04.What to look for
Remote controls allow you to control the temperature settings and fan speeds, but only the Regency and Rinnai heaters include them as standard while the Heat & Glo has a wired remote and a wireless remote as an option.
Thermostats make it easier to set a desired temperature. Both Rinnai models, the Regency and the Heat & Glo come with a thermostat. 
Programmable timers will help with energy saving. All but the Cannon Fitzroy can be programmed to turn on and off during a 24-hour period.
Child locks were on the Rinnai heaters only and the Heat & Glo had it on the remote. We would like to see this feature on more of the products on test in future.
Electronic ignition All heaters had this feature, saving money with no pilot light running at all times. They all ignited satisfactorily.
A filter-clean warning feature would be useful, however only the Rinnai Aspiration had filters.
An LPG conversion kit allows you to operate the heater in areas without natural gas, but operating costs will be higher as a result. All models on test except the Cannon have this option.
