People often ask, “How do diesel cooktops compare with gas, and how long does it take to boil the jug?” Well, it depends on a few factors, but to keep it short the answer is it does take a little longer.
We have done some heating tests on our Wallas cooktops. We used an XC Duo, but the following applies to all Wallas diesel cooktops. Lets look at a few things. Gas is instantaneous heat, Wallas diesel cooktops require time to get started. After doing some tests we found that with 2.0L of water in a jug at 16.5 °C using gas it takes 13 minutes while using a diesel cooktop it takes 18 minutes to boil.
The drawback with diesel cooktops is that it takes 12 minutes for the cooktop to reach maximum temperature (500 °C ) making the total time to “boil the jug” 30 minutes from stove switch on. It does take some planning when using diesel; when you get up in the morning to “boil the jug” and do what nature needs you to do, just turn the cooktop on and when you come back it is up to temperature ready to put the jug on. Of course, if the stove is already on from boiling the jug, cooking brekkie right after will save that startup time.
When you are on holidays, does 10-15 minutes extra make a difference when compared to the enormous advantages of Wallas diesel cooktops over gas (safer, no condensation, cheaper to run, easier to fill, no compliance issues)? You, the customer, need to work that out for yourselves, but here at Dieselheat, we think the benefits usually speak for themselves.
