The big phone switch over/off in 2025
dpmiller replied to Temp's topic in Networks, AV, Security & Automation
For now, BT still cling onto the old geographic rules. One of the reasons I went 4g was that with VOIP I could retain the number, whereas BT refused to let the number even move between sub-exchanges in the same main exchange group. Irony is, now that the number is ported to voip, it could in the future be ported back to BT *anywhere* in the UK... -
The big phone switch over/off in 2025
dpmiller replied to Temp's topic in Networks, AV, Security & Automation
openreach no longer offer copper at either of our local exchanges and fibre is looked after by a 3rd party who hasn't completely trunked our road yet. Plus, fibre installs are subsidised under Project Stratum but the area was surveyed prior to our build So 4g it is, for us. the router and voip box are both on UPS, and my old landline number is now safely transferred to VOIP and in my ownership -
UFH - zone not heating up. No flow...
dpmiller replied to Newbuildnewbie's topic in Underfloor Heating
flow gauges act as a coarse NRV do they not? -
NTC sensor + 8m of cable = profit. / in other words, just extend the cable...
-
why not tho? Seemed like a no-brainer as the wiring was going past a zero-volt relay contact... /if it does ever go off at least I know the emptied property is being purged.

@JohnMo I never said anything about staying in the house...

On the fire/ smoke side of things, will the Aicos all be wired interlinked or will you be having any on wireless? Do you have any need for CO monitoring? gas hob/ woodburner/ whatever? Whilst we're on wireless, I've used an Ei414 fire alarm interface for two functions- MVHR off during fire alerts MVHR boost during CO alerts.

Enclosing hot water cylinder stat in insulation?
dpmiller replied to andyscotland's topic in Boilers & Hot Water Tanks
the temperature calibration will alter a wee bit, but as the cylinder isn't running too hot and there's no big current being switched there's no safety implication IMHO -
^ to avoid any ambiguity, @Conor has a sensor in the buffer that was supplied with the ASHP, some brands don't have this option. I'd suggest if you want to have a thermostat on the buffer, simply putting it in series with the demand signal from the wiring centre might work for your case? If either heat demand or buffer are satisfied the the ASHP will be commanded off, and it'll only come back on again if you still need more heat *and* the buffer has cooled.

thanks guys. @nod Blackstone or Ironwax Gloss?

if we knew what it was then...

anyone? @PeterW @nod

Which ASHPs are more prone to defrost cycles
dpmiller replied to Steve W's topic in Air Source Heat Pumps (ASHP)
they defrost when they need to. If it's iced up sufficiently that the fan can't pull fresh air through, it needs a defrost. Simples. You absolutely *can* get your LWT over 45c, but you'll need to reduce your energy demand to allow it to happen... / I can make mine ice up and need defrosts at around the same intervals, yes. But only by starting it from a cold house, in DHW mode, but leaving the CH circuits open too. -
what's wrong with the stuff you've already got, it's just the same?
-
you might need to lever pretty hard to get the horizontal to pull from the vertical post the first time- they're generally held by an O-ring or two and often a split steel ring. This is sprung, and may have eaten into the hole in the horizontal bar somewhat, taking more force to get it to pop over that lip

High boiler modulation after pressure loss
dpmiller replied to Adsibob's topic in Boilers & Hot Water Tanks
no you could dose the sealant in there -
Which ASHPs are more prone to defrost cycles
dpmiller replied to Steve W's topic in Air Source Heat Pumps (ASHP)
never mind all the SCOP numbers, how many kW is it actually rated for at the temp and flow? -
So I've got some nice black limetone slabs that will be used as a hearth. Looking to get at least one coat of sealant on before laying, but does anyone have any recommendations for a really glossy wet-look finish? Thompsons Wet Look paving seal seems like a possibility (supplier-recommended) tho in the past I'd probably have ladled on good old Klear. Any other thoughts? edit: Should add, it's a riven surface, not smooth

dpmiller replied to Steve W's topic in Air Source Heat Pumps (ASHP)
what schedule is the heating on? 24/7 or something less? -
WiFi repeater over ethernet
dpmiller replied to Carrerahill's topic in Networks, AV, Security & Automation
repurposed routers here. Huawei 4g modem/router covers one end of the house , then an old Talktalk hub does the other, and a Draytek out in the garage. They're all joined together (along with all the house cat5 points) by a dumb switch in the plant room. -
Are these costs realistic for a 500m2 house
dpmiller replied to miike's topic in General Self Build & DIY Discussion
respectfully, if you're building YOUR house for YOU to live in, what the hell has the value or brand of kitchen appliances got to do with it?
