  It will perhaps lead to some elderly people moving in with their children, it being more efficient to heat one house of more occupants.  My elderly mother's energy costs are becoming a much larger percentage of her otherwise relatively cheap living costs, so it's a consideration for us.

All 900+ electrical heaters in this link have exactly the same efficiency:

Yet there are many firms out there who try and convince people that their product, sometimes costing £thousands is more efficient - it ain't! They should recruit a soon to be sacked politician!

How big is the room you need to heat?

Hi. It is a a newly built single floor annex with a living room, kitchen, bathroom, bedroom. Probably 6m x 30m. Relatively small

Are you sure about those dimensions? 6m x 30m is 180 sq. m. twice as big as my 3-bed semi?

Hi. Thanks for the reply. My understanding was that an oil based heater maintained the heat better than my current heater as when u turn it off the heat is completely gone. With an oil heater the heater will still remain warm. This is for a property we rent on AirBNB which has 2 1000W heaters and alone these can sometimes can be costing us £10 a day (£5 each).

£5 will buy you around 24kWh of electricity. The only way that the heaters will use that muich is if they are turned on continuously 24h of the day. If run for a more conventional 12h/day they will cost at most £2.50/day.

Is this the same property with the hot tub?

Oh man....and they're worried about efficiency of radiators?!

The hot tub is for guests of our AirBNB business. It is still very profitable but having to pay out £500 a month to run the annex is more than we expected. The hot tub allows us to charge more per night so pays for itself. We are just trying to do what we can to bring the cost of running the electric radiators down.
