Maaasive expansion tank

[ViPar]

Hi All
I have just moved into a new house in deepest west Wales. It is a recently converted old farm house. It is a modest sized house with about a dozen radiators. The plumbing is relatively quite new (about 10 years). In the corner of our utility room the is an absolutely huge pressure vessel attached to pipes coming out of the boiler. It is 450 litres. (Challenger Series 450 Litre Vertical Pressure Vessel).
Can anyone explain why it is so massive???

Cheers
Vincent

It's an accumulator for your water, I presume you have poor water flow rate and or pressure, and the water to your taps is pumped.

Hi sxturbo, your link is correct, it is exactly that one. My flow rate out the taps is not great, I am not aware of a pump? But we are on a long blue pipe running up the valley so yes, low pressure/flow rate. So its a sort of reservoir/buffer.

the poor flow rate from the taps could be 2 things, the hoses on modern taps restrict the flow rate significantly, the accumulator may need re-pressurising.

is the boiler a combi?

Not a combi, we have a pressurised hot water tank, which holds its pressure well. But the water pressure on the radiator circuit (dial in the boiler) keeps drifting down to zero. Can't find any leaky radiators.

The pump will be at the other end of the long blue pipe.
