Thermal stores and solar

Give them a wide berth for the reasons you gave. I am pro this guy Rumm is an amateur. He ignores advice thinking he knows all the answers.

That is because you lack much knowlege of this topic. BTW, a cheap stainless unvented cylinder can be easily converted to a vented heat bank.

Nonsense. You never looked properly. Pure amateur. No idea.

In bullet form, what do have and what do you want to do?

How many bathoom? How many showers? UFH? Solar? Rads? Soild fuel boiler? etc etc

This man is a total idiot.

Pure madness.

For the 2nd time this century, drivel is right

Depends on what you compare against obviously... I got a quote for a DPS Pandora system (about £1,800 IIRC) which seemed rather pricey just for hot water (I have conventional rads, an no plans for UFH, so there is no benefit for running the heating side from a store)

Officialdom is no more or less than with a boiler or any other heating system change. In they all come under building regs these days.

Gimmy a few more days I I might be able to tell you!

Indeed it can - problem is cheap SS cylinders seem to cost much the same as an unvented cylinder. Then you need to add a few hundred for the extra stuff.

Unless all you want to do is get on a subsidy gravy train...

At other people's expense.

This proves you haven't clue about thermal storage, not understand the buffering qualities and advantages in boiler operation. I advise the OP to totally ignore you. DHW only stores can be bought for a fraction of the Pandora price.

Tripe!! The unvented cylinder has to be installed by an approved man - and they charge more. It also has top be serviced once a year - by an approved man - approx £1000 in servicing over 10 years while a thermal store costs zero. Waste your money by all means, but do not tell others to do the same.

Please do not, you haven't much of a clue.

Cheap SS cylinders and cheap unvented cylinder, even with the extras still means a cheap store.

All you had top(sic) do was to read something other than a catalogue. Sad you are and sad you will remain.

Bullshit as ever from you. All a thermal store needs to do is to store heat for about six hours run time, with the thermal mass that is already in my home from the one metre thick stone walls, there's not much need for more than the day-long insolation to provide the comfort level needed.

This man is a lunatic.

Cor blimey Guv, he spaketh some sense.

No it demonstrates that you are still stuck with 70's thinking, and have not thought through the implications of the solutions your recommend.

Buffering has little value on modern boilers. What are you hoping to achieve?

When you can get seasonally adjusted (real) efficiencies up in the mid

Why not let him thin for himself?

Link?

By the same logic the boiler has to be installed by an "approved man". Installing a thermal store also requires aforementioned approved man or a building notice the same as any other cylinder change.

Manufacturers of modern boilers also recommend annual services - so even if you are proposing to pay for that, get the cylinder done at the same time.

Since this is DIY group however its rather a moot point.

Have you actually looked at the servicing requirements for a cylinder? They are simple enough that even you could probably manage it.

and again in English?
