The Gledhill and ACV Heatmaster floor mounted combis have full electric backup for CH and DHW.
ACV Heatmaster has electric backup? Not on any we've seen........
I stand corrected. The ACV tank-in-tank cylinder when running CH off the cylinder have electric backup. I believe the highest rating immersion is 12 kw that can fit in a standard immersion boss, so reasonable backup. Anyone know of any higher immersions available?
The Heat Master is just a tank-in-tank with a burner running through it. Well nearly. An electric boiler with a pump can heat the Heatmaster. Tap into the pipes at the top and bottom of the outer cylinder
