ASHP installed together with existing heating system
Hi all.
I currently have the setup as attached. Because I'm really fed up with wood (as it produces a lot of dirt, it's not possible to preheat and I need to burn wood every day for DHW) I'd like to install an ASHP, so I asked for some quotations and all the calculations point to 9kW. The goal is to install both systems together, so that I'm able to use the wood burner sporadically if I wish.
I'd like to consider buying the equipment myself, then get a certified installer to...
I need some further advice on 2 issues, both related to the installation.
- insulation of the pipes and connections. Although the installer was very careful in distributing the pipes on the wall to reduce "dead space", I'm a bit concerned about insulation.
All pipes have an external insulation sleeve, which is the same on the inside and outside. But all connection parts (especially 90º metallic - brass? - curves) are not insulated at all. Outside, there are 2 of these curves. In
