NB: Reverse cycle air-conditioners are an effective solution as they provide both cooling and heating and are highly efficient. However, unlike gas heaters, their heating capacity will reduce with colder ambient temperatures, which is especially relevant for homes in colder areas. Discuss with your installer things like the local climate, the size of your house, its orientation and construction (such as glazing, doors, insulation), and your expectations, so a system with the appropriate capacity can be selected.
