I meant to add ..... if I apply pressure to the radiator against the wall, the noise stops. Perhaps the rad hasn't been fitted properly?

Hi all I had a full new central heating system installed. All radiators fine except the one in my bedroom is driving me nuts. When the boiler is turned on the rad makes a loud tickling sound every 5 seconds for the first 10mins whilst the rad is filling up. Installers have been out...

Hi. I've just bought a house with storage heating and I am looking into upgrading to an electric boiler. I've been advised that the Thermaflow is the best, and is cheap(ish) to run. Its a 9KW unit and will run on an Economy 2000 tarrif with 18 hours off peak, charged at £0.07pence per kw...

I havent properly moved in yet, so hopefully be back up in the next day or so and can take a picture. Thanks for your time and help.

Strange then. Shall I just leave them switched on and it wont make a difference? Oh dear hopefully this time next year I will be an expert on this!

Yes thats correct. 2 large red switches that are both switched on.

They are linked to the cylinder

There are 2 cables and 2 switches in the cupboard where the tank is.

Forgive me as I this is all new to me. Unfortunately I have no idea how many units are running, if its just 1 or 2? How do you tell?

Not at the mains fuse box, just at the Hortsmann box. I think the previous owners must have had the timer set to during the day, as the clock timer was way off?

We had the hot water switch (timer) turned off for several days - does this affect the clock?

Phew! Hopefully that sorts it out. I also read on the instructions that the battery will run on stand by for up to 6 days and we havent used the water in over 6 days, so this is probably why we had to re-set the clock. Thanks again as its very expensive to run during the day. Karen

Right now the dial (outer circle) is set at 2pm but I'm assuming this should be set to the current time, ie 8pm? Will that mean that if I set the dial to the correct time and switch the timer on, it will only heat the water on off peak? Thanks.

I'm not in the house just now, but my partner is away to check what the dial is at right now. I shall let you know. I appreciate your help.

Hi, I have no idea. Its set on Winter dial? I only want to heat the water during the night off peak.

Hi I have just moved into a new house with storage heating (I know how to work this) and immersion heating system, which is controlled by a Hortsmann Economy 7 box. I assume that my hot water is heated during the night at the off peak tarrif, however, I am not sure? There is a switch on the...
