Thermodynamics and MHI
I have solar panels and get the FIT. A good little earner so far. Solar panel company has sent me info promoting thermodynamics, it will produce all my hot water and comes with MHI which is comparable to FIT. Is this a good thing to invest in, any views? mark |

MHI? Presumably you mean RHI (Renewable Heat Incentive). That has just gone into consultation (again) closes in Dec, announcement early 2013 should be in place summer 2013. The consultation document mentions 17.3p/kWhr for Solar Thermal for 7 years. Is this a good thing to invest in, any views? It's not a licence to steal money from everyone else like your FIT payments are. -- Cheers Dave. |

Is this a good thing to invest in, any views? mark You can just turn your immersion heater on when sufficient power is being generated by your PV system as you get paid for the electricity whether you use it or not. However, you can make a profit from the Renewable Heat Incentive which is to come in next year. The installation is to be subsidised and you get regular payments there after. Solar thermal panels are to be in the scheme. Dunno any numbers (£) yet. http://en.wikipedia.org/wiki/Renewable_Heat_Incentive So it may well be worth it from that point of view alone |

The RHI is a payment for heat produced only.

There might be money from ECO(*) to help with the capital costs. Not sure if the RHPP is still available. ... and you get regular payments there after. Solar thermal panels are to be in the scheme. Dunno any numbers (£) yet. Suggest you go and get the 116 page consultation document from the DECC website. The numbers aren't fixed yet but solar thermal looks to be getting 17.3p/kWhr over 7 years. How they are going to determine how much heat a solar thermal system produces isn't clear, at least not obviously clear but I got bored with 116 pages... They aren't keen on metering even for pellet boilers and heat pumps. My MCS certificate has a "Estimated Annual Generation (kWh)" field so I guess they'll just take that and multiply by the p/kWhr. If so my 30 tube solar thermal array will bring in a whopping £194.28/year. I reckon it's saved about £100 of oil at 60p/l. So over the 7 years that RHI is expected to run about £2000, about the installation cost so no great money making scheme like the FIT. (*) The 116 pages got the better of me again and as I already have a qualifying system wasn't that interested in getting help with the capital costs. -- Cheers Dave. |

If you sign up for Green Deal you don't have to pay up front, it is deducted from your future electricity bills. (Like an HP arrangement.) But you don't get the income as with the RHI, you can't have both. It's one or the other. |

No. The £300 for solar panel instalation is the RHPP (Renewable Heat Premium Payment) Phase 1 or Phase 2, I think Phase 2 is still active. Phase 1 closed at the end of March 2012. As I understand it RHPP will stop when RHI starts (or before if the pot of money runs out...). RHI (Renewable Heat Incentive) might (it is still only at ideas/consultation stage) pay qualifying systems a tarrif per kWhr produced (probably deemed to be produced for solar thermal) for seven years, maybe. Green Deal provides for the installation of insulation and other thermal improvements to homes. Paid for by a levy on the electricty bill. To qualify for RHI payments the home must have all the Green Deal (aka insulation) boxes ticked and have a valid MCS certificate. Currently there doesn't seem much, if anything, to help with the initial capital required to install a system that will qualify for RHI/RHPP. The Energy Company Obligation (ECO) (replaces CERT and CESP programmes) might be able to assist for the poorest or "difficult" buildings (ie solid walls etc). -- Cheers Dave. |

But they too are on the RHI thing. The details haven't been sorted out but the ground source heat pumps are definitely in the scheme and the air source ones might be last time I looked. "Bio-mass boilers" are also in the scheme. |

As you say for the RHI you have to fund it yourself. The Green Deal was for the poor people with no money. There is no "income" attached to that scheme. As long as the house is up to insulation standard you can go for other RHI schemes regardless if it was Green Deal or not. I have a sales rep coming round next week so I'll post anything I find out. |

How many kW does the "control " electronics take? Compared to the power that the compressor takes any control electronics will consume negligible power 100W at most done badly and perhaps only a few watts or less in standby. The unit is almost certainly useless but not for this reason. Pinching the name "Thermodynamics" like this should ring alarm bells as it is clearly done to confuse the public. Some fairly clever combined solar PV and water heating panels are on the market which use waste heat to warm up water. This has the bonus that it helps keep the PV array cooler and more efficient. The kit is obviously heavier as a result and I would worry about the additional complexity but at least it has genuine benefits. -- Regards, Martin Brown |

Scan (photograph) and post somewhere or is there a website? My curiosity has been tweaked. It could be air source heat pump but they have "boxes" with absorbers and fans rather a "panel". Here it is: http://www.prosolarpower.co.uk/free-hot-water mark Looks and smells like snake oil. CAVEAT EMPTOR! Something along the lines of an air source heat pump combined with a solar panel by the looks of it. Be interesting to see the graph of power output as a function of insolation and air temperature. How many kW does the "control " electronics take? Compared to the power that the compressor takes any control electronics will consume negligible power 100W at most done badly and perhaps only a few watts or less in standby. The unit is almost certainly useless but not for this reason. Pinching the name "Thermodynamics" like this should ring alarm bells as it is clearly done to confuse the public. Some fairly clever combined solar PV and water heating panels are on the market which use waste heat to warm up water. This has the bonus that it helps keep the PV array cooler and more efficient. The kit is obviously heavier as a result and I would worry about the additional complexity but at least it has genuine benefits. -- Regards, Martin Brown I think it's a air source heat pump but they boost the evaporator temperature with solar heat. Dunno how much benefit the solar bit would give. |
