Hi All,
Recently moved into a new house which does not have a Bath and has really poor hot water pressure upstairs. The system is gravity fed and the issue arises because of the minimal head between the cold water tanks (in the loft) and the HW Cylinder/taps upstairs.
Will be re-doing the bathroom, which includes installing a bath.
Current shower is boosted by a MIRA Power Shower, which provides sufficient pressure.
The Hot Water tap in the bathroom is the main issue as it just dribbles and when I install a bath it would take forever to fill it with similar water pressure.
PLEASE SEE ATTACHED DIAGRAM.
I have thought of 4 options, in order of preference. I also have included some questions within the options.
1) PUMP UNDER BATH
This will provide pressure to everything in the bathroom. I propose just feeding HW and CW pipes that currently go into the bathroom, directly into the pump and then outputting as required.
I fear that this solution is probably a bit controversial for 2 reasons. Firstly, there is no surrey flange mentioned but I don't understand why this is needed when the MIRA power shower was professionally installed without a surrey flange and has worked fine for over 5 years (with previous owners). Also, I assume when I run the kitchen tap (same pipe run) the pump might try to kick in but then stall.....however couldn't I just install a 1 way valve at the point before the pump to prevent this?
2) SURREY FLANGE WITH PUMP TO PUMP ALL HOT WATER PIPES
My issue here is that I have a MIRA power shower in the downstairs toilet. I wouldn't want to change this. Plus, downstairs water pressure is fine.
3) SURREY FLANGE (PUMP IN AIRING CUPBOARD) WITH NEW PIPEWORK TO BATHROOM ONLY
This seems like a lot of work and how would I pump cold water without making a new hole in the cold water tanks in the loft?
4) MAINS COLD WATER
To combat the above problem I could hook up the cold water to all be mains fed. I don't like this idea as it makes the 2 tanks in the loft redundant and negates some of the benfits of having cold water tanks.
Any help/comments much appreciated.
Happy new year everyone
