if you have a combi boiler your hot water pressure should be more or less the same as the cold. if it's a system boiler (you will have a hot water cylinder) then the hot water pressure is governed by the height of the cylinders' header tank
as you are in a ground flat then i suspect that this is why you have poor hot water pressure as the header tank will be just above the cylinder on the ground floor
there are options open to you but it will cost you your hard earned ���'s
Yep... I'd agree - that first picture is of an immersion tank (ie a hot water boiler) - but it is flipping huge ! The second picture seems to be of an electric storage heater or Economy 7 *control panel* which turns the heating on and off...
As the pictures look like you have electric economy 7 rather than a gas fired heating system, your problem with low water pressure via the hot taps is deffo due to lack of head on the hot system caused by the fact that you live in a flat.
There are options available to you in the form of negative head pumps, but this will cost you and you will need to call in your local plumber to give you a deffo answer on this.
Everything is on the ground floor as it's a ground floor flat. It's in a cupboard right next to the bathroom with the shower the other side of the wall that the little box is though when they fitted a new shower (previous people put one too powerful in and it melted all the bits) he had to lay cables all the way down the hall.
the main problem is that cos its so low (ground level) gravity cant help pull the water through with any oommpphh! it must be pumped if you want it to come with any force.
Hopefully the Landlord's plumber is coming back soon to try and fit an electric radiator in the bathroom as there's an existing connection right up the wall which is just connected to a little blowy heater thing.
Needless to say, getting out of the shower in the current climate is an experience!
If the tank was put up in the attic, you would then have a *head* of pressure.. as it is, you need to pump the water upwards to the shower... so the shower is pathetic lol...
Just imagine you have a tank of water high above your head... imagine the force it exerts downwards... yep, you've got the idea !
