In a “liquid to liquid” system: Is there any emergency heat (electric coil or element) available? How many Kilowatts?
The emergency electric heat on a Liquid to Liquid System would normally be installed externally. However, if you need it installed internally we could probably do that prior to shipping. It would simply be a submersible heating element. I believe the size to go to 20 Kw very easily. Our electronics have a 2 stage board for heating (W1 heat stage 1 & W2 heat stage 2) already so the control is very simply. Wiring and fusing would normally be done separately. One main feed for the unit and one main feed for the back-up element. This is more of an electrical guideline and it may be different in Europe. This we can discuss as it becomes an issue.
