Discuss Immersion Heater - PV electricity in the Central Heating Systems area at ElectriciansForums.net
Incidentally, has anyone had anything to do with the Engensia Solar 24 box, which appears to do the same as Immersun, but cheaper still - and appears to have been developed on this forum?

Hi all. These recircculating pumping systems seem all very neat but by the time you've bought a decent pump, two thermostats etc the overall cost sneaks up appreciably. Just wondering if anyone has had any experience retrofitting a second immersion heater at the bottom of the tank? On reflection, shame but at a glance the central heating coils of a standard tank seem to sit too close to the bottom to fit a standard immersion anyway.

The longest top fitting immersion that fits is not inexpensive. Or if you live in a hard water area bite the bullet and change your tank for a taller or dual element one. It’s going to fail someday anyway due to the hard water.
I think they work best when they start with cold water, which washes certain foods off before they "bake" on.I have also wondered about how to best use the hot water this generates, and was thinking about putting a thermostatic mixer valve in to the feed for the dishwasher and washing machine (both cold feed only), to give them warm water at about 30-40C.
