Now to get system same or similar to thills on this thread. Only concern is how long to keep heaters on when we come home and how long does it last, hopefully for the whole evening.

That will depend on the size and insulation properties of your property.

For xx kWh you will produce the same amount of heat as 'thills'.

Thanks again, home is std 3 bed semi, loft insulation, d/g windows no cavity wall. So if I put heaters in then basicaly it's a trial and error run till I get it right then.

Find the draughts, insulate as much as you can, keep the heat you paid for, in your property!

Hi All,

I thought I'd post an update on electric heating, after two attempts to get planning for a heat pump, I gave up.
I have no gas!

Storage heaters aren't much good for me, I'm out all day, so it had to be direct/instant electric - the worst for cost possible!!!!!

I kept the E7 tariff, Scottish power off an E7 with 3.7p night & 8.1p day, so no point in dumping the E7.
The flat is 78M2, D/Glazed, cavity brick etc.

I installed 5 x 2KW clauden wireless heater, a big overkill really, and use 2 clauden TX controlers.
The E7 rate covers the 200 litre hot water and early morning warm up.
The system is in two zones, bedroom & living, so with a bit of thought, you can heat only the needed zone.
The 10KW warms the place up from 5 to warm in about 10 minutes, about as quick as making a cup of tea! so you can pretty much heat on demand only, when home.

The 5 heaters and 2 controllers cost £650.00, from Dealec, it's all plug in so no other costs involved.

THERE IS NO WAY THIS BEATS GAS COSTS

But, if your lifestyle suits, the initial cost is dirt cheap, the maintenance costs are zero, and the efficiency is 100%.
Just don't get conned into panel heaters, costing £100s each, that do nothing more than a £20 convector!!!

I can't have GCH, or I would, but I'm not unhappy that I don't have a heat pump!
I think one addition, might be a big fan assisted storage heater, for mainly weekend use, oddly, no manufacture will give any data on the heat loss when the fan isn't on?
What you need, is a really good heat store, topped up at night rate, that does not leak heat.

Anyone tried anything?

Funny you should mention a heat store. I have a 210Litre thermal store with 2x 3Kw immersion heaters. i strongly recommend them - mains pressure hot water at last! I am considering connecting up the radiator circuit with a pump and expansion vessel so the thermal store will heat the house as well but after calculating the load the eating will require I'd need to upgrade the immersion heaters to 2x 6Kw - Quite pricy!

Thanks, at the moment only cheap rate benefit is between 0500-0730, both at work all day come home and just lukewarm rooms. Have checked comparison sites and would be cheaper off E7 go to std rate,saving in peak time usage outweighs cheap rate of E7.

thills how do you get around this. My E7 comes on 2230-2359 then 0200-0730 so rooms need extra heating during evening.

Thanks

This is my experience. Southern Elec E10 tariff = Peak 12.10p Off peak = 8.64p
2008/09 Heating (storage heaters) 13382KWH = £1183
2008/09 All other electric 15271 = £1847
Total for year £3030

Change to OVO fixed tariff for everything 8.61p

2009/10 23232 KWH total for year £2000.28p

Saving £1030

Assume normal electric same each year at 15271 then:

Storage heating used 13,382 units (Four heaters)
Oil filled heaters used 7961 units (Five oil and two convection)

I see where you're coming from, this way you can have heat on at times to suit yourself not timed as with E7. So warmer rooms in evenings when you come home, Can you tell me what OVO is and does it apply to other suppliers.
Thanks

OVO is an alternative supplier. I switched from Southern electric last year as their rates were much cheaper. I am on a fixed rate of 8.61 inc vat until 22 Dec. I have opted to continue with a fixed rate of 9.19p inc vat for a further year. They have variable tariffs also and dual fuel. All is done on line but they also have a phone help desk. EDF would have been slightly cheaper but their tariff was only fixed until March 2011 so I am staying. It would cost me £30 to get out of the fixed tariff so if their price drops I will just pay the £30 and change to their cheaper tariff. They have a website search OVO.

Cheers,will check out their website.You say EDF were slightly cheaper can you tell me which tariff it was so that I can compare the two and was the EDF one a flat rate pence per unit like OVO.

When using electric heaters the thermostat and timers are key.

For example the five oil filled radiators (Delonghi Rapido 3KW with 7 heat settings) are used on the 2.5KW setting and thermostat level 3.

If they were on 24/7 the total cost over a year would be:

5 x 2.5 x24 x 365 x 0.0861 = £9428

Of course not used in summer, mainly on from 4pm to 12pm in lounge and 6am - 8am and 9pm - 12pm in bed rooms = £685 over a year

EDF was online saver 7 at about 8.7p (approx - make sure the cost includes vat = 5%)

If you look carefully on the OVO site you can find the tariff table which gives all tariffs across the regions.
