Relight my fire? Investigating the true cost of

The ASHP (Option E) had 1 “New” includes the cost of purchasing the item and installa7on, while all op7ons include maintenance and replacement costs 2 The equivalent annual cost (EAC) is the discounted annual cost of owning, opera7ng, and maintaining the asset over a 15-year life 5 annual costs of £1,922-£1,796, 8%-9% higher than the gas boiler. [...] Drawing on the literature review, in this section we quantify the cost, environmental, social and health implications of woodburning for the households, and the wider environment and society, using a mix of quantitative indicators. [...] The damage costs for the key pollutants from wood burners with the bar indicating the central damage costs and the lower error the low damage costs estimates and the upper error bar the high damage cost estimates are shown in Figure 8. [...] In the central scenario, the two new wood burner options are the most expensive (Option 1C, NPC of - £26,316 and 2C, NPC of-£24,215), with the dual wood burner dominant system (Options 18 hEps://www.bankofengland.co.uk/monetary-policy/infla7on 19 hEps://academic.oup.com/heapol/ar7cle/35/1/107/5591528?login=false 20 The central and medium costs are the same for the gas boiler and ASHP scenarios 40. [...] Assuming we adopt the medium pollution assumption and the mid-range high efficiency stove, the health NPCs for the 15- year life of the system are £364 (1A) and £326 (2A) for the gas boiler only, £9,060 (1B) and £8,171 (2B) for the 80% wood burner options, £2,262 (1C) and £2,388 (2C) for the 20% wood burner option.
