Good Morning All,

Just to add to issues being experienced with the Solar ET, the Growatt keeps giving BMS error messages and the Immersun now won't start up because the fan appears to have gone tits up. I'm getting an Error 13 - fan fault.

Isn't technology wonderful?

Current priority is getting my Turner engined Land-Rover ready for Glamis this weekend.

Regards

Good Evening All,

I'm sat here watching 'Have I got news for you' with 445W (655W total demand) of power being provided by the Growatt and the house heating provided by the the heat energy in the EHS, it could be worse.

Regards

Good Morning All,

Carried out the annual filter and UV lamp replacement yesterday so that must be two years since we installed the pressurised water system to go with the heat pump. It has been very reliable to date with only one leak when the top on the UV steriliser worked itself loose.

£64.20 for the UV lamp and filter element.

Regards

Richard

Good Morning All,

We're currently enjoying 'blazing' sunshine although it didn't get above the horizon until 10 o'clock....... I really do need to re-locate this property to the other side of the valley!!!!

That's the heat pump just cut out so all FIT registered Solar PV is now heating the EHS, except for the 200W Immersun export trigger for the Growatt and the Solar ET is also contributing to the EHS.

As the heat pump 'runs' 24/7 yesterday it went over to circulating the CH through the EHS for about 5hrs - theoretically 'free' heat.

I continue my love/ hate relationship with the Growatt. Yesterday was somewhat similar to today with sunshine and some cloud, the Growatt was behaving itself and gave back 1.1kW after sundown in addition to the 11.1kW we generated according to the Immersun.

Regards

Good Afternoon All,

Prompted by a recent posting on this forum re installing a Baxi Ecogen Iíve sat down and re-worked figures iro equipment installed here at Courtiestown.

Going back two years we were spending £1875 a year on electricity and £1575 a year on gas making a total energy spend of £3450. Quite frightening really.

We are currently spending £1230 a year on electricity so a saving of £2220 on where we were in overall energy expenditure. It is very difficult to break this down as there are a number of factors which have contributed to this:-

1.   Driving down some wasteful users of electricity and practices
2.   The addition of 1.675kW of solar panels + the Growatt
3.   On and off contribution of Solar ET
4.   Aggressive monitoring of electricity supply deals

We currently get £4135 a year in RHI payments against which we pay out £1344 in EST loans. In fairness the loans run to 10 years against the RHI only being paid for 7 years but right now we benefit by £2791 per year.

In total we are benefiting to the tune of £2220 + £2791 = £5011 a year on where we were. OK so the benefit will reduce as the electricity prices increase over the 7 years, if we call it say 10% then at the end of 7 years we would be circa £32,000 better off than if we had maintained the status quo.

Against this we will owe £4032 in EST loans over 3 years when the RHI stops.

On a less avaricious note one thing I've noticed appears to be happening since the install of the Growatt. In conditions where the sun comes and goes then the Immersun is obviously doing its thing in diverting energy to the EHS BUT I am seeing frequent 'glitches' in the Immersun diversion which I believe is likely caused by the Growatt charging process cutting in and out thus affecting the 'export' as seen by the Immersun CT.

Regards
