Advice about Triton T40i Shower Booster Pump

onedave

I am considering fitting a Triton T40i pump between a thermostaric shower bar valve and the shower head, to boost a rather low performance on a gravity fed shower over a bath. For various reasons I cannot fit a 'power' or electric shower, without extensive disruption. Can anyone pass on any comments they may have about how powerful these pumps are? I would say that the water pressure is on the low side of normal, and the hand shower on the bath mixer works adequately. Are they about as powerful as a good power shower, for example?

First of all I am assuming you have an electric shower not a mixer shower were the water is heated by a combi boiler. If you do have an electric shower then fitting a pump is a good idea, however if you only have lets say an 8.5kw shower then the only thing that will happen is that you will pump cold water faster into the shower unit, hence alls that will happen is the shower thermostat or manifold will not cope with the power to heat up the water quicker, so one of two things will happen, 1. fast cold water from shower. 2. You will end up turning the power down on the shower so that the water runs hot and then you are back to square one. You can only get a 9.5 10 or 10.5 kw shower if your power cable is at least 10mm and you have a larger fuse in your consumer unit.

Good morning: Two very useful guides are available from the Bathroom Manufacturers' Association.. http://www.bathroom-academy.co.uk/pdf/showercontrols.pdf
http://www.bathroom-academy.co.uk/pdf/domesticwater.pdf

Take a gander through these...you should be able to determine what is achievable with your current DHW system.

Thing is, that the heater works at ONE setting... the way it is hotter, or colder, is by limiting the flow across it... so you turn the heat up, and the flow slows (allowing it longer over the heat to warm up)... turn it down, and you get the water flowing across as quick as possible....

this may not be the case entirely, with every model, nor quite the way it works.

anyway... you can figure out if the water is quick by turning it to coldest... if it still trickles, i imagine you'd benefit from any pump...

you probably find that if you turn it up to hottest, it's a scorching trickle...
if there was more pressure, you could at least get the temperature you want, with more flow...
