My ASHP Journey in Bonnie Scotland.

Reed_Richards said: Oil boilers don't modulate.  They are either full on or off.  Gas boilers can typically modulate over a wide range of powers.

Technology has moved on. There are a handful of oil fired boilers on the market now that can modulate.

Daikin also launched one back in 2018, but I can find little about it since - https://www.daikin-ce.com/en_us/press-releases/2018/oil-considering-boiler-2018.html

But that is all an aside from the subject of heat pumps.

Yes, I know @FreeBear.  But "oil boilers don't modulate" is true as a generalisation even if not 100% true.

 R_R you should use the words "usually" or "generally" to avoid the pedants who feel they need to correct you

Just a wee update on my ASHP journey. 

Our electricity bills are predictably higher. It has peaked ( I hope) at £530 for January. 

To put this into context, I’m in Scotland and it’s cold. My brother, a builder is staying with us since mid December. He is converting the integral garage to a bedroom. For ease of transportation of materials the garage door still exists, despite internal wall changes etc etc. So the heating has been on excessively. At times he has also had additional fan heaters to dry paint  etc. I’m not complaining, I’m just justifying to myself why this winters bills are so high. Next year ( I hope) will be a contrast. 

Not only is brother incurring energy costs in relation to the work he is doing, also, obviously he is eating and showering! Our own shower has been changed to a mixer, benefitting from the ASHP. In brother’s bathroom however it is still an expensive 10Kw electric shower. Our new en suite will be a mixer shower - plumbing ready - ordered. When you are used to just two in the household the extra laundry, dishwashing, cooking etc is a massive increase. 

Although we did benefit from a 9 hour power cut when we relied on the generator. It was a great excuse to get that serviced and working again! 

Back to ASHP. My recent meter read showed that I used 54 KWh per day for January. That is massive, but I’m not unduly concerned. I know why it’s so high, and am fairly confident it will reduce next year. I’m glad that I pitched my DD higher than recommended although we are now running at a small debt.

Its amazing how much extra energy gets used when guests come to stay, even for a short time. We usually get descended upon by my daughters and their families over Xmas or the new year and our leccy consumption nigh on doubles for the time that they are here. Extra heating, cooking and ridiculous amounts of hot water.

I skim read this but I think you are with Octopus and at one point considering one of their smart tariffs.

Which did you end up on?

We are still on their SVT. 

We still have a Smart meter without comms hub, and therefore dumb. 

Octopus have said they need to change in, in response to my request to make it Smart. However there are no appointments available in my area! 

So I will have to wait until they do. I have ‘registered my interest’.

Hi, have now had my Ashp for 2 weeks. In the height of summer testing is tricky. Mainly using it for hot water, and that infrequently. I don’t have any monitoring devices apart from the Daikin MMI. I have the altherma 8kw. I find the ONECTA app practically useless. I have a mixergy cylinder,( water pressure too low for the Daikin cylinder). So trying to assess my COP. The MMI does provide figures for energy produced and energy consumed. But I have found the reporting is internally inconsistent. Total is different from sum of parts. Also I know exactly when I am using it and I know the load during the use period, so I know what it’s consuming. Those aren’t the figures the MMI is giving. So I’m looking to see if anyone has any experience to share in using the MMI and how they have found the accuracy of the reporting. Thanks

Finally we had a recent call from Octopus that they had an appointment to offer us to install a SMART meter. 

Unfortunately they were only able to give us 3 day’s notice as it was a cancellation. The date they offered was during a break we had booked to meet up with some friends in Aviemore. I was gutted to have to decline it. That was our only time away in recent months.

I have another date for SMART meter. It is next month, just a couple of weeks away. 

I am now busy studying the different tariffs available. I’m torn between Cosy and Agile. I have downloaded the Octopus Compare app and am studying how it functions but without any live data it is pretty meaningless. 

I have an idea of the complexities of Agile though. I think it is well named as you have to be pretty nippy to get the best from it I think. But we are both home all day so I think I could keep up with the constant changing of when to use the dishwasher etc. 

Once I have real data I will be able to see the daily averages etc. 

I’m wondering if people are subscribing to and deriving benefit from the ‘pro’ version?
