Gas Boiler

The gas boiler represent a device that burns gas to produce heat for space heating and domestic hot water. It is situated in individual buildings and therefore contributes a constant share to the overal heat production. It has a constant efficiency and constant carbon emissions per kWh of energy converted.

Attribute	Unit	Data type	Description
deployment	–	bool	If set to ‘true’, the technology will be considered in the energy system model (this does not necessarily mean it will be used). Only relevant for optimisation.
kW_th_max	kW	float	Maximum thermal capacity (i.e. heat output).
hv_gas_MJpkg	MJ/kg	float	Lower heating value of gas.
eta	–	float	Conversion efficiency from fuel to heat.
gas_price_CHFpkWh	CHF/kWh	float	Gas price (annual fixed value).
co2_intensity	kg CO2/kWh	float	Carbon-dioxide intensity of technology output (annual average value).
lifetime	years	int	Expected lifetime of technology before replacement is required.
interest_rate	–	float	Interest rate for computing levelised costs (if required).
replacement_factor	–	float	Used for scenario ‘fossil_heater_retrofit’. Fraction of heating capacity to be replaced by heat pumps.
capex	CHF/kWp	float	CAPEX cost of technology per unit of capacity.
capex_one_to_one_replacement	CHF/kWp	float	CAPEX cost of technology per unit of capacity (when device has reached the end of life)
maintenance_cost	CHF/kWp/year	float	OPEX cost of technology.
