The NSH supplier had also confirmed the only differnence with the new model is more functionality and not efficency !  So I will keep the night storage heater, can you set it to come on at a certain time? as this NSH is not new.

Modern fan assisted high heat retention NSHs can be slightly cheaper to run because they don't lose so much heat overnight, but probably not worth replacing existing ones because the payback time could be lengthy.  They may also have clever controls e.g. so that they don't take a full charge if the weather warms up and you can tell them the times when you want them to warm the room.

NSHs should be wired to a circuit controlled by the meter that's only livened up at the cheap rate times.  Newer ones usually have both an E7 supply for charging and a 24h supply for the controller and the fan.  However, some can be run from just a 24h supply, but you need to take great care to make sure that they are correctly slaved to the meter's E7 times otherwise you'll be hit with a massive bill if they're using any day rate electricity.

Similar thinking applies to the immersion heater, best on an E7 circuit, but can be used at your peril with a 24 circuit and a local timer.  Always make sure that any Boost switch for a second immersion heater (halfway up the tank) is left switched off.

Appreciate the links, I had only one quote as there was no other certified person who knows how to repair the NSH in my area. Does it have to be a certified person, what are the risks for getting a non certified electrician to repair?

Also, I was told that with the double glazed windows closed (and / if there is not enough ventilation),  the condensation will be created from the bricks in NSH, due to how the old NSH were built? So maybe to replace the NSH?

I have some NSH older than 30 years, still fully working and no condensation problems. Sounds like you encountered a rogue electrician. Any electrician will be able to repair your NSH.

can you tell me, if the dial on the NSH has come loose, is there another way to tell whether it is working or not?

I'm not sure but the dial should just control the thermostat. There may be some way of popping the cover and manually adjusting this internally if the dial is no longer controlling the thermostat. You'd be better getting someone who knows about these type of things to take a look and see if they can figure it out.   The input dial on my ancient Dunlop-Westayr NSG just moves an arm on a spring to control the thermostat.

Is this just the knob having come loose  - then it can be tightened using a very small screwdriver to tighten the grubscrew.

@MQA  That's a simple DIY job - either a grub screw or needs an allen key
