Just sold my coal bunker!!

allinthehead

Prior to August 2022 we had a Petrol car, diesel van, heated the house with Lpg and coal and used approx 4,500kwh of electricity.

Summer 2022 I started thinking about putting a couple of pv panels on my shed to charge a few power tools, but then I made the mistake of posting here for advice🤣.

Today we have a 10.75kwp diy array and 15kwh of batteries, we replaced the car and van with two ev's (new Tesla M3 and 2017 Hyundai Ioniq), I picked up a large storage heater on Donedeal for the upstairs heating

and just had a 5kw Mitsubishi air to air heat pump installed in the downstairs of the house and…

Just to add to the above, the plan is to keep the gas connection for the winter as a backup, I contacted Calor to check about the process of removing the meter and there's no charge. The stove will remain too as a further failsafe for the future and another air to air unit will be installed upstairs as soon as possible.

I hope the bunker was full.

Well done. Living the dream. I need to get going in that direction.

Na, kept the remains in the shed for emergencies.

Love it @allinthehead

I'm halfway there. 7.8kWp array, all electric house and zappi installed. Next years project will be to get rid of the ICE and replace with two EV's and a battery for the house (I might possibly DIY it). If I lose it altogether I may even hook up 4 more panels to a microinverter to generate power in the morning and evening when the south facing array production dips. The loss of generation at those times this spring and summer has killed me.

The dream is from autumn next year to have an annual net zero energy bill for the house and a vastly reduced bill for running the vehicles.

Nice size array you have, adding a 4 port microinverter is a great plan, they work very well indeed. The beauty of them is you could actually have all four panels facing in different directions and different angles if you wanted. It would supplement your array nicely.

My goal is to try to get through to next summer without burning anything and my motivation is purely to improve local air quality. I was lucky though in that I'm a trained electrician and I know the right people so my financial outlay has been minor apart from the Tesla of course.

I'm very interested in the A2A heat pump. Do you mind me asking what model and what sort of money it cost. They seem to be relatively inexpensive to buy but an arm and a leg to get installed! Were you able to avail of the SEAI grant?

Hi Paul, it's a 5kw Mitsubishi heavy industries. Srk-zs-wf is the model.

Unfortunately I can't give you a cost as I don't know. I didn't pay for it, I was owed a favour and I also did all the donkey work, coring of holes etc. I also did the electrical element.

The best quote I got when I was looking was 2,300 for a Hitachi unit.

To get the grant you must install a whole home solution and remove the existing boiler.

My install was completed in less than a day btw but as I said I pitched in. It was a very simple install too. Outside unit is directly behind the indoor unit.

Paul Kiernan

Thanks. It looks great. What connectors are needed from the inside to outside unit? Is it just 2 pipes for the refrigerant? Does the fitter have to be registered for Air-conditioning work (handling refrigerant, etc.!). And is that a condensate drain from the OS unit? Cheers, Paul

Yes must be an f-gas registered technician. 4 core 1.5sq nymj to indoor unit and two refrigerant pipes, sorry i'm not sure on the connectors. Condensate pipe running to drain also.

I bought a couple of these for a place we have up the road which only had electric night storage heaters

Cost £250.00 each to get installed (wasn't applying for any grant) and so far they have performed well, SCOP/COP of 4.5 have energy monitors on them and at full tilt on the 3.5Kw one it only draws between 700-900watts depending on outside air temperature, how long they last who knows, I stuck them on the wall inside and out, ran the power in and the guys did the rest.

Both online so can turn them on remotely to heat up the house before we arrive in the colder months.

Nice one, great price.

Hi all,

For those who have air to air systems installed- is it possible to cover the refrigerant lines which are encased in ducting with EWI insulation? Would probably have two units upstairs in a two story house and just panning ahead for a clean look installation.
