Air Source Heat Pump
Discussion
Hi folks we moved house in March last year and are getting slowly there so next job being the heating.
Currently we have oil fired heating which has a non condensing boiler which coupled with the general crustyness of the metal fitting on the external tank means investment is needed. However due to the trend of phasing out fossil fired systems we have been looking into heat pumps as our old property had one.
We have had the survey done by energy savings trust scotland and are able to get the interest free loan via MCS so are looking at installers etc just now.
My question is most have quoted LG and Samsung systems which I am not that familiar with as our last one was a Daikin. Are there any brands we should avoid etc I have heard Nibe, Grant and Mitsubishi mentioned as good, we are also struggling to find much in the way of local installers etc here in Aberdeenshire.
I was considering maybe leaving the oil in perhaps to act as a boost if needed but this could scupper MCS/RHI I guess. Regardless we will need a couple of extra radiators in also due to some poor layout decisions by previous owners. I know insulation is key to any ashp install due to lower leaving water temps so will look at that all first.
Sorry for long post,any advice much appreciated as to brands to avoid etc and installs. Thanks

Thanks for the replies although no need for the tone in the first one I am just after some advice.
The property is a 3 bedroom detached brick property built in 1993 with approximately 180m2 floor space split over 2 floors. The windows I believe were all replaced 5 years ago to new double glazed units and there is approx 120mm insulation in loft which will need upgraded. There is also a supplementary log burner in the kitchen. My initial thoughts is to maybe just upgrade the tank and boiler but this is a finite solution perhaps.

Cheers for the replies confirmed my initial thoughts as many have said it's better suited to new builds which have good insulation. As the lwt is a good bit lower than the oil fired system we have. Dont want to start oversizings rads etc so will look at getting a condensing boiler. Thanks folks
Jambo85 drop me a PM please?
I would agree with the comments on the performance of system at low temps too as we found especially when it was cold for several days running the daikin would struggle a bit. In regards to the defrost cycle if I am correct it also needs sufficient volume to ensure it can do this for the rad it it linked to. I was more curious about manufactures than anything as only had experience with Daikin.
