Is the price list for "used" or new? If new that not that expensive.

I just bought an Alpha Smart i18 instant heater. Cost alone oledi 600+

But I supposed for storage heater, you have to factor in the copper piping, that will really jack up the final cost.

Hopefully by next year can save enough budget......

My new house has a heater point on the concrete roof slab, right next to the water tank.
(Don't know what developer was thinking)

Can this type of storage heater be mounted on top? In open air.
