MRK-100K vs MRK-100: Which Mestic Gas Heater Should You Buy?
MRK-100K vs MRK-100: Which Mestic Gas Heater Should You Buy? is a decision that many caravan and campervan owners face when planning for cooler weather. Both gas and electric heating have distinct advantages, and the right choice depends on where you camp, your power setup, and your comfort priorities. Here is a clear comparison.
Gas Heating: The MRK-100 and MRK-100K
The Mestic MRK-100 (£109.99) and MRK-100K (£101.99) are infrared gas heaters operating on 30mbar propane or butane. They use piezoelectric ignition, meaning no batteries or electrical connection is needed to start them. Infrared radiant heat warms objects and people directly rather than heating the air, which makes them effective in semi-open spaces like caravan awnings and porch areas.
The MRK-100 comes fully assembled and ready to use. The MRK-100K is a self-assembly version that saves £8, making it popular with hands-on buyers who do not mind putting it together. Both produce the same heat output and use the same 30mbar gas connection standard found across UK caravan gas systems.
Electric Heating: The MKK-230
The Mestic MKK-230 (£34.99) is a compact 230V ceramic fan heater that requires a campsite electric hook-up. It distributes heat evenly through a fan, which warms the air throughout an enclosed space. This makes it suitable for heating the interior of a caravan or campervan where you want consistent ambient temperature.
The MKK-230 has no open flame, produces no combustion gases, and requires no ventilation beyond what you would normally have. This makes it the simpler and arguably safer option for heating enclosed living spaces, especially overnight. The main limitation is that it only works where 230V mains power is available.
Which Should You Choose?
Choose the MRK-100 or MRK-100K if you need heating without mains power: wild camping, awning heating, or as backup when hook-up is unavailable. Gas heaters are ideal for awnings and outdoor living areas where ventilation is naturally good and you want quick, directional warmth.
Choose the MKK-230 if you mostly camp on sites with electric hook-up and want safe, unattended heating inside your living space. At £34.99 it is the most affordable heater in the range and the running cost on campsite electricity is included in your pitch fee.
Many experienced tourers carry both: the MKK-230 for inside heating on hook-up nights and the MRK-100 for the awning on every night. This combination covers all scenarios for less than £150 total.
Final Thoughts
There is no single best answer. Your camping style determines the right choice, and owning both gas and electric options gives you maximum flexibility.
