Domestic air source and cold callers

[addjunkie]

We went for 4 or 5 days with no electricity last winter. Luckily with the oil fired aga and woodburner we were fine.

We we 5 days with no ziggies last winter, and as the log burner heats the heating it has pumps….so-also need electric, bad planning that, Id not repeat it. But with the generator and air fryer we survived just fine.

Probably the same idiot telling me I was daft not to rip my oil, water tank and PV out to fit his gshp...
Obviously these people are getting customers tho..

One of our neighbours big old manse, grade 2 listed, last guy Mike, retired diplomat, eco warrior had a pellet boiler, cost a fortune, pretty stupid really as the wagon couldn't get close enough to blow the pellets into his hopper. New guy, just spent the last 7 months doing it up. Pellet boilers gone, has an ASHP from grant installed that has an oil boiler attached for when it cant cope. And log burners in several rooms. No additional insulation…..madness, all to do with the conservation folk, wasnt even allowed to replace rotten wood windows, with new wood windows with double glazed units. They had to be repaired.

I know the guy who supplied log burners and heating quite well, hes very happy.

This is whats stopping me putting the lounge log burner into the thermal store. In a power cut, the Rayburn will fill up the store. Its kinda fine as we can set it to cooker and not run it too hot and have a bath if the store gets very hot! But adding the log burner could be troublesome in the event of a power cut as we will need to use it to heat the room but wont want it heating the thermal store and it will be less controllable (in water terms) than the Rayburn.

we have a thermal store, heated by back boiler in the log burner, oil boiler, and solar pv. Boiler is closed system, back boiler open system with pumps through heat exchanger. If it fails it wont be replaced. Wouldn't do it if I had my time again, though it was a good idea at the time.

My CH boiler burst on the coldest day of last December, but I have a gas fire in the front room, and several blankets, so it was no great hardship for a few days until it was rebuilt.

Plus, I have one of those small portable gas heaters out in the shed. And an electric radiator thing in a box somewhere.

I'd never want to rely on single source of heat for the whole house.

Ours is setup so the oil boiler and the Rayburn are open. Boiler wont work in a powercut so that wont be a problem. The Rayburn is gravity feed so no pump needed therefore we still have hot water in a powercut but no central heating*). The pumps are for the boiler and central heating, with a third pump to send heat from the top of the store to the bottom if the top gets to 85C (this dissipates the heat and makes the central heating pump come on sooner. Its a clever setup. The central heating pump is designed to circulate when its thermostat kicks in (set at 55C in the winter) - as the Rayburn is on all the time, it makes sense to just constantly keep the house warm. Can ramp up or down circulation by loading the Rayburn or letting the fire die down a bit and slowing the burn. The oil boiler is for top ups if needed but we didnt turn it on at all last winter! My only criticism is that the store is probably a little small for the big bath with only the Rayburn heating it so we either need a 20 minute blast with the boiler to top the heat up or to add a second pre-heat tank to it. We didnt go larger as we didnt want to overdo the weight.

*not the biggest deal as the Rayburn and lounge log burner are fairly central in the house so only the bedrooms are cooler in a powercut and that just needs an extra duvet. One day i might run a lead so i can power the pumps with a generator if ever needed but its not a big deal.

We have the attachments to add solar water and there is an immersion fitted but not wired in so we could run that off of PV or mains if ever needed. The idea is to get the solar doing the work in the summer so we use less oil then.

There's a piece on the BBC website about Heat pumps.

Do you know who actually runs councils? Unelected civil servants who don't answer to anyone.
Blair gave them all loads of new powers years ago.
The elected councillors of whatever party have very little control and no experience of running billion £ budgets.

Don't wire in the immersion what ever you do. They use loads of electricity.

Thats only going on in an emergency or if we put PV panels on.

Ours is wired through a solar optimizer so if theres ziggies to export it midulates first the hitwater tank emersion, the. The heat store emersion. Using one of these

eddi solar power diverter | myenergi GB

eddi is the solar power diverter from myenergi that allows you to make the most of your self generated power!

Have generator c/o switch too, that allows us to plug in the generator, which will run everything in the house except the electric Arga, washer and tumble dryer

If the grid fails for a few days, my car will/would/could power the house. It is generally charged up to about 80%.

My 3kW diesel generator could supply the minimum household requirements and charge the car with excess generation if/when necessary.

The battery operated oil-fuelled air heater is yet another alternative energy supply for space-heating.

The gas system must be sustained - or the whole system would have to be shut down on safety grounds - with every consumer being individually reconnected by the supplier.

Is that enough alternatives?

with being a plumber id have 5 gate valves ready for use 2 to open a closed system up to a gravity fed system one to shut down the hot water cylinder the last 2 are a small tank feed return and supply

then i can run the rayburn as an open system or wood stove and have central heating on even in a power cut

the last pipe is also fitted with a gate valve and thats your overflow pipe to the tank

One benefit of the smart meter is dirt cheap power between 2 and 4am. That's when the immersion timer comes on.
I barely notice it on the bill.

I heard about this last night, almost unbelievable!
But unfortunately true

Idiots.

You missed my point? Methane to CO2 is the eventual conversion in the atmosphere. But, meanwhile, methane is a far more effective green-house gaz than carbon dioxide. Plastic waste needs to go somewher, so what would youndo with a filthy greatnpile of plastic waste? Think about it, and come up with a better answer?

Convert it to char?

Not sure I follow Gaz. The Rayburn flows to the thermal store via gravity. The store has a header tank and the water in it circulates through the Rayburn, boiler and central heating (CH when the pump is triggered). So the whole lot is an open system. If it boils (say in the event of a powercut) the store will vent to the header and then overflow. All we need to do to cool the store is damp the Rayburn down and run a bath.

if it was tee'ed off and went into the central heating system pipes with 2 gate valves within power cuts the gravity fed system would feed the central heating system

the gate valves would only be opened in this condition but must be closed if you want to close loop it again going through the boiler

but you need to close down the hot water cylinder return with another gate valve or equalise it like you do with a radiator system

the rest that you have already is piped up so no need to add them to an exisisting system

just incase your not sure about it any presure thats within a closed loop central heating system would eject itself out of the header tank over flow pipe

Hmmm. I'm no plumber but I cant see how that would work on my system. I could get it if you were suggesting leak off rads but not the whole system. To complicate it, half of my system if microbire off of some badly plumbed manifolds.

 

[gaz1]

a gravity fed system is the same as an open air system like the below system pic



the pump is there just for better flow on the feed pipes but a gravity fed system can run itself and feed the radiators just the same

sealed central heating systems dont use expansion tanks as they use boiler pressure and a pump to flow the heated water

so on the above pic remove the expansion pipe and the header tank feed that goes into the return pipe to the boiler and thats your sealed system
