getting that glazing bar at the right height can reduce costs too as it can allow a downgrade in the glass above it. Our archtect designed this into our large front windows.

blue square thing looks like a transit foam that hasn't been removed from the unit?

Our Bronpi does the same kind of thing occasionally, I think the term is "cold plug". Gotta use a bigger than expected starter to get things moving.

might the second link be a wax finish?

Do you really need a Radon survey? Look at the map yourself and see what the risk level is first...

B&Q manage to get ex-tradies with *some* level of knowledge, to assist the punters

add another rubber washer

I'd presume it was above FFL but hang on for confirmation...

you've sorted the loose seam in the asphalt yes?

The Excise boys are pretty active this side of the Irish Sea- North and South- and it's not unusual to see main roads stopped for fuel checkpoints. Where I get red at the pump for the digger, and for testing heaters and things, there is a constant stream of pretty new snazzy cars filling up at the pump. Often tradies that are working daily on a site some distance from home. Seems the losing the car and being find isn't enough of a dis-incentive? A couple of litres for a digger or dumper aint even on the radar...

so have you confirmed that it's even a septic system and not just a leaky cesspit?

surely a cesspit doesn't have any outlet?

still available at the pump, locally.

we had similar to contend with, swan-neck did the job fine

put a radiolink into one of the Aicos to make the whole system accessible, then get a relay box or better still the EI414 alarm interface.

the pre- sown weeds and haz waste residue are free!

Coolenergy pumps are OEM'd by Sprsun. They may brand for other retailers too. You'll not find too many similarities with the big brands as Sprsun use a suite of control gear from Carel whereas Panasonic, Samsung etc do it all in-house

Walabot might do it?

^ like @Temp we find that smart placing of the controls/sensors allows a TS to recover before it runs out of heat, allowing continuous drawoff. And we're on an ASHP...

just be mindful that some have quite a fine mesh grille that you'll need to access and clean, if you don't remove it beforehand...

Willis is a Belfast company... https://willis-heating.com/about/

worth pointing out that this side of the Irish Sea, the Willis heater attached to a vented cylinder achieves superb stratification and allows continuous flow at reasonable rates. Heck, in our last house prior to fitting an electric shower we happily showered using the Willis- turn it on for a couple of minutes to get convection going and cap the top of the tank, then you could draw hot continuously at the rates allowed by the small shower heads of the day

Monoblock into 270l store, input and DHW coils both corrugated high-recovery, 3m2 area. Reheats til the thermistor halfway down the tank hits 50 so flow (and the top of the tank) are about 5c higher. That allows a shower before recovery, recovery takes 30 mins or so, but the ASHP ramps up quick enough that flow can be sustained near indefinitely at reasonable flow rates. All heating flow passes through the TS as a buffer volume too, so the whole volume of water rarely drops below 40c during the heating season. PV diverter and woodstove assist in adding energy when possible also Can't be precise about COP as I don't have energy measurement, but the highest daily consumption I've ever seen for the ASHP in the depths of winter is just over 30kWh; our monthly electric bill for the whole house (240m2) all-in is about the same as the oil usage in our previous little bungalow as most of the heating is accomplished during the E7 period 🙂

yep, ASHP/TS works for us

might the strainer in the PRV be blocked?
