Costs and performance characteristics for gas boilers and absorption chillers

CalBungMelb | Posted in Mechanicals on


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

    David Coote,
    I suggest that you contact commercial boiler manufacturers and commercial chiller manufacturers. You might also contact a contractor familiar with large commercial projects.

    This website focuses on residential construction. Most projects discussed on the GBA site need heating systems in the range of 4 kW to 10 kW -- not 500 kW or 1 MW.
