low pressure query

TCPPC

hi,

I have a query on low water pressure.

Currently my house is are using an conventional system, where the cylinder is on the first floor next to the shower room.

The problem i have is the head pressure, as the cylinder is quite low, the hot pressure is very poor.

I have ask for advice, they have all given me several different scenario.

One is to fit a pump in, some say i can and some say i can't due to the air cupboard being too small. If I can then I would need to fit another water tank up in the loft as the water would feed out much quicker.

Another option i had is to raise the cylinder height which can get quite difficult due to space and i really don't want to move it to the loft.

Last options and the most expensive is changing it to a combi boiler, as the hot water feeds through the boiler so it is instantaneous. This is an area i want to explore but its a very expensive options. 2.5 - 3k. Which i am carefully thinking of getting a loan to cover this.

50 gallon water tank with a negative feed pump

Raising the tank per metre gives 0.1br increase, hardly worth the effort

You could try upsizing the pipe work, 28mm supplies from the tank ans cylinder would help with flow

andy,

upsizing the pipe work seems like a messy job i.e going through board etc
and it doesnt seem like a cheap options?

whats the different between a normal pump and a negative pump?

A larger tank coud easily be £500, Stuart turner negative head pump easily £350 plus fitting

TCPPC

is it better to get a Stuart turner negative head pump in the short term than getting a combi?

What kind of system do you have ?
Normal cylinder with a tank in the loft or a cylinder with a small header tank sat on top of it ?

TCPPC

the cylinder water tank is on the first floor inside the air cupboard right next to the shower.

there is additional black box which contain cold water in the loft

Then you don't want a neg head shower pump

TCPPC

so whats best, because im getting different option.

Would it be just better save 6 months and replace the old system to combi?

I just want good flow of hot and cold water for my shower.

You can't use a pump with a combi, the pump may empty the roof tank if it's not very big & you get a powerful pump, moving the cylinder into the roof will make the pressure worse not better, if you intend to fit a combi in 6 months then I don't see the point in fitting a pump
