Installation alternative
ACCUMULATOR TANK (SP 300)
For installing ELK 213 to SP 300 accessory "Thread
flange kit" is required (Part no. 022 077).
In the event of large hot water demands, ELK 213, in-
stalled on double-jacket accumulator tank type, can be
used to heat the domestic hot water. This is also a good
solution for aggressive or hard water.
Recommended thermostat setting: 75 °C

BOILER WITH INTERNAL WATER HEATER
With the immersion heater installed on an existing boiler,
the existing control equipment is used.
Install the electric heater so that external heating does
not cause overheating, for example, in front of the fire-
box door (to prevent flames blowing out) or next to the
flue pipe (to prevent damaging heat radiation). A suitable
location is normally at the side of the boiler, directly on
the double jacketed heater’s flanges or similar location.
When the electric heater is installed on the existing
wood boiler and is solely responsible for the heating
demand, the flue should be sealed.
