Can I have the central heating on even though the grundfos water booster has packed in?

[bomitie]

As per title I have a water booster and it is now broken but I am not sure I can have heating on as it may be topped up by the booster. The booster was for taps and 2 power showers so no no showers and only a trickle from cold less from the hot. Its an oil fired CH system with a condensing boiler. A bit concerned I may do damage. I believe the CH is a closed system. 13 years old and has worked flawlessly.

You may have a vented system with a small header tank (Feed&Expansion) in the attic which will provide a reserve and will/should last for weeks/months without any makeup required from the ballcock OR you may have a unvented system, in which case you will see a red expansion vessel which should have a top up valve with a pressure gauge somewhere close to it, it should read ~0.75/1.0 bar when cold & ~ 1.5/2.0 bar when hot, this should also last for weeks on end without the need for a top up.

Does your boiler have a pressure gauge on the front panel? Or a means of filling system alternatively in an airing cupboard? The water booster wont affect the heating system be it closed or open vented

Thanks both, its got that red expansion vessel in the boiler house. So heating is on.
