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

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

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? -
so remember all that this is NI, we're still on the OLD regs, and check reveals are a must...

Ufh manifold, blending valve with ASHP.
dpmiller replied to Russell griffiths's topic in Underfloor Heating
an IVAR pump? do they make them themselves or just reprice and rebrand? -
Which ASHPs are more prone to defrost cycles
dpmiller replied to Steve W's topic in Air Source Heat Pumps (ASHP)
well that's exactly the conditions when defrosting will be needed so... How badly frosted-up does it look each time? Is there an external air temp sensor on the back of the unit near the fins that's getting iced-up? Are the external and unit temperatures displayed plausible? Can't say about other brands but the Engineering menu on our CoolEnergy unit will allow sensor calibration, time between defrosts, plus various duration/pressure/temp settings specifically for defrost. Our environment sounds pretty similar to yours and I'd see a defrost about every 40-50 mins worst-case. -
It is. You are polluting unnecessarily. It's only a matter of time before both smoking and non-DPF'd diesels are banned 🙂

@SteamyTea are you a smoker?

@Shaun McD you shouldn't have any issues with Kudos, I'd say they're on a par with MBC based on the quotes, spec, and meetings I had back before we began. / we ended up going with Leadon's tho as being the best price vs spec option...

Flush pipe keeps leaking due to un-even floor
dpmiller replied to Dan1983's topic in General Plumbing
isn't a flush pipe normally 38mm? sounds like your flexy pipe will be loose in the back of the pan surely -
Our TF guys had no issues putting the sole plate onto quinnlites.
