Barking mad.
I need to read in more detail, but there are major issues that are seemingly ignored.
Install a heatpump, running off electricity, which pays back after (say) 10 years, and continues using fossil fuels thereafter, and which will need (likely) a major refurbishment or replacement costing several thousand pounds in 15 or 20 years at most.

Versus installing insulation to harder to insulate properties, which is in many cases unsubsidised, and could provide lasting savings for the life of the structure.

Then there are the major issues around 'certified' kit being enormously more expensive than that available retail.

I note I paid around 400 total for a 1.5kW solar-thermal array.
For MCS approved - this easily adds another zero on.

This is looking like the enormously expensive FIT debacle again.

Hi

What 1.5kW.t system do you have ? .... I was under the impression that £400 would just about be a reasonable cost for a small DIY panel but wouldn't cover controller, pipework, pump, cylinder/cylinder coil, sensors, connectors, wiring, antifreeze, expansion vessel ... then there's the scaffolding and the pipe insulation and the roofbolts, the labour and .....

Here are some kits and prices. Personally I've run out of room, and have a combi. Oh well!

Hi

Thought that £400 was a little low, even for DIY ....

so will a wood pellet boiler be wa wothwhile investment over say 20 years or not

confused or what?

How long before the 'Cowboys' currently selling inflated price solar PV installations move in to this area?

They'll have to be very creative with the figures! (not that that will stop them).

My proposed system solar thermal system came in at £6.2k, with, iirc, a one-off £300 premium payment and, according to the consultation document, a rhi annual payment of about £120, making resonable assumptions.

I wonder if, unlike the fit, many will be put off saving the planet by the low cash returns from solar thermal?

Hi

What spec system would the £6.2k provide ? ... seems expensive, but I also had quotations at well above this level ...

The main issue, as I see it, with the RHI is that the unmetered payments would be based on the estimate on the MCS certificate which is based on a flawed BRE hot water provision calculation (BRE flawed calculation ? ... where have I seen that written before ... ) ... it simply seems that no matter what technology you have on the roof, or what size it is, the amount of hot water it can provide is limited to a percentage of the assessed hot water usage demand for the property according to BRE .... (Just knowing this, I'm not sure whether I need to get a new life or the BRE need to get new people endowed with a little common-sense ... but I'll hazard a guess ... )

why is the incentive figure so much lower for biomass

this is really the only clear option for me to replace oil but may not bother now

there is a new system using an aluminium on roof panel, through which a refrigerant gas is run, that will provide 100% of the hot water needs.

The price is similar to conventional solar thermal, about £ 5,000, but the performance much better as the existing technology delivers 70% of hot water requirements over the year, AT BEST.
