Putting Mega flow in a hole in the floor
Seems the time for property/boiler related questions so here's mine.
We would like to put a megaflo-type system in our house. The best place is cupboard under the stairs. However the 'ceiling' of the highest
bit is about 1800mm and the 300lt vertical megaflos are taller than this. A horizontal one won't fit.
So, could I dig a ~500mm pit in the floor give it a 'proper' floor of its own with its own brick walls and sit the mega flow in the pit?
The pit would be against an external wall.
The current floor of the house (built 1964) is soil with a layer of small rubble, a load of large rubble and then a concrete slab.
Other alternative is the loft but supporting ~350kg will need a lot of reinforcing and inconvenience the planned loft conversion!
Thanks,
James
I'm also investigating other manufacturers to see if they do a short, fat tank but have been recommended to stick with megaflo.

Not sure if you have a DPC in the floor, ours is a 50's house and doesn't. But that would be my concern, tanking it out. Should be OK with
vandex or similar.
Not sure how building regs would view it, or if I would even ask.
But have a think about footings. To go 500mm down, you need to go at least 600mm to get just a 4" of concrete in there. And you will probably be
below the existing footings. Easy enough to sort though.

You'll break through any damp course as I assume its a concrete base so you'll have to tank it or ground water could rise

Not wanting to redesign your house, but 300litre one sounds very big.
Ours is 145litres and we (2 kids, 1 wife, large bath) don't run out of hot water.

300L is pretty big, you might well get away with a smaller one unless you have several bathrooms and loads of occupants
Megaflow are good, but there are loads of equally good alternatives.
Fit a twin coil solar cylinder they don't cost much more, you can always retro fit the panels/solar kit at a later date to spread cost.
Nothing wrong with the pit idea as long as you can make it watertight and leave enough room round the cylinder for pipework
installation and future maintenance.

MacDonald engineering will custom build a cylinder to your dims.
Megaflow are good but also expensive.
A 200 litre cylinder should be enough I would have thought, as a rule of thumb I use 50 litres a bedroom.

Which other manufacturers would you recommend as being as good as Megaflo but cheaper? I spotted a Worcester one (greenstore) but no idea how good it
is compared to a JAB DUC or anyone else!
One thing I like about the Megaflo is they do the 'system fit' model which is pre-built with all the extras. Do other manufacturers do
this with theirs? Any examples?
It's to probably go with a Worcester Bosch Greenstar 24i (as recommended by the Gas Safe plumber I talked to awhile ago.
Thanks!
