FREQUENTLY ASKED QUESTIONS - GAS DUCTED HEATING

Q Can I turn off outlets if I am not using them?

A Yes, it can be more efficient if you close off outlets in rooms that are not used. This is called "zoning" - and it is possible to have it done electronically i.e. You can turn off a formal living area by pressing a button on the wall controller. However, depending on the size of the heater, you must have a minimum of 5-7 outlets open at all times.

Q Can I get cooling through the same system?

A Yes, this is called Add-On Air Conditioning. The ducting must be up-sized to allow for the larger airflow that Air Conditioning requires.

Q My house has a concrete slab floor, does it work through the roof?

A Yes, it is common to have the system installed in the ceiling. Mercury Heating and Cooling will make sure that the system is adjusted to reflect this, i.e. the sizing of the fan has to be large enough to blow the heat down to the ground, the outlets must allow the air to flow through freely so it can reach a low level and the "Return-Air grill" should be also be at a low level.

Q Which is the best model for me?

A All heaters have a star rating to indicate operating efficiency. The more stars the cheaper it is to run, but the greater the initial purchase cost. So to recommend a specific model, Mercury Heating and Cooling will assess how long you intend to live at the house, how large the house is, what temperature and how often you intend on using the system.

Q Can I get a remote control?

A Yes, but because the system judges the house temperature via the thermostat inside the controller, we recommend the controller be mounted on a wall in your main living area so that it can read and communicate the correct information to the actual heater.

Q What if I just want to heat one room or area?

A Radiant Panel heaters or Fan Forced Heaters are designed to heat a single area. There are different sizes to match any room size.

Q What about service or maintenance?

A The "Return Air filter" should have a vacuum run over it regularly and the unit requires a technician to service it every 3 years, but Mercury Heating and Cooling will contact you when this falls due.
