Smart controls run the heat pump as the primary heat source when it's efficient to do so, and call the boiler in for cold snaps, hot water peaks or when electricity is expensive. This avoids the biggest barrier to heat pump adoption: properties that need substantial radiator and insulation upgrades to run entirely on a heat pump can usually run a hybrid without those upgrades, because the boiler handles the worst-case demand. Real-world result: typically 60-80% of annual heating supplied by the heat pump (CO₂ savings of around 50-60%), with the gas boiler handling peaks and hot water. Total cost is significantly less than a full heat pump retrofit, with most of the carbon benefit. ## Real Work Examples ## When a Hybrid Beats a Full Heat Pump or Just-a-Boiler Hybrid systems are a pragmatic middle ground for many UK homes. They make sense particularly for older properties where full heat pump retrofit would need significant insulation and radiator upgrades — and where the cost of those upgrades makes the full project unaffordable today. Older properties (pre-1990s) often have heat losses too high for sensible heat pump-only operation - Existing radiators may not be large enough for the low flow temperatures heat pumps prefer - Hot water demand peaks (multiple showers) can be hard for heat pumps to meet without large cylinders - Hybrid avoids these constraints by letting the boiler handle peaks and hot water - Smart controls run the heat pump when cheap electricity is available; boiler when gas is cheaper ## Our Process 1 ### Free Initial Visit Site assessment — likely heat pump position, electrical capacity, existing boiler condition, radiator audit. 2 ### Heat Loss & Design MCS heat loss calculation. System design selects appropriate heat pump size for hybrid operation (typically smaller than full retrofit). 3 ### Quote Quote covers heat pump, controls, integration with new or existing boiler, hot water cylinder if required, and electrical works. 4 ### Installation Typically 2-4 days: outdoor unit, indoor controls, integration into existing wet system, smart controls. 5 ### Commission & Handover Smart switching logic configured (typically by outside temperature or energy price), system balanced, full handover. ## Why Choose Conroy ### Carbon Cut Without Full Retrofit Typical 50-60% reduction in heating CO₂ vs gas-only — without the cost of full insulation/radiator upgrades. ### Gas Boiler Handles Peaks Cold snaps and multiple hot water demands handled by the boiler — no compromises on comfort. ### Smart Switching Controls optimise heat source based on outside temperature, hot water demand and electricity price. ### Lower Upfront Cost Significantly cheaper than full heat pump retrofit — smaller pump, fewer radiator upgrades, existing boiler reused. ### Future-Proof Provides a path to full renewables later — heat pump capacity can be increased and boiler removed once insulation upgrades are done. ### MCS-Quality Design Heat loss surveyed properly, system designed to deliver real-world efficiency — not just specified to a budget. ## Technical Detail ### Heat Pump Sizing Hybrid heat pumps are typically sized to cover the 'middle 80%' of annual heat demand — enough to run all year except the coldest days, while the boiler handles peaks. ### Smart Switching Logic Controls choose heat source based on outside temperature (above 0-5°C = heat pump, below = boiler) and instantaneous energy prices on smart tariffs. Some systems also factor in hot water demand. ### Existing Boiler Integration Most modern combi, system and heat-only boilers can integrate with hybrid heat pump controls. Older or unbranded boilers may need replacement; we confirm during survey. ### Hot Water Strategy Most hybrid systems use the gas boiler for hot water (cheaper and faster than heat pump heating of large cylinders), with the heat pump pre-heating or supplementing where efficient. ### Path to Full Renewables A hybrid is a stepping stone for many households — install hybrid now, then upgrade insulation and radiators progressively, then remove the boiler entirely once the heat pump can handle 100% of load. ## Frequently Asked Questions ### svg]:rotate-180 text-left font-semibold text-foreground hover:text-accent hover:no-underline py-4" data-radix-collection-item="">How does the system know when to use which? ### svg]:rotate-180 text-left font-semibold text-foreground hover:text-accent hover:no-underline py-4" data-radix-collection-item="">Will I save money vs gas-only? ### svg]:rotate-180 text-left font-semibold text-foreground hover:text-accent hover:no-underline py-4" data-radix-collection-item="">Is the BUS grant available for hybrids? ### svg]:rotate-180 text-left font-semibold text-foreground hover:text-accent hover:no-underline py-4" data-radix-collection-item="">Can I add a heat pump to my existing boiler? ### svg]:rotate-180 text-left font-semibold text-foreground hover:text-accent hover:no-underline py-4" data-radix-collection-item="">How long does installation take?
