I asked the builder and their response is that the idea that underfloor heating is better is a matter of opinion, and that they value responsiveness - basically a radiator valve will manage the heat in a room quicker than underfloor can manage. The Vaillant heat pump is described as low-medium...

Ok, when I say "the builder has specified" I don't know who exactly it was. It's in the house spec, in any case. It's a development of 19 properties, so I assume there were specialists involved somewhere. I did wonder how a heat pump was going to get up to 75⁰C without being effectively just...

I'm looking at a new build bungalow, and the builder has specified a Vaillant Arotherm Plus heat pump and CenterRad compact radiators. The heat pump spec claims 75⁰C output, and therefore it can drive radiators, but that feels to me like it's designed to retrofit into older properties. I would...

I have a shower with a 15mm chrome riser pipe up to a waterfall type head. I want to cut into the riser and add a diverter valve that will feed a regular shower head, because I don't want to replace the whole riser. Problem is that I can't find a diverter valve with 15mm fittings. Does such a...

I want to replace some leaking lockshield valves. The pipe comes out the wall horizontally, which is a pain since a normal lockshield will end up sticking out into the room. The best option I can find is Danfoss RLV-D or RLV-S because there's no handle to stick out. Problem is, I don't know...

Yes, the 230V supply may be connected off-diagram to the common terminal of the switch. But I'd expect it to have a removable link at the connector strip in that case. The external programmer has the option of 230V or voltage-free to suit the boiler, so one approach is the start with...

Hi. I have a Vokera Compact 28 where the manual timeclock's auto setting doesn't seem to be working, and it is always on. Rather than try to fix it I'd prefer to go with a new external controller, and the current favourite is the Salus RT510RF+. What isn't clear is if the switch circuit should...

Thanks. If I used something like leadmate could I basically stick those to the valley? Otherwise I guess it means removing a couple of tiles on each side for the full length of the valleys (there are four) and nailing these onto the battens. Which ends up being a fair bit of work, but maybe...

Looks like double romans. They are relatively high above the evalley so the rounded profile allows that bit too much space.

The tiles that border our valley gutters have a sizeable gap under them. They are not mortared. There's enough space in there for birds to nest, which is not ideal, so I want to fill the gap with mortar. Is it OK to first put some expanding foam in there as a backing? Otherwise it's going to...

The panel has a list of contacts, including email addresses. It seemed logical that a test of email would be to send something to each of the contacts to verify that they all work. And if would be even more logical if the manual said what was actually being entered on the keypad at the email...

Progress! I was using the test menu to get email to work. The manuals don't say what should be entered on the keypad at this point - turns out it has to be an email address. I thought it would just be a bit of text that would be sent to the contacts list.

The major challenge now is getting email to work. My god this stuff is crap! I run my own email server, and have set up email accounts for many people over many years. But I just cannot get this panel to send an email. Does anyone know which email provider works with these panels? I've...

Further experiments: I can log in as a different user if I just use the appropriate code. So I reckon I have all I need to get to the installer side of things. But it's still not on port 80. That doesn't matter, now that I know how it seems to work, but the manual is deeply unhelpful on this.

I have just finished installing an i-on40H and all appears to be well, except I can't access the web server. I have enabled remote access, and the web server is enabled. The panel is connected to the router, and it has an IP address. I haven't changed the port number. If I try to access the...
