Nibe Fighter 360p ashp costing me loads to run

If it is the right size air pump and not too small they do and will work well,

Couldn't agree with you more sir! If you read one of the latest press releases from the DECC, Chris Hulme talks about the country is entering a "transisional" period by domestic heating moving from gas to electricity. So it looks like heat pumps are here to stay. Companies need to start getting their act together and whats more starting to work together, or its all going to come toppling down.

I am not sure off the top of my head but what i do know is that someting has to go in like a ashp or combi with solar water etc, i do not know why they did not install solar with the nibe as the nibe can be docked with a solar and or gas also be docked with a gas combi but they should have done their research first.

Was yours a "Section 106" house do you know? If so Merlin would of had no say in the design or what goes in it.



See mine really isn't that much smaller and yet your bills seem to be astronomically bigger! I just don't get it. On day like today it shouldn't really be using the emersion as its warm enough to heat the water from the air.

Just a quick update from 00.00am today untill 12.52pm total 12hr 51 min the nibe has used £2.85p outdoor temp is 9.5c now at 12.52pm

Thats "Code 3" for sustainable housing. "Section 106" is apart of the Planning Act. When a developer applies for planning permission, they will have certain requirements they need to meet in "Section 106". Could be to help fund a new school, etc as it has a knock on effect.

Also as part of "Section 106", they will stipulate that some of their houses need to be allocated for social housing. Whether renting or shared ownership. I think the normal figure is 10%. The housing association then come along and buy them up (at a discounted rate and flog them onto you at market value). But the point is they have no say in the design. The house builder only builds them to meet with planning requirements.

That rings a bell code 3 housing, Where we live some are rented and 2 houses are shared ownership but those 2 houses are alot smaller than ours,

So really it is Greenhill Constructions fault for installing a unit that can not meet the house needs, The only thing they can do then is get rid of the nibe exhaust air pump and install a better external mechanical air pump according to nu-heat a external air pump can heat the water to 35 degrees Centigrade and 45 degrees Centigrade the highest i have seen out nibe heat the water is aound 28c with out the immersion kicking in when it is mild outside this goes to prove the nibe can not cope but Greenhill are having non of it so i am stuck really,

Just a question. What is the Kw of the pump output, to save trawling back through the posts. If your house is circa 100 sq mtrs, you should have one of between 7 - 9 Kw on normal insulation levels.

Well with just the compressor and fan running it is using 0.81kw and them when the immersion kicks in it jumps up to 7.20kw

8KW on the immersion and 2KW on the compressor.

Thanks i was just about to post that:) I have been told that a 2kw compressor is too small for the house that is why i have been told i need a external air to water 4kw or bigger unit,

Sorry, I mean the rated Kw output against the input Kw. e.g 1.5Kw in/ 4.0 Kw out.
I have a 11.00Kw output gshp with an input of 2.2Kw. Ignore the immersion or the moment, as if the pump is correctly sized then that should not be kicking in as much.
