No system should really be using this in this day and age, gas or Heat pump. This amendment could already move your SCOP up to 3. - Blending valves, bypasses and buffers have been unnecessarily left in and hinder efficiency by creating distortion.. (dilution of the flow temperature, meaning a higher than necessary flow temp is needed). This would likely push efficiency up to mid 3, looking at your ginormous radiators (even with solid brick). - The fact it’s a high-temperature unit does hinder the performance but considering that it was installed without rad upgrades previously MAY have been the right thing at the time. Ignoring the simple, easy quick fixes (1 day of labour), the main issue is the immense racket your poor neighbour has to put up with. Unfortunately, because the original installers didn’t lay a base for the unit (all units need a solid base), it has fallen and tilted back, which puts strain in the bearings they aren't designed for. This creates that grinding noise and will also mean the fan blades hit the ice. You have also had poor servicing, a decent service will make sure the unit is level, AT MINIMUM, let alone mention/service the bearings. Due to this you need a full stripdown and parts replacement of the outside unit. If we can get LG to help there, I have a Heat geek who is FGas registered to do that work for you and we can help with the rest too. If you somehow get a whole new unit which isn't a double compressor, you can expect mid 4 scops, even in a solid brick house, due to your huge rads. Swapping a unit out is actually much cheaper and easier than a fresh new installation. To give you an idea of what this could cost, to swap that unit out for a 12kW (need to complete a heat loss) Vaillant arotherm plus or VIessmann I would say would be around £7,000 as you already have the rest of the system in place. However, I'm open to helping out where possible. ========================================== #heatpump #homeimprovement #heating 🔗 Skill Builder Link Tree: https://linktr.ee/skillbuilder 📪 Newsletter: http://skill-builder.uk/signup https://www.tiktok.com/@skillbuilder https://www.facebook.com/skillbuilderchannel https://www.instagram.com/skill_builder https://twitter.com/skillbuilderuk 🛒 As an Amazon Associate, we earn from qualifying purchases 🎬 All videos: https://www.youtube.com/skillbuilderchannel/videos 💧 We Support Charity Water: https://www.charitywater.org ◾ Out of respect to our channel sponsors and the wide variety of people who watch our videos, we'll remove comments that do not follow expected standards of politeness and decency.
