英国采购需求：地热/水对水热泵

I'd like to request your best pricing for your R290 ground source heat pumps. Our company installs approximately 2000 units annually in the UK and is seeking a reliable OEM partner for white labeling. It's crucial for us to understand your pricing structure and terms, especially if we consider a long-term relationship to scale our operations. Could you also confirm whether your heat pumps have CE/UKCA certifications? Additionally, it's important to know if your products are listed on the MCS database. If they aren't, we are open to discussing potential accreditation, contingent upon pricing and exclusivity options within the UK market. Looking forward to your prompt response!
