💡 Tip from SejlStrøm

If you install this in a boat or camper, it really makes sense to combine it with:

• lithium battery (low power consumption = longer operating time)
• solar panels (so you can be completely off-grid)

This is where it really stands out – you get both heat and hot water without being dependent on anything else.
