Hi @stevehsp Give us a rough idea of where you are and we might be able to suggest installers.

As for having solar panels, these are now less financially viable than having a storage battery in the house.
So both technology options would benefit from you starting a discussion topic here.

Heat-pumps will tend to demand more electricity input at times of the year when there is less sunshine.
So you could achieve lower running costs by opting for a Time of Use (ToU) tariff, and run the heat-pump off the battery.

There is no absolute answer for this.

Each homeowner will have different priorities, and the design/orientation of your roof matters too of course.

Save energy... recycle electrons!

Thanks for the welcome. For the solar PV we are including a battery. That will be done by an installer that has an assocaition with the forum and the process is underway. Tariffs are something I'm not properly up to speed on yet, but I don't have to think about that too much for a month or two.

We've had a number of quotes from ASHP installers which I'm currently working through. The differences are quite interesting ! I do have a specific question and will start a new topic as I don't think it's come up here so far (or if it has I can't find it)

@stevehsp

Can I suggest you read the introduction to ASHPs here as it will help understand the technology.

In terms of quote time choices

dont accept any proposal with a 4 port buffer, low loss header or plate heat exchanger. A 2 port volumiser is OK. 2 ports good, 4 ports bad!
do aim for the lowest practical flow temperature, which is dependent on the emitters (radiators) not the heat pump
sense check the sizing if you can and don't oversize too much
dont install 'smart' controls other than Homely (which is currently the only smart control specifically designed for heat pumps). For the avoidance of doubt this shouldn't be read as meaning that you need Homely (although if you pick one of the heat pumps with relatively crude controls it might be a good idea).
system design matters more than choice of heat pump but some heat pumps have better controls and are quieter than others

Feel free to post here any quotes for comment.

Hi all,

Based in NW Wales. Just had solar and a heat pump installed under the ECO4 scheme. Spent a lot of time lurking on the forum over the last few weeks to try and understand what's going on with this new system and found it to be a wealth of knowledge, so thank you all.
