System renewal

You have a few good options, and the best one depends on your budget, the insulation levels of the cottage, and whether you want to future-proof the property. Option 1 – Air Source Heat Pump (Recommended) This is generally the best long-term replacement for an oil boiler. * Replace the oil boiler with an air source heat pump. * Reuse your existing hot water cylinder if it is heat pump compatible (many newer cylinders are, but it would need checking). * Reuse most of your existing heating pipework. * Existing radiators may be suitable, although some may need upgrading to larger sizes as heat pumps operate at lower flow temperatures. * Install wall-mounted air conditioning units in the rooms you want to cool. These provide cooling in summer and can also provide very efficient heating in spring and autumn. Pros: * Lowest running costs when designed correctly. * Eligible for grants (such as the Boiler Upgrade Scheme, subject to availability and eligibility). * Future-proof and environmentally friendly. * Can combine heating, hot water and cooling. Cons: * Higher initial installation cost. * May require some radiator upgrades. Option 2 – Electric Boiler Replace the oil boiler with an electric boiler. * Existing pipework and radiators can usually remain. * Existing hot water cylinder can often be retained. * Separate air conditioning units would still be required for cooling. Pros: * Lower installation cost. * Minimal changes to the existing heating system. * Quiet and compact. Cons: * Electricity is significantly more expensive than oil or a heat pump, so running costs can be high. * Not ideal for larger properties. Option 3 – Air-to-Air Heat Pump (Split Air Conditioning) Install multiple air conditioning units that both heat and cool the property. * Excellent for cooling in summer. * Very efficient heating. * Existing radiator system could remain solely for hot water or as a backup. Pros: * Excellent cooling. * Fast response. * Very efficient heating. Cons: * Doesn’t heat water, so you’d still need a separate hot water solution. * Heat is delivered via warm air rather than radiators. Option 4 – Hybrid Approach Many people renovating cottages choose a combination: * Air source heat pump for heating and hot water. * Existing radiator system retained where practical. * Air conditioning units installed in bedrooms and living areas for summer cooling and additional winter heating. This provides the most comfortable year-round solution. Before deciding I’d recommend having a full heat loss calculation carried out. This will determine: * Whether your existing radiators are large enough. * Whether your hot water cylinder is compatible. * The correct size of heat pump. * Expected running costs. Without this, it’s impossible to recommend the correct equipment with confidence. From what you’ve described - a cottage currently heated by oil with a relatively new cylinder and a desire for summer cooling - an air source heat pump combined with separate air conditioning units in the rooms you want to cool would typically be the most practical and future-proof solution while allowing much of the existing heating infrastructure to be reused.

Air source heating currently a grant of £9500 is available. Cooling will need separate units for each area requiring cooling.
