Shower...my options..?

[xr4x4]

Hello all,

Will be soon moving in to propery which I will be doing the bathroom.

I'd like a decent shower but unsure of my options and need ideas.

Currently has a 8.5kw shower, due to the extremely hard water and just being a electric shower, it's pretty crap.

House had cold mains only to bathroom on ground floor, no cold water tank.

It has a hot water cylinder on the first floor, this has a combined cold water tank (on top) to fed the hot water tank, can't remember the type. This feeds hot taps only.

Price will be factor of course, so options.

Bigger electric shower.. Not keen.
Fit a cold water tank and go gravity pumped..
Pump the hot only, use mains cold and a balancing valve? Not sure if it will work.
Fit a heat plate exchanger to boiler and use mains hot.

What you people think?

Cheers.

may be time to fit a combi? with only one bathroom its quite logical.

Can't justify that cost as the boiler is working fine.

cost to run electric shower. ching

cost to install break tank and pump. and run hot water store for years to come. ching

install modern efficient combi, pay only for what you use. profit.

do you catch my drift? I'm not trying to say your absolutely wrong but I do hope you can see my logic.

How about a digital shower?

i like those showers, they work surprisingly well..

however i dont think they work on mains cold + gravity hw.

maybe a venturi shower? Ive never fitted one personally...but they are designed for this scenario

oh the trevi boost...

I have fitted only one, and it worked but it was awkward to get right, the pipe sizes have to be right and the water temperature has to be high enough.

but when the conditions were right I thought it did a pretty good job.

I'd go trevi boost providing your mains pressures ok, But not on a combination cylinder.

But not on a combination cylinder.

As a matter of interest, why not?

It's a vented hot water cylinder, so gravity hot.

I'm guessing because of the small cold water storage tank built in.

What about something like this?

Im sure I could do this, only thing that worrys me is the delay in hot water warm up time if the boilers been off and cold, ie in the summer.

From turning on the shower, the boilers got to heat the water in the boiler, (which wont be to bad as will be close to the boiler) pump it to the plate exchanger, transfer it to the hot water and then flow to the shower.

how big is your boiler then? plate hex will need 20kw min for something midly average/poor. Venturi shower has has to be the easiest and cheapest option
