Do we have a difinitive answer?

For a given area and assuming the same Economy 7 or Economy 10 supply, for a 3 bed house, is it cheaper to run NSH or EWCH?

Penny for penny it is always more expensive to run electric heating. (At the moment - things may change as gas prices increase)

Storage heating has the added disadvantage of you needing to anticipate tomorrow's weather as well.
 
Depends on your heating requirements, if you are out all day E7 is getting a bit cool by evening, but also the maintenance cost of E7 is a lot less the gas/oil, no need for regular servicing etc
 
ive got electric wet heating , im on scottish power 2000 economy rate .
cheap rate 02.00-08.00,10.00-16.30,18.30-2400.

thanks all.

Runci21, have you had it long? what are your running costs please? Total electric costs? Do you use a thermostore heated by economy and use that for the EWCH or direct from electric boiler to CH?
 
only had meter fitted for two weeks and with this weather ive not had heating on .
my hot water comes from the immersion but im going to change that so boiler runs through immersion tank before heading to radiators .
ive got a trianco aztec 12 kw system which heats my 3 bedroom semi ( 200 year old cottage,s)
 
water comes direct from boiler when its called for , sytem is controlled by danfoss tp5000 +rf fully adjustable times and temperture in each time zone . with the rate i have it's off peak 18 hours off the day .
i needed to change consumer unit to handle two incoming meter tails , i also feed immersion and a dedicated ring main for utility room on cheap rate .

I wouldn't do that - convert it to S or Y plan.

I would go for wet ELECTRIC. Atleast with this you could actually convert to gas/oil in the future.

With storage rads, you generally fit them to the principle rooms, and are better to use a couple combination heaters as well. The rest of the rooms are best with panel heaters.
 
where i live there is no mains gas available and i did not have a site for an oil tank .
there are a lot off people in the nearby village that have converted from bulk gas to electric wet heating .
my dad's electric bill is about £ 45 a month for his total electricity consumption

Blimey... I don't pay that much for a quarter!

But then I don't have central heating because it's never cold enough in this country. ;)
 
what type off heating do you have at the moment ??
do you have radiators in place ??

This is a new home I am moving to in a village with no gas supply. At the moment it is heated by night storage heaters so has no radiators, just the NSH.

I am used to gas CH and consider that more convenient than NSH - not having to know what tomorrow's weather is etc. So, I am thinking about having EWCH installed instead and wanted to know the differnece in the two's electricity costs.

I want to move the existing hot water cylinder anyway as it is in the 'wrong' place for us, so might as well think ahead and have the thermostore put in instead. Whether we get the whole EWCH done at the same time is not decided, but probably best to save on the upheaval again later (bad enough with the moving in).

I am thinking of the thermostore, electric boiler, maybe 2 large rads and 5-6 small rads.

I seem to prefer electric showers as they only use power whilst being used, so the thermostore will really only be heating the CH with occasional washing up, maybe bath (but could put up with extra boost to thermostore for that) - we tend to shower more than bath, but it is nice occasionally.

Dishwasher is cold supplied, as is washing machine.

maybe but that will only happen if we get a government with the guts to build some nuke plants. Otherwise with almost all of our new power stations being gas i would expect electricity prices to more or less track gas prices.

if you are going to go for electric heating go for heat pumps of some form, prefferablly ground source ones. The heat forced in from outside by a heat pump should more than make up for the losses in the power generation.
 
Wow Plugwash!! :D

Heat Pumps sound great. Just when I thought I knew what I was doing. :rolleyes:

Had a quick read through the Heat Pump Network homepage - must find some time to study better. From what I just read, it seems that this technology is CH when cold and AC when warm (by reversing the flow). That can't be bad.

I have a large patio area at the rear of the new home that is S/SW facing. I could remove that, place the collectors under it and relay. Great sun soak I would think. Hmmm... I suppose also nice under-patio heating if I switch to AC in summer - might cause a meltdown of my flip-flops ;)

Anyway it gives much food for thought. Anyone actually installed this and can give info/recommendations?
 
heat pumps are great!

For cooling, you need indoor fanned units, not underfloor. UF aircon just gives cold feet and frostbite :LOL:

I would go for fanned units anyway, they are very quiet and unobtrusive.

They can be up to 400% efficient! :D
