can you help me with my old boiler

[tomestone]

I have a flat which has an old boiler for the central heating system. It works well in terms of heating the flat and heating the water, and I had it serviced last summer. But my problem is the water. The boiler is a Glowarm fuelsaver mark II and I have a water pump - it is green and it has the name of WILO and then underneath GOLD 50 and a number of 052008763. The stored hot water pumped through the system is extraordinarily slow. It takes me 25-30 minutes to run a reasonable bath. 20 minutes to fill a sink for washing dishes. I wonder what I can do to make this any better, your help would be really appreciated, thanks in anticipation. X.

is it a combination boiler

[tomestone]

It appears to just have a water heater .And the pump in the bathroom is for the radiators via the emirsion tank.
The water pressure in the radiator system is normal,but the pressure from the boiler to the hot taps system is very weak and slow.

If its not a combi boiler, have you checked the ball valve in your cold water tank in the loft. Often they can become encrusted with lime scale - I've even seen one stuck in the fully closed position hanging in free air!

I'll try this. But is there anything else it could be. I am thinking aof replacing the boiler but don't know if I should if it is not going to be any better. Many thanks.

We had a boiler in a previous rented property that had instant water heat, and no hot water storage tank.

Filling a bath was a slow process, but not that slow.

When an engineer came to service it we complained how slow it was, and with a little tweak on a valve on one of the pipes it speeded up dramatically. It slowed again later, but by moving this valve a bit I could speed it up again. I suspect limescale.

if its a traditional tank and cylinder system you have then the stored hot water is not pumped to your hot tap it just drops from the hot water storeage cylinder to your tap via gravity.
its hard without being able to investigate in person but i suspect you could have an airlock which is something my own system is prone to. basically my missus keeps running the bath until the hot water completely runs out and the system then airlocks because our header tank does not re-fill the cylinder quick enough as the hot water leaves it.
to solve this i run a hose pipe from the cold tap to the hot, turn both taps on and blast cold water up the hot pipe to clear the air-lock.
