Can I turn off electric water heater?

by s4room » Thu Aug 13, 2009 12:00 am

Hi,

I just moved into a flat. At old address, gas boiler was used. Now, everything in the flat uses electricity. I'm new to electric water heater and do not really understand how it works. I find out that the electric water heater is powered on 24/7. Can I turn off the heater when I do not use it, and switch it on when I'm about to use it, e.g. shower?

There are two wall mounted convector panel heaters in the flat. Thus, I think the water heater only provides hot supply for shower and taps.

The model of water heater in my flat is "OSO 20 RD125 (DIRECT model)".
Google "osohotwater.com/uk/produc...l_details.html"

The specifications of the water heater is:

There are several AC main power switches around the heater:

There is one switch labelled as "Isolator". I'm not sure if it is for the heater. If it's, please advise its function in the heating system.

Close-up view of switches. There are four red leds on the TIMER panel, and all of them are ON. What does it mean?

The hot water output pipe is insulated.

[Questions]
[1] Should I turn it off if I use the water heater model as described above?
[2] Should I turn both (4) and (5) switches off, or only either of them?
[3] What is the function of the ISOLATOR?
[4] Any idea how does the timer work?
[5] Is it safe to switch it off during winter? Will this cause damage to the water pipe?

Thanks

don't seem to be able to look at your pics - can you use an alternative website to post them on?
