1000 Litre Thermal Store that will go through 700mm front door?

[Mark Townshend]

Have a renovation project on the go, and want to use a 1000 litre thermal store, 18kw log boiler, some Solar thermal and Underfloor heating and Radiators.
I have a convenient hallway room between the 2 parts of the house, which would make a nice "Plant Room", for all the heating stuff, but the front door is 700mm wide.

Anyone know of a tall thin Thermal store, 1000 litres or so, with 70-100mm insulation?
That would fit though the door?

thanks.

500mm wide cylinder (no insulation) with 1000l capacity would be over 5m tall?

790x2130 for a 1000litres. If it's a reno can't you just whip out the door frame and edge of a wall whilst you get the tank in there. Note the height too!

2 x 500s plumbed symetrically?

Inflatable cylinder!
Now there's an idea

Great Big feck off hot water bottle

Ideally, yes, but adjoining the door frame is the fibreglass DNO service cabinet.

We today have had a narrow pair of french doors put in at the back of this room which open to about 1m, but there are 3 steps down to an uneven back garden.
May have to rig something up.
Do these cylinders have any kind of lifting attachments?, I guess they are going to be 200kg +

2220 Ceiling height in that room so looks like 790 is going to be it, or a smaller volume

That is an idea, maybe separate DHW and heating, so only need to heat one tank in Summer.
Guess that nearly doubles the cost though.

The tanks aren't that heavy- even at that size I'd be surprised if it was over 100kg. Scaff planks up the steps, shuttering ply across the garden and a couple of dollies ratchet-strapped to the cylinder should do it- stand it up when you get it in (but check there's room to do that, if it is 790 dia 2100 tall you'd need 2250 headroom)

Has this all been properly specified or are you trying to make it up as you go along? I presume the 18kW wood log boiler you're proposing is an automatic one and not just a woodburning stove with a back boiler?

At 18kW it'll take about 3½ hours to get a 1000 litre store up to temperature, and burn around 16kg of wood getting there. It'll need 4.5kg of wood an hour to maintain temperature if you're drawing the full 18kw out of it (regardless of store size). Heating for 12 hours a day is over 50kg of wood a day. What will you do if you go away for a week in Winter? Will you have a hopper large enough to hold 350kg of wood? Who will load it?

Just think about the practicalities. A few years ago I worked on a job where a customer went for a manually loaded log boiler, which he thought was brilliant until he went through his first Winter, after which he absolutely hated it because he was forever humping logs around

Got to echo @muggles warning on how labour intensive fuelling a big woodburner is- mine is only 11kw (7kw into the water) & on timber you're chucking logs at it every 15 minutes to heat half the house. Typical burn for a winter's day is 5 of those supermarket bail totes full of wood...tedious. But the real flame is lovely
