Hi,

I’m doing some research comparing various technology solutions for heating and cooling.

What I’m lacking is cost curves and performance characteristics for gas boilers and absorption chillers. I would like to have the costs and efficiencies for condensing and non-condensing gas boilers at, say, 50kW, 100kW, 200kW, 500kW and 1MW. And costs and efficiencies for single-effect absorption chillers at, say, a couple of hundred kW cooling capacity upwards.

I’ve found some data on gas boiler costs in some UK references but only for a small number of sizes.

If anyone could point me at more complete references I would be most grateful

Thanks

David
