Please ensure that all steps of the installation schedule are carried out in this order, and only this order. Failing
to carry out the installation in this order may result in damage to the boiler and incorrect function of the system.
INSTALLATION SCHEDULE
Electric Boilers
1. HEAT LOSS CALCULATION.
Correctly calculate the correct size unit for the properties heating demand. We regret to inform you that after
installation there is no way to boost the output of the unit so it is important you get the correct unit for the
property. Strom are unable to assist with these calculations.
2. HOT WATER CALCULATION.
For combination units ensure that the boiler has a sufficient heat output to provide the correct temperature &
flow of water required for the application. If you need help calculating this please contact Strom.
3. VOLTAGE & LOAD CALCULATION.
Typically the UK single phase supply is 230V, all our technical data is based on this, however you should do a
measurement and correctly dtermine the correct input voltage, this will determine the size of breaker required.
All our breaker recommendations are only that, and should be checked against your requirements.
4. MAINS WATER PRESSURE.
The maximum rated pressure of the units is 6bar, where water pressure is approaching this limit, or where
dynamic pressure varies and may exceed this a pressure reducing set on the mains supply should be installed.

PRIOR TO INSTALLATION
All of these considerations must be made prior to at least installation but preferably before purchase is made.
Regretably once the box to the boiler has been opened we are unable to accept returns of the product unless the
product is faulty or does not operate as advertised by Strom.
IMPORTANT
It is important that once you start installing the boiler you do not leave it unattended with power connected or
water in the circuits unless the whole installation and all steps have been completed. If you intend to leave the
boiler unattended without completing the installation you should ensure that no leaks are present or possible,
and that the electric have been isolated.
