Share your heat pump experience

Hi yes happy to do written ? 

Fine, just a note that I am away from 1st September until 14th September. I have a Grant Heat Pump and it was installed 5 years ago.

Very happy to “talk Heat Pumps” following 12 years experience with a Ground Source heat pump.  Also very aware of improvement in Air Source HP design from the early days when icing-up was a serious problem.

Yes happy to help...

I’d be happy to help.  We have a had a Mitsubishi EcoDan ASHP since March 2021.  It copes really well with our 30 year old home even through the really cold snap we had last winter.

I have been lucky enough to get off fossil fuels completely when I got an EV in 2020, then had the gas disconnected in 2021 and closed the loop by getting some solar and storage fitted earlier this year.  The electric bills were pretty expensive looking last winter but when you take into account its ALL my mileage and heating its not too bad at all (I used to fill up my tank once per week) .  I’m looking forward to the storage allowing me to offset those expensive peak rates with cheap night EV tariffs on the days the sun doesn’t shine, this winter as all these investments start to pay for themselves.

Just moved from SSE to OVO.
Hoping OVO can champion new opportunities of smart management of customers HP energy demands, although perhaps initially offer attractive electricity tariffs which suit these demands.
As a retired engineer - interested in encouraging domestic appliance designers to embrace totally new frameworks for electrical energy distribution in homes. - more to follow!
 

Yeah I am happy to be used as a case study 

Very happy to be part of this too. Either Film or written about our experiences. 

I am almost 3 years into my install, and trailing different ways each year to see what works best for winters. 

Not sure my experience is going to be much help to others, except that I have shown it probably costs less than you think to get started.

A couple of years ago I added a small ground floor extension to the living room of my 3 bed semi and one wall was almost 100% glass and south facing so I knew the heat gain was going to be too much, and Air Con was going to be a must have. I have used portable units in the past but these are expensive to run, noisy and inefficient. and take up room

Nearly all AC units these days are actually air to air heat pumps so the unit I had installed could do heating and cooling. I still had my traditional gas boiler/water heating extended and treated the heating function of the AC unit as a bonus.

Its proved to be a great success, so much so that I had another unit installed in our bedroom.

The downstairs unit consumes 1KW of electricity, when it needs to and provides about 5KW of heating and cooling capacity. When I bought it there was still VAT on such items and it cost about £2500 and half a day to install. 

The upstairs unit is about 2.5KW and cost about £1300 and again took less than half a day to install.

Both units are on outside walls, so getting rid of condensate is easy and the outside units are on my garage roof. 

The downstairs unit is able to heat or cool the area in a few minutes, however, it does not heat the fabric of the house in this time so its best for a quick warm up or cool down.

Changing to a full heat exchange system for hot water and radiators is going to be inconvenient and costly, but for a small area, especially if its open plan, what I have plus a water heater is worth considering.

I realise looking at other replies that I may not have given enough information.

I have 24 solar panels of 375W giving theoretically 9Kw, 

They go through a7.5 KTLM G2 invertor

That feeds the house and 2 GivEnergy batteries of 8.5 and 9,3 Kw. 

The car charger is a Indra Pro.

These above all fitted in the Autumn of 2022.

The house was built in 2018 with underfloor heating on ground floor and wet radiators 1st floor. All heated by an Air to water heat pump a Grant Aerona3 HPID 16 this has now been running 5years and 6 months.

Air conditioning has been fitted on the ground floor and master bedroom all by Daikin.

They are extremely cheap to run and very necessary with a modern build and insulated house with double and triple glazing.

Our EPC is 95 A+

No gas is available in our area so we are totally reliant on electricity,

We had to fit a sealed wood burning stove under local building regs. We lit it a couple of times but it drives us out of the rooms!

Hope this helps to understand our system , the house is 3,300 sq, ft.
