Greenhouse Heating - Black Forest style!

Many thanks for your recent enquiry regarding the benefits of the new Black Forest Catalytic Heaters we stock.   

The Black Forest Catalytic heaters are superior to their gas and propane fired counterparts in theory, but we can’t comment on the results of using one of these heaters as we simply haven’t had the time to test and compare them! A true comparison would be very difficult anyway as you’d need to almost replicate the conditions – same plants, same weather, same feeding regime and same greenhouse – to obtain worthwhile data so we are really guided by the technical specifications, which are impressive.  

The main advantage of using the catalytic heaters over gas or propane is the efficiency  and cost saving. The catalytic burner has a thermal efficiency of over 99% and the warm air it produces is also enriched with CO2, which of course is ideal for growing plants. Normal gas, propane and paraffin heaters often do not attain complete combustion which can lead to a build-up of carbon monoxide, do not pump CO2 into your greenhouse and are generally less efficient to run.  

You’ll find that the gas consumption of the 2kw catalytic heater when operating on full burner (0.156kg/hr) compares favourably to similar sized models; and this size of heater will comfortably heat your 2.4m x 2.4m greenhouse so the extra financial outlay on a 3.5kw version will take a long time to recoup! We would advise lining your greenhouse with bubble insulation as this form of ‘double glazing’ can further reduce your heating costs by up to 30%.  

Finally, I can confirm that the catalytic heaters are supplied complete with a regulator and 1.4m of tubing. The discrepancy between the catalogue and website arose as originally, the heaters were not going to be supplied with these components but now they are. Unfortunately, the catalogue had already gone to print but amending the website copy was a simple task – so the website is correct!
