    HW Cylinder (vented): Combination cylinder or not?

    Very fair point. It might be that the existing electric shower is just plain broken (I only bought the place recently and don't know when it was installed), but as it stands when I have the electric shower (one of these) on the "eco" power mode (4.5 kW), the flow rate coming out of it is...

    HW Cylinder (vented): Combination cylinder or not?

    Thanks both. Been through the whole rigmarole with Thames water. They measured outside the block of flats, and got a decent flow (~25 l/m) but fairly low pressure (around 1.7 bar). By the time it's up to my kitchen (2nd floor of the building) it's around 5-6 l/m at 0.7 - 1 bar (static - not...

    HW Cylinder (vented): Combination cylinder or not?

    Hi. I live in a split level 2 bed flat, there's a big CWS tank and a vented HW cylinder in the spare room upstairs. These feed the taps in the upstairs bathroom and hot water to the kitchen via a Salamander pump. Shower is an electric unit run off the mains, which has very low flow (at best...

    Gap Between Window and Frame - One Side of Window Only

    I've noticed that there's a gap letting a draught in on one vertical side of my top-hung window. The seals are tight at the top, left side and bottom. The gap is largest at the middle of the right hand side of the window (which meets the central mullion) but closes at the top/bottom - kind of...

    Window Frame/Reveal Refurb

    That's great. Thanks very much for the quick reply.

    Window Frame/Reveal Refurb

    I recently moved into a new flat and all of the windows need tidying up where sealant is peeling off, paint is cracking etc. Starting with the spare room. I'm a novice, so this might be the first of a few posts, but I have done a fair bit of research. Have attached a few photos below with some...

    Electric shower and toilet both run from CWS with same pipe

    Hi, I currently have an electric shower fed from the mains. Mains flow is terrible (same in my whole building), so have been looking at electric showers with built-in pumps which would be fed from the cold water storage tank. CWS also feeds the other outlets upstairs via a Salamander pump. The...

    Mixing 22mm and 15mm in a pumped system (whole house)

    Yeah, I was thinking something like this: https://www.mirashowers.co.uk/showers/electric-showers/mira-elite-se-98kw/ from the tank. Probably the least work, and relatively cheap compared to pumps etc. Was just hoping that while I was upgrading the pump I could add the benefits to the shower...

    Mixing 22mm and 15mm in a pumped system (whole house)

    Current pump does hot and cold water to taps and shower over bath. I did just talk to Stuart Turner and they've said that I wouldn't be able to run a twin pump to the shower as running only one side of the pump for long periods of time could damage it. So it'd have to be a separate pump for...

    Mixing 22mm and 15mm in a pumped system (whole house)

    Just checked this morning at around 7:45 (so a bit more "peak" time). Cold: 4.4lm Normal shower temp: 2.75 l/m It would be a squeeze, but possibly could fit in the space where the pipes run behind the toilet before going up to the shower itself. Assume you mean an inline thing like this...

    Mixing 22mm and 15mm in a pumped system (whole house)

    I have no idea how old, it was installed before I bought the property. I am pretty sure the bathroom was done fairly recently before the property was sold though - it all looked pretty new when I moved in (at the start of the year). As far as I know the shower is all original and the diffuser...

    Mixing 22mm and 15mm in a pumped system (whole house)

    Sorry wasn't clear, the shower has 3 heating power settings (high, eco, low). By turning down I meant with the power on high and the temperature control turned right down (which increases the flow out of the unit (while decreasing the temperature, obviously)). It does 5 litres a minute with it...

    Mixing 22mm and 15mm in a pumped system (whole house)

    The water gets plenty hot, absolutely scalding on the "high" mode. Even when turned down all the way. Same flows with the shower head off and just the hose. I will add that the pressure has been so bad in the morning at times that the shower won't even turn on. Everyone on the upper floors of...

    Mixing 22mm and 15mm in a pumped system (whole house)

    Fully cold, measured just now, ~5.5l/m. When turned on to a normal shower temperature it was around 3.3 l/m. Noting this is in the middle of the day. During the peak morning hours the flow is quite a lot lower. A test I did a few weeks back was around 2.4l/m when taken in the morning. The...

    Mixing 22mm and 15mm in a pumped system (whole house)

    Fair enough. I mean, really, the pressure is a big part of the problem. It's barely enough to rinse soap off! As for the 0.2, good question. It wasn't measured - I think someone said it must be around that on the basis of it being ~0.7 at the kitchen tap downstairs, so 5m or so of drop off. So...

    Mixing 22mm and 15mm in a pumped system (whole house)

    Hi. I have a property with a traditional gravity-fed system, with bathroom taps running off an old salamander pump with 22mm pipe. The electric shower runs from mains and pressure/flow is abysmal (we’re talking less than 3 l/m and something around 0.2 bar). I was hoping to upgrade the pump...

    Low incoming flow/pressure. Stick with vented, or boost pressure to unvented?

    Interesting, thanks for that. I didn't know if you'd be able to pump into an electric shower? I think my current electric shower takes mains only: a 9 kW Mira. I should add that the 2.5l/m was with the shower set to Eco mode and the temperature turned up about half way. With the shower set to...

    Low incoming flow/pressure. Stick with vented, or boost pressure to unvented?

    Hi. Yeah, it's a salamander CT Force 15TU, pumps both hot and cold to taps and the shower over bath. Not sure if an installation problem, but it's very loud - can be heard throughout the building. The flow from it is fair, but takes a while to kick in sometimes and could be better. Stupid...

    Low incoming flow/pressure. Stick with vented, or boost pressure to unvented?

    A follow on from a previous post. I have now established that the incoming water pressure/flow rate cannot be increased to my flat. A common problem in this development. The incoming pressure entering my property is ~1 bar and 5 l/m - this is at ground floor. Currently have an electric shower...

    Boosting pressure for unvented cylinder (or stick to vented...)

    Cheers. There are actually 3: The Thames Water one outside at the meter down a manhole; one at the ground floor in the corridor of the block of flats; and the one in my flat. The TW guy checked out the one outside and it seemed okay to him. I had a go with the one in my flat and seems fine...
