Fitted Air conditioning
Discussion
Hoping to get A/C at our new house, Panasonic.
Had Mitsi at previous house and really missed it.
On a related note, I'm mulling over ASHP. Can these cool as effectively as A/C or not? We are buying a 20 year old 4 bed detached house where the current owner says it is a nice warm house. Appreciate a lot to consider but how suitable would this be for ASHP?

ASHP can't cool at all. No point getting ASHP and aircon, I'd just plump for the AC now at 0% VAT and don't worry about grants, will be the same level of efficiency without having the redo all your piprework and rip out what is probably a fully working gas boiler.
That one with unit on the front of the house, I didn't think that was allowed under the current building/planning regs?

We don't have the problem of neighbour's windows facing the side walls of our house.
Our house is set back maybe 4m or so from the neighbours house. So although the unit would be on the side of thier house, it would have been right next to and in front of the window on the front of our house.Also, the passageway (1.2m wide) between the houses is ours so it would've been overhanging onto our land, dripping water and meaning any servicing etc would have to be done from our land. Plus failure, falling off etc... definitely prefer it on the front of his house, even though its challenging on the eye....

May have been mentioned, but how much does one of these cost to run a day in £? Eg in the summer, like now, and you want it on in the evening to cool the room. Roughly
The Panasonic I looked at was 0.7kwh so I calculated it to be c. 30p an hour (based on electric being 40p p/kwh) Having said that, I may have just been looking at the indoor unit although I believe the there is only one power source. At least there was on our last install albeit it was 15 years ago plus.

You’d gladly pay double what it costs to run when you experience the delight of a cool room in 30c temperatures.CoolHands said:

For what you get it's worth every penny. We've got 2 under 2 both of which end up in our bed by the end of the night.
Fitting AC was one of the best things I ever bought, along with a super king bed.

'Careful with terminology here. A split "Air Conditioning" unit, is for all intents a purposes, an Air Source Heat Pump, as they can nearly all provide both heating and cooling. I think I know what you mean though, you are referring to an outdoor unit which works via heat pump boiler (integral or otherwise) to provide LTHW heat only.
I would agree with what you have said though, if you are considering adding the provision of cooling to your property and at the same time looking for future proofing the heating of your home, you'd not go far wrong to install a series of split units or indeed a multi split or VRV system, which will provide both heating and cooling (via blown air), with no need to worry about having to find space for a heat pump boiler, uprating radiator size or adjusting pipe work.
Coefficient of Performance (aka Efficiency) of a well designed and good quality split system operating in the winter in the 0-15 degree outdoor ambient range (which is pretty typical for most of the UK) would be around 2 (200%) to 4.5 (450%). Below -5 however, and most units will struggle in reality and you'd be grateful for having kept your gas boiler and radiators.

So last week was the first time I had used ours in anger, had it on most of the day, about 1kw/h for the first hour and then it dropped to 4-500w/h keeping the temperatures in check and this was for a 4 bedroom ceiling ducted system. Getting solar next week, so summer costs for me should be 0.MattyD803 said:

Indeed, sorry yeah, was just going by the common terminologies used, as above I found my AC to be using about the equivalent amount in £ of electricity as gas last year when it was 5-10c, but when it goes below this the gas is more efficient £ for £. Hoping to offset this with Solar and Battery storage to minimise gas usage, along with increased insulation added this year to walls and ceilings.I would agree with what you have said though, if you are considering adding the provision of cooling to your property and at the same time looking for future proofing the heating of your home, you'd not go far wrong to install a series of split units or indeed a multi split or VRV system, which will provide both heating and cooling (via blown air), with no need to worry about having to find space for a heat pump boiler, uprating radiator size or adjusting pipe work.

Our Mitsubishi split unit is about 1kW cooling a south facing room to 20c, so 3-4 hours late afternoon will be about 4kWh or 60pessayer said:

As everyone else echos, the cost is so insignificant it’s not worth considering. I have a 27k BTU unit which does 3 bedrooms. With all three units on full pelt and turbo mode, it consumes a maximum of 1kw initially, once we’re nearer required temps it throttles right down to around 500-600w.
I would estimate on a really hot day if you run it for a few hours, you would use a £1 leccy give it take. Now if I offered you a great nights sleep in a cool comfortable room for a £1 , you’d snap my arm off

Only problem I can see is where we locate the outdoor unit but we have a bit of time to consider.
In my head is expect the unit and install to be c. £10k so down to £5k with the new grant?
