Weird boiler setup in house

[Luke1976]

Hi All,
I have recently moved into a 4 bed house (standard terraced Victorian property with a loft conversion in the Kingston area). There are two showers - one in the loft and one on the first floor and radiators in each room.

There is a glow worm boiler in the kitchen (pic 6) which seems to have two valves fitted (pic 7) and an external thermostat (pic 8). There is also a button/panel which sometimes comes on (pic 8) - I am assuming this is an override switch or something.

In the loft there is what looks like a megaflow (pic 4) as well as an immersion heater or something (pic 2) and a pump (pic 3)

.

I don't understand why there are so many boilers and am wondering whether we can lose the setup in the loft as its bloody noisy and takes up a lot of room.

I've attached pictures, but if someone can explain why we have so many bits of kit that would be really handy - three plumbers have come out, scratched their heads and gone away again. One plumber came back and said there's nothing that can be done as it will be to do with low water pressure?

You have a hot water cylinder - stelflow
A glow worm boiler with 2 zone valves
And a booster for low water pressure -tws

There is no pic.8 and only one boiler. As to the rest of your Q`s I`ll leave that to others to walk you through what you have there.
Imersion heaters are useful when the gas boiler doesn`t want to play.

With two showers you’d be daft to do away with any of it. Looks a good choice set up

 

[Luke1976]

ok thanks scott_d and rpm - is it possible to shift the whole lot down to the kitchen somehow (ie getting a megaflow installed and swapping the mains shower in the loft for an electric shower)?

 

[Riley]

An electric shower will be noticeably worse performance wise

 

[Luke1976]

Thanks Riley

 

[Riley]

I would be more inclined to investigate sound proofing

 

[Luke1976]

That's an option Riley - or we could move this setup elsewhere? Is there an option to stuff everything in the kitchen and just have a pump in the loft? Or is this just going to be bloody expensive..

 

[Riley]

If you have the funds then you can do what ever you want but I wouldnt have thought moving that lot will be cheap. If you move the whole setup then performance at the showers will not suffer. Just FYI you cannot Put a pump on the set up you have

 

[Luke1976]

Ok no probs - so its not just a question of getting a bigger boiler to cope with two showers? Its just that our neighbours don't have a problem with low pressure so I'm wondering whether all this gear in the loft is just to feed the shower up there or whether it serves the whole house

 

[Riley]

It will give you a balanced hot and cold performance at every outlet I would imagine.

If you are talking the combi route they are not designed to run two showers at the same time and you would definitely not get as good a performance . The setup you currently have Will give you the best performance when running two or more outlets at that same time.
I guess the only other thing you could do would be to run a new water main in possibly from the road all the way to where the hot water cylinder is then you could do away with the booster cylinder

 

[Riley]

I think your best option is to engage the services of an experienced heating engineer who can come round and give you Options

 

[Luke1976]

Ok thanks Riley - can I just pick your brains about Megaflow units? Would one of these negate the need for the setup in the loft?

 

[Riley]

How do you mean?? Megaflow is a brand it’s another version of the RM Stelflow cylinder that you already have. Megaflow and RM are brands. A lot of builders call all unvented cylinders megaflow

 

[Riley]

Do you understand what you have currently??

 

[Luke1976]

Could we move the loft setup down to the kitchen to replace the combi boiler?

 

[Riley]

I am getting confused now you have a combi boiler as well

 

[Luke1976]

I think so - we have a combi in the kitchen which serves the hot water/CH and the setup in the loft fills the gap when water pressure fails - is this right or have i got it completely wrong?

 

[Luke1976]

the glow worm i the kitchen - is this not a combi boiler?

 

[Riley]

It could possibly be what model is the glowworm boiler I can’t make it out

 

[Luke1976]

I think its a 30C which says it is a combi boiler on their website. What kind of boiler would it be if it wasn't a combi?

 

[Luke1976]

Its a Glow Worm FlexiCom CX

 

[Riley]

Okay that is a combi boiler however it sounds like it’s been adapted to heat the hot water cylinder in the loft. We can work out what it feeds fairly simply. There should be five main copper pipes coming down from the bottom of the boiler from left to right it should be Flow, hot water, gas, cold water, return. I noticed from one of your pictures that the hot water pipe may well be capped off is that the case.

 

[Riley]

The simple answer is you need the boiler as this provides the heat source for the Stelflow to heat your hot water
