Boiler broken and using immersion heater for the first time!

[amalgam786]

Hi all! Need some newbie advice please...

I have an unvented system boiler set up and the boiler has broken down due to pressure loss (engineer coming monday) I have switched off the boiler. The hot water cylinder has an immersion heater element, is it simply a case of turning the element on at the mains switch to heat the water? Does the cylinder fill it self from the cold mains automatically?

Any help would be hugely appreciated so we are able to at least have a hot shower!

regards!

The cylinder fills in the same way regardless of the energy source. Turn the immersion on to get you out of trouble.

also i'm a bit worried as I've not usedit since it was installed 10yrs ago!

Have you topped up the pressure to try and get the boiler working?

Worried how? It’ll either work or not. As per @scott_d have you tried topping the pressure up yourself?

I was just concerned about whether the immersion element would even work as its never been used - as it happens we do have warm water this morning.

wrt the boiler its a valiant ecotec plus 637 - its thrown up the error f75 but the analogue pressure gauge is in the grey (OK) zone - assuming its detected low pressure and that the pressure gauge could be faulty i've tried to add some more water, when i do this i can't hear a strong gush of water from the valve and the pressure gauge is not rising much despite adding the water. Ive then switched the boiler back on and the lcd is saying 2.9bar pressure, its trying to light but the flame icon doesn't come up on the LCD - i let it cycle 3-4 times but no flame icon, so i gave up and switched it off again.

It is probably a clogged up pressure sensor and as such you are correct to wait for your GSR engineer on Monday.
In the meantime just use the immersion.

2.9 bar pressure on that boiler won’t fire it up. F75 is usually the sensor inside the boiler or a stuck pump, both of which would need a gsr engineer. If you’re able to drain any water out to bring the pressure down, sometimes you can just reset the boiler and it’ll fire up, but this is only a temporary solution.

Hi guys

the gas engineer came and fixed it - unfortunately i was out and my lad dealt with him - so unfortunately i don't know what was done, but i just wanted to day thanks for the advice earlier!
