No, still one in one out.
They may be better insulated and make use of the stored heat better allowing for more controllable heat output.
At a stretch you could argue they are less likely to need a second source 'boost' late in the day?
So the heat outlet is now at the bottom so heat cant naturally escape out the old flap that used to be at the top, they rely on a fan to blow air up through the bricks and back down an outlet at the bottom so they should be more efficient that they hold onto the heat until this fan is timed to come on. It also allegedly learns exactly how much heat to put into the bricks.
BUT, they have the ability to use 1 element to boost the core temperature if it is dropping late in the day, or if its stone cold itl just blow warm air out, but obviously this element can run on peak rate, so will cost more, also the extra installation costs needing second supply to them, aaaannd the increase in initial price over a old one, theeennnn, electronics ie screen, fan, pcb, to go wrong, I dont know how cost effective they are.
NEW POST on OLD THEME
Went to look at a job the other day 'upgrading 'Basic' storage heaters'!
The client said that when they moved in the flat was nice and cosy but had BIG electricity bills!
So they turned the heaters down (and off in one room rarely used) and found that the bills were a lot less, but COLD!
They had been given some advice to upgrade to Dimplex Quantum.
I tried to explain that unfortunately they cant have it both ways 'cheap' bills and cosy house!
I have never fitted Quantum but said that I would also need to install a 24hour supply to each heater which the client clearly didn't comprehend.
But the crux of the matter was that I could not 'guarantee' that the bills would be less despite the advisor saying the Quantum are more efficient!
I couldn't see that there would being sufficient benefit in upgrading from old but working basic storage heaters to quantum in terms of output v bills let alone any return on the capital cost.
I walked away in the end ……………… Would you have done the same or see things differently?
The maths don't stack up at all... I worked it all out a while ago. Just looking at the materials cost, using the cheapest available and 2nd hand where practical, the payback period is >20years. This period is beyond the useful life of most of the equipment !As technology improves for battery storage, it may well be most cost effective to use battery storage.
Recharge overnight at cheep rate, use battery for daytime use and shortly before night rate comes on again, push any spare charge you have left Back into the grid tor a rebate.
I don’t think the maths work out just yet but soon as battery costs continue to reduce it may well be a winner.
Some manufacturers are already selling devices that do this but at the moment they are too expensive for the masses.
Peak/off Peak rate tariff schemes don't really work UNLESS the homeowner dedicates their life to switching usage into the Off Peak period. This is not easy and often very expensive to do... as a minimum, washing machines and dishwashers may need to be changed to ones with a delayed start function. Larger hot water tanks may be needed to ensure that it's all heated at night.... it really is something you have to dedicate your life to. And after all this... you might save a few £'s every year.The general feeling I'm getting is that there is no great advantage 'upgrading' to quantum (or similar) and with Little Sparks reference to Rointe may be that due to being on 'peak rate' may work out more expensive in the long run.
Every manufacturer advises their products as being “the one”
Rointe for example have stacks of literature, laboratory results etc showing their heaters being most efficient against Quantum for one.
They only need a 24hr supply, removing the off peak completely (which also removes the inflated day rate!)
However, these are also expensive to buy
Dimplex welcomes ruling on misleading advertising for heaters
Dimplex has welcomed a ruling from the Advertising Standards Authority (ASA) which has banned an electric heating manufacturer from using unsubstantiated and misleading claims related to energy efficiency end emissions. The full ASA ruling ca...www.buildingcentre.co.uk
Rointe were misrepresenting the truth
