Thanks for that G and J I know exactly what you mean. I'll have to talk to my J 🤔

Thank Rick, indeed as you say my next step is to approach some installers. Do you have an opinion on Heat Geek for the air to water side?

Thank you all for your comments, I’m not a self build person really but got great project advice from this forum some years ago. I get that the first proposal is complex and expensive and I have an option B that Gemini has summarised below. I could keep my vented HWC but I’d like to remove the shower pump and cold water tank from the loft. I’d appreciate any further comment from the group Standalone Capital Project Cost Estimate By stripping away complex hybrid refrigeration-water networks and executing this clean, standalone Air-to-Air + Independent Slimline Direct Unvented Cylinder layout, your project total drops into an incredibly attractive budget bracket, remaining 100% eligible for the 0% VAT rate on the heat pump and cylinder elements: System 1 (Ground Floor A2A Multi-Split): 3 Midea Breezeless-E heads (Lounge, Sun Room, Kitchen): £1,900 – £2,300. System 2 (First Floor Loft Ducted + Playroom Head): Medium-static fan-coil + 4-zone motorized dampers + Playroom wall unit: £2,500 – £3,100. System 3 (Unvented Direct Cylinder Conversion): Supplying a 150L Slimline Direct tank, full gas boiler decommissioning, radiator removal, capping the gas mains, and removing the loft cold tank/shower pump: £2,200 – £2,900. System 4 (Bathroom Elements & Smart Towel Rails Fitted): £300 – £500. Boiler Resale Spare-Parts Credit (Private Cash Offset): -£80 to -£150. ESTIMATED NET CAPITAL OUT-OF-POCKET COST: £6,820 – £8,650 (No BUS Grant needed for this tier, keeping your capital outlay significantly lower than premium hybrid systems).

Sorry JohnMo below is more info (thanks to Google Gemini) but I need human input too! I am planning a 100% electrified, full gas-decommissioning project for a detached, traditional brick/block home in Nottingham (NG2). The house features filled cavity walls, solid concrete ground floors, and modern gas-filled, heat-reflective uPVC double glazing throughout. I am looking to specify the newly launched Samsung EHS Mono R290 (8kW) / Quint TDM Plus multi-hybrid platform integrated with the 200L ClimateHub floor-standing unit, utilizing the £7,500 BUS grant. The proposed design splits the home into a hybrid air-to-water and air-to-air network from that single outdoor compressor: Ground Floor Space Heating: We are retaining our existing Double-Column and Double-Panel radiators. However, these operate over an existing 8mm micro-bore copper pipe manifold infrastructure. To manage the high flow rate of the heat pump against the resistance of the 8mm pipes, the plan is to install a wall-mounted 50-litre close-coupled buffer vessel (e.g., Samsung MIM-B19N) inside the hot water cylinder cupboard to act as a hydraulic separator, powered by an external secondary variable-speed circulation pump (e.g., Grundfos UPS3). Ground Floor Cooling: We want to mount WindFree™ wall units downstairs in the Lounge, Sun Room, Playroom and Kitchen. First Floor Space Heating/Cooling: We are completely decommissioning and capping off all the existing low-surface-area single bedroom radiators. Instead, we want to run a medium-static ducted fan-coil matrix hidden in the loft, splitting into 4 bedrooms via insulated flex ducts, motorized electronic zoning dampers, and independent room thermostats. The playroom will get a standard wall head on the same side of the house. Grid Infrastructure & Tariff: The entire heating and hot water platform will be wired downstream of a Tesla Powerwall 3 and Gateway, running alongside our 6kWp solar array and the dynamic E.ON Next Optimise tariff.. My questions for the group: Has anyone got early field data or a hands-on review of the modulation floor and part-load efficiency of this new Samsung R290/TDM Quint chassis? Are there any hidden pitfalls when balancing a secondary pump curve across 8mm micro-bore manifolds downstream of a 50L low-loss buffer? How responsive is the SmartThings automation when attempting to interface with dynamic half-hourly grid tariff parameters alongside a home battery? Can anyone recommend an MCS-accredited, heat-pump expert installer covering the Nottingham/East Midlands area who has the hydronic and aerodynamic capabilities to handle a hybrid project like this? I am fully intending to commission an independent Heat Loss Hub / Heat Geek design package before signing a labour contract with any firm, but I would highly value any independent critique or advice on this kit combination before kicking off the formal engineering blueprint. Thanks in advance!

Does anyone have any knowledge about the above? I'm interested in installing a unit at my home to replace a gas boiler driven system and provide air conditioning. Thanks

Thanks Ferdinand, twice over ?

Hello buildhub. I'm helping my daughter and her husband with a project to renovate and extend a detached house in Sheffield. The house was built in 1956 and has remained in the ownership of the same family since then. As a family we are not particularly experienced in home improvement works and look forward to the advice that the members of buildhub will hopefully be able to offer
