As I have been for the last 10 days since the immersion heater died! It’s not quite so good for washing hands though…

On cost and the wider considerations of whether this would be worth it: My initial post was intended to figure out whether this was possible, electrically. As a number of you mention, the cost of replacing the cylinder entirely probably needs to be weighed up against any tangible benefit to me...

Thanks for all these replies, very informative stuff. @ericmark I'd seen a few of your posts about the Willis system - these are interesting. You're right in that it's probably worth me weighing the cost of changing the whole cylinder vs the potential savings (which are likely to be minimal) by...

The plan (or at least, the idea I was exploring) is to replace the existing tank with a twin element unit. I'm not on E7 at the moment (I was) but on Octopus Agile - which is similar in that it has low rates during the night (and for most of the day) but much higher during peak times. The...

Current cylinder is a single top entry immersion element, and it’s wide on a simple manual time clock

The instructions for the following unit actually seem to suggest that it would not be possible to run the two elements at the same time, My fears of potentially overloading shouldn’t be a problem. https://www.tlc-direct.co.uk/Products/SMTRTM7N.html Thanks for your help

Seems to be the norm for E7 cylinders. Bottom unit operates at night to heat whole tank, and if needed to top up during the day (e.g Mrs has a bath) I don't need to heat the whole tank, so just use the top element to heat the top part to get through the washing up. Inefficient turning on a...

Yeah, basically cheap rate at night. Okay, that timer (or similar) looks like an option - thanks. It's not explicit in stating that the boost element would automatically turn off when the normal element turns on, though. Although the setting of the boost time should help in that respect.

I have Octopus Agile (but was on Economy 7, and use it to heat water at night). So there is no issue running both immersion elements off the same circuit, provided they're controlled not to come on at the same time? Am I right in my assumption that I definitely could not run both at the same...

(Disclaimer, I am in no way a qualified electrician and will get someone to look at/do this for me. Just trying to work out what the best approach is). I'm wondering if I can run two immersion heater elements (3kW each, so 12.5A each) on the same circuit? Getting another circuit upstairs will...

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...

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...

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...

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...

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

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...

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...

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...

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...

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...
