Lots of probs with CH and HW - please help

[New Home owner]

Just moved in to a victorian terraced house and we are experiencing lots of probs with the central heating and hot water.

The story goes....
Removed old gloworm space saver boiler from bathroom and old cylinder and had a new baxi solo 3 pfl and new cylinder installed above bathroom in bedroom 3. Rads are still the same probably about 15 years old.

Problems before.
Hot water ran out too quickly, there was only enough water to fill half a bath a day. Thermostat was knackered and it was like living in jamaca most of the time. Also kept getting airlocks in the new bath mixer tap.

Problems now with new system.
1) Central heating is off, HW is on and the rads are still hot?
2) Hot water is only filling half a bath (new cylinder is in) and hot water trying to get through but cannot - have had washing machine on but it is a cold connection not hot water.
3) Airlock in one of the upstairs rads, as bottom is hot but top is cold.

Can anyone help? Water tank in loft is quite old but looks like an adequete size.

Thanks

At a guess

1) Motorized valve faulty. Gte someone to switch the heating and hot water off on the programmer and watch and listen to the little arm on the valve head to make sure it motors across.

2)Is cylinder stat 1/3 of way from the bottom of the cylinder. Is there much head of pressure between the bottom of the cold tank and top of the cylinder. Possibly blocked.

3)You have bled it?

1) Done - moves when restarted

2) How do I check the pressure? Sorry complete novice here

3) Yes have bleed.

Thanks

Sorry the head of pressure is just the distance ie are your cold feed tank and cylinder on the same floor or is the tank in the floor above?

Is the motorized valve an old one....it may be that the ball inside the valve has swollen

Do you keep having to bleed that one rad...then ok for a while then needs bleeding again?

Valve is new - whole system is only 3 days old, and the people installing it seemed useless - this is why I am so concerned, as they had to install the cylinder twice as the first one was leaking

Cold water tank in on floor above (attic)

Have only bled once.

why don't you get them back in? You've paid a lot of money so they should leave you with a properly functioning system. If they can't make it function properly shouldn't they pay the cost of someone else coming in to fix the problems for you?
