PV Hot Water Controller

[Worcester]

Yes basically, at the simplisic level they are very similar, however the Immersun has roll-over / duel load facilities and timer controls also built in.

What are the timer controls for? I thought the idea was to dump all export generation into a water store instead of the grid?

Yep, however if the system isn't up to temperature by the end of day due to either usage or lack of sun, the the system can then control your normal (or backup source) of heating to provide the nescessary boost.

For example most of our oil customers switch their whole oil systems off from May to October, so rely on the immersion, and the ability for it to ensure that whatever the sun's output that day they have ho****er is invaluable. This is even more important if someone is at home during the day and so has some kind of existing 'base load' and also if they don't have a roof or capital enought to have installed a 4kWp system. So whatever the sun's output and your consumption you are ensured hot water at the cheapest possible cost, even if there hasn't been enough 'free'. To do this with other systems other systems would be far more complicated and far more costly in installtions / controls / eergy consumed.

Thanks Worcester, I see. So the Immersun system could be coupled with a gas boiler to give the necessary boost or top when needed?

ho****er

lol.

also, thanks for the info - after checking out all the options, we're signing up with Immersun as well.

 

[Worcester]

Don't know how the **'s got in there!! had to re-read it myself to see that it should have said hot water .

@Mr.Shing-A-Ling - yes that's possible

 

[Gavin A]

Well that was fairly painless. We're now listed on the Immersun as installers for Leeds.

@TonyGreen

4Eco / Immersun will only sell direct to Installers.
As an end user consumer, if you buy the unit only you will pay 20% VAT. If you have it supplied and installed, VAT will be at 5% as it is classed as a Hot Water Controller under the reduced VAT guidelines.
To find out your local installer, go to Where to Buy :: immerSUN :: Use 100% generated free electricity :: A 4eco Product
If you are in installer, then the Distributors listed here , will supply at the same trade price as 4ECO, and extend credir and other payment options to installers:

You should invest your money in a solar hot water system, in the form of tubes or flat plate. By the time you have spent approx £500 on PV heat dump, you could have saved £500 on a £3000 solar thermal set up!
The immersion heat dump is messing around with a piddley amount of energy during only peak times of day. Solar thermal is much more efficient for heating stored water, hands down!
With the PV, just use it as a cash cow like everyone else does, some electric is a nice bonus during production hours.

the problem with Solar Thermal, is that like most PV my roof is now covered, so with immersun I should be able to use the spare electricity.

By the way they now have a price on.

@TonyGreen that is a trade only price to Installers, Immersun / 4Eco Ltd to help the industry will only sell through distributors and Installers Have Spoken with the 'Green Electrician' and they also say that is the trade only price. They will supply to a consumer through their local sparks, - suggest that they should be VAT Regsitered, as supply is at 20% and under VAT Rules 708/6 para 2.6 these can be Supplied and Installed at 5% VAT

I really do wish these trade only online websites wouldn't broadcast their prices to all and sundry :banghead:

Surely can't be that hard to require a trade log-in to view prices now can it?

 

[Worcester]

@TonyGreen prices for installers had been 'outed' in the Sun Lounge a while ago, so wthose that needed to know could easily have found out. So long as you are a registered sparks and not a supplier, you can register to come in to the lounge - same rules as the Electiricans Arms.
