HeatGeek Quote Check

Right, had my a heatgeek installer come out and do the survey and have come back with my results.

House Details:

160 Square Meters. Detached, (some outside walls are touching the garage)

Double Glazed Wooden Windows, 275mm Brick-Cavity(Rockwool slab insulation)-High Performance Brick.

Solid Floor (no insulation)

No loft rooms or ceiling windows, loft has 300m insulation.

All radiators are K1's and not overly large aside from one K2 in the lounge, I have the full specs, but there's 14 of them and if i put it down that will be far too much. (before the install goes in I am replacing with 4 column radiators all round - the wife wants aesthetically pleasing rads - but these are not reflected in the survey)

No hot water tank, currently on a 30kw 10 year old worcester bosch combi unit.

I can't really compare gas usage as during the winter I would put the heating on for an hour in the morning and an hour at night, the house was regularly around 14-16 degrees. I'm expecting to run the heatpump all the time in weather compensation at around 18-20 so it will be hard to measure financial differences as my house will be far more comfortable.

I have a 19 Panel (8.75Kwp) south facing solar array, with 15.36kWh of battery installed as well.

Heatloss came out to 5.8Kw

Now for the Quote

£5650 including BUS for an Aerotherm Pro 7kW. Efficiency Guaranteed: 450%

or

£5700 for a 5kW Aerotherm Plus. Efficiency guaranteed: 425%

Both these estimates come with a 300l fuel tank, there's only 2 of us now, but the family is expected to grow and we regularly have guests, so i would rather have too much than too little, especially as the cost difference is only 100 quid.

Chatting to my HeatGeek who was excellent he explained that the Pro can modulate lower down than the Plus and hence why I'm getting a higher efficiency rating with it. I'm leaning towards the pro, even with the warranty difference tbh. Alongside the fact it looks far better. The 5kW on the plus also slightly worries me as to whether it will be able to reach the heatloss in the darkest depths of winter.

I had a quote from EDF at £7500, AIRA at £9500 both were fixed costs, before survey. Octopus was cheaper, but I've not seen any of their systems get much above a 350% SCOP and over time that will cost me a lot.

I am a bit curious as to how they can get such a high SCOP with no rad changes. My heatpunk model doesn't agree, but then again I'm no expert.

I think I've been thorough with this, but can anyone think of anything I've missed?

Octopus Intelligent Flux - Add Device Failure - HanchuESS

Hi all, finally got onto Octopus Intelligent Flux yesterday night. I've gone to add my inverter to my Octopus App however when I do so the portal it takes me to to login with my HanchuESS account just says acount/password mismatch whenever I put my correct details in.

Here are the steps I've taken so far:

  1. Changed passwords on both Octopus and HanchuESS. No joy.

  2. Deleted and reinstalled both apps.

  3. Checked I have full access to the HanchuESS app as an owner. (I do).

  4. Rang Octopus, they have just said they can't help as there is no error on their end.

I've reached out to HanchuESS but not had anything back yet. I don't think it's their end, i just wish I didn't have to do this via my app. It's annoying because it's clear that the add device page uses a webapp not the octopus app itself.

Has anyone had a similar problem or managed to get it resolved?

Is there any hint when these tariffs will come back online?

I'm using 5Kwh a day and exporting 35 atm and am absolutely begging to be let onto IOF, but still not seen anything since they changed it following Trumps strategic 4d chess masterpiece.

Seen some people have been able to get onto it regardless by phoning them up and being a pest, anyone got any advice on how to do this?
