Comparing the main systems, vacuum tube and flat plate
The data shown below will vary from site to site, and between installations, the values are for guidance purposes only. The systems are listed in approximate order of apparent effectiveness against cost. This will of course vary between installations, other considerations are aesthetics, personal taste, scalability etc.
There are a growing number of systems, please email me with the comparable data along with a target price for yours if you want to be listed.
NB. The original comparison included a reference to LCBP, I have removed this as with any system installed now you should clarify eligibility for Renewable Heat Incentive.
