Help! What heaters do we go for? Dimplex Quantam?

try Elnur and Creda

Creda heating is a Glen Dimplex group company

Does it really matter who produces them? They are an alternative to Quantums. They aren't identical to Quantum, nor are they quite as expensive.

danrv said "Just thought there was some cheap copies of the Quantum knocking about" & I was pointing out t's not just a cheap copy from some no-name company. There is quite possibly a fair amount of shared technology/design thinking & I say that as someone who used to work on the sales side for a part of Glen Dimplex where 1 or 2 of our main competitors were actually sister companies.

My storage heaters are wearing out too, and I wonder if economy 7 is going to stay around long enough to justify spending the money on newer ones or if I should gamble on a mini split working out...

I realize it’s an older post and not sure how it worked out for the OP.
That’s my slight reservation with installing three Quantums for main heating. Cheap night time electricity in the future.
I’m still in between these and small multi split aircon. Will electricity prices rise to a point where storage heating is no longer viable?

Probably a can of worms whatever you do. 

Overnight usage of electricity will soar because EVs are supposed to be supposed to be taking over, so there won't be so much need to promote E7.  That's already happening, E7 cheap rates are seldom if ever close to half the price of single rate; often a cheap single rate from a small company will be cheaper than the E7 cheap rate from one of the big boys.

More than likely that gas and other fossil fuels will be taxed to subsidise electricity, so fewer escape options there.  Green hydrogen from electrolysis may eventually play a part but (unless subsidised) is unlikely to be cheaper than using that electricity directly, and the extra demand for the electricity it needs is likely to raise electricity prices in general.

IIRC aircon does not qualify for the Renewable Heat Incentive, so although its running costs may be lower than for NSHs its capital costs are likely to be higher.

Thanks.
I think I’m going to have to open a can of worms as I’m possibly the only person in the country running electric warm air heating 😕
I’d prefer to take higher capltal cost (no grant) over NSH’s. Depending on the system, it would probably work out roughly the same as ASHP and radiators with RHI (while still available).
Quantum NSH - hopefully very little maintenance and ok is off peak prices stay low. Cheaper capital cost.
Air-con (ductless) Expensive capital cost but cheaper than ducted. Running costs cheaper than NSH’s and certainly electric warm air. 
Developing technology and requires servicing. Heating & cooling ability.

I had that in my last house, one big central NSH with a fan and ducts to the rooms. It worked well while it lasted but once the fan bearings went it was impossible to get it fixed for a sensible price (the only heating co I could get to come out made a right bodge job and charged handsomely for doing so).

I did phone a couple of A/C places to see if they could replace the NSH with a US-style central AAHP but they weren't interested.

In the end I replaced it with a wet gas CH system.

That was a decade or so ago. If I was in the same position today I'd definitely look at a ductless multi split system, even with the planning permission hurdle.

Thanks for the reply.
Good to hear from someone with experience of electric warm air.
It’s a complicated system to upgrade from with no mains gas, no E7 circuit or radiators.
Also ducting that can’t be used.

It’s had a new fan and could possibly renew that if needed. It’s more that it’s on an old, very expensive Economy 10 tariff with no option to swap. 
It could run on E7 but I just want something more up to date.
An aircon company has had a look and can fit US style ducted Aircon throughout. £13k though and no grant.
So, looking at ductless multi split as you suggest. Either just for main living spaces or whole property.
Had one quote for around £7k for an outside unit and five or six indoor air handlers.

I’m going for a Toshiba multi split for main living area heating/cooling. Bedrooms will be electric rads for now but the installer said that upper level aircon could be added later.
I mentioned planning permission during the survey but said it won’t be needed.
There is a considerable distance of 18-20m to the next property.
