Hi, I've just recently moved home and lookingfor some general advice please from any experts out there. We have a HeatraeSadia CL210 Megaflo unvented hot water cylinder in the airing cupboard. The pressure forthe taps and showers is absolutely great but we've just started having centralheating and boiler issues. The guys have been out from the heating companywe've got central heating cover with and they seem to be confused with thesetup that we have. I assumed as we have an unvented hot water cylinder thatthe boiler would be a system boiler and pressurised in terms of the heatingsystem. Turns out we've got a glow worm 18hxi regular boiler which I found outfrom glow worm and we've got some sort of header or cold water tank in the loftwith a pump in the airing cupboard. I know pretty much nothing about plumbingor heating systems, but can anyone advise me whether having a regular boiler and pump is normal and quite standard alongside anunvented hot water cylinder? I would assume the setup should normally be an unventedsystem or vented for both heating and hot water or am I in the little bit ofknowledge is dangerous / you know nothing about heating go away son category?
