New build underground gas duct to meter box

[ruggers]

I've laid my 63mm underground yellow gas duct for a new build and i have it coming from horixontal underground with a sweeping bend up vertically to the hole under the built in external meter box.

 

The electric one has a red and white hockey stick to complete the transition between duct and meter box, but i cant see anything online for the same with gas.

 

Looking at completed wall boxes on neighbour’s houses they just have a white plastic conduit coming out the bottom of the gas meter box into the ground.

 

Does the gas company provide this?

 

Is there a coupling for the 63mm to stick?

 

Hoping to not have to dig down through comlacted type 1 to add a plast sweeping bend when the yellow duct already does this with the draw cord in.

Sorry not answering your question - but more or an observation.

 

Why are you installing gas on a new build? Install a heat pump and save your self a fortune in running costs. Add a battery/PV and save more.

 

Our new build was completed in 2021, with gas boiler. After a year or so fully optimising how it it ran, I added an ASHP specifically for cooling the floor. Operated a hybrid system. Realised, with standby charge for gas and the great cop from a heat pump, the boiler had to go. Since added more PV and battery and pay almost nothing for energy even in NE Scotland.  Gas it last century.

Yes, I think the current rule of thumb is to keep gas or oil if already in place but use ashp if all new.

That may change according to what happens re the Iran situation.

 

But putting in a gas pipe just in case makes some sense. Have you laid the yellow warning tape above it in the trench?

If in doubt, bring it through a 110mm pipe bend and close both off with plastic and sticky tape.

I'm on the old 2022 regs so i can choose gas or electric heating, solar is a choice and overheating hasnt came in by then.

 

The yellow duct has been in place for over a year, it just comes up from 600mm below to up against the wall. Its £290 to get connected.

2021 wasn't last century 😂.

For what it costs i just want to run gas in. I wish there were more gas ashp hybrid units.

 

Ashp wont save me any more theyre almost identical in running costs I've been going over it for years and nothings changed. Its a total nightmare i hate heat pumps and battery and solar before I've even lived in the house.

Tempted to sell it at the end and stay in an old house with gas combi and not have to monitor how much water i use and pausing heating because its 4pm to 7pm peak rate.

 

I'm just going round in circles with it and over the 4 years I've been told heat pumps are the future and the prices will come down, they've just increased by 15%

 

I'll likely have to fit an ashp to handle the low peoperty heat loss and minimise short cycling better than gas but i really dont want one. It just means the battery situation becomes twice as expensive so not woerh it for me.

 

I've put 4.8kw of South facing solar on, thats the most i can put on the roof. Battery adds 2 grand, or 3 grand if i add the gateway for off grid back up. Due to my low usage I'd save £220 a yr using octopus cosy, thats not a big enough saving for a decent roi.

 

Cant get on anything cheaper than cosy without an EV which i wont be buying. EV is the only way to make a battery roi by unlocking super off peak rates.

 

The idea of having weather compensated heating is to let it run 24/7 and have a nice steady comfortable house, but energy prices on tou tariffs just goes against it all and makes us run sumilar to on off if we're having to use set backs in the peak slots. If electric cost 4p per kwh, we'd just run it as we please.

 

My price was for a 9.4kwh battery which is enough for my house, but add an ashp, then i need twice as much battery, so twice as much outlay, which still doesnt help the roi. Cycling a smaller 9.4kwh  multiple times ler day just halfs its life span

 

If you have an EV and can stick 10kw+ of panels on the roof and install a battery yourself then its all good.

 

Solar doesnt help a heat pump when you need it in winter. In summer you only need to heat dhw. Solar diverts a waste of money if you can export for 12 to 16p per kwh, its better to heat dhw quicker and more efficiently with the ashp in summer.

 

I'd need a scop of 4.15 to equal my 90% efficient gas price vs 25p standard electric cost.

 

Cosy off peak 14.5p

 

Ashp is average scop 4, so its 400% efficient, but Gas heats is 4x cheaper  and heats dhw 3x faster at any outdoor temperature and due to the cost, you can just set water constant 24 hrs a day and not worry about tou cheap slots. We like 10 minute showers, 3 of them and the tanks nearly empty.

 

Engineers charge £100 more for a heat pump service vs gas which wipes out the annual savings.

 

Will an outdoor heat pump exposed to the elements last as long as an indoor gas boiler?

 

Same brand boilers 12 yr warranty vs heat pumps 7yrs. The manufactures cant have faith in the product.

 

The only reason I'll end up installing an ashp, is if it will run a low heat loss property better than a viessmann 200 11kw boiler at its lowest modulation of circa 2kw. But most heat pumps ive seen are 2.1kw min output too.
