Powerbank for an electric oil heater using Economy 7

Ecoflow will output near to 2kW, as proved by someone testing it to charge a EV.

But it is the cost to return that will be the biggest issue.

Anyone know about these things? Thanks

No, but ... a bit of 'O' level physics might help. 

It looks as if common oil-filled radiators are in the range 0.5 - 2.5 kW. To have one of these operating from, say, 5 -11 PM would use 3 - 15 kWh. 3 kWh is probably manageable, but 15 kWh is a lot more than a single camping powerpack could hold. They're typically 0.3 - 2.0 kWh. 

You're looking for a way to store cheap energy to use a few hours later. That's just what storage heaters are designed to do, so rather than investing a not inconsiderable sum in a battery, you might consider upgrading and/or expanding your storage heater park. Modern high-heat-retention models are much less prone to running out of steam in the afternoon than their older cousins are.

Thank you all for the input, as I said, it was an idle thought as I'd come across the power stations with people in RV's/camper vans and a little spark went off in my head!  Yes, definitely the right answer would be to upgrade our storage heaters, we have 4 older Dimplex XLSN NSHs and a new Quantum.  Just need to budget to replace one a year I think starting with the lounge as we typically don't use that in the day time, only evenings.  Thanks again

1kWh isnt going to be much use for heating - realistically.

The delta 2 variant is £1599 for the 2kWh version - an additional 2kW battery module - another £999.  Which might cover a reasonable top up demand - but it's 2 pretty large kit boxes - to have sitting around a typical living room - to plug a heater into. 

But then definitely into same costs as replacing 1 or 2 storage heaters - or fitting supplemental ones.  

Albeit with options to power other devices.

But even if used all 4kWh for daily use - £2600 / (4 kWh/d*365d/yr * say 0.15£/kWh rate saving) = nearly 12 years pay back if got that right.

Of course a lot cheaper than buying an EV and using that as store - as some do.
