Plumbing Question

[x5x3]

I would appreciate people's thoughts on this - we bought a 3 Bar whole house twin pump recently (along with new bathrooms etc) and several people have said they are quite noisy - does anyone have experience of these?

Some brands are noisier than others. Also depends on where and how it is installed.

We've got a shower pump that is the airing/hot water tank cupboard which is in the kitchen.

It is noisy but you just get used to it. Actually our parrot, who lives in the kitchen, loves the noise

I have checked and it is a Salamander if that helps?

I am not convinced the extra pressure when you have a shower is worth the noise every time any tap is turned on?

We have a salemander pump, 3 bar i think.

Its running 2 showers and a hot tap in a sink.

When you turn the tap on you can hear the pump start up and carry on once the taps turned off, bit of a shame as they are supposed to be the best!!

Salamander ones tend to start leaking as they have plastic impeller housings, better to get one with a brass casing. Grundfos are the best imo http://www.inspirationsbathrooms.com/icat/range142... and yes they are noisy (all of them are)

I've got two Salamander pumps, and previously had Stuart Taylor pumps previously. ST are definitely better quality (brass v plastic), all were similar noise level.

What is your pump mounted on? Rubber feet and bolting to a heavy base will probably help.

All the ones I've seen have had a whiny buzzy noisy stty brush motor fitted, and predictably sound like an electric drill. If there is a model available with an induction motor then get that, it will only hum a bit. Bet there isn't though, because everything's cheaped-out st these days. Price these things go for vs. extra materials cost for an induction motor version, there's no excuse for it.

We considerd building ours into some sort of sound proof box type thing.

But my plumber mate said something about the heat may cause some problems?

They are all noisy unfortunately. Could you possibly audibly insulate the cupboard it is going in? Heat shouldn't be an issue then as it will probably be plonked next to the hot water cylinder anyway.

thanks all - I have been recommended as an alternative some kind of clever cylinder which somehow uses mains pressure for hot and cold? It is also stainless steel and has a 20 year guarantee - do these work?

How many Bathrooms do you have? If you are considering a cylinder swap, you may aswell go for a combination boiler, you will have high pressure hot water and it is heated on demand, so is much more efficient. Mains Pressure Hot Water Cylinders tend to only get installed in large houses with a high demand for hot water.

But yes they do work. Your cylinder at the moment is being fed from a cold water storage cistern, probably 1.5 metres at the most above the cylinder, which is why the pressure is so low. The mains pressure cylinder are filled directly from the mains and restricted to 3 bar (I think). You'll have the same pressure from the combination boiler, but you'll be heating up a large quantity of water as opposed to heating the amount you need on demand.

if I understood the plumber chap we spoke to correctly though the insulation on the new cylinders is so good the heated water lasts for days?

They are a lot better than conventional cylinders, but if you have a small property a combination boiler makes more sense.

knowing absouletly zero about this subject does not help but I have now found out we are being recommended a "megaflow" system?
