Lower hot water pressure

Xcellor

The hot water pressure in my home is not great... Two story house with water tank in attic.

Is the only option to raise the water tank or could I install a waterproof pump inside the water tank (to dampen noise) and then connect this with outflow pipe?

blah

My understanding is that you install a pump outside of the tank, and a good pump should be very quiet.

I have the same issue as you, even when having the heating on means I have a full tank of hot water, I still use my electric shower because the hot water pressure is so low.

One of the issues with a pump for hot water is that it's easy to use up the water quickly.

This would be better in the plumbing section rather than diy

Yes you can use a submersible pump in the attic tank. You can also use a stand alone pump in the hot press.
Don't forget that if you pump everything coming from the attic tank you will hear the pump if you flush the toilet at 4am.

Have it on a timer from 11pm-7am.
If you fit a submersible pump into the tank then you'll be fully pressurising the plumbing system, and in turn, will have to change the cylinder to the unvented type.

M.T.D

The upstairs hot and cold will be from the same attic tank.
Is it just the hot that is low pressure or the cold as well?

I've heard a lot of people moan about the noise at night. I've never thought to suggest a timer.

Ye it's handy. A standard atp timer. Assuming it's a postiive head pump then that means toilets will refill without the pump and taps will work in unsociable hours.

In the middle of renovation at the minute and our plumber was a mine of information. I told him I wanted two decent shower systems, one electric and one pumped. He said I would be better pressurising the whole system. He fitted an Aqualisa pump in the hotpress (neatly on the floor area) and it gives us brilliant pressure in the tank/hot water feed throughout the house.

At the pump in the hotpress he is fitting a switch to be able to turn off the pump at night so if somebody gets up during the night to use the loo the pump won't kick in and wake anybody. He said the natural pressure from the tank above would be fine to fill the cistern again with the pump off.

Works a treat!
